D1-4 Report on the assessment of potential of water harvesting

Huge potential exist in Africa for surface WH as well as groundwater recharge. Most of the study sites belong to areas with high potential. The teams have the tendency of adopting already existing WH techniques as they do not need extension efforts from the researchers. However, they are very reluctant about the introduction of new techniques from elsewhere as this process is somewhat risky and may need some time to be completed. In WAHARA, 2-3 WHT will be test-implemented and monitored in each of the study sites. At least one of these will be an innovative WHT for each country. This will allow stakeholders to see such an innovative WHT, which will make them more familiar with it and which makes things more concrete, thus hopefully provoking a process of adaptation in which the introduced WHT is adapted to better fit local circumstances
