WF3: Understanding, valuing water, and managing irrigated agriculture in the Nile basin ***ENDED
Apr 15, 2021 1:45 PM - 4:00 PM
Applied GIS and modelling techniques to assess suitability of land for irrigation in the Nile Basin based on soil and topographical characteristics. Found 49.8 million to be suitable, and 7.5 million ha to be highly suitable, for irrigation in the Nile Basin:
Estimated basin-wide economic value of irrigation water for 14 crops based on farm-gate prices. Farming systems fell in four typologies: the intensive system of Egypt, the semi-intensive system of Sudan, and the extensive systems of the Ethiopian Highlands and Nile Equatorial Lakes Region. Found the highest value of irrigation water was for perennial crops followed by vegetables. Staple crops generally had low value of irrigation water. The lowers observed values were for the cash crops cotton and sugar cane.
