  abstract = {{U}nderstanding evapotranspiration and its long-term trends is essential for water cycle studies, modeling and for water uses. {S}patial and temporal analysis of evapotranspiration is therefore important for the management of water resources, particularly in the context of climate change. {T}he objective of this study is to analyze the trend of reference evapotranspiration ({ET}0) as well as its sensitivity to climatic variables in the {S}enegal {R}iver basin. {M}ann-{K}endall's test and {S}en's slope were used to detect trends and amplitude changes in {ET}(0)and climatic variables that most influence {ET}0. {R}esults show a significant increase in annual {ET}(0)for 32% of the watershed area over the 1984-2017 period. {A} significant decrease in annual {ET}(0)is observed for less than 1% of the basin area, mainly in the {S}ahelian zone. {O}n a seasonal scale, {ET}(0)increases significantly for 32% of the basin area during the dry season and decreases significantly for 4% of the basin during the rainy season. {A}nnual maximum, minimum temperatures and relative humidity increase significantly for 68%, 81% and 37% of the basin, respectively. {H}owever, a significant decrease in wind speed is noted in the {S}ahelian part of the basin. {T}he wind speed decrease and relative humidity increase lead to the decrease in {ET}(0)and highlight a "paradox of evaporation" in the {S}ahelian part of the {S}enegal {R}iver basin. {S}ensitivity analysis reveals that, in the {S}enegal {R}iver basin, {ET}(0)is more sensitive to relative humidity, maximum temperature and solar radiation.},
