Over the next 25 years, nearly one in two Africans will live in countries stressed by fresh water shortages and the main conflicts in Africa could be over water supplies, according to a U.N. Development Program report. One-fourth of the world’s populace will suffer severe water scarcity during the same time period, even during years of average rainfall, according to the U.N.-affiliated Consultative Group on International Agricultural Research. CGIAR has launched a new Internet project that will allow citizens throughout the world to access free, detailed data about fresh water in their regions and the suitability of their land for certain types of agriculture, compiled by the International Water Management Institute.
