Irrigation Potential Lake Victoria, Tanzania
Project: Irrigation Potential Lake Victoria, Tanzania
Client: Nile Basin Initiative
Partners: -
Period: 2008
Aim: Expert opinion on the physical irrigation potential for the proposed sites of Bugwema, Manonga, Isanga, Ngono and Mara Valley in the Lake Victoria Basin, Tanzania
Summary
Within the context of the Nile Basin Initiative (NBI), the Nile Equatorial Lakes Subsidiary Action Program (NELSAP) and the EWUAP (Efficient Water Use for Agricultural Production) are promoting irrigation development in Tanzania. A study was undertaken to evaluate and rank five potential irrigation schemes in the Tanzania part of the Lake Victoria Basin. Schemes included in the analysis are Bugwema, Manonga, Isanga, Ngono and Mara Valley.
The methodology followed in this study to assess the irrigation potential of the five schemes is based on the assimilation approach to ensure the use of all available data, information, publications, local knowledge and expert judgment together. The study focused on the following five thematic areas: (i) land suitability, (ii) water resources assessment, (iii) water requirements, (iv) environmental considerations, and (v) institutional aspects.
Based on testing decision makers preferences it was concluded that three schemes are high in ranking: Mara Valley, Ngono and Isanga. However, only based on the actual decision makers preferences final ranking can be determined.
