Climate change is creating or intensifying droughts across the globe. The researchers describe how forestation can promote rainfall by enhancing evapotranspiration which in turn increases the moisture in the atmosphere. An idea which they call “targeted rainfall enhancement”. “Models provide evidence that targeted rainfall enhancement through forestation would be beneficial in some cases,” says lead author Arie Staal, an assistant professor at the Copernicus Institute of Sustainable Development. In the article, they also discuss whether targeted rainfall enhancement could be seen as a form of geoengineering.
