Sahel Afforestation and Simulated Risks of Heatwaves and Flooding Versus Ecological Revegetation That Combines Planting and Succession

Studies simulating the large-scale afforestation of African Sahel constantly find warning signals increased risk extreme temperatures and heatwaves resulting from changes in albedo latent heat flow. We review measures underlying three simulation studies, together with a restoration model which compartments are formed by greenbelts to enable succession savanna vegetation, protected hot wind drought. Savanna-like vegetation (around 20% woody plants) will show bright reflective surface drying leaves during dry season rather than constant green color, very different impact on temperatures. derive that simulated risks flooding rain strongly depend species, shape density new vegetation. Ecological concepts expected mitigate or prevent such related climatic risks. Compact does not appear be necessary feasible. A based compartmentalization diverse, climatically adaptable could also used populated drylands, as sustainable temperature balancing solution desertification.
