Aug 5, 2022 · Implementing sustainable production practices to rehabilitate soils is a grand challenge of our day, particularly for resource-poor farmers. The West African Sahel requires attention to balancing the need for increasing agricultural production against harsh environmental conditions. While there is much research documenting technologies for soil regeneration in the Sahel, there has been limited ...

Sep 8, 2023 · Therefore, this study submits that climate change orchestrated by change in rainfall is a very strong factor causing reduction in sustainable agricultural growth in the Sahel region. Whereas, greenhouse gas is not a serious factor affecting sustainable agricultural growth in the Sahel region.
Instead, scientists are using satellite images such as these vegetation index images along with rainfall data to determine if the Sahel can still support plant life. Desertification is the process through which productive land (land that supports vegetation) becomes permanently non-productive (on a human time scale).
Causality analysis based on information flow theory affirms this precipitation stabilization between 2003 and 2014. Our results highlight that both the greening and the wetting of the Sahel have been leveled off, a feature that was previously hidden in the apparent long-lasting greening and wetting records since the extreme low values in the 1980s.

future in 4,500 villages in the Sahel will require flexible and multi-year funding resources commensurate with the scale of the needs. WFP will support the governments of the five countries to access additional sources of financial support and will work with all partners to increase investments in the resilience of vulnerable communities.
The rainfall deficit of the Sahel resulted in scores of impacts on forest resources, agriculture, and animal and human health, and subsequent impacts on natural-resources-dependent livelihoods, leading to massive rural to urban migrations (Mertz, Mbow, Reenberg, & Diouf, 2009 ).
