Ensure availability and sustainable management of water and sanitation for all

None of the SDG 6 targets are on track to be met. As of 2022, 2.2 billion people were without access to safely managed drinking water and 3.5 billion lacked access to safely managed sanitation. Between 2002 and 2021 droughts affected more than 1.4 billion people. As of 2022, roughly half of the world’s population experienced severe water scarcity for at least part of the year, while one quarter faced ‘extremely high’ levels of water stress. Climate change worsens these issues, posing significant risks to social stability. While transboundary river and lake basins are home to approximately 40% of the world’s population and are shared by 153 countries, less than a fifth of these countries have operational arrangements for cooperation in place for all their transboundary waters. Coordinated global action on integrated water management, addressing the impacts of climate change on water resources, and better management of shared waters are key to restoring focus on the Goal.

Targets 6.1 and 6.2: Between 2015 and 2022, the population using safely managed drinking water increased from 69% to 73%, the population using safely managed sanitation increased from 49% to 57% and the population using basic hygiene services increased from 67% to 75%. Achieving universal coverage of safely managed drinking water, safely managed sanitation, and basic hygiene services by 2030 will require respective increases of 6x, 5x, and 3x in the current global rates of progress.

Target 6.3: Among the 73 countries reporting on both total wastewater generation and total wastewater treatment in 2022, 76% of total wastewater flows received at least some treatment. Of the 42 countries that specified the level of treatment, 60% of total wastewater flows were safely treated (i.e. at least secondary treatment). In all world regions, many rivers, lakes and aquifers are still in good condition – as of 2023, 56% of water bodies assessed in 120 countries have good water quality. However, countries that implement the most extensive monitoring programmes show that water quality is degrading since 2017.

Target 6.4: Water use efficiency rose from $17.4/m3 in 2015 to $20.8/m3 in 2021, a 19% increase. At the global level, the water stress level reached an average level of 18.6% in 2021 but it hides large regional variations as some regions in the world show critical water stress levels which may compromise their economic and social development. Globally, water stress level has slightly increased by 3% from 2015 to 2021.

Target 6.5: Global progress on implementing integrated water resources management remains slow – 49% in 2017, 54% in 2020, 57% in 2023, not on track to reach the 2030 target (91%). Only 43 out of 153 countries have operational arrangements in place for 90% or more of their shared transboundary waters (rivers, lakes and aquifers), and more than 20 countries have no operational arrangements in place for any of their transboundary waters. Since 2020 only around ten new arrangements for transboundary water cooperation have been adopted.

Target 6.6: The world has experienced a net increase in permanent surface water between 2005 and 2022, much of which resulted from climate change and reservoir filling. While this global net gain is positive, it is important to recognize that the data also include losses of permanent water in some regions linked to droughts and increased water demands.

Target 6.a: ODA disbursements to the water sector increased between 2021 and 2022 by 10% to $8.5 billion, reversing a declining trend seen over the past five years.

Billions of people still lack access to safe water, sanitation, and hygiene, despite improvement in the provision of these basic services. Water scarcity is a growing problem in many parts of the world, and conflicts and climate change are exacerbating the issue. In addition, water pollution is a significant challenge which affects both human health and the environment in many countries. Achieving universal coverage by 2030 will require a 6-fold increase in current global rates of progress on drinking water, a 5-fold increase for sanitation, and an 8-fold increase for hygiene. Boosting infrastructure investment, improving cross-sectoral coordination, and addressing climate change is key to getting SDG6 back on track.

Targets 6.1 and 6.2: Despite progress, 2.2 billion people still lacked safely managed drinking water services, 3.4 billion lacked safely managed sanitation services, and 1.9 billion lacked basic hygiene services in 2022. While the majority live in rural areas, the unserved population is decreasing in rural areas and stagnating or increasing in urban areas. Achieving universal coverage by 2030 will require an increase of 5 to 8 times the current rate.

Target 6.3: An estimated 58% of wastewater generated by households was safely treated in 2022, based on data from 140 countries and territories. Trends for domestic wastewater suggest that little, if any, progress is being made towards the target of halving the proportion of unsafe discharges by 2030.

Target 6.4: Water use efficiency rose from $17.4/m3 in 2015 to $18.9/m3 worldwide in 2020, which represents a 9% efficiency increase. Around 57% of countries presented a water use efficiency equivalent to $20/m3 or less in 2020, compared to 58% in 2015.

Target 6.4: At the global level, water stress remains at a safe level of 18.2% in 2020, but this figure masks vast regional variations and indicates a 1.2% increase from 2015 to 2020. In 2020, water stress levels ranged from high in Southern Asia and Central Asia to critical in Northern Africa. The situation in Western Asia and Northern Africa is particularly concerning since it registered an 18% increase in water stress levels from 2015 to 2020.

Target 6.5: One in two countries still lacks effective frameworks for sustainable water management. A lack of cross-sector coordination over water use, between agriculture, industry, energy production, and household supply, threatens the achievement of several SDGs, including those on food, energy, and life on land. While progress has been made globally since 2015—from 49/100 in 2017 to 54/100 in 2020—the rate of implementation needs to double to achieve the target.

Target 6.5: Data from 2017 and 2020 show that only 32 out of 153 countries that share transboundary rivers, lakes, and aquifers have 90% or more of those waters covered by operational arrangements.

Target 6.6: The extent of surface water bodies, including lakes, rivers, and reservoirs, is rapidly changing across the entire planet, with one in five river basins experiencing high (i.e. above natural) fluctuations in surface water during the last 5 years.

Target 6.a: ODA disbursements to the water sector decreased between 2015 and 2021 from $9.1 billion to $7.8 billion, a decrease of 15%. Total ODA commitments to the water sector have also reduced by 13% from $10.8 billion in 2015 to $9.4 billion in 2021. Commitments peaked at $13 billion in 2017 and have decreased every year since.

Target 6.b: Since 2016, the percentage of countries having procedures for local community participation defined in law or policy has remained high (over 70%) for both rural drinking water and for water resources management. However, the percentage of countries with high levels of participation remains consistently low (under 40%).

Access to safe water, sanitation and hygiene is the most basic human need for health and well-being. Billions of people will lack access to these basic services in 2030 unless progress quadruples. Demand for water is rising owing to rapid population growth, urbanization and increasing water needs from agriculture, industry, and energy sectors. Decades of misuse, poor management, overextraction of groundwater and contamination of freshwater supplies have exacerbated water stress. In addition, countries are facing growing challenges linked to degraded water-related ecosystems, water scarcity caused by climate change, underinvestment in water and sanitation and insufficient cooperation on transboundary waters.

Between 2015 and 2020, the population using safely managed drinking water services increased from 70 per cent to 74 per cent, the population with safely managed sanitation increased from 47 per cent to 54 per cent and the population with access to handwashing facilities with soap and water in the home increased from 67 per cent to 71 per cent. Rates of progress for these basic services would need to quadruple for universal coverage to be reached by 2030. 

Assessment of rivers, lakes and aquifers in 97 countries in 2020 shows that 60 per cent of water bodies assessed have good water quality. Of the 76,000 water bodies that were reported on in 2020, only 1 per cent were from the poorest countries. For at least 3 billion people, the quality of the water they rely upon is unknown owing to a lack of monitoring.

Water use efficiency worldwide rose from $17.4 per cubic metre in 2015 to $19.4 per cubic metre in 2019, which represents a 12 per cent efficiency increase. Around 57 per cent of countries presented a water use efficiency equivalent to $20 per cubic metre or less in 2019.

Across the world, water stress levels remained safe at 18.6 per cent in 2019, although this hides large regional variations. Southern Asia and Central Asia registered high levels of water stress at over 75 per cent, whereas Northern Africa registered a critical water stress level of over 100 per cent. Since 2015, water stress levels have increased significantly in Western Asia and Northern Africa.

To ensure a sustainable and equitable distribution of water to meet domestic, industrial, agricultural and environmental needs, the average global rate of implementation of improved management of water resources – from 49 in 2017 to 54 in 2020 – needs urgently to double. With political will and adequate financing, 22 countries made significant gains between 2017 and 2020, showing that real and rapid progress is possible and providing tangible examples for the 107 countries that need to significantly accelerate implementation.

Transboundary rivers, lakes and aquifers are shared by 153 countries around the world. Ensuring that these waters are managed equitably, sustainably, and peacefully, particularly in the context of climate change, requires countries to put in place operational arrangements for water cooperation. Data from 2017 and 2020 suggest slow progress, with only 32 countries having 90 per cent or more of their transboundary waters covered by such arrangements. 

Over the past 300 years, wetland ecosystems have experienced an 85 per cent loss in extent despite the very high value goods and services that they provide. Additionally, the extent of surface water bodies, including lakes, rivers, and reservoirs, is rapidly changing across the entire planet, with one in five river basins experiencing high - above natural - fluctuations in surface water during the last five years. Population growth, changes to land cover and land use and climate change are key drivers of these changes to freshwater ecosystems.

Billions of people worldwide still live without safely managed drinking-water, sanitation and hygiene services, which are critical for protecting human health and containing the spread of the COVID-19 virus. Over the past century, global water use has increased at more than twice the rate of population growth. In addition to water stress, countries and territories are facing growing challenges linked to water pollution, degraded water-related ecosystems, water scarcity caused by climate change, and a lack of cooperation on transboundary waters. The world is not on track to achieve Goal 6. A dramatic acceleration is needed in the current rates of progress and in integrated and holistic approaches to water management.

Between 2000 and 2020, the global population using safely managed drinkingwater and sanitation services increased by 2 billion and 2.4 billion, respectively. Despite the progress, 2 billion people lacked safely managed drinking-water services, 3.6 billion safely managed sanitation services and 2.3 billion basic hygiene services in 2020. One in three people worldwide still lack basic handwashing facilities with soap and water at home, leaving them especially vulnerable to the COVID-19 virus.

Among the 42 countries and territories reporting on total wastewater generation and treatment in 2015, 32 per cent of wastewater flows were subject to some form of treatment. An estimated 56 per cent of wastewater generated by households in 2020 was safely treated, according to data from 128 countries and territories.

An assessment of rivers, lakes and aquifers of 89 countries and territories in 2020 indicates that the water quality of 72 per cent of the water bodies assessed is good. Protection is easier than restoration, so efforts to protect these water bodies from pollution must be initiated now.

Improving water use efficiency is a key measure that can contribute to reducing water stress in a country. Global efficiency increased from $17.30 per m3 in 2015 to $19 per m3 in 2018, a 10 per cent increase. All economic sectors have experienced an increase in water use efficiency since 2015, with increases of 15 per cent in the industrial sector, 8 per cent in the agricultural sector and 8 per cent in the services sector.

In 2018, global water stress was estimated to be 18.4 per cent, an increase from 18.2 per cent in 2015. Regions such as Western and Southern Asia and Northern Africa present very high levels of water stress at more than 70 per cent, while SouthEastern Asia, Latin America and the Caribbean, and sub-Saharan Africa saw their water stress levels increase from 2017 to 2018.

In 2020, 129 countries and territories were not on track to meet the target for implementing integrated water resources management by 2030, which includes financing and intersectoral coordination mechanisms, basin management and monitoring. The rate of implementation needs to double globally. In many countries and territories, the COVID-19 pandemic has led to wider stakeholder engagement in water resources management through online consultations.

Advancing transboundary water cooperation plays a crucial role in preventing conflicts and supporting wider regional integration, peace and sustainable development. However, according to data from 2017 and 2020, only 24 of the 153 countries and territories that share transboundary rivers, lakes and aquifers have 100 per cent of their transboundary basin area covered by operational arrangements, and only another 22 countries and territories have more than 70 per cent covered.

Freshwater ecosystems and the multitude of resources that they provide are changing dramatically. One fifth of the world’s river basins are experiencing rapid increases or decreases in surface water area. This unprecedented situation is compounded by pollution in large lakes and the persistent loss and degradation of wetlands and freshwater biodiversity. Between 1970 and 2015, the total area of inland and marine or coastal wetlands declined by approximately 35 per cent, three times the rate of forest loss. Existing efforts to protect and restore water-related ecosystems must be scaled up and accelerated urgently.

From 2015 to 2019, ODA disbursements to the water sector remained stable at around $8.8 billion, while ODA commitments to the water sector rose by 9 per cent. In the same period, concessional lending for the least developed countries increased by 52 per cent to $2 billion, with ODA grants to those countries increasing by only 8 per cent.

In 2018 and 2019, two thirds of the 109 reporting countries and territories had procedures for the participation of local communities in water and sanitation management that were defined in laws or policies. However, only 14 countries and territories reported high levels of community and user participation in collaborative management and decision-making.

Billions of people throughout the world still lack access to safely managed water and sanitation services and basic handwashing facilities at home, which are critical to preventing spreading the spread of COVID-19. Immediate action to improve Water, Sanitation and Hygiene for All (WASH) is critical to preventing infection and containing its spread.

In 2017, only 71 per cent of the global population used safely managed drinking water and just 45 per cent used safely managed sanitation services, leaving 2.2 billion persons without safely managed drinking water, including 785 million without even basic drinking water, and 4.2 billion without safely managed sanitation. Of those, 673 million persons still practised open defecation.

In 2016, one in four health-care facilities throughout the world lacked basic water services, and one in five had no sanitation services.

In 2017, 3 billion persons lacked soap and water at home. In 2016, 47 per cent of schools worldwide lacked handwashing facilities with available soap and water, and 40 per cent of health-care facilities were not equipped to practise hand hygiene at points of care.

Preliminary estimates from 79 mostly high- and higher-middle income countries in 2019 suggest that, in about one quarter of the countries, less than half of all household wastewater flows were treated safely.

In 2017, Central and Southern Asia and Northern Africa registered very high water stress – defined as the ratio of fresh water withdrawn to total renewable freshwater resources – of more than 70 per cent, followed by Western Asia and Eastern Asia, with high water stress of 54 per cent and 46 per cent, respectively.

In 2018, 60 per cent of 172 countries reported very low, low and medium-low levels of implementation of integrated water resources management and were unlikely to meet the implementation target by 2030.

According to data from 67 countries, the average percentage of national transboundary basins covered by an operational arrangement was 59 per cent in the period 2017–2018. Only 17 countries reported that all of their transboundary basins were covered by such arrangements. ·

Globally, in 2018, slightly more than 2.1 per cent of land was covered by freshwater bodies, although unevenly distributed, ranging from 3.5 per cent in developed countries to only 1.4 per cent in developing countries and 1.2 per cent and 1 per cent in least developed countries and small island developing States, respectively. The adverse effects of climate change can decrease the extent of freshwater bodies, thereby worsening ecosystems and livelihoods.

ODA disbursements to the water sector increased to $9 billion, or 6 per cent, in 2018, following a decrease in such disbursements in 2017. However, ODA commitments fell by 9 per cent in 2018. Because countries have signalled a funding gap of 61 per cent between what is needed to achieve national drinking water and sanitation targets and available funding, increasing donor commitments to the water sector will remain crucial to make progress towards Goal 6.

Despite progress, billions of people still lack safe water, sanitation and handwashing facilities. Data suggests that achieving universal access to even basic sanitation service by 2030 would require doubling the current annual rate of progress. More efficient use and management of water are critical to addressing the growing demand for water, threats to water security and the increasing frequency and severity of droughts and floods resulting from climate change. As of the time of writing, most countries are unlikely to reach full implementation of integrated water resources management by 2030.

• Globally, the proportion of population using safely managed drinking water services increased from 61 to 71 per cent between 2000 and 2015 and remained unchanged in 2017. An additional 19 per cent of the global population used basic drinking water services. This means that 785 million people still lacked even a basic drinking water service.
• The global population using safely managed sanitation services increased from 28 per cent in 2000 to 43 per cent in 2015 and to 45 per cent in 2017, with the greatest increases occurring in Latin America and the Caribbean, sub-Saharan Africa and East and South-East Asia. Between 2000 and 2017, the proportion lacking even a basic sanitation service decreased from 44 to 27 per cent, yet 701 million people still practiced open defecation in 2017. E/2019/68 19-07404 13/39
• In 2017, some 60 per cent of people worldwide and only 38 per cent in least developed countries had a basic handwashing facility with soap and water at home, leaving an estimated 3 billion people without basic handwashing facilities at home.
• In 2016, one third of all primary schools lacked basic drinking water, sanitation and hygiene services, affecting the education of millions of schoolchildren, but particularly girls managing menstruation, and one in four health-care facilities worldwide lacked basic water services, affecting more than 2 billion people.
• Approximately one third of countries have medium or high levels of water stress. Almost all countries that have registered high water stress are located in North Africa and West Asia or in Central and South Asia, and these levels indicate serious water difficulties in the supply of freshwater, at least during parts of the year.
• Of 172 countries, 80 per cent have medium-low implementation or better of integrated water resources management. However, 60 per cent of countries are unlikely to reach the target of full implementation by 2030.
• A significant effort is needed to ensure that cooperation is operational in all transboundary basins. According to data from 67 of 153 countries that share transboundary waters, the average percentage of national transboundary basins covered by an operational arrangement was 59 per cent in the period 2017–2018, with only 17 countries reporting that all their transboundary basins were covered by such arrangements.
• Following several years of steady increases and after reaching $9 billion in 2016, ODA disbursements to the water sector declined by 2 per cent from 2016 to 2017. However, ODA commitments to the water sector jumped by 36 per cent between 2016 and 2017, indicating a renewed focus by donors on the sector.

Too many people still lack access to safely managed water supplies and sanitation facilities. Water scarcity, flooding and lack of proper wastewater management also hinder social and economic development. Increasing water efficiency and improving water management are critical to balancing the competing and growing water demands from various sectors and users.

• In 2015, 29 per cent of the global population lacked safely managed drinking water supplies, and 61 per cent were without safely managed sanitation services. In 2015, 892 million people continued to practise open defecation.
• In 2015, only 27 per cent of the population in LDCs had basic handwashing facilities.
• Preliminary estimates from household data of 79 mostly high- and high-middle-income countries (excluding much of Africa and Asia) suggest that 59 per cent of all domestic wastewater is safely treated.
• In 22 countries, mostly in the Northern Africa and Western Asia region and in the Central and Southern Asia region, the water stress level is above 70 per cent, indicating the strong probability of future water scarcity.
• In 2017–2018, 157 countries reported average implementation of integrated water resources management of 48 per cent.
• Based on data from 62 out of 153 countries sharing transboundary waters, the average percentage of national transboundary basins covered by an operational arrangement was only 59 per cent in 2017.

Access to safe water and sanitation and sound management of freshwater ecosystems are essential to human health and to environmental sustainability and economic prosperity.

• In 2015, 6.6 billion people (over 90 per cent of the world’s population) used improved drinking water sources and 4.9 billion people (over two thirds of the world’s population) used improved sanitation facilities. In both cases, people without access live predominantly in rural areas. Achieving universal access to basic sanitation and ending the unsafe practice of open defecation will require substantial acceleration of progress in rural areas of Central and Southern Asia, Eastern and South-Eastern Asia and sub-Saharan Africa.
• Effective water and sanitation management relies on the participation of a range of stakeholders, including local communities. A 2016-2017 survey found that over 80 per cent of 74 responding countries had clearly defined procedures for engaging service users/communities in water and sanitation management.
• More than 2 billion people globally are living in countries with excess water stress, defined as the ratio of total freshwater withdrawn to total renewable freshwater resources above a threshold of 25 per cent. Northern Africa and Western Asia experience water stress levels above 60 per cent, which indicates the strong probability of future water scarcity.
• In 2012, 65 per cent of the 130 countries that responded to a survey on integrated water resources management reported that management plans were in place at the national level.
• ODA for the water sector has been rising steadily, but has remained relatively constant as a proportion of total ODA disbursements, at approximately 5 per cent since 2005. In 2015, ODA disbursements in the water sector totalled about $8.6 billion, which represents an increase of 67 per cent in real terms since 2005.

• Water and sanitation are at the very core of sustainable development, critical to the survival of people and the planet. Goal 6 not only addresses the issues relating to drinking water, sanitation and hygiene, but also the quality and sustainability of water resources worldwide.
• In 2015, 4.9 billion people globally used an improved sanitation facility; 2.4 billion did not. Among those lacking adequate sanitation were 946 million people without any facilities at all, who continued to practise open defecation. In 2015, 68 per cent of the global population was using improved sanitation facilities compared to 59 per cent in 2000. Nevertheless, the unsafe management of faecal waste and wastewater continues to present a major risk to public health and the environment.
• More progress has been made in access to drinking water. In 2015, 6.6 billion people, or 91 per cent of the global population, used an improved drinking water source, versus 82 per cent in 2000. Despite that improvement, an estimated 663 million people were using unimproved water sources or surface water that year. While coverage was around 90 per cent or more in all regions except sub-Saharan Africa and Oceania, widespread inequalities persist within and among countries. Moreover, not all improved sources are safe. For instance, in 2012 it was estimated that at least 1.8 billion people were exposed to drinking water sources contaminated with faecal matter.
• Holistic management of the water cycle means taking into account the level of “water stress”, calculated as the ratio of total fresh water withdrawn by all major sectors to the total renewable fresh water resources in a particular country or region. Currently, water stress affects more than 2 billion people around the world, a figure that is projected to rise. Already, water stress affects countries on every continent and hinders the sustainability of natural resources, as well as economic and social development. In 2011, 41 countries experienced water stress, an increase from 36 countries in 1998. Of those, 10 countries, on the Arabian Peninsula, in Central Asia and in Northern Africa, withdrew more than 100 per cent of their renewable fresh water resources.
• Integrated water resources management, one of the follow-up actions to the Plan of Implementation of the World Summit on Sustainable Development (Johannesburg Plan of Implementation), aims to address this urgent situation. In 2012, 65 per cent of the 130 countries that responded to a survey question on integrated water resources management reported that management plans were in place at the national level.
• Total official flows for water and sanitation were $10 billion in 2014, of which total aid flows from DAC donors amounted to $8 billion. Aid for water and sanitation nearly doubled as a share of ODA during the International Drinking Water Supply and Sanitation Decade (1981-1990). Since that time, on average, it has remained at around 7 per cent of total aid flows. Better targeting and tracking of water aid within the context of national situations is needed. For instance, numerous countries with limited access to water supply and/or sanitation have been receiving minimal external assistance (typically less than $2 per capita annually), while other countries with higher levels of access have received much more (at least $30 per capita a year).
• Effective water and sanitation management also depends on the participation of stakeholders. According to a 2013-2014 Global Analysis and Assessment of Sanitation and Drinking-Water survey, 83 per cent of the 94 countries surveyed reported that procedures for stakeholder participation were clearly defined in law or policy. In the Sustainable Development Goals, the focus is being refined to also include the participation of local communities, which will be captured in the next cycle of Global Analysis and Assessment of Sanitation and Drinking-Water monitoring.
