At the beginning of the drought in the Sahel in the 1970s and 1980s, rainfall decreased
markedly, but runoff coefficients and in some cases, absolute runoff increased. This situation …

Study region Senegal river (SRB), Niger river (NRB), and Lake Chad basins (LCB). Study
focus We investigated the impacts of land use/land cover change (LULC) and climate …

The joint effect of climate change and of human activities on land cover is responsible for an
increase of the runoff coefficients of the West African Sahelian rivers since the 1970s, as …

The Sahel, a semiarid area set in a fragile context, has been undergoing dramatic climate
and land-use changes since the middle of the 20th century. The effects of these changes on …

In recent decades, the Sahel has witnessed a paradoxical increase in surface water despite
a general precipitation decline. This phenomenon, commonly referred to as the Sahelian …

Abstract Study region Nakanbé River watershed in the West Africa Sahel (WAS). Study focus
This study aims to better understand the hydrological behavior of WAS watersheds, which …

In Sahelian landscapes, land use/land cover (LULC) dynamics and climate variability are
already known to affect the water cycle. In its current practice however, hydrological …

In the Sahel, there are few long‐term data series available to estimate the climatic and
anthropogenic impacts on runoff in small catchments. Since 1950, land clearing has …

This study intends to contribute to the ongoing discussion on whether land use and land
cover changes (LULC) or climate trends have the major influence on the observed increase …

Rainfall and climatic conditions are the main drivers of natural and cultivated vegetation
productivity in the semiarid region of Central Sahel. In a context of decreasing cultivable …
