Abstract:On the southern boundary of Lake Chad, the South Chad Irrigation Project (SCIP) is a major attempt at agricultural development, obtaining its main source of water from the Lake. When completed, the scheme will cover about 67,000 hectares, affecting at least 100,000 indigenous people who would continue to carry out their agricultural activities mainly on rice, wheat, sorghum, and cotton as part of SCIP. At present, supporting ecological research at the SCIP include those on malaria and schistosomiasis vectors as these may relate to the impact of environmental change. So far, little information is obtainable on the status of malaria in the project area, but it could be possible that increased breeding sites of local insect vectors would increase the level of malarial incidence or higher parasitemia in the community, as observed elsewhere in similar projects. With particular regard to insect vectors, our preliminary research confirms the usual ubiquity of culicines, but that the common malaria transmitters Anopheles gambiae sensu lato and An. funestus are also prevalent and it is noted with interest that An. squamosis and An. pharoensis appear proportionately in large numbers. Study schemes as well as surveillance on the biology and ecology of the insect vector population are discussed. Ref., tab.
