Sustainable Development Goal 6 Synthesis Report on Water and Sanitation 2018 2018 Sustainable Development Goal 6 Synthesis Report on Water and Sanitation The world is not on track to reach Sustainable Development Goal 6 (SDG 6) on Water and Sanitation by the deadline set for 2030. Today, billions of people lack safe water, sanitation and handwashing facilities. Ecosystems and water sources are becoming more polluted, and funding for water and sanitation services is inadequate. In addition, governance and delivery systems are weak and fragmented. UN-Water’s Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation builds on the latest data available for the 11 SDG 6 global indicators. Representing a joint position from the United Nations family, the report offers guidance to understanding global progress on SDG 6 and its interdependencies with other goals and targets. It also provides insight into how countries can plan and act to ensure that no one is left behind when implementing the 2030 Agenda for Sustainable Development.

Progress in nutrition, health, education, work, equality, environmental protection and international cooperation are all related to the availability and sustainable management of water and universal access to effective systems for disposing of our waste. These are the objectives of Sustainable Development Goal 6. If we remain off track to deliver on SDG 6 then we jeopardize the entire 2030 Agenda for Sustainable Development. Yet, today, billions of people still lack access to safe water and sanitation, resulting in needless deaths, chronic disease, missed education and reduced productivity. At the same time, demand for water -- from agriculture and industry as well as domestic use -- is rapidly rising and water pollution and ecosystem degradation are being made worse by increasing amounts of untreated wastewater. And all of this is happening against a backdrop of climate change, which is playing havoc with the predictability of our most precious resource. What this report makes clear is that we must tackle weak funding, planning, capacity and governance of water and sanitation services as a top priority. New partnerships are needed, involving stakeholders within and beyond the water and sanitation sectors, to address these fundamental issues, balance competing needs, and act to get SDG 6 back on track. Data and smart technologies must be embraced so interventions can be as effective as possible and progress tracked over time. The High-Level Panel on Water convened by the United Nations and the World Bank issued their final report Making Every Drop Count on World Water Day. The report’s recommendations set forth a global agenda for water action to help countries reach the SDG 6 targets. As we intensify our efforts to achieve SDG 6 and advance implementation of the International Decade for Action on Water, we should be guided and inspired by the fact that our work will lay the foundations for a healthier, fairer, more stable, equitable and prosperous world. The United Nations stands ready to support countries and their partners to achieve SDG 6 across the globe.

The water sector is struggling to improve water resources management and to increase the coverage and quality of water and sanitation services. Some of the many challenges are practical actions that provide the “visible” side of water, such as installing taps and toilets, building reservoirs, drilling boreholes, and treating and reusing/recycling wastewater.

This report presents data collected through the Integrated Monitoring Initiative for SDG 6 coordinated by UN-Water and uses complementary sources of data and information to analyse policy linkages among different SDG targets and indicators in an integrated fashion. By assessing the global baseline status of SDG 6, it pro- vides Member States with an overview of water and sanitation issues in the context of the wider 2030 Agenda, and outlines what needs to be done to accelerate progress towards this goal.

The United Nations General Assembly and the Human Rights Council reaffirmed the human rights to safe drinking water and sanitation in 2015 (United Nations, General Assembly, 2015b; United Nations, Human Rights Council, 2016). All States have an obligation to move as quickly as possible towards full realization, using the maximum available resources, and to take active measures to reduce and eliminate existing inequalities, without discrimi- nation. The criteria of accessibility, availability, quality, acceptability and affordability are increasingly reflected in the frameworks used for monitoring water and sanitation at national and global levels. A human rights approach requires that individuals have rights to adequate water and sanitation services. It also requires services to be pro- vided in a way that respects the environment and does not negatively affect downstream communities or future generations (de Albuquerque, 2014).

BOX 3 IWRM “IWRM is a process which promotes the co-ordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compro- mising the sustainability of vital ecosystems.” (GWP, 2000a). IWRM is a process; therefore, it does not offer a universal approach to water management. Water resources, de- velopment priorities, and social and economic issues are all location and context specific. Country or water basin planning may differ, but IWRM provides a common approach, and experience shows that there are common fea- tures to all. These include: a strong enabling environment; sound investments in infrastructure; clear, robust and comprehensive institutional roles and responsibilities; and effective use of available management and technical instruments. These are the practical elements of implementing IWRM (Lenton and Muller, 2009). 27 The Statistical Commission approved the official list of tistical Commission in 2020 and 20253.

It calls for increased support for data collection and capacity-building in Member States to establish national and global baselines. IAEG-SDGs has classified the 232 global indicators based on methodological development and data availability. Tier I indi- cators have established methods, standards and data available for at least 50 per cent of the global population and 50 per cent of countries. Tier II indicators have established methods and standards, but data are not regularly produced by countries. Tier III indicators are those for which methods and standards are still being developed.

BOX 4 Monitoring safely managed drinking water services in Kenya Monitoring safely managed drinking water services requires data on the number of people using improved drinking water sources, and the number of those sources accessible on premises, available when needed and compliant with drinking water quality standards. The Water Services Regulatory Board in Kenya was established to regulate the water services subsector, following passage of the Water Act in 2002. The Board has since published nine annual reports (IMPACT reports) that ana- lyse utility performance based on nine key performance indicators. The first IMPACT report referred to compliance with residual chlorine targets. Subsequent reports have included compliance with bacteriological parameters, which were used to calculate SDG baselines in urban areas. Performance on the Board composite drinking water quality indicator increased to 92 per cent by 2014/2015 (WASREB, 2018). IMPACT reports also publish data on number of hours of water supply per day, by utility, which is an indica- tor of water availability when needed. In addition, two household surveys in Kenya directly asked household respondents about drinking water availability. A demographic and health survey in 2003 (supported by the United States Agency for International Development) found that 55 per cent of urban households used impro- ved sources from which water was “usually always available” (CBS, MOH and ORC Macro, 2004). Performance monitoring and assessment surveys conducted in 2014 and 2015 (supported by Johns Hopkins University) found that nearly three quarters of urban households were using improved sources from which water was “avai- lable when expected” (Johns Hopkins University, n.d.). However, multiple surveys conducted from 2000 to 2015 showed that only 55 per cent of households in urban areas had water supplies located on premises in 2015 (WHO and UNICEF, 2017a). Out of the three elements of accessibility on premises, availability when needed and compliance with drinking water standards, the first element was the lowest and determined an estimate for safely managed drinking water services. Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation 36 Chapter II. Global Baseline Status of Targets and Indicators Indicator 6.1.1: Proportion of population using safely managed drinking water services Custodian agencies: WHO and UNICEF Introduction A safely managed drinking water service is defined as provid- ing drinking water from an improved source that is accessible on premises, available when needed, and free from faecal and Global drinking water coverage (per cent) in 2015 priority chemical contamination. WHO/UNICEF JMP produces internationally comparable es- timates based on official data from national statistics offices and other relevant authorities. As the data sources used for dif- ferent service-level parameters may not be the same, it is not always possible to determine which households or populations meet all three of the service-level criteria (accessible on prem- ises, available when needed and free from contamination). In- stead, safely managed drinking water services are calculated at the urban and rural levels by taking the minimum of the three service-level parameters. National estimates are generated as weighted averages of the urban and rural estimates, using population data from the latest report of the United Nations, De- partment of Economic and Social Affairs, Population Divisiona. Seven out of 10 people used safely managed drinking water in 2015. Source: WHO and UNICEF (2017a). Key messages • Five billion people use a safely managed drinking water service. • Estimates for safely managed drinking water are available for 96 countries and four out of eight SDG regions. • One billion people use a basic drinking water service. • Eight hundred and forty-four million people still lack even a basic drinking water service. • Two hundred and sixty-three million use a limited service, and 159 million still collect drinking water directly from surface water sources. • Seventy-four per cent of the global population use improved water sources accessible on premises, 79 per cent have water when needed and 73 per cent drink water free from contamination from surface water sources. 37 Updated JMP ladder for global monitoring of drinking water SERVICE LEVEL DEFINITION Drinking water from an improved water source that is located on premises, available when needed and SAFELY MANAGED free from faecal and priority chemical contamination Drinking water from an improved source, provided collection time is not more than 30 minutes for a BASIC round trip, including queuing Drinking water from an improved source for which collection time exceeds 30 minutes for a round LIMITED trip, including queuing UNIMPROVED Drinking water from an unprotected dug well or unprotected spring SURFACE WATER Drinking water directly from a river, dam, lake, pond, stream, canal or irrigation canal Note: Improved sources include: piped water, boreholes or tubewells, protected dug wells, protected springs, rainwater, and packaged or delivered water.

Global Baseline Status of Targets and Indicators Challenges, opportunities and policy implications Achieving universal access to safe and affordable drink- ing water by 2030 presents a huge challenge for all countries, not just those with low incomes. It is con- sistent with the broader transformative ambition of the 2030 Agenda to “end poverty in all its forms” and to “shift the world on to a sustainable and resilient path”. Target 6.1 challenges Member States to address the “unfin- ished business” of extending services to those popu- lations who remain unserved, and also to progressively improve the quality of services received. It also implies going beyond the household and considering access to services in schools, facilities and other institutional set- tings. The commitment to leave no one behind will re- quire increased attention on the needs and priorities of disadvantaged groups and deliberate efforts to monitor the reduction and elimination of inequalities in drinking water services. Each government must establish its own targets, taking into account national circumstances. In those countries where a large proportion of the population still lacks even a basic drinking water service, the initial focus Internally Displaced Persons (IDPs) at the Nifasha Camp will remain on ensuring that everyone has access to an in North Darfur, have access to water only two hours in the improved drinking water source and reducing the time morning, not enough time for all to be fully provided. spent (primarily by women and girls) collecting water.

BOX 5 Monitoring safely managed sanitation services in Ecuador Levels of basic sanitation services are generally high in Ecuador, but national data on the quality of these services were scarce. Therefore, the National Statistical Office (Instituto Nacional de Estadística y Censos) collaborated with the World Bank Global Water Practice and WHO/UNICEF JMP to pilot a new module in the Encuesta de Empleo, Desempleo y Subempleo, to track progress for SDG targets 6.1 and 6.2, in December 2016. Households were asked questions about sanitation facilities, with interviewers also asking to test drinking water quality and observe handwashing facilities. New sanitation questions focused on the management of on-site sanitation facilities (septic tanks and latrines), asking where effluent from septic tanks is discharged and whether latrines and septic tanks have been emptied. WHO/UNICEF JMP set a baseline for safely managed sanitation services by combining information on management of on-site sanitation facilities with data from municipalities on wastewater treatment. Further work is needed to verify administrative data on wastewater for households connected to sewer networks and to establish mechanisms for determining the extent to which excreta from emptying septic tanks are being treated.

Global Baseline Status of Targets and Indicators Indicator 6.2.1a: Proportion of population using safely managed sanitation services, including a handwashing facility with soap and water Custodian agencies: WHO and UNICEF Introduction Global sanitation coverage (per cent) in 2015 Use of a safely managed sanitation service is defined as use of an improved facility that is not shared with other households, and where excreta are safely disposed of in situ or transported and treated off site. WHO/UNICEF JMP produces internationally comparable es- timates based on national data sources. Data on improved sanitation facilities are routinely collected in household surveys and censuses, and may include information on sharing sani- tation facilities and emptying on-site sanitation facilities. Data on wastewater and faecal sludge treatment from on-site san- itation systems are increasingly collected by regulators, minis- tries, utilities, municipalities and other government institutions with the authority for oversight of service delivery. Safely man- aged sanitation services are calculated by adding together the populations using on-site systems where excreta are treated in situ or transported and treated off-site, and those with sewer connections which lead to excreta receiving at least secondary treatment. National estimates are generated as weighted aver- ages of the urban and rural estimates.a Two out of five people used safely managed sanitation services in 2015. Source: WHO and UNICEF (2017a).

Global Baseline Status of Targets and Indicators Challenges, opportunities and policy implications Achieving universal access to adequate and equita- ble sanitation and hygiene by 2030 represents a major challenge in many parts of the world. Target 6.2 calls for countries to end open defecation and to ensure that everyone has access to a basic latrine or toilet, and also to put in place systems for safe management of the ex- creta produced. It highlights the importance of hygiene, which has previously been neglected in national and global targets and calls for special attention to the needs of women and girls. The proportion of the global population practising open defecation decreased from 20 to 12 per cent between 2000 and 2015, but faster progress will be required to end open defecation by 2030.

BOX 6 Assessment of water quality worldwide With the limited water quality monitoring data available, the recent World Water Quality Assessment (United Nations Environment Programme, 2016) employed a modelling approach. It concluded that: pollution in Latin America, Africa and Asia increased between 1990 and 2010 because of growth in wastewater loadings to rivers and lakes. As an example, organic pollution (measured as biochemical oxygen demand) worsened in more than half of river stretches. Pollution increased to a severe level or was already severe and had worsened by 2010 in a subset of these river stretches. Howe- ver, most rivers are still in good condition, and there are great opportunities for reducing further pollution and restoring water quality.

UN Photo/Evan Schneide Key messages • Preliminary estimatesa for domestic wastewater have been made for 79 countries. They are from mainly high- and-middle-income countries and exclude most of Africa and Asia. Insufficient data are available to make estimates for industrial wastewater. • Seventy-one per cent of domestic wastewater flow is collected in sewers, 9 per cent is collected by septic tanks and the remaining 20 per cent is not collected. • Fifty-nine per cent of all domestic wastewater flows is collected and safely treated. The untreated 41 per cent presents risks to the environment and public health. • Seventy-six per cent of domestic wastewater flows collected in sewers is safely treated. • Eighteen per cent of domestic wastewater flows generated by households with on-site facilities is safely treated in septic tanks". • Estimates should be considered as upper limits because data are skewed towards higher-income countries, and there are data gaps on treatment performance, other sources and sinks of wastewater. • Data on industrial discharges are poorly monitored and seldom aggregated at national level. • Comprehensive reporting on indicator 6.3.1 is impeded by major data gaps relating to on-site treatment of domestic wastewater. • Disaggregation of pollution load by source according to households, services and industry (which can be further disaggregated by International Standard Industrial Classification (ISIC) codes), will assist in identifying heavy polluters and consequently in applying the polluter pays principle to improve treatment. • A subindicator on reuse would respond to the full aspirations of indicator 6.3.1, and would encourage better assessment of reuse potential, in support of target 6.4 on water scarcity.

Note: “Not treated” wastewater may include wastewater that does not need to be treated before being discharged. Insufficient data are available to estimate treatment of industrial wastewater flows to sewers and direct to the environment. In most countries, discharge permit records are kept at the municipal level or in environmental protection agencies. They are seldom aggregated and reported at the national level. Collection and aggregation of permit data sorted by ISIC code are needed for complete reporting on indicator 6.3.1 (this could be achieved by issuing permits and ensuring that industries are compliant). Eurostat industrial emission data for 13 countries illustrate potential data sources for the industrial component of indicator 6.3.1. However, data should be interpreted with care as they could include as “untreated” wastewater that does not need to be treated before being discharged and which may constitute a substantial share. Combining the domestic and industrial components into a single indicator may be possible at a later stage when data become available on pollution loads expressed as the five-day biochemical oxygen demand for domestic and industrial discharges.

Reuse of wastewater in Arab States Data source: League of Arab States, UNESCWA and ACWUA (2016). Target 6.3 calls for a substantial increase of safe reuse of wastewater. Data on the use of wastewater and sludge are routinely collected in some regions to inform responses to water scarcity and pollution. Including a subindicator on reuse at the country and regional levels or during the 2020 revision of the SDG indicator framework would address the target more completely. Definitions of “safe reuse” for monitoring purposes are needed. Levels of treatment required should correspond to the level of risk to human health and the environment for each reuse type. The arid Arab States have proactive policies that address water scarcity and monitor progress. Jordan, Kuwait and Oman use at least secondary treatment prior to water use in agriculture. Other countries still have significant proportions of untreated wastewater. These represent opportunities to increase treatment and productive use for irrigation and groundwater recharge.

Freshwater pollution is prevalent and increasing in many parts of Latin America, Africa and Asia. The lack of water quality monitoring in many parts of the world does not allow for an exact global estimate of water pollution. • “Monitoring programmes can be perceived as expensive, but compared to the relative value of the water resources, and the savings made by making science-based decisions, these costs are minimal” (Lovett et al. 2007). • Increasing population and economic activity can propel a substantial increase in water pollution due to the emphasis on economic activity at the expense of environmental quality. • Public concern is often the instigator of change. There is pressure on relevant authorities to respond to rising pollution by initiating control measures aimed at reducing the pollution increase. If control measures are sufficient, the intensity of water pollution peaks, then levels of organic pollution, nutrient loading and pathogen contamination diminish. • Water quality problems persist, even in developed countries, including the continued loss of pristine quality water bodies and also effects associated with changes in hydromorphology, the rise in emerging pollutants and the spread of invasive species. • The first figure on the next page highlights various pressures on water quality as they rise and fall relative to increasing development. Actions can be taken to mitigate or avoid the effects, once drivers are identified. The main technical options for avoiding water quality deterioration are pollution prevention, treatment of polluted water, safe use of wastewater, and restoration and protection of ecosystems.

BOX 7 Assessing water scarcity in irrigated agriculture Irrigated agriculture is one of the main subsectors causing water scarcity in an increasing number of regions. The figure below shows estimated water stress in major river basins expressed as a percentage of incremental evaporation due to irrigation over groundwater and surface water resources. These results were generated by GlobWat, a freely available global soil water balance model developed by FAO and designed to assess water use in irrigated agriculture. Water balance is calculated using a two-step process. The first stage is a “vertical” water balance that includes evaporation from in situ rainfall (“green” water) and incremental eva- poration from irrigated crops. The second stage is a “horizontal” water balance that determines discharges from river (sub)basins, taking into account incremental evaporation from irrigation, open water and wetlands (“blue” water).

This has strong synergies with sustainable food production (SDG 2), economic growth (SDG 8), infrastructure over time and industrialization (SDG 9), cities and human settlements (SDG 11) and consumption and production (SDG 15). Custodian agency: FAO Introduction Water withdrawal by sector in the world (per cent), 2010 This indicator is designed to assess the economic and so- cial use of water resources in terms of the value added when water is used in different sectors of the economy. It includes losses that occur in distribution networks. Water-use efficiency is defined as the gross value added per unit of water used, expressed in US$/m3. It can help formulate water policy by focusing attention on those sec- tors or regions with low water-use efficiency, and on how to transfer successful actions from sectors or regions where water-use efficiency is much higher. This is a blue water indicator, meaning that it does not take into account the direct use of rainfall. Agriculture accounts for 69 per cent of annual water withdrawals. Data source: FAO (2016). Key messages • The rationale consists of providing information on efficiency of the economic and social usage of water resources. • Interpretation would be enhanced by using supplementary indicators at country level, including irrigation efficiency and municipality network efficiency. • Water-use efficiency is strongly influenced by the economic structure and the proportion of water-intensive sectors. • Change in water-use efficiency is influenced by “real” improvements and deteriorations, as well as by changes in economic and social structure. • Increasing values in time series indicate decoupling of economic growth from water use. This does not necessarily indicate decline in total water use or a reduction in the impact of water use (indicator 6.4.2). • Preliminary data show that water-use efficiency accounts for 15 US$/m3 globally, with country values ranging from about 2 to 1,000 US$/m3. 69 Water abstraction and GDP in the United States from 1960 to 2010 The figure below shows an example of decoupling.

Global Baseline Status of Targets and Indicators Water-use efficiency (US$/m3) While the map below shows substantial differences among regions in terms of aggregated water-use efficiency, it indicates that countries at a different level of general development have comparable values of water-use efficiency. This is because the indicator takes into account a combination of economic size and water use. As water use generally increases with economic development, it is difficult to predict the outcome based on simple hypotheses. However, the actual indicator is based on the change of water-use efficiency over time, which will be computed at the country level. Data for computation are not yet available.

How- ever, during the MDG period, this indicator only accounted for water use due to human activities. Environmental flow requirements are now also explicitly factored in as an impor- tant water user. Thus, water stress is defined as the ratio of total freshwater withdrawn by all major sectors to the total renewable freshwater resources, including environmental water requirements, and is expressed as a percentage.

The situation will likely worsen as populations and the demand for water grow, and as the effects of climate change intensify. • Water stress affects countries on every continent, and hinders the sustainability of natural resources, as well as economic and social development. • Estimates for the level of water stress are available for 171 countries and for all SDG regions. Thirty-one countries experience water stress between 25 and 70 per cent, and 22 countries are above 70 per cent and are considered to be seriously stressed. Eleven countries are above 100 per cent and include Libya, Saudi Arabia, United Arab Emirates and Kuwait, where the demand for freshwater is largely being met by desalination. • The global average water stress is 11 per cent, but there are significant differences among countries and regions, which global and regional assessments hide. Water stress values at the national level can hide differences between wet and dry areas of a country. One example is the large difference between the humid Amazon basin and the dry Pacific coast in Peru. • Regions with the highest water stress are Northern Africa and Western Asia (79 per cent) and Central and Southern Asia (66 per cent). • Sub-Saharan Africa has a low level of water stress at 3 per cent, but this regional value hides the large differences between the wetter north and drier south.

Level of water stress The map above shows the level of water stress estimated with data from AQUASTAT. Areas usually interpreted as very dry, like the Sahel region, appear to have low levels of stress, similar to more humid zones such as the Congo basin and Borneo. This is not contradictory. The indicator is based on the amount of water actually withdrawn in each country, which is generally low. This can be seen in the map below, which shows the proportion of cultivable land equipped for irrigation. The values mean that countries Data source: FAO have scope for improving and increasing their water supply, for agriculture, industry and (2016). households, within the sustainable use of resources. This is a call for more investments in infrastructure and education and should not be interpreted as a denial of the huge problems of water supply and access that many people in those countries actually face. 73 Levels of water stress by region (per cent), 2000–2014 Data source: FAO (2016).

These will then provide decision makers with the information they need to orient their development choices. BOX 8 “Saving” water on irrigation schemes in the corn belt of western United States The western United States corn belt includes approximately 7.3 million hectares cultivated with maize. About 43 per cent of this area is irrigated and accounts for 58 per cent of the total annual maize production. Data on maize grain yield, applied irrigation, irrigation system and nitrogen fertilizer rate collected over a three-year period (2005–2007) from commercial farms concluded that water savings can be made from changes to the irrigation system and irrigation ma- nagement. While sprinkler and subsurface drip irrigation have the potential to increase irrigation efficiency (see footnote) when compared to gravity surface irrigation systems, irrigation schedules based on real-time crop requirements, soil water monitoring and short-term forecasts also appear to be good options. Scheduling irrigation based on soil water content and crop requirement could produce water savings up to 35 per cent with no yield penalty in eastern Nebraska, compared with standard farming practices. Centre pivot systems used 36 per cent less irrigation water than gravity sur- face irrigation to achieve the same yield, and conservation tillage required 20 per cent less irrigation water than conven- tional tillage. Crop residues under conservation tillage may diminish irrigation requirements by increasing precipitation storage efficiency and by reducing direct soil evaporation and surface run-off. Source: FAO (2012a). Note: “Irrigation efficiency” in this context is defined as water consumed by the crop divided by the amount withdrawn from a water source, and not as defined in indicator 6.4.1. Improvements in irrigation efficiency do not always directly translate into water savings. Research shows that farmers who “save” water tend to increase their irrigated area rather than give the water back for others to use. 75 E.

BOX 9 Putting IWRM into practice Having a low human development index (HDI) does not necessarily constrain countries from putting IWRM into practice. Eight African countries with a low HDI reported medium to high levels of IWRM implementation, with scores ranging from 53 to 63: Benin, Burkina Faso, Mali, Mozambique, Senegal, Swaziland, Uganda and Zimbabwe. They reported medium to high implementation of policies, laws and plans (65) and institution and stakeholder participation (69). Most of these countries reported having high national institutional capacity and coordination among sectors, high levels of stakehol- der participation at national and local levels, and regular opportunities for private sector involvement in water resources development and management. However, they reported much lower levels of implementation for financing (41), which typically hindered implementation of management instruments (54). With the exception of Burkina Faso, these countries reported that the national budget for investment in water resources development and management, including infrastructure, was either insufficient to cover planned investments, or budget was allocated but not disbursed.

Global Baseline Status of Targets and Indicators BOX 10 Positive steps towards transboundary cooperation Many countries recognize the importance of adopting basin-wide agreements. For example, an agreement between Ukraine and the Republic of Moldova, on cooperation in the field of protection and sustainable development of the Dnies- ter River Basin, was adopted in 2012 and entered into force on 28 July 2017 (UNECE, 2017a). Similarly, Mozambique and Zimbabwe are currently negotiating operational arrangements for the Pungwe, Save and Buzi Rivers (IUCN, n.d.). The 1944 Treaty between Mexico and the United States for the Utilization of the Waters of the Colorado and Tijuana Rivers and of the Rio Grande has evolved to better account for transboundary groundwater, restoration in the Colorado Delta and drought management (IBWC, n.d.). The 1995 Mekong Agreement and Commission has proven to be an important platform for the countries of the lower Mekong region to exchange data and information and to develop joint plans and programmes. This has led to a better collective understanding of the social, economic and environmental dynamics of the basin and brought countries together to consider the benefits and potential impacts of existing and planned infrastructure projects (MRC, n.d.).

Key messages • In 2017/2018, the global average degree of implementation of IWRM was 48 per cent, corresponding to medium low, but with great variation among countries. • More than 80 per cent of countries (157) reported on IWRM implementation, with strong representation from all regions and levels of development. • Comparisons with earlier surveys in 2007 and 2011 show that while modest progress is being made, most countries will not achieve indicator 6.5.1 by 2030 at current rates of implementation. • Governments and external support agencies should learn from experience and increase implementation efforts, to ensure accelerated progress and positive outcomes. • Attention should be given to building on IWRM monitoring and reporting, to address barriers to progress.

Global Baseline Status of Targets and Indicators IWRM implementation (per cent) in 2017/2018 Indicator definition Indicator 6.5.1 measures the degree to which IWRM is being put into practice as a score between 0 and 100. The score is determined through a self-assessed country questionnaire, with 33 questions split into four sections: policy, laws and plans; institutions and participation; management instruments; and financing.a Each section is divided into two subsections, addressing the “national” and “other” levels. Each country assigns each question a score from 0 to 100. The score selection is guided by descriptive thresholds. For each question, countries are encouraged to provide the reasoning behind their score. These measures help to increase the objec- tivity of the questionnaire, and the ability to subsequent- ly compare and better understand the scores, as well as track progress over time. Question scores are averaged to provide the overall score for indicator 6.5.1. Thirty-eight per cent of countries reported at least medium-high IWRM implementation in 2017/2018.

Status of IWRM implementation in countries in 2017/2018 In 2017/2018, 62 per cent of countries reported medium-low IWRM implementation or lower. Accelerated progress is needed in most regions to achieve the target. Data source: United Nations Environment Programme-DHI Centre (2018). 79 Each region contains examples of countries with at least medium-high implementation, although regional differences exist. This indicates that the level of development need not be an absolute barrier to progress, but it is an influencing factor.

This value suggests that a significant effort is needed to ensure that operational arrangements are in place for all transboundary waters by 2030. • Seventeen countries report operational arrangements in place for all their transboundary basins, 14 of which are in Europe. • An assessment of SDG indicator 6.5.2 across the four criteria of operationality demonstrates considerable diversity in the types of transboundary water arrangements that countries have entered into and the joint bodies established. • Countries highlight the challenges in developing transboundary cooperative arrangements as including: power asymmetries among countries; fragmentation in national legal, institutional and administrative frameworks; lack of financial, human and technical capacity; and poor data availability, especially in relation to TBAs and their delineation. 81 Geospatial localization of transboundary rivers, lake basins and aquifers and national borders Two hundred and eighty-six transboundary rivers and lakes, and 592 TBAs, are shared by 153 countries.

Number of respondent countries to SDG indicator 6.5.2 questionnaire in 2017/2018 As of 28 February 2018, 107 countries had reported during the first reporting exercise for SDG indicator 6.5.2. Reporting must be viewed as a national perspective. Efforts have been made to harmonize the process of data collection, and to consider relevant international data sources, such as the Global Environment Facility Transboundary Waters Assessment Programme and UNESCO International Hydrological Programme (IHP) Internationally Shared Aquifer Resource Management Initiative (ISARM). However, data provided by the countries have been prioritized where discrepancies remained between international data sources and national data.

Out of the 19 countries in sub-Saharan Africa, 12 show that at least 50 per cent of their transboundary basins are covered by operational arrangements. For transboundary rivers and lakes only, 18 out of 27 countries report at least 75 per cent coverage; for TBAs, only 5 out of 18 meet this threshold. Countries in Europe and Northern America show the highest levels of transboundary cooperation. Out of the 24 countries considered, 21 report an indicator value of at least 75 per cent. Operational arrangements are absent in many basins in Northern Africa and Western Asia and in Latin America and the Caribbean. Data are only available for 2 out of 24 countries sharing transboundary waters in Central and Southern Asia, and Eastern and South-Eastern Asia.

The aim was to improve governance and management of TBAs using a multidisciplinary approach. The insights and knowledge gained through ISARM led UNESCO-IHP to undertake the first baseline multi-criteria assess- ment of 199 TBAs worldwide under the Transboundary Waters Assessment Programme funded by the Global Environment Facility. The methodology developed allows for comparative analysis and prioritization of risks and interventions through a set of indicators. This methodology was improved to include all relevant TBA aspects required for joint decision-making and TBA mana- gement in the Governance of Groundwater Resources in Transboundary Aquifers project, funded by the Swiss Agency for Development and Cooperation. This was applied to an in-depth assessment of the Stampriet Transboundary Aquifer System shared by Botswana, Namibia and South Africa, combining science and water diplomacy to facilitate multilevel and interdisciplinary dialogues to foster cooperation. The Governments of Botswana, Namibia and South Africa established a Multi-Country Cooperation Mecha- nism for the management and governance of the Stampriet Transboundary Aquifer System. This was the first of its kind to be nested in a river basin organization, fully capturing the IWRM approach and directly contributing to the implementation of SDG target 6.5 at national and transboundary levels.

Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation 88 Chapter II. Global Baseline Status of Targets and Indicators BOX 13 Regional surface water extent in Central Asia and Southern Europe The spatial extent of surface water was assessed at a regional level using data provided by the Joint Research Centre (JRC) of the European Commission (Pekel and others, 2016). One observation from analysing this data set is a notable decline in surface water extent in Central Asia. The region experienced a decline of 7.4 per cent between 2001 and 2015, which was linked to an increase in total water withdrawals of 229 per cent. Renewable water availability per capita declined by 25 per cent between 2002 and 2014 (see figure below). The situation was different in Southern Europe. Surface water extent increased by 4.5 per cent between 2000 and 2010, which corresponded to a decline in total water withdrawal of 24 per cent and an 11 per cent increase in renewable water availability per capita (2002–2014). However, surface water extent only tells part of the story because the data do not differentiate between artificial and natural water bodies. Although regional trend data show surface water extent increased in many regions from 2001 to 2015, this is likely to be the result of constructing new reservoirs and increases in flood irrigation (Pekel and others, 2016). Research suggests that some artificial reservoirs can damage riparian ecosystems by changing their ecological cycles and biodiver- sity (Rosenberg and others, 1997). Comparison of surface water extent (2000–2015), total water withdrawal (2000–2010) and renewable water availability per capita (2002–2014) Data sources: FAO (2016a); Pekel and others (2016). 89 water-related ecosystems, such as forests and mountains, are Indicator 6.6.1: Change in covered elsewhere in SDGs. the extent of water-related Definition of indicator and methodology ecosystems over time The indicator method defines “extent” as “the size or area Custodian agency: United Nations of something”, thus going beyond spatial area to include Environment Programme other size (quantitative) measures of water-related eco- systems, i.e. quantity, quality and health.

UN Photo/Irwandi M Gade Key messages • Water-related ecosystems underpin and depend on other SDGs, in particular those relating to food and energy production, biodiversity and ecosystems on land and sea. Protecting and restoring water-related ecosystems cannot be achieved without progress on these other goals and vice versa. • The world has lost 70 per cent of its natural wetland extent, including a significant loss of freshwater species, over the last 100 years. Artificial water bodies, such as reservoirs, dams and rice paddies, have been increasing in most regions of the world. • There are currently insufficient data to adequately measure progress towards SDG target 6.6. However, monitoring changes to water-related ecosystems can be supported using Earth observations. Such global data have a significant role to play in supporting countries in monitoring and reporting on indicator 6.6.1. • Protecting and restoring water-related ecosystems refers to actions that include: valuing the benefits and co-benefits provided by water-related ecosystem services; understanding and addressing land-use change impacts on water-related ecosystems; and prioritizing restoration and protection of source watersheds such as forests and critical basins.

Most of the data reported are from 2015 onwards. Countries were asked to select and report on their most significant water-related ecosystems, with the result that some countries reported on most of their water-related ecosystems while others reported on a few. Sixteen countries reported data on basins covering more than 75 per cent of the surface area of their country; two countries submitted data for basins that cover between 25 and 75 per cent; and eight countries submitted data for basins that cover less than 25 per cent. Country example: change in spatial extent of open water Data source: JRC. Trends in the spatial extent of surface water were assessed using the data available from 188 United Nations Member States provided by JRC, to fill data gaps and generate regional analysis. These global data were captured from 1984 to 2015 at 30 m resolution every eight days, and accounted for seasonal fluctuations. This raw data set was processed and packaged into country data sets and shared with national statistics offices. Each country data set comprised annual national spatial extents from 2001 to 2015, percentage change statistics based on five-year averages and graphical depictions of the data.a The figures below show national and regional loss and gain trends in the spatial extent of open water. a From the 188 countries that had Earth observation data available, 36 were not provided with data because they had already submitted nationally derived data. From the resulting 152 coun- tries, 133 national statistics offices had no objection to the data being shared. Twenty-one countries preferred not to validate the data because they were a Tier III indicator or countries wished to use their own geospatial data. 91 Regional analysis: average loss and gain trends of open water Note: This figure presents the regional percentage change in average spatial extent of open water from 2001 to 2015. It is important to note that the JRC data set includes all open water (natural and artificial), and therefore the data capture the spatial extent of water within new reservoirs and areas that have been flooded for irrigation. Wetland extent trend index The concurrent loss in natural wetlands indicates that there may be significant conversion to artificial wetlands or other land-use types such as agriculture. The JRC data do not differentiate between types of surface water and do not capture some of the major areas of vegetated wetland, so they are complemented by the wetland extent trend index, which calculates average trends in natural wetland extent over time. The figure below shows a decline in average wetland extent in all regions, which varies from 12 per cent (Oceania) to 59 per cent (Latin America and the Caribbean, excluding Orinoco and Amazon river basins) for the wetlands sampled. Data sources: Dixon and others (2016); United Nations Environment Programme-WCMC (forthcoming). Note: Regional average trends in natural wetland extent, which is the aggregation of equally weighted marine/coastal and inland wetland trends, relative to 1970. Trends indicate an average percentage decline in natural wetland extent for the sampled localities in the data set.

Regional ODA water- and sanitation-related disbursements for 2011 and 2016 (millions of US$, constant 2016 US$) Data source: OECD (2018). Key messages • Adequate financial resources are critical for achieving SDG 6 by 2030, whether by attracting new sources or better utilizing existing resources. • Total water sector ODA data show that disbursements increased from US$7.4 billion to US$9.0 billion between 2011 and 2016. • Funding has increased across the sector since 2005, with aid for agricultural water resources nearly tripling. However, water sector ODA has remained relatively constant as a proportion of total ODA disbursements at approximately 5 per cent since 2005. • The GLAAS 2017 finance-focused report indicates that government WASH budgets are increasing (annual average rate of 4.9 per cent over inflation); at the same time, over 80 per cent of participating countries report insufficient financing to meet national WASH targets. • There is some evidence that ODA commitments to water and sanitation have declined since 2012, in particular for sub-Saharan Africa, indicating uncertainty in future investments. • Regional changes have varied. Water sector ODA disbursements to sub-Saharan Africa increased by US$711 million from 2011 to 2016, and the region received the largest proportion of country-allocable water sector ODA in 2016 at 33 per cent. Northern Africa and Western Asia followed with an increase of US$497 million in water sector ODA from 2011 to 2016, which allowed the region to reach 20 per cent of the total water sector ODA in 2016. Latin America and the Caribbean and Eastern and South-eastern Asia were the two regions that experienced a decrease in water sector ODA disbursements from 2011 to 2016. Basic drinking water and sanitation systems accounted for nearly a quarter (22 per cent) of total ODA disbursements in sub-Saharan Africa. ODA for large drinking water and sanitation systems remained steady as a proportion of total ODA disbursements from 2011 to 2016, at approximately 40 per cent. 95 About the data Data on the amount of water- and sanitation-related ODA included in government-coordinated spending plans will be The current data included in the monitoring of the in- collected through future UN-Water GLAAS country surveys. dicator are ODA flows from all donors to developing The GLAAS initiative collects data through country surveys countries eligible for ODA in the water sector.

UN Photo/Albert González Farran BOX 14 Improving coordination and disbursement of ODA funding Most countries indicated limited availability of financial reports on external aid expenditures for WASH in 2017. Reasons included: (1) partners reporting only activities and outcomes, but not financial information; (2) direct implementation of projects and programmes by development partners with little reporting or collaboration with national authorities; and (3) other reporting difficulties, including a lack of disaggregation of projects into separate subsectors. Some countries have established coordination frameworks at the national level to encourage improved collaboration among technical and financial partners and national institutions. This collaboration includes development partners, donors and international NGOs, using a database as a key instrument to centralize aid commitments and disbursements that are disaggregated by subsector and regions, and which are updated on a quarterly basis. For example, Madagascar has esta- blished a Permanent Technical Secretariat for the Coordination of Aid. The National Target Programme for Rural Water Supply and Sanitation in Viet Nam disperses affordable finance to households, in the form of low-interest loans through the Vietnam Bank for Social Policies This scheme, which was first a national-level initiative of the government, has evolved to be an effective means for multiple international donors, including the Department for International Development in the United Kingdom of Great Britain and Northern Ireland, to disperse ODA at the local level.

Photo/Katrin Gronemeier Key messages • Data from the 2013/2014 and 2016/2017 cycles of GLAAS have been merged for the purposes of this analysis, taking the latest data points for 110 participating countries. • Over 75 per cent of countries report having clearly defined policies and procedures in place for the participation of service users and communities in planning programmes for drinking water supply (urban: 79 per cent, rural: 85 per cent) and sanitation (urban: 79 per cent, rural: 81 per cent). • Levels of participation remain comparatively low, although most countries report having clearly defined procedures for local participation. Less than 25 per cent of countries report a high level of participation in any subsector. Levels of participation tend to be higher for drinking water supply (22 per cent) and sanitation (21 per cent) in rural areas compared to urban areas (13 per cent and 9 per cent, respectively). • Rural drinking water supply tends to have the highest proportion of countries with defined procedures for participation, among the four subsectors, and urban sanitation has the lowest. This is a result that has been seen consistently since the 2009/2010 cycle of GLAAS. • Eighty-three per cent of 82 countries report having policies and procedures for water resources planning and management, which was added to the GLAAS survey in 2016/2017.

Global Baseline Status of Targets and Indicators BOX 15 Forms of participation Public participation includes the use of procedures and methods to inform, consult and involve local communities and citizens (OECD, 2015). This concept differs from that of stakeholder engagement, which implies, beyond civil society, the involvement of several actors such as governments, the private sector, regulators, service providers, donor agencies and investors. It is possible to distinguish across several forms of stakeholder engagement: from communication, to consul- tation, participation, representation, partnership and co-production. These various forms imply a gradual consideration of stakeholder comments, advice and ideas. Participation means that stakeholders play an active part in decision-making. The risk is that stakeholder views may not necessarily affect final decisions, although they will improve transparency in decision-making. Countries recognize that different forms of participation occur for national processes (e.g. development of laws, regulations and national strategies) versus operational- or community-level processes (e.g. user committees, citizen complaints and tariff reviews). The framework for local participation can be set at the national level, through defining public dissemination, hearing procedures and deadlines for government units, or, where appropriate, by transboundary institutions. Albania, Cos- ta Rica and Peru define public hearing procedures as part of a formal process of tariff regulation. Mexico defines user par- ticipation in the National Water Law, specifically through bodies such as basin councils, groundwater technical committees and irrigation units, as well as federalized programmes. Local participation can take many forms, such as WASH committees at village level, as in Lao People’s Democratic Repu- blic, Rwanda, United Republic of Tanzania and Zimbabwe, or in national workshops as part of developing national WASH policies and strategies as in Costa Rica and Senegal. One recurring aspect of local participation is gender inclusion, where some countries, such as Fiji, Mozambique, Nepal, Peru and Rwanda, define a minimum percentage of female participation in user committees and encourage active female participation in all phases of the project cycle.

BOX 17 Benefits of cooperation in the Drina River basin The Drina River basin, a tributary of the Sava River basin, is shared by Montenegro, Serbia, and Bosnia and Herze- govina. This water-rich river basin is characterized by untouched landscapes and good biodiversity. The area has a high level of unemployment among youth, which is driving migration towards large cities as well as other countries. The population of the Drina basin was severely affected by floods in 2010 and 2014. Key economic activities in the basin include power generation, small-scale agriculture and nature-based tourism. Hydropower generation is key in contributing to energy security, delivering on international commitments on green- house gas emission reductions and electricity export potential. Groundwater represents the main water supply. Biodiversity is significant, particularly within the upper parts of the basin, which are home to rare and endangered species such as brown bear, wolf, chamois, wildcat and otter (UNECE, 2017b). A multidisciplinary nexus assessment was carried out in the Drina basin to identify (through a transboundary dia- logue) key linkages among energy, water, land and ecosystem resources (UNECE, 2015b). Its purpose was to assist sector authorities and stakeholders. Economic benefits of transboundary cooperation were identified as increased electricity production (e.g. optimizing water release regimes), increased agricultural production (e.g. by improving irrigation systems though coordina- tion and exchange of experience), reduced damage from floods and droughts (e.g. by better modelling of flood and drought risk, developing protective infrastructure and cooperation in flow regulation) and development of the tou- rism sector. Other benefits included increased energy trade and integration and energy security, increased numbers of people employed due to cross-border economic activity, reduced rural–urban migration, reduced economic and human costs of floods, increased resilience of local communities to climate change, and protection of water quality and ecosystems (e.g. through improved wastewater treatment and solid waste disposal). The Sava River Basin Commission and its legal framework were identified as important for promoting cooperation at the basin level. However, improvements in governance at many levels (e.g. improved coordination among sectors within each country, more formal cooperation arrangements among countries, broader engagement of stakehol- ders and greater focus on compliance) are critical, together with the needs for technical solutions and a coordinated basin-wide investment strategy (UNECE, 2017b). 109 “Inequality and the need to leave no one behind are persistent problems with no clear solutions. Equal access to sufficient safe and affordable water, and adequate and equitable sanitation and hygiene, can mean the difference between prosperity and poverty, well-being and ill-health, and even living and dying.” Such findings reflect previous estimates, which suggest that between prosperity and poverty, well-being and ill-health, only 158 of the world’s 286 transboundary rivers, lakes and and even living and dying.

Between urban and rural populations Rural communities lag behind the urban sector in pro- viding access to basic water and sanitation facilities, although there is good progress at the global level. Some 159 million people still collected drinking water from distant surface water sources, mostly rural com- munities in Central and Southern Asia and sub-Saha- ran Africa, in 2015. A similar global picture is evident for sanitation, where 892 million people still defecated in the open, with the majority again residing in rural communities (WHO and UNICEF, 2017b). The World Bank’s WASH Poverty Diagnostics Initiative graphically shows these differences (figure 9). 113 Figure 9.

Enabling and accelerating progress BOX 18 SWA collaborative behaviours SWA identified four collaborative behaviours that could improve long-term sector performance and sustainability, if jointly adopted by governments and development partners: • Enhance government leadership of sector planning processes • Strengthen and use country systems • Use one information and mutual accountability platform built around a multi-stakeholder, government-led cycle of planning, monitoring and learning • Build sustainable water and sanitation sector financing strategies that incorporate data on taxes, tariffs and transfers, as well as estimates for non-tariff household expenditure Adopting these behaviours can improve accountability and produce better results. Nine indicators were developed to monitor the collaborative behaviours, to improve long-term sector performance and sustainability in the WASH sector. These draw on the success from the health sector and International Health Partnership indicators. The data required for the indicators come from published data and existing monitoring ini- tiatives, such as OECD, GLAAS and World Bank assessments. The following key principles helped to drive indicator development: • Focus on the core element(s) of each behaviour. It is impossible to cover everything with these indicators, although the behaviours can be complex, and so it is important to concentrate on the central issues. • Encourage the WASH sector to measure aspects that have not been measured before. The core elements of the behaviours are difficult to monitor, but this should not prevent the sector from attempting to do so. • Leverage existing monitoring initiatives and adapt tools accordingly in the future. Monitoring behaviours should not put an additional burden on countries for data collection. Source: SWA (2018).

The water utility faced customer payment problems when services and service levels did not meet community expectations. Johannesburg Water responded by offering customers two call-in centres, two walk-in contact centres and contact by mail and email, to address the issue. The utility has benefited enormously from maintaining good customer care and relations. Customers are more likely to inform it of service failures that can be rectified quickly when the utility responds swiftly and provides feedback. Customers are therefore satisfied and more willing to pay for services. This increases cost recovery and the ability of Johannesburg Water to further invest in services.

They are also represented on a citizen’s board that oversees the public utility and its contractors, thus promoting accountability. The Municipal Department of Water and Sewerage has kept up with population growth and expanded services significantly since citizen participation has increased. The percentage of dwellings with access to treated water rose from 94.7 per cent in 1989 to 99.5 per cent in 2002, and the proportion with access to the municipal sewer network grew from 46 per cent in 1989 to 84 per cent in 2002.

BOX 21 Partnership for water and sanitation in Pakistan The Karachi Water Partnership was established as a neutral, multi-stakeholder group unified by a common aim to promote government–citizen collaboration for improved water resources management in the city. The multiple wa- ter management issues confronting the 18 million inhabitants of Karachi were unlikely to be solved without active contribution from all concerned. The partnership has proven to be key for developing change in the management of water and sanitation in Karachi. It was mandated to act through signing seven memorandums of understanding with city-based institutions, inclu- ding the City District Government of Karachi and the Karachi Water and Sewerage Board. More than 300 partners have joined the partnership since its launch, with each one signing a pledge to conserve and better manage water and sewage in homes, in places of work and study, and in public spaces. Water supply and sanitation facilities were provided for over 400 teachers and 8,500 school children in 55 schools, and US$70,000 was raised to create and support the partnership. At the neighbourhood level, the Orangi Pilot Project provided a model for communities to organize themselves around sewer lanes, as part of work on low-cost sanitation, housing, health, education and credit for microenter- prise. Extensive mapping was used to disentangle land ownership, which can cause personal risks in situations of high demand for land. The achievements of local Women and Water Networks has highlighted the role that women play in catalysing change within communities. Establishment of such networks was recognized as a prerequisite for advancing work at the district level. Sources: Global Water Partnership; Orangi Pilot Project. 2.

However, they dropped from US$18.4 billion in 2015 to US$15.1 billion in 2016. ODA and ODF disbursements have also increased and are currently US$13.0 billion (figure 15). Most disbursements came from ODA (68.7 per cent) in 2016. ODA targeted at the water sector has shifted away from grants towards concessional loans since 2005. The percentage of disbursed concessional loans from ODA increased from 39 to 61 per cent in 2016 (OECD, 2017). While ODF investments in the water sector remain un- certain and are a small part of the overall funding total, some countries still rely on external funds, with 11 coun- tries receiving more than 20 per cent of their WASH fi- nancing from these external sources (WHO, 2017a). 9 A part of the rise in ODF commitments from 2000 to 2016 is likely due to incomplete CRS data on Other Official Flow (OOF) commitments in 2000.

BOX 22 Brazil’s National Water Resources Information System The National Water Resources Information System is a large database on water in Brazil. It consists of a set of processes for collecting, organizing and transmitting data and information. The system consolidates water status data from all over Brazil, including reservoir levels, river stream-flows and water quality, as well as information on water users, including urban supply systems, irrigation networks and industries. This means that the quantity of available water is known, together with its quality and the purposes for which it is used. This information is vital for efficient water management. The Brazilian National Water Agency is responsible for coordinating the system and complying with the principles of decentralized data and information uptake and production, unified system coordination and guaranteed access by society. Information is stored in a database and disclosed in the form of interactive maps. All data in the system are publi- cly available and may be accessed free of charge by anyone. There is a metadata portal linked to the system that was set up to organize and systematize geospatial information produced and used by the Brazilian National Water Agency, to ensure it is disseminated and accessible via the Internet. Thirty-eight interactive maps were available in 2016, produced from 144 geoservice layers and associated with 200 different metadata. The system provides input for actions and studies in Brazil, including preparing for environmen- tal economic water accounts and SDGs, especially SDG 6. Source: ANA (n.d.). Figure 18.

BOX 23 Accounting for water Water accounting is about quantifying water resources and uses, much like financial accounting provides infor- mation on income and expenditure. Given that water is a precious and limited resource, it is paradoxical that ac- counting for water receives so little attention. The current lack of nationally and internationally accepted water accounting methods is a serious drawback to water resources planning and water allocation. Many developing countries lack data. Government line departments rarely have access to a common information base when attempting to align water development plans. Different countries in the same river basin often use different databases and systems of measurement, which can seriously hinder effective transboundary water ma- nagement. FAO is currently working towards establishing an accepted system of water accounting. This will go beyond data collection, and will provide a scientific and transparent basis for evidence-informed strategy development, opera- tional decision-making, and targeted communication or awareness-raising programmes. Modern technologies can also help to relieve the burden of data acquisition. These include the use of Earth obser- vations, mobile and basin/field hydrometric sources and information from different water-using disciplines. Re- search is needed to map alternative ways of acquiring data, establish common water metrics and develop methods that better capture the connections among water users, support SDG monitoring and investigate early warning systems for emerging water risks.

Beyond Sustainable Development Goal 6 BOX 24 Transitioning towards sustainable and resilient societies: water and the other SDGs under review at HLPF 2018 SDG 6 is inextricably linked to the other SDGs being reviewed at the annual HLPF in July 2018. The following is a brief overview of some of the linkages and main messages. SDG 6 SDG 7: Water and energy are mutually dependent, with all energy forms requiring water to varying degrees. In turn, water management, including treatment and pumping, requires energy (see the section on “Water and society” below). SDG 6 SDG 11: Cities and human settlements provide basic services to their inhabitants, including drinking water and sanitation. Cities are also increasingly playing a role in the management of water-related ecosystems, including floods and droughts (see “Water and society”). SDG 6 SDG 12: Water is an integral part of consumption and production cycles of food, energy, goods and ser- vices. Managing these processes sustainably is important in protecting the quantity and quality of water resources and using them more efficiently (see “Water and the environment”). SDG 6 SDG 15: Water and land management are closely associated, with activities taking place on land (in- cluding agriculture) using and potentially polluting water resources. Freshwater is also known as terrestrial water, and water is an indivisible part of what is known as the landscape approach. Water is also needed for all the world’s ecosystems to function properly, including those on water, land and in seas (see “Water and the environment”). SDG 6 SDG 17: The MoI SDG is key to success of the 2030 Agenda, and includes partnerships, finance, tech- nology, capacity-building, data acquisition and monitoring, and governance, all essential for SDG 6 achievement (see chapter III). basic WASH services.

Neglected tropical diseases Poor access to WASH is a key contributor to neglected tropical diseases (NTDs). These diseases affect over 1 bil- lion people worldwide in 149 countries and cost developing economies billions of United States dollars a year (WHO, n.d.). People living in areas endemic to NTDs are often the poorest, most marginalized and vulnerable in society. Reducing ine- qualities is at the core of the 2030 Agenda. The WASH sector has a clear role to play in preventing and managing disease by providing WASH services for populations most at risk. Untreated excreta in the environment contributes to the spread of disease, including certain NTDs. For example, tra- choma is the leading cause of preventable blindness world- wide and is responsible for the blindness or visual impairment of 1.9 million people in 41 countries (WHO, 2018b).

Annual estimates of food they live on the margins of food insecurity (FAO, 2011b; 2015b). BOX 25 “Water footprints” in food – a useful concept linking diets with water Over the past 40 years, nutrition has shifted from “traditional diets” (plant based, and high in cereal and fibre) towards “Wes- tern-style” diets (high-calorie foods, livestock products, processed foods, fast foods and bottled soft drinks), particularly in richer countries. Water footprints seek to quantify the amount of blue and green water resources required to produce food. The average Euro- pean diet consumes 3,653 litres per person per day (Vanham and others, 2013). This is considerably more than the average 120 litres per day that a citizen of the European Union uses for drinking, cooking, washing and flushing. Significant proportions of the European Union population are overweight or obese. Citizens are encouraged to eat less meat, sugar, crop oils and animal fats, all of which have large water footprints. They should eat more fruit and vegetables, which are less water intensive to produce, according to dietary guidelines. Such a healthy diet could reduce the region’s water footprint. A shift to a healthy diet has three major benefits: (1) citizens increase their life quality and expectancy, (2) water can be saved and (3) health-care systems can save money. The mounting impact of malnutrition on public health and economic develop- ment costs US$3.5 trillion per year (WHO, 2016). However, decisions should not just be based on water consumption, but also on the sustainability of these water uses. For example, it is important to assess whether the water abstracted from rivers or groundwater (blue water) to produce these food products, contributes to local water stress and anything else that could happen to the land and water used for food production.

Box 26 exemplifies how surface water pollution is of chemical contaminants including naturally occurring ar- dealt with in the Netherlands. BOX 26 Surface water pollution in the Netherlands About 43 per cent of the grassland and 82 per cent of the maize land in the Netherlands was mostly saturated in nutrients due to overfertilization in 1990 (Breeuwsma and Silva, 1992). Nutrient concentrations in surface waters therefore consistently exceeded water quality standards (Oenema and Roest, 1998; Oenema and others, 2007). The Dutch Manure Law entered into force in 1986 in recognition of this problem, and the European Nitrates Di- rective was adopted in 1991, resulting in measures that included a ban on applying fertilizers outside the growing season and an annual maximum limit of 170 kg of nitrogen per hectare applied (Council of the European Commu- nities, 1991). Nutrient pollution rates in the Netherlands are still falling now, but many open surface waters routinely fail to meet environmental quality standards (Rozemeijer and others, 2014). A study by Rozemeijer and others (2014) showed that even though phosphorus concentrations were reduced by 0.02 mg/l per decade, 76 per cent of 167 rivers where agricultural fertilizers were the main cause of pollution still did not meet water quality standards. With recent growth of the livestock sector due to dismantling the milk quota (European Commission, 2015), the Dutch Government has introduced a new and firmer phosphate decree to limit the national dairy population. The amount of phosphate that farmers can produce may not exceed the 2015 reported amounts under the new decree. This resembles policies on carbon dioxide emission rights, in that phosphate rights may be traded among farmers. The case of the Netherlands demonstrates the long-lasting impact that soil phosphorus pollution may have on surface water quality, and the extent of policy, regulation and economic restrictions necessary to prevent further deterioration of the environment. 2. Water-, land- and nature-based Interest is growing in nature-based solutions (NBSs), which use or mimic natural processes to enhance solutions water availability (e.g. soil moisture retention or groundwater recharge), improve water quality (e.g. Terrestrial and freshwater ecosystems are symbiotic. Land- natural and constructed wetlands or riparian buffer based ecosystems depend on freshwater resources in suffi- strips), and reduce risks associated with water-related cient quantity and quality. In turn, activities on land, including disasters and climate change (e.g. floodplain restora- how land is used, influence water availability and quality for tion or green roofs) (SDGs 11 and 13) (box 27) (WWAP people, industry and ecosystems. and UN-Water, 2018).

UN Photo/Mark Garten BOX 27 NBSs for water NBSs provide a means of conserving or rehabilitating natural ecosystems and/or enhancing or creating natural processes in modified or artificial ecosystems. They can be applied at micro (e.g. a dry toilet) or macro (e.g. lands- cape) scales. NBSs include green infrastructure that can substitute, augment or work in parallel with “grey” infrastructure in a cost-effective manner. The goal is to find the most appropriate blend of green and grey infrastructure that maxi- mizes benefits and system efficiency while minimizing costs and trade-offs. However, despite a long history and growing experience in the application of NBSs, there are still many cases where water resources policy and management ignore NBS options – even where they are obvious and proven and effective. Water management remains heavily dominated by traditional, human-built (grey) infrastructure, and the potential for NBSs remains underutilized. Evidence suggests that this is still well below 5 per cent of the total investment in water resources management infrastructure, despite rapidly growing investments in NBSs. NBSs are essential for achieving SDG 6 and other water-related targets, but they can also help to support progress on other aspects of the 2030 Agenda through generating social, economic and environmental co-benefits, including human health (SDG 3), food (SDG 2) and energy (SDG 7) security, sustainable economic growth, livelihoods and decent jobs (SDG 8), ecosystem rehabilitation and maintenance, and biodiversity (SDG 15). Although NBSs are not a remedy, they will play an important role in moving towards a circular economy and in buil- ding a more equitable future for all. Source: WWAP and UN-Water (2018). Forest catchments, which provide much of the world’s freshwater is reduced at the same time as the demand freshwater, are a key provider of NBSs.

Modelled results show that on average, 3.3 per cent of all water resources was polluted by human activities. The effects are low, but widespread, and affect 75 per cent of the population. Some 1,320,000 people (7.3 per cent of the population in 2010) are living in areas where more than 25 per cent of water is polluted. About 250,000 people are in areas with severely polluted water (more than 50 per cent of the human footprint index). Most widespread pollution is low and comes from subsistence agriculture in this area, which makes little use of chemical fertilizers and pesticides. However, untreated municipal wastewater, waste disposal sites and industrial discharges are major point sources of surface water and groundwater pollution in urban areas (Heathwaite, 2010; Ministère de l’Environnement et des Forêts, 2012; NGWA, 2012). Some 22 per cent of cultivated land is irrigated and accounts for 96 per cent of the total water withdrawal. Conver- ting forest land to agriculture may increase water withdrawal (FAO, 2016a). Deforestation correlates with an ave- rage increase of 0.2 per cent in potential water pollution, which could affect 2.2 million people (12.2 per cent of the population). Pollution entering the ocean may also damage coastal habitats such as coral and seagrass, thus affecting fisheries. a The WaterWorld model is a hydrological model that assesses surface water contamination resulting from human activities such as deforestation. The output is the human footprint on water quality indicator (Mulligan, 2009). Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation 146 Chapter IV.

BOX 29 Protected areas can sustain water supplies and aquatic ecosystems Protected areas are one of the most effective tools for maintaining ecosystems in a natural state. They help to maintain water services vital to human welfare and support the rich diversity of aquatic species found in rivers, lakes and wetland ecosystems. Protecting, restoring and sustaining mountain ecosystems, “the water towers of the world”, are particularly impor- tant contributors to water security. People and industries downstream rely on protected mountain ecosystems as a source of freshwater for domestic and economic activities, including small- and large-scale irrigation, hydropower and various industries (IUCN, 2012). About 23 per cent of mountain areas sustains downstream water supplies globally, and another 30 per cent sup- ports supplies to some extent (Viviroli and others, 2007; Egan and Price, 2017). Protected areas provide drinking water for a third of the world’s 105 largest cities. In Ecuador, 80 per cent of Quito’s 1.5 million residents get drinking water from two protected areas in the Andes; in the Dominican Republic, the Madre de las Aguas Conservation Area protects the source of 17 rivers that provide water for domestic use and irrigation for over half the country’s popu- lation (United Nations Environment Programme-WCMC and IUCN, 2016). Many protected areas need an integrated approach to multi-sectoral ecosystem management, both within coun- tries and where resources are shared among two or more countries with riparian rights to resources. An integrated approach can help to secure high-quality water supplies and address problems of scarcity and excess, which are likely to increase as populations increase and the climate changes. 3.

The main characteristics of non-point sources are that they respond to hydrological conditions, are not easily measured or controlled directly (and therefore are difficult to regulate) and focus on land and related management practices. Control of point sources in those countries having effective control programmes is carried out by effluent treatment ac- cording to regulations, usually under a system of discharge permits. In comparison, control of non-point sources, especially in agriculture, has been by education, promotion of appropriate management practices and modification of land use (Ongley, 1996). 147 drawals globally from renewable water resources which pollution loads.

Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation 150 Chapter IV. Beyond Sustainable Development Goal 6 An important option for making water savings is reducing food loss and waste (box 30). BOX 30 Reducing food loss and waste reduces agricultural water consumption One third of food produced for human consumption – equivalent to 1.3 billion tons and valued at US$1 trillion – is lost or wasted worldwide each year, mostly in the industrialized world (FAO, 2011b). Food is spoiled during harvest, storage and transporting, it is wasted along supply chains and also rots in the bins of consumers and retailers (FAO, n.d.b). This is contradictory to SDG 12, which promotes sustainable production and consumption. The global food loss index measures the total losses of agricultural commodities from production to retail and includes losses on farm, during transportation, in storage and during processing. Annual estimates of global food losses and waste are 30 per cent of cereals, 20 per cent of dairy products, 35 per cent of fish and seafood, 45 per cent of fruits and vegetables, 20 per cent of meat, 20 per cent of oilseeds and pulses, and 45 per cent of roots and tubers (FAO, 2015a). All the resources consumed to produce this food, including considerable amounts of water, are wasted. Notably, the carbon footprint of food waste was estimated at 3.3 billion tons of greenhouse gases, making food wastage the third-highest emitter of greenhouse gases (FAO, 2013b). Reducing losses and waste can significantly reduce water consumption on farms and along the food value chains. Water can then be released for more productive pur- poses instead, thus having a significant impact on food security, economies and the environment, especially water withdrawals. This links directly to sustainable consumption (SDG 12) and helps to decrease per capita food waste (target 12.3). A reduction in food losses could have an immediate and significant impact on the livelihoods of smallholder far- mers, where food is lost primarily due to infrastructure or capacity gaps, given that many such farmers in develo- ping countries live on the margins of food insecurity (FAO, 2011b; 2015b). 5.

UN Photo/Manuel Elias BOX 31 Degradation, armed conflict and displacement of people in the Lake Chad basin The Lake Chad region is one of the poorest areas in Africa, where poverty especially affects women. The riparian countries have high gender inequality rates where women have much lower access to education, information, agri- cultural extension services and credit. Lake Chad has rich biodiversity, and some 2 million people living on its banks and islands rely on the ecosystem services it provides, such as for fishing, agriculture and livestock farming. A further 50 million people live in the Lake Chad basin (Magrin and others, 2016). The basin has changed significantly over the past 30 years, due primarily to variations in rainfall and reduced flows into the lake, resulting from dam building on feeder rivers and irrigation development. Water levels have fallen, and the lake’s area shrunk by more than 90 per cent from 1963 to 1998a This has led to the loss of globally significant biodiversity and degraded ecosystems (IUCN, 2008). Erosion, desertification, deforestation and climate change have added to the basin’s vulnerability. Armed conflict has affected the area for many years, and an increase in terrorist activity has attracted mainly young, vulnerable people (non-educated, jobless and poor fringes of the population) (International Crisis Group, 2016). Mass displacement of people and their livestock has taken place due to the combined effects of ecosystem de- gradation, war and political crises. The decrease in natural resources has also generated recurring social conflicts, especially among farmers, herders and fishers. a The lake’s surface area was approximately 25,000 km² in 1963, but in 1985, it did not exceed 2,500 km² and reached less than 2,000 km² in the 2010s, according to the database on global natural resources by United Nations Environment Programme.

UN Photo/Kibae Park BOX 32 Water and peace Peace and development are inextricably linked. The Charter of the United Nations reflects this close connection with great clarity. Peace is more than the mere absence of war; it requires sustainable development. Development requires actors to cooperate and resolve their tensions without resorting to force. Any conflict limits development and prevents achievement of SDGs. This is regardless of whether the conflict is in the form of local tension, at the social or political level, or at the transboundary level. Competition over water can be a source of tension and a contributing factor to violent conflict. Water is seldom the only driver of conflict, but it is often among the important contributing factors. It is increasingly being used as a weapon of war in the armed conflicts of our era; water resources and installations are all too frequent objects of armed action. This is a practice that violates International Humanitarian Law. The Global High-Level Panel on Water and Peace analysed these problems and made some recommendations. These were addressed towards nations, the United Nations Security Council, and other United Nations entities, international bodies and non-State actors. The Panel also emphasized that water cooperation must be used as an instrument of peace. Reducing tensions and addressing important challenges around water is a necessity for reducing the risk of conflict. Water is a powerful tool for promoting cooperation. Water is vital and unique, and it has no substitute. It offers incentives for cooperation of all stakeholders. Transboundary water cooperation is an important example and de- monstrates a long history (in all regions of the world) of collaboration rather than conflict. These experiences create an important message. The more equitable an international water agreement, the more effective and stable cooperation becomes. Sharing benefits around water and creating river basin water user asso- ciations are incentives for cooperation and entry points for dialogue, peace and stability. The problem today is that there are too few such arrangements. Water cooperation is necessary at all levels: local, intersectoral, national, basin and international. Sharing water data and strengthening transparency is essential for success. Global monitoring of developments relating to water quantity and quality needs to be strengthened. Financial incentives for improved water cooperation must be imple- mented. Water diplomacy must be strengthened, as it represents a major contribution to maintaining international peace and security.

Several droughts drastically disrupted the local population in the region during the 1970s. Three countries bordering the Senegal River (Mali, Mauritania and Senegal) developed a close framework of cooperation through establishment of the Senegal River Basin Development Authority (Organisation pour la Mise en Valeur du fleuve Sénégal, OMVS) in 1972 (Convention concerning the Status of the Senegal River, 1972; Convention establi- shing OMVS, 1972). They were joined by Guinea in 2006. These four countries were the first African States to adopt specific legal instruments for joint work on an inter- national watercourse from 1978 (Convention concerning the Legal Status of Common Works, 1978; Convention regarding Financing Arrangements for Common Works, 1982). These instruments adopted under OMVS represent an example of cooperation in the use of shared water resource (Mbengue, 2013; 2014). OMVS was subsequently the driving force for the construction of the Diama and Manantali dams, completed in 1986 and 1988, respectively. These waterworks, which were subject to a common and indivisible ownership regime among the riparian States, play a significant role in strengthening cooperation in the Senegal River basin (Tignino and Sangbana, 2016). OMVS has managed to contain tensions among riparian States on several occasions. Incidents along the Senegal River border occurred between Senegal and Mauritania during the period 1989–1991. The escalation of violence was swift and caused many deaths on both sides of the border. Diplomatic relations between the two countries were cut off for two years. OMVS continued to function during this period, serving as the only communication framework between the two States. OMVS held a Council of Ministers meeting in Nouakchott, Mauritania, as soon as relations thawed and even before formal resumption of diplomatic relations. Diplomatic relations were then restored. This example illustrates the resilience of a basin organization to conflicts (even armed ones) that can break out among the riparian countries of an international river and the contribution that a solid framework of cooperation in the field of water can make for development and peace in a region.

Water-related disasters and climate change Climate change is expected to have significant impacts on freshwater systems and their management. Most effects will be experienced through changes in the hydrological cycle, such as overall water availability, water quality and frequen- cy of extreme weather events (e.g. floods and droughts). This cycle affects many water-using sectors including agriculture, energy, navigation, tourism and public health. Water-related hazards account for a significant amount of disaster loss and impact (figure 36). More than 1.6 million people died, and 5.5 billion people were affected by interna- tionally reported natural hazards between 1990 and 2015. Water-related hazards accounted for 62 per cent of deaths, 96 per cent of the people affected and 75 per cent of total damage costs amounting to US$2.5 trillion. For water-relat- ed hazards, mortality was mainly attributed to storms (45 per cent), tsunami (28 per cent), people affected by floods (54 per cent) and people affected by droughts (31 per cent).

BOX 35 Spotlight on water and cities: averting “Day Zero” in Cape Town, South Africa Cape Town is at the centre of international attention in 2018 due to an impending “Day Zero” – the day the water taps to the city will run dry. This drastic situation has arisen because of a prolonged three year drought, which has caused water storage levels in Cape Town’s nearby dams to be at unsustainably low levels. Cape Town is one of the world’s first major cities to face such severe drought and water supply conditions. Water managers have taken emergency steps to conserve water and to increase the effectiveness of piped delivery of wa- ter to households. Incentives such as water rationing, penalties for overuse and closing down illegal boreholes have been used to reduce household water use. The authorities are now planning steps to improve water governance by coordinating water allocations across those sectors that are heavy water consumers (e.g. agriculture and industry). The Cape region is a fruit-growing area that exports high-quality produce to Europe and other parts of Africa and is a key foreign exchange earner. It has had valuable orchards decimated by droughts and lack of water for irrigation. This is an example of how droughts are not just a local issue. The lack of produce for export affects many other countries across the world that have come to depend on fruit from this region. Limits and vulnerability arising from dependence on dam storage are evident. Local groundwater resources and de- salination facilities are options for additional drinking water.

A study by Business for Social Responsi- bility concluded that 60 per cent were using rags from the factory floor as menstrual cloths. These cloths were chemically charged and often freshly dyed, and so infections were common. This resulted in 73 per cent of women missing work for an average of six days a month. Women had no safe place to purchase cloth or pads or to change or dispose of them. The six days lost is a huge economic challenge to them, the employer and the supply chain, especially when women are paid by the garment. An intervention to change this reportedly saw absenteeism drop to 3 per cent, resulting in significant economic gains for the workers and the factory owner. Source: WWAP (2016). 3.

Most water-related courses tend to be in engineering faculties and so they provide a proxy for water-relat- ed education activities. Water also now features in other programmes such as environmental and social sciences, but it is difficult to determine the true extent. Full-time undergraduate engineering programmes in 2014/2015 represented 7.1 per cent (458,643) of the global student enrolment (6,417,881).

A total of 48,550 students graduated in civil, chemical, mechanical and environ- mental engineering, which were courses most likely to offer significant water-related curriculum. Thus, 43 per cent of engineering graduates could potentially work in the water sector (Yoder, 2016).

UN Photo/Martine Perret BOX 37 Risks to agricultural supply chains Water is an essential ingredient in products produced by global agrifood companies, the manufacturers and distri- butors of food and beverages. One of the most substantive water risks for companies in this sector lies within the agricultural supply chain. A CDP water survey in 2017 showed that agrifood companies identified supply chain disruption as a serious risk. Many are already experiencing severe financial losses due to water scarcity. A food conglomerate reported losing US$25 million due to two consecutive dry years in the Pongola–Umzimkulu River basin in South Africa. A large South African retail firm reported that drought and unprecedented heat in the Breede–Gourits River basin affected irrigation rights, which reduced crop yields and increased prices. Leading companies are beginning to invest to mitigate these risks by engaging with suppliers, public policymakers and other stakeholders in river basins. One multinational flavourings company expects the prices of raw materials to rise by 10–20 per cent in the South Pacific Basin, where severe dry conditions have affected growing conditions. The company has therefore set up support projects for farmers to teach them good agricultural practices, including im- proving irrigation techniques. The company has also partnered with drip irrigation providers to subsidize and supply farmers with modern irrigation systems to reduce water wastage. Sources: CDP (2017a; 2017b).

Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation 168 Chapter IV. Beyond Sustainable Development Goal 6 BOX 38 Virtual water trading in Latin America and the Caribbean Latin America and the Caribbean is a water-rich region, with 34 per cent of the world’s freshwater resources. Agri- culture accounted for 68 per cent of withdrawals in 2001 – 11 per cent for industrial use and 21 per cent for domes- tic use. Abundant water and available arable land led to significant growth as an exporter of agricultural commodi- ties to the world market. The growth in this sector improved the economic and social conditions of the region, while contributing to world food production. This then reduced the pressure on freshwater resources and food security in other countries. However, such development must be conducted in a sustainable manner, by considering the challenges present in the region. Latin America and the Caribbean is a net virtual water exporter comprising five major products: soybean (36 per cent), coffee (14 per cent), cotton (10 per cent), livestock products (10 per cent) and sugarcane (8 per cent), all mostly with a water footprint based on rain-fed agriculture using green water. The main importers are the United States (22 per cent), China (8 per cent), Germany (6 per cent), Netherlands (5 per cent), Italy (5 per cent), and Spain, France and Russian Federation (4 per cent each). The region also imports a significant amount of virtual water from the rest of the world: cotton products (42 per cent) (mainly from the United States and Pakistan), wheat (12 per cent) (mainly from the United States and Canada) and livestock products (11 per cent) (mainly from the United States). About 54 per cent of virtual water imports go to Mexico. The international virtual water flows within the region are small compared to exchanges with the rest of the world. Most of the virtual water flows are related to crop products (88 per cent). Those related to trade in animal and industrial products contribute 9 per cent and 3 per cent, respectively. The virtual water flows within the region are mostly green water (88 per cent), while blue and grey water contribute 5 per cent and 7 per cent, respectively. Net virtual water import related to imports of agricultural and industrial products from Latin America and the Caribbean (green) and countries with net virtual water export due to agricultural and industrial exports to Latin America and the Caribbean (red) over the period 1996–2005 (only the largest gross virtual water flows (>10 billion m3/year) are shown) Source: Mekonnen and others (2015). 169 5.

This was the first systemic linkage between water and financial informa- tion. CDP now holds the largest corporate water data set in the world and adds to it annually through its information request to companies, governments, cities, States and regions. Water is fundamental to industry, and both quality and quantity matter. Some 66 per cent of companies surveyed in 2017 considered sufficient amounts of good-quality freshwater to be “important” or “vital” for their operations. But companies recognize that water supply and quality is by no means guaranteed. Over 3,700 corporate water risks were reported in 2017, with a variety of physical, regulatory and reputational drivers. Top five water-related risk drivers and risks Sources: CDP (2017a; 2017b).

BOX 40 Food and beverage industry Water stewardship is becoming an increasingly important element of corporate sustainability. Many leading food and beverage corporations feature facets of water stewardship in their sustainability reports. Major companies acknowledge that physical and reputational water risks motivate their water stewardship goals. The companies are reliant on good water quality, for inclusion in the final product and for processing, cleaning, pasteurizing, cooling, diluting, brining, fermenting and more (Jones and others, 2015). Water-use analysis and benchmarking in one food and beverage company in Turkey were used to identify oppor- tunities for water conservation in the factory’s cooling systems. Water recycling and reuse were implemented. The cooling water demand dropped 92 per cent as a result, saving the company 503,893 m3 of water yearly and reducing the wastewater discharge by over 57 per cent. The payback period for these changes was seven months (Alkaya and Demirer, 2015). Coca-Cola has worked for many years to reduce water risk. It has identified one solution outside of its bottling factories: a goal to return water to communities and nature equal to the volume of their beverages. It replenished 221 billion litres or 133 per cent of the water used in its drinks in 2016. The methods included conducting a source water vulnerability assessment for each bottling plant and developing a source water protection plan to address issues by supporting specific community projects (The Coca-Cola Company, 2017).

Water withdrawals in the energy sector, 2014 Two thirds of global water withdrawals are from sur- face water and one third is from groundwater. Pumping groundwater is about seven times more energy intensive than surface water abstraction. But surface water usually requires much more (energy-intensive) treatment prior to use than groundwater (IEA, 2016a). One growing concern is the increasing use of groundwater for irrigation and the impact this will have on energy demand. Groundwater already supplies one third of the world’s irrigated area. This source is popular among the many millions of impoverished smallholder farmers across sub-Saharan Africa and South Asia because of easy ac- cess, reliability and flexibility (Shah, 2012). The demand for groundwater is likely to increase substantially, and so too will the energy needed for pumping, with few effective Source: IEA (2016a). controls in place.

BOX 41 Desalination There were approximately 18,000 desalination plants around the world in 2015, with a total installed production capa- city of 87 million m3/day. Some 44 per cent of this capacity (37 million m3/day) was in the Middle East (mainly Saudi Arabia, Kuwait, United Arab Emirates, Qatar and Bahrain) and North Africa (mainly Libya and Algeria). An expected US$10 billion investment in the next five years would add 5.7 million m3/day. The capacity is expected to double by 2030 (Voutchkov, 2016). Other countries using large desalination plants include Australia, Israel, Spain and United States. While desalination in the Middle East is projected to grow by 7–9 per cent annually, large desalination developments over the next decade are expected across Asia, United States and Latin America (FAO, 2016a; USGS, 2016; Voutchkov, 2016). Desalinated water is produced from brackish water (salt content less than 10,000 mg/l) and seawater with a salinity in the range 30,000–44,000 mg/l. Brackish water is limited in volume, and so most desalination will be from seawater, which is abundant. This offers a logical solution for sustainable, long-term management as water demand grows in arid regions (Voutchkov, 2016). However, desalination is costly and energy intensive, requiring significant investments in infrastructure. Technology advances can be expected to reduce the cost of desalinated water by 20 per cent in the next five years, and by up to 60 per cent in the next 20 years, making it a viable and cost-effective competitor for potable water production (USGS, 2016; Voutchkov, 2016). Desalination also has an environmental impact that must be understood and managed. Modern reverse-osmosis de- salination plants take in large volumes of seawater and discharge highly concentrated brine back into the sea. This is potentially harmful to fish and other marine organisms such as plankton, eggs and larvae. Brine has twice the salinity of seawater and it is much denser, so the two do not mix easily. The brine sinks and spreads along the ocean floor. There are methods for dispersing concentrated brine that involve diluting with wastewater and encouraging mixing, but further research is needed, especially to understand the long-term impact (Cooley and others, 2013).

Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation 176 Chapter IV. Beyond Sustainable Development Goal 6 BOX 42 Reducing water used to produce energy The 10 per cent of annual global water withdrawals for energy represents a large volume of water – 398 billion m3. A small saving in energy use or an increase in efficiency can make a big difference to water accessible for people. A saving of 1 per cent (4 billion m3) would provide enough water annually for 219 million people based on 50 litres per day as a basic access service level. This offers the prospect that solutions to water scarcity are within reach, especially if similar reductions are made in other water-using sectors such as agriculture and industry, although it is affected by location and many other factors.

In addition, governance and delivery systems are weak and fragmented. UN-Water’s Sustainable Development Goal 6 Synthesis Report 2018 on Water and Sanitation builds on the latest data available for the 11 SDG 6 global indicators. Representing a joint position from the United Nations family, the report offers guidance to understanding global progress on SDG 6 and its interdependencies with other goals and targets. It also provides insight into how countries can plan and act to ensure that no one is left behind when implementing the 2030 Agenda for Sustainable Development.
