[Development of the Bandama Valley. Sanitary and social problems].

As with all water resources development projects in countries with hot climate, the man-made lake of Kossou in Ivory Coast presents social and sanitary problems. Although the resettlement and the economic recuperation of the inhabitants are well on the way, the health hazards and especially that of the generalization of schistosomiasis calls for an urgent solution. Though well planed in advance, the creation of this man-made lake, illustrates the necessity at the very beginning of a project that will distrub all the ecology of a region, to establish the total disadvantages and health hazards incurved by the people who live there. To the cost of a project should be added that of measures that would contribute to the reduction of these risks before it is too late.
