A reassessment of the expected development consequences of tsetse control efforts in Africa

Environmental Mapping of Potential Habitats for Anthropod Vectors of Trypanosomiasis in Northern Nigeria

“…Furthermore, it should be noted that vegetation influences energy balance at the boundary layer, often mitigating extremes of local climate (Olagunju, 2015). Accordingly, the resulting component 2 to 4 images from the PCA analysis of this NDVI time-series dataset suggest that there are Journal of Geoscience and Environment Protection some environmental implications particularly resulting from breeding habitats for vector-borne diseases as a result of global change and climatic variability which correlates with studies conducted by Matzke, 1983;Anene et al, 1991;Hay et al, 1997;Kalu, 1995;Patz et al, 2000 andAmeh et al, 2000. For most of the pockets vegetated areas that are indicative of either negative or positive anomalies as the PCA results have shown, they represent areas of ecological zones of special concern.…”

“…These impacts may also influence future disease patterns such that certain vector-borne diseases may emerge in areas where they had previously not been observed and other diseases may become less common in areas where they had previously been very common. With regard to the control of tsetse vectors that transmit trypanasomiasis, one of such control strategies is to eliminate or minimize the fly-to-man, or fly-to-host contact by creating a protective barrier in which a control scheme is employed to prevent the spatial progression of trypanosomiasis (Matzke, 1983;Bourn et al, 1994;WHO, 2017). In line with such efforts to control this endemic disease, Laird 1977;and Dransfield et al, 1991 studied the dynamics of tsetse flies over several decades and in different parts of Africa using various methods including capture-recapture experiments but did not achieve the desired results.…”

“…As animal populations recovered from rinderpest, the area inhabited by tsetse expanded. But with the colonisation of what became Southern Rhodesia and the establishment of a settler economy, tsetse control became a priority as white-owned commercial farms were established (Matzke 1983 ).
