Abstract

Benin has experienced a significant variation in rainfall with prolonged drought since 1970. In view of the consequences of this extreme phenomenon on vital sectors, such as agriculture, updating the results previously obtained is obviously essential to guarantee optimal management of water resources. The present study aims to characterize the drought in the Alibori watershed in northern Benin. The climatic data used are those made available by the National Aeronautics and Space Administration (NASA) through its POWER “Prediction of Worldwide Energy Resources”; they cover the period from 1981 to 2018. Four approaches were used to assess drought in the basin: the Standardized Precipitation Index, the Climatic Moisture Index, the segmentation of Hubert and Spearman's correlation. The analysis of the precipitation data shows decreasing trends in the lower part of the basin and increasing trends in the middle and upper part. Over the period from 1981 to 2018, we note that the frequency of moderate and severe droughts varies respectively between 31.8% to 39.47% and 15.79% to 18.42%. Extreme drought was observed in 2000 west of the middle part of the Alibori watershed around the point of Latitude 11.0645 and Longitude 2.2944. The data used clearly highlights drought situations in the Alibori watershed.
