Changes in vegetation-water response in the Sahel-Sudan during recent decades.

ABSTRACT:

Study region

The Africa Sahel-Sudan region, defined by annual rainfall between 150 and 1200 mm.

Study focus

Understanding the mechanism of vegetation response to water availability could help mitigate the potential adverse effects of climate change on global dryland ecosystems. In the Sahel-Sudan region, spatio-temporal changes and drivers of the vegetation-water response remain unclear. This study employs long-term satellite water and vegetation products as proxies of water availability and vegetation productivity to analyze changes in vegetation-water sensitivity and the cumulative effect duration (CED) representing a measure of the legacy effect of the impact of water constraints on vegetation. A random forest model was subsequently used to analyze potential climatic driv
