Spate irrigation: good for people, livestock and crops
Spate irrigation is an ancient form of water harvesting. It is a method of managing unpredictable and potentially destructive flash floods for crop and livestock production. By making water available, it can contribute to increasing the diversity of farming systems where it is found. It is the major source of livelihood for many communities in west Asia, the Middle East and Africa. Despite being the oldest type of irrigation, it is still the least studied, understood and documented.
