   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).

   The biodiversity in the Sahel plays a crucial role in providing various ecosystem services. The diverse range of plant species helps in soil stabilization, preventing erosion and maintaining soil fertility. Additionally, vegetation in the Sahel acts as a carbon sink, contributing to climate change mitigation.

   Does the Sahel still grow when it rains?

   • Studied in conjunction with rainfall, the vegetation record reveals that plants in the Sahel still grow when the region receives rainfall. These images contrast March 2004, during the dry season, with September 2004, during the rainy season. The top images show the vegetation index while the lower images show rainfall during the same period.

   What causes environmental degradation in the Sahel?

   • The key form of environmental degradation in the Sahel is land erosion. Erosion occurs with the loss of plant life, root structures and organic matter from the soil, and is linked through a host of interconnected pathways to negative outcomes in the environmental, socio-economic, political and security sectors.

   Is the Sahel a degraded forest?

   • Rangeland, including the Sahel, is not, as some assumptions may imply, ‘degraded forests’, but ‘highly productive, biodiverse ecosystems that support many livestock and people’ ( Scoones 2021 ). Furthermore, grasses can be an equal carbon sink to forests due to their extensive root systems (Carleton 2022).
