European Space Agency’s “Water Scarcity” Kick-Start
Water is one of the most important substances on Earth and covers 70% of the planet. However, freshwater makes up a very small fraction with 97% being saline and ocean-based. While the amount of freshwater on the planet has remained fairly constant over time, the world’s population has exploded, meaning that freshwater is threatened by significant forces, like overdevelopment, polluted runoff, and global warming.

Call for local perspectives: Groundwater challenges
Local perspectives and case studies
The aim of the local perspectives and case studies feature is to learn about gaps in water resource management from affected individuals, communities, civil society, professionals, researchers or organisations in the field to identify needs or potential solutions that space technologies could contribute to.
Can space technologies help improve WASH provision in camps and informal settlements?
The Human Right to water and sanitation
What does your morning routine look like? For most readers I’d assume you use the toilet, wash your hands, and maybe take a shower. However, do you ever stop to consider the water you use to shower, or the soap you use to wash your hands? Often, especially in developed countries, these things are taken for granted, rightly considering access to adequate water, sanitation, and hygiene (WASH) as basic Human Rights (Figure 1).
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.

Global Precipitation Mission: Improved, accurate and timely global precipitation information
Continuous and reliable global precipitation information is crucial for myriad of weather, climate and hydrological applications. The importance of precipitation in the form of rain, hail, sleet, snow etc. is known to science and clear to a layman. However, it’s quite tricky to measure past precipitation trends or predicting accurate future forecasts. There are three main categories of precipitation data sets available: ground based, satellite-based and blended products of ground and space data (Climate Data Guide, 2014).
DeepWaters AI uses satellite data and AI to find underground drinking water and pipe leaks. It has created a map of the Earth’s underground water, with up to 98% accuracy. It was awarded a European Space Agency AI Kickstart contract in 2018. DeepWaters AI is supported by Esri, Amazon and Nvidia startup programs. It is a UK based social impact startup, that donates 51% of profits to water philanthropy. DeepWaters AI combines neural networks with ESA Sentinel 1 & 2 satellite data.
International Groundwater Resources Assessment Centre
The International Groundwater Resources Assessment Centre (IGRAC) facilitates and promotes international sharing of information and knowledge required for sustainable groundwater resources development and management worldwide. Since 2003, IGRAC provides an independent content and process support, focusing particularly on trans-boundary aquifer assessment and groundwater monitoring.
Rural Water Supply Network Stakeholder
Rural Water Supply Network
The Rural Water Supply Network (RWSN) is the global network for rural water supply professionals, with 11,000 members in more than 150 countries. RWSN is a strategic global platform for knowledge sharing and collaboration in the water sector with a central focus on the achievement of universal access to safe, affordable water supplies.
The role of groundwater in advancing Africa’s socio-economic development
The African Ministers Council on Water (AMCOW) is hosting a webinar that will discuss the significance and contribution of groundwater to water security including domestic supply for drinking and sanitation, agricultural and industrial productions as well as ecosystem services in Africa.
The webinar will feature expert presentations and panel discussions among groundwater experts from the private sector, CSOs, academia and research institutions both within and outside Africa.
Groundwater Summit Event
In 2022, the international World Water Day (WWD) will be dedicated to groundwater. As usual, the World Water Development Report (WWDR) for that year will be about the same topic: groundwater. Groundwater Summit is envisaged as a central celebration of the WWD, and the venue for launching the WWDR.

Groundwater makes up roughly 30% of global freshwater. It also provides drinking water for the world’s population, and irrigation for close to 1/3rd of global agricultural land. Because of this level of reliance, monitoring groundwater is crucial for water resources and land management. The Gravity Recovery and Climate Experiment (GRACE) and GRACE-Follow On (GRACE-FO) missions from NASA and the German Research Centre for Geosciences (GFZ) provide large-scale terrestrial water storage estimation from mid-2000 to present.

Groundwater is an essential factor for ecosystems and humanity alike. It ensures ecosystem stability, energy and food security, and promotes human health. Groundwater is the largest component of global liquid freshwater resources in the water cycle, providing about 30% of the total freshwater. Groundwater accounts for 33% of the global water withdrawals by mankind, with more than two billion people depending on groundwater as primary water resource. However, despite its importance, groundwater is often not included in sustainable water management actions and plans.
