Production systems and water productivity in the Nile Basin

FU Berlin Improved Agricultural Water Management In the Nile Basin Production systems and water productivity in the Nile Basin Poolad Karimi1, An Notenbaert2, Paolo van Breugel2, David Molden1 1 International Water Management Institute, 2 International Livestock Research Institute 1. Production systems Production systems within the Nile basin can be grouped into irrigated agriculture, rainfed agriculture, livestock, fisheries, aquaculture and multiple use systems. Rain fed agriculture is the largest agricultural practice in the Nile basin. More than 87% of the land (37 million ha) is under rain fed agriculture, most of which occurs in the Ethiopian highlands and Equatorial Nile area. Irrigated agriculture is dominated by large scale developments in Egypt and Sudan, while only relatively small areas of irrigation have so far been developed under small scale schemes in the Upper Nile countries. Livestock production in the basin varies from subsistence crop‐livestock production (mixed) to commercial production (FAO, 2000). Significant numbers of livestock are concentrated in the arid and semi‐arid areas of the Nile Basin part of Ethiopia, Kenya, the Sudan and Tanzania. Fisheries are an important contributor to the local populations’ food security and a means of income generating and employment. Figure 1. Production systems map of the Nile Basin 2. Livestock water 3. Crop water productivity productivity Water productivity in the Nile Basin has a large variation. Livestock water productivity in In terms of SGVP/Eta, water productivity is ranging from agricultural systems is the ratio of the 0.01 $/m3 in Sudan to 0.2 $/m3 in Egypt. Results show, in sum of animal products and services general higher land and water productivities in irrigated produced to the amount of water areas in Egypt and Sudan. Rainfed crops water depleted in producing them. Livestock productivity is generally low, except in patches Ethiopia water productivity assessments can and equatorial countries where they are slightly higher. use quantitative indicators of animal In almost more than two third of areas received rainfall is outputs (e.g., kg of meat, milk and not enough to meet crop’s water demand. manure or hectares of land that oxen plough) or indicators of economic and social benefits that people derive from animal keeping. 4.Aquaculture & Fisheries production Figure 2. Livestock water productivity in the Nile Basin In 2007 aquaculture production in Nile basin countries reached 700,000 tons which is worth just over 1 million US$ (FAO). Egypt is the main producer of farmed fish within the basin countries with 91% of total production. Uganda aquaculture production is ranked the second producing 7% of total aquaculture production. Production in the other countries together represents less than 2% of the farmed fish. There is high potential for fisheries development in many locations in the basin, such as the Sudd.
