Map shows groundwater irrigation potential in Africa


Today (June 17) marks the UN’s World Day to Combat Desertification. This year’s theme – attainment of food security for all through sustainable food systems – cannot be achieved without smart water management. This is where a new map from the International Water Management Institute (IWMI) can help.

Highlighted in a recent journal article, the map provides an in-depth look at groundwater irrigation potential in Africa. The map was developed using four decades of groundwater data along with crop information from the beginning of the century. It predicts groundwater availability for irrigation after other human needs are met, and is based on three scenarios with 30%, 50% and 70% of groundwater supplies left to sustain a healthy water flow and other environmental requirements.
