1 Promotion and scaling up of rainwater harvesting technologies: Role of Universities P. Nyamugafata and S. Madyiwa University of Zimbabwe

2 Promotion and scaling up of rainwater harvesting technologies: Role of Universities What technologies are available?  Contours for water harvesting

3 Water Harvesting Technologies infiltration pits, fanya juus, tied ridges, graded contours Basins

4 Problems (Role of Universities) Many water harvesting technologies are labour intensive thereby reducing their adoption – there is need to mechanize (University of Zimbabwe is developing a basin digger) There is need to evaluate performance of different technologies under different soils and climatic conditions (Some of these water harvesting technologies may cause a potential risk of erosion if the quantities of runoff harvested is greater than the capacity of the structures). Water harvesting techniques have been designed in a “one size fits all” approach (technologies suitable for different climatic and soil conditions need to be evaluated) There are no technical guidelines or manuals that farmers can use as reference material for most water harvesting technologies.
