| description | Water System Innovations (WSIs) viz. in situ moisture conservation, rain/runoff Water harvesting, efficient irrigation methods and precision agriculture are successfully introduced in Sub-Saharan Africa as opportunities to improve food production and water availability. Large scale adoption of these techniques demand suitable site selection based on bio-physical and socio-economic parameters. In this study, remote sensing and GIS techniques together with field investigations were used to identify potential sites for adoption of WSIs in Pangani river basin of Tanzania. Based on field surveys and remote sensing data, spatial information like hydronomic zones, bio-physical and socioeconomic parameters was generated and the suitability criteria for each WSI were developed. Analytical Hierarchical Processing and Pairwise Comparison Method were used for parameter weighting. The Model builder and Weighted Overlay Function of ARC GIS were used to develop the Multi-Criteria Evaluation model in GIS. Potential sites for adoption of WSIs were identified and validated in reference to field parameters. |
