| Abstract
|
In Sub-Saharan Africa (SSA) appropriate water storage can make an important contribution to reducing peoples’ climate vulnerability by increasing water and food security as well as adaptive capacity (Figure 1). However, ill-conceived water storage is a waste of scarce financial resources and, rather than mitigate, may worsen the unpleasant impacts of climate change. Hence, this study sought to determine how climate change (CC) could be better built into the planning and management of water storage in SSA. The study was carried out in Ghana (the Volta Basin) and Ethiopia (the Blue Nile Basin). It comprised analytical work at the basin scale as well as site level analsyes. The basin scale analyses focused on evaluation of CC impacts on existing and planned storage within each basin. The site level analyses focused on understanding economic and sociopolitical aspects of water storage at three “sites” within each basin. Findings were integrated to provide comprehensive insights. Significant effort was devoted to the development of computer simulations of the potential consequences of CC for hydrology in both basins and what this means for different storage options. An approach to evaluate the need for storage as well effectiveness and uitability of different storage types and water storage systems was developed. This attempted to integrate both biophysical and socio-economic aspects of storage within a single framework and provides a basis for evaluating the possible consequences
