Long‐term trend analysis in climate variables and agricultural adaptation strategies to climate change in the Senegal River Basin

ABSTRACT The objectives of this study were to investigate the trend in annual precipitation, sunshine duration, wind speed (u 2), and annual and monthly minimum temperature (T min), maximum temperature (T max), and relative humidity (RH) and the adaptation strategies for the Senegal River Basin. Ann...

Description
Summary:ABSTRACT The objectives of this study were to investigate the trend in annual precipitation, sunshine duration, wind speed (u 2), and annual and monthly minimum temperature (T min), maximum temperature (T max), and relative humidity (RH) and the adaptation strategies for the Senegal River Basin. Annual precipitation, T min, T max, RH, sunshine duration, and u 2 for the period of 1950–2000 recorded at St‐Louis, Bakel, Dagana, Fanaye, Podor, and Matam have been analysed using the Mann–Kendall test and Sen's slope estimator. Annual precipitation varied with location from 900 mm registered in 1967 at Bakel to 32 mm obtained at Dagana in 1986. A significant decreasing trend (p
