- Title
Woody encroachment in African savannas: Towards attribution to multiple drivers and a mechanistic model.
- Authors
Conradi, Timo
- Abstract
The author comments on a study that used time series of very high-resolution satellite imagery to determine the extent and rate of woody encroachment in sub-Saharan African savannas between 2002 and 2016. The results present new clues about the mechanism involved in encroachment and the roles of such drivers as rainfall and soils. The most important driver of encroachment rates is said to be the difference between woody cover at the start of the observation period and potential woody cover.
