Background: Desertification is the degradation of land and soil in dryland ecosystems caused by both the climate and human activities. In the year 2000, one third of the population of the earth dwelled in dryland ecosystems, and drylands are 41% of world’s land. The effect of desertification is massive because of the amount of people that live in affected areas. Drylands facilitate 44% of the food production in the world and 50% of livestock, so these ecosystems are a very important source of resources. 2.6 billion people depend of the food developed in drylands and many of those people have jobs making the food. 52% of the land is being affected in some way by degradation because it removes the moisture that is needed to grow or herd food. Around 800 million people are going hungry and around 80% of these people are small land owners or they do not own any land and are very poor. This means that those small land owners might not have any land in the end because of the deterioration of healthy soil. Land degradation also effects water quantity and quality. Clean water is one of the most important resources in the world, and desertification eliminates that resource. 74% of those in poverty are directly affected by land degradation. 10-20% of drylands are degraded already. The places most effected by desertification are sub-Saharan and Central Asia drylands. Desertification occurs for various reasons. It can come from a failure to balance how much the ecosystem can give as
