The Organization pour la mise en valeur du fleuve Sénégal (OMVS) (in German about: Organization for the Development of the Senegal River) is an intergovernmental organization that was founded on March 11, 1972 by the states of Mali , Mauritania and Senegal in Nouakchott , to manage the Senegal River and its catchment area of 289,000  km² . The seat of this organization is in Dakar .

Projects

The goals of the organization are to secure the self-sufficiency with food, to improve the income of the local population and to preserve the natural ecosystems . This was to be achieved by completely artificially controlling the water runoff by building two dams and by making the Senegal River navigable eastwards.

The Diama Dam was built above St. Louis in 1986 to stop the penetration of salty seawater into the river basin and into the groundwater . This enabled year-round irrigation management on the Senegal River without any plans being drawn up at the same time. In 1989 another dam, the Manantali Dam, was built in the upper reaches of the Bafing ( headwaters of the Senegal River). Since then, the Senegal River has been regulated by this dam. The fishing industry also benefits from it, as the Nile perch , which is very popular in Bamako , has since been caught in the reservoir. Much of the project was funded by the World Bank and the EU .

With an established environmental monitoring "observatory" one tries today to master the ecologically unfavorable consequences of the construction projects. For example, the authorities are worried about the death of many trees in the Senegal river valley, the introduction of the weed water hyacinth and the increase in diseases such as Rift Valley fever or schistosomiasis .
