 ABSTRACT

This study aims to show the impacts of global warming on water resources in the department of Bocanda, located in the central-eastern part of Côte d'Ivoire, in a humid tropical environment What are the periods of climate change in this locality? Thus, the Pettitt test was applied to the climatic series from 1920 to 2009 of the Bocanda station This test shows a unique break in the rainfall series in 1968 Thus, a wet period of low temperatures can be distinguished, from 1920 to 1968, where the annual rainfall is abundant, with an annual average of 127014 mm There is also a dry period, from 1969 to 2009, with low rainfall, with an annual average value of 11454 mm, and almost all high temperatures These temperatures increased by 060°C on annual average during the dry period and the rate of reduction in rainfall is 1001% on annual average It is therefore a case of global warming in this humid tropical environment which results in a decrease in rainfall The water balance method has made it possible to highlight the impacts of this global warming on the region's water resources The results show that, in wet periods, real evapotranspiration, which was on average 90546 mm per year according to Coutagne's method, is reduced to 85274 mm in dry periods, a reduction of 582% Annual average runoff, which was 8763 mm in the wet period, is reduced to 79 mm in the dry period, a reduction of 90% Finally, the effective infiltration in wet period is 27704 mm, which is reduced by 2288% in dry period.
