The Environment Agency of Japan has been implementing an experimental model project to combat desertification in Burkina Faso based on the United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa, under a six-year plan starting in 1995. The objectives of the project are the transfer of Japan's technology for the effective use of groundwater for combating desertification to help establish a sustainable local community, the collection of knowledge and information from a viewpoint either of software or hardware, which are required for future actions to prevent desertification, and the development of antidesertification technologies. This lecture presents case studies of specific actions taken in Burkina Faso to combat desertification.
