Abstract
This Book is based on discussions by consultants of the United Nations Environment Programme who met in Nairobi on 30th October 1979 to discuss reports on rain and storm water harvesting in Africa, Asia, Australia and the Pacific, Central America, China and the Middle East. Water harvesting refers to the deliberate collection of rainwater from a surface (catchment) and its storage to provide a supply of water. This process is distinct from the natural runoff of water into perennial rivers which is then controlled and stored in dams and reservoirs. There are many regions in the world where rainfall is heavy for some months of the year and light for the rest; rainwater and storm runoff, harvested in season and then stored, would help in alleviating the problem of water shortage during the dry season.
