“In the deserts and dryland communities of the Sahel region, the scarcity of water resources threatens livelihoods, agriculture, and even industries. And due to the limited number of rivers and lakes to draw water from, groundwater is the region’s main source of water. Therefore, increasing the sustainable development of more groundwater, the water that is present beneath the Earth’s surface in rock and soil pore spaces, will be key to provide water security and socioeconomic benefits to this region that is home to more than 135 million people.”
