An ambitious plan to eradicate tsetse, and therefore tsetse-transmitted trypanosomiases, from Africa was launched at the 36th Organization of African Unity summit meeting (Togo, July 2000) in a bold attempt to re-focus attention on one of Africa''s greatest scourges. This plan involves the use of the sterile insect technique to achieve final eradication in areas where the fly is suppressed by more conventional methods (such as traps and targets). In this article, the current aims of this project are questioned on historical, ecological, logistical and financial grounds. [Copyright &y& Elsevier]

In our study we did not address the impact of predicted climate change on malaria incidence because a complete global assessment is reported elsewhere. Regarding the climate surfaces we used, the data set has superior spatial resolution compared with other data sets of similar temporal extent, and has been used to quantify climate change across Africa at 0.5 × 0.5° spatial resolution (although the resulting maps are smoothed to emphasize regional changes). It is inconsistent to assert that these same data are insufficient to demonstrate a lack of climate change. [ABSTRACT FROM AUTHOR]
