Long about 4100 km, the Niger River in its central part in Mali, extends an area which can reach 40.000km2 called the Inner Niger Delta. Largest wetland in West Africa, delta's hydrosystem is constituted by main branches, effluents and distributaries of the river, ponds rosaries, large lakes and channels. Right in the Sahel, the delta is an important productive ecosystem with a rich biodiversity. One million person derive their livelihood from this ecosystem through key activities such as...

This paper evaluated the impact of climate change on cotton production in Burkina Faso.An econometric analysis resulted in identifying the major factors influencing cotton yields and evaluating the likely effects of future climate change.The results of our study regarding the potential impact of future climate change on cotton yield indicated that further increases in global temperature would significantly reduce the yield of cotton.Future changes in rainfall would also affect cotton...

Abstract West Africa and its people are very vulnerable to climate variability and changes. Increasing the knowledge of plausible trends of rainfall dry spell lengths (DSL) in the rainy season, and of runoff, enables the assessment of vulnerability and adaptive capacity of the system. These predictions are crucial from a water management and policy perspective. The analyses based on regional climate models (RCMs) and observed datasets exhibit non‐stationary behavior and an increase of DSL....

The Sudano-Sahelian zone of West Africa has experienced recurrent droughts since the mid-1970s and today there is considerable concern for how this region will be able to adapt to future climate change.To develop well targeted adaptation strategies, the relative importance of climate factors as drivers of land use and livelihood change need to be better understood.Based on the perceptions of 1249 households in five countries across an annual rainfall gradient of 400-900 mm, we provide an...

Abstract Rural development in the Sudano‐Sahelian region during the past 20 years and future scenarios of change were studied using meta‐analysis of case studies, household interviews and scenario assessment. Households have generally increased their wealth, especially when they diversify out of agriculture. Rain‐fed crop cultivation is more sensitive to climate factors than livestock, but generally climate factors play a limited direct role for local land use and livelihood strategies. The...
