Implementation of the nile basin decision support system for sustainable water management in the congo basin

$5

This paper suggests sustainable solutions to transnational water management problem in the Congo basin. It aims at concerted water and aquatic resources development in this basin of approximately 2,345,000 km². Mineral substances exploitation having shown their limits, some think that water valuation constitutes a reliable alternative towards Congolese economy diversification. At regional level, this study analyzes socioeconomic and geostrategic issues that could arise from increased water exploitation. When, at the same time, current climate changes augur a scarcity worsening of this resource. A water allocation model developed under Mike Hydro coupled with the Nile Basin Decision Support System, presents 12 scenarios for exploiting these resources. Nine of these scenarios include water transfer projects from the Congo Basin to Lake Chad. Impact analysis of these water withdrawals revealed that: current electricity production in DRC of 2,590 MW could increase up to nearly 10,000 MW by 2030 and to about 50,000 MW in 2050. This power could be shared with other countries; agriculture modernization, through crop irrigation and aquaculture, could reach, for example, 500,000 ha in Kongo Central; Construction of Inga 3‘s dam could generate nearly 10,000 jobs; at national and regional level, access to drinking water for all can be guaranteed and, transferring a maximum of 320 m3/s directly taken from the Congo river but never over Ubangi, would help gradually replenish Lake Chad without great impact in the Congo Basin
