Economic assessment of water storage for adaptation to climate change in Sub-Saharan Africa (Abstract only) uri icon

abstract

  • The development of water storage schemes in Sub-Saharan Africa is considered a major aid for agricultural regions with scarce water and anticipated climate change impacts. The selection of storage options is often conducted through monetary assessment of direct costs and benefits. Such an approach, although prompt and straightforward, often leads to reductionism in the assessment process and loss 01 valuable information. This in turn can result in less than optimal decision-making. Against this background, this paper proposes an alternative approach based on an outranking methodology designed with threshold systems and weighting values. Though based on the underlying principle of economic efficiency, the approach proposed avoids some crucial weaknesses 01 cost-benefit related analyses. The methodology has been evaluated to six case studies in Ethiopia and Ghana through the introduction 01 socioeconomic and environmental related indicators
