Just about every cause of desertification is agriculturally-related. Fortunately, the cause of the problem is also its solution. Many organizations, including the United Nations, are already spreading the word that the answer to fighting desertification is sustainable agriculture. The U.N. Convention to Combat Desertification is all about promoting Sustainable Land Management. According to the Institute for Science in Society, recent research shows that using sustainable, traditional farming methods — such as fertilizing with manure, cover cropping with legumes, and integrating crops and livestock — farmers in some of the poorest African countries along the edge of the Sahara have actually been able to increase food production despite falling rainfall levels, keeping well ahead of population growth!
