SDG 6 - Clean water and sanitation
Ensure access to water and sanitation for all
Clean, accessible water for all is an essential part of the world we want to live in. There is sufficient fresh water on the planet to achieve this. But due to bad economics or poor infrastructure, every year millions of people, most of them children, die from diseases associated with inadequate water supply, sanitation and hygiene.
Water scarcity, poor water quality and inadequate sanitation negatively impact food security, livelihood choices and educational opportunities for poor families across the world. Drought afflicts some of the world’s poorest countries, worsening hunger and malnutrition.
By 2050, at least one in four people is likely to live in a country affected by chronic or recurring shortages of fresh water.
Facts and Figures
- 2.6 billion people have gained access to improved drinking water sources since 1990, but 663 million people are still without
- At least 1.8 billion people globally use a source of drinking water that is fecally contaminated
- Between 1990 and 2015, the proportion of the global population using an improved drinking water source has increased from 76 per cent to 91 per cent
- But water scarcity affects more than 40 per cent of the global population and is projected to rise. Over 1.7 billion people are currently living in river basins where water use exceeds recharge
- 2.4 billion people lack access to basic sanitation services, such as toilets or latrines
- More than 80 per cent of wastewater resulting from human activities is discharged into rivers or sea without any pollution removal
- Each day,nearly 1,000 children die due to preventable water and sanitation-related diarrhoeal diseases
- Hydropower is the most important and widely-used renewable source of energy and as of 2011, represented 16 per cent of total electricity production worldwide
- Approximately 70 per cent of all water abstracted from rivers, lakes and aquifers is used for irrigation
- Floods and other water-related disasters account for 70 per cent of all deaths related to natural disasters
Space-based technologies for SDG 6
Water conservation and management are among the most critical issues facing humankind.Space technology can help analyse global water cycles, map water courses, and monitor and mitigate the effects of floods and droughts. Since 2008, UNOOSA, together with the Prince Sultan bin Abdulaziz International Prize for Water, organizes conferences on the use of space technology for water management and this web portal is among the results of this cooperation.
Moreover, the International Water Management Institute (IWMI) is one of the Regional Support Offices of UN-SPIDER. Read more here.

Les réserves mondiales d'eau souterraine
Les eaux souterraines représentent 30 % des ressources en eau douce de la planète (Shiklomanov 1993) (figure 1) et fournissent au niveau mondial 36 % de l'eau potable, 42 % de l'eau d'irrigation et 24 % de l'eau industrielle, témoignant de leur valeur considérable (Global Environment Facility 2021).
A hidden secret that becomes water: Monitoring Patagonian Glacier Retreat
It was not long ago, in 1916, that the explorer Padre De Agostini surveyed part of the topography of the Escondidos glaciers (“hidden glaciers”, in English) in Patagonia (De Agostini, 1949). Today, space technology such as NASA’s ICESat Missions and Shuttle Radar Topography Mission (SRTM) data, allow to monitor changes in glaciers over time.

Space-based technologies and data complementing GRACE datasets for groundwater assessments and monitoring
With increasing populations, groundwater abstraction also increased as about half of the global urban population access their water through aquifers (Foster et al., 2020). With 74% of the world population depending on it for safe drinking water services and sanitation (WHO and UNICEF, 2021), groundwater plays a vital role in health.

Real-time drought monitoring from Climate Hazards group Infrared Precipitation with Stations (CHIRPS)
Different parts of world are experiencing extreme hydrological hazards such as droughts, flooding and other related events. Droughts are associated with absence of rainfall occurrence over an extended period. According to the United Nations (2022), the frequency and intensity of drought events in the last two decades has increased by 29%. These figures are expected to increase further in the coming years due to climate change (Gunathilake et al., 2020).
Exploring the exciting potential of hyperspectral imaging for water quality monitoring
Harmful Algal Blooms occur when toxin-producing algae experience excessive growth within bodies of water. These blooms have the potential to cause detrimental effects on both aquatic and human health and can sometimes even cause death, depending on the type of algae involved (NIEHS, 2021). Thanks to the use of space-based remote sensing technology to monitor water quality conditions in coastal areas and drinking water reservoirs, nations are becoming more aware of the quality of their water.
Wetlands conservation: How satellite observation supports sustainable wetland management

Space technologies in the detection, monitoring and management of groundwater
Global groundwater supplies
Groundwater accounts for 30% of Earth’s freshwater resources (Shiklomanov 1993) (Figure 1) and is estimated to globally provide 36% of potable water, 42% of irrigation water, and 24% of industrial water – indicating its significant value (Global Environment Facility 2021). Groundwater affords a host of benefits, from providing better protection against drought and microbiological contamination than surface waters, to being generally low cost and accessible to many users.

Rapid Impact Assessment Using Open-source Earth Observation - on the example of the Kachowka Dam Break
The Jupyter notebook demonstrates how EOdal can be used for disaster relief after the break of the Kachowka using open-source Earth Observation data.
On June 6, 2023, the Kakhovka Dam in Ukraine broke. We do not yet know who or what was responsible for the collapse of the dam. What we do know, however, are the devastating consequences for the region downstream - especially for the local population.

In October 2021, the UN Human Rights Council recognized a safe, clean, healthy, and sustainable environment (R2HE) as a human right. The Council’s adoption of Resolution 48/13 is an important tool to address water resources degradation and overuse. Water is most often the medium through which climate change effects are experienced, especially by poor and vulnerable communities.
Participatory workshop for indigenous women on their roles and responsibilities related to water
register here until 21 August 2022 - if you would like to be considered for funding
In many places around the world women are responsible for water collection, a responsibility that globally takes them 200 million hours annually. It often leaves them with little to no time for school, work or to spend time with their family. Furthermore, indigenous communities' cultural heritage and knowledge about natural resources, including water, urgently needs to be considered and protected.
