Numerous pilot studies and case studies in the Volta Basin have evaluated practices, methods, and tools that could prove beneficial to others, both within the basin and outside of it. However, the question whether an intervention successfully applied in one location has a reasonable chance of success at any other location remains extremely difficult to answer.
From a river-basin perspective, wastewater irrigation is an important form of water and nutrient reuse; however, there are important water quality, environmental, and public health considerations. This report explores the advantages and risks of urban wastewater reuse for crop production in the water-short Guanajuato river-basin in west-central Mexico, and then by a selective literature review demonstrates how common this practice is worldwide.
V3 project focuses on integrated management options at local scale for small reservoirs (SR), in a multiple use context. Integrated management of SR can aim at several objectives: (i) perpetuating infrastructures, obvious condition for socio-agro-ecosystem durability; (ii) protecting and if necessary improving the water quality for the various uses; (iii) reaching and enhancing water productivity potentials; (iv) seeking for equity (pro-poor position).
The reasons why farmers are unable to harness the benefits embedded in technologies and take advantage of business opportunities in livestock sector in developing countries remain unresolved. Drawing on insights from innovation systems approaches, this paper assesses innovation constraints, identifies the bottlenecks and missing links in dairy sector and suggests some instruments needed to address the constraints.
Although irrigation projects often provide water for more than crop irrigation, water allocation and management decisions often do not account for nonirrigation uses of water. Failure to account for the multiple uses of irrigation water may result in inefficient and inequitable water allocation decisions. Decision-makers often lack information on the relative economic contributions of water in irrigation and nonirrigation uses. This report addresses this problem.
