   The financial investment needed to bring such ecosystem restoration projects to full scale across the Sahel are estimated to be in the range of $36-43 billion for the period from 2021-2030, excluding costs for capacity building, training and policy change. This is 17-20x more than the funding allocated to the Great Green Wall Initiative during ...

   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).

   Does the Sahel still have agricultural land?

   • Since most agricultural and pastoral lands in the Sahel are still owned by the state, the state can, however, still allocate large areas to private investors, when they find it opportune. Few examples of this exist, yet it may become more relevant as external demands for land for biofuel production and carbon sequestration increase.

   Does the Sahel have a future warming scenario?

   • In detail, the future warming scenario projects a relatively small increase in summer rainfall over the central and eastern Sahel and even a slight decrease over the western Sahel (Fig. 1 f; Dunning et al. 2018; Akinsanola and Zhou 2019; Zhang and Li 2022 ).

   Is the Sahel re-greening?

   • Despite intense human land use, the Sahel has been re-greening in recent decades as precipitation has recovered from the dry period of the 1970s and 1980s. Whether vegetation expands further into the Sahel and Sahara depends in part on the complex interplay among vegetation, climate, and environmental changes.

   Mar 20, 2020 · In the future, the Sahara and Sahelian regions could experience more rainfall than today as a result of climate change. Wetter periods, termed African humid periods, occurred in the past and witnessed a mesic landscape in place of today’s hyperarid and semiarid environment. Such large past changes raise the question of whether the near future ...

   In response to severe land degradation, 11 countries of the Sahel agreed to work together to address the policy, investment, and institutional barriers to establishing a land-restoration program that addresses climate change and land degradation. The program is called the Pan-Africa Initiative for the Great Green Wall (GGW).

   Jan 14, 2019 · PDF 08-16-2019. The Great Green Wall of Africa (GGW) is a pan-African initiative to combat desertification in the Sahara Desert and the Sahel. Originally conceived as a massive tree plantation crossing the African continent from west to east, the GGW has evolved into a set of restoration projects aimed at environmental and human well-being.
