• Resumen

  • The article discusses the ways in which the Sahel-Saharan States of central and northern Africa are using trees to prevent the Sahara Desert from spreading. Referred to as the Great Green Wall, this belt of trees will be 15 kilometers in width and will stretch from Mauritania to Djibouti. The intent of the belt is to protect the Sahel Belt savanna from desertification. The initial stages of planting are scheduled to begin in September 2008.
