The Greening of the Sahel, Rainfall and Sustainability

A precise understanding of the change in vegetation cover across the Sahel, attributable to donor investments in the Great Green Wall, has been limited because of an underinvestment in measurement. Earth observations combined with site observations show that the World Bank’s support for the Great Green Wall has been successful. Vegetation has been successfully established, land has been rehabilitated, and the density of trees and shrubs have increased dramatically at rehabilitation sites. However, projects did not implement measurement mechanisms to establish how much of the increase of vegetation can be attributed to donor programs versus other important variables including changing rainfall.

Watch: Discussion on the role of increased rainfall on the greening of the Sahel and the need for sustainable practices with professor Matt Turner, from the Department of Geology at the University of Wisconsin-Madison and Oumarou Moumouni, member of the development NGO Groupe de Recherche, d'Etudes d'Action pour le Développement in Niger.

depriving these people of fossil fuel technology will 1) increase their dependency on wood for fuel and vulnerability of these trees, and 2) deny the real benefit of CO2 fertilization in this context
