In the Sahel, a semi-arid region that is heavily dependent on water resources for agricultural output, solar-powered irrigation has a great deal of promise, according to a recent article from the Food and Agriculture Organization of the United Nations (FAO). In a area that is often affected by drought and hunger, the study Solar Irrigation Potential in the Sahel highlights the potential to tap into massive groundwater supplies, which may significantly boost agricultural productivity and food security. According to the most recent estimate, over 38 million people in the Sahel and West Africa are either in a food insecurity crisis or at a severe level.
