Groundwater, which constitutes nearly 99% of all unfrozen fresh water on Earth, holds vast reserves below the feet of 400 million people in sub-Saharan Africa.
The use of solar-powered technology to access groundwater not only provides drinking water but also supports irrigation, addressing both water and food insecurity sustainably.
Recent advancements in mapping groundwater availability in Africa, paired with improved geological understanding, empower hydrogeologists to identify areas ideal for solar pumping installations.
At the International Association of Hydrogeologists' World Groundwater Congress, the focus is on how to effectively deploy affordable solar technology to exploit groundwater without depleting it.
