This video explores the phenomenon of desertification by examining the environmental and societal causes of the problem. The program begins in Al Merida, Spain, a semi-arid region where scientists are studying the alternate effects of erosion and heavy rainfall on the area's soil. Recent urban migration and overgrazing have also contributed to the loss of ground water and the breakdown of the ecosystem. Techniques, such as terracing, water conservation, drop irrigation, and flood irrigation are discussed as efforts against erosion, both in Spain and on a global scale.
