Abstract
|
The Sahel is a region where the population has always faced a high degree of climate variability.Over the last two decades, the effects of climate change have exacerbated the already difficult conditions.The Sahel will experience a rise in temperatures combined with highly variable rainfall and an increase in extreme weather events. The purpose of this study is to present good practices in soil and water conservation and soil protection and restoration from the point of view of their contribution to reducing the vulnerability of the region’s population and improving the resilience of its agro-silvo-pastoral systems.
