38 Percent of World’s Land in Danger of Turning into Desert
By Brian Merchant/TreeHugger

If you’re not familiar with desertification, it might be time to get acquainted. The term describes the process where land in drier areas becomes subject to ‘extreme deterioration’ as a result of human activities. It can be caused by any combination of the following: overgrazing, extracting too much water from aquifers, rerouting of water from its natural sources to population centers, and yes, warming climate. And a new report in the International Journal of Life Cycle Assessment has some pretty terrifying news: over a 3rd of the world’s surface is in danger of desertification.
Desertification is a devastating process in many ways–it leads to rapid biodiversity loss, as wildlife dependent on the depleting water sources die out or evacuate the area. After land has been a victim of desertification, it can no longer be effectively be used for farming or be of productive value–true to its name, the process essentially leaves arid desert where ‘useful’, life-supporting land used to be.
