Surface runoff revitalization policy in the context of climate change in the Senegal River watershed

Abstract

In the Senegal River watershed, hydroelectric infrastructure and land use have profoundly altered the hydrosystem, resulting in environmental imbalance. The aim of this study is to propose policy options for revitalizing surface runoff in the Senegal River watershed, using remote sensing, geographic information systems and spatio-temporal modelling tools, coupled with climate change indicators. Several types of data were used.   The Land Change Modeler (LCM) model was used to simulate the data and make projections up to 2030 of land use in the Senegal River basin. In this study, the author chose three scenarios Business-As-Usual (BAU), Rapid Economic Growth (REC) or maximalist scenario and Coordinated Environmental Sustainability (CED) or medium scenario.   The results show that the CED scenario offers hope that the restoration and preservation of plant resources is still possible to ensure the revitalization of surface flows in the Senegal River basin.
