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.
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.
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).
The United Nations Office for Outer Space Affairs (UNOOSA), in collaboration with the Space Generation Advisory Council (SGAC), has launched the 2022 edition of the Space4Youth Essay Competition! Water scarcity is a major global challenge. Young people play a key role. UNOOSA and SGAC want to give a voice to and promote youth's ideas on the use of space for water resources management and aquatic ecosystem preservation.
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 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.

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.
