Scientists use satellite images to study the degradation of rangelands in Tanzania uniofyork SciReports
, rangelands are home to one third of the global population, many of whom are pastoralists who depend on the savannahs to meet their daily need for shelter, water and food.
The study found evidence that sites that are currently degraded are more sensitive to environmental shocks such as drought, but retain their recovery potential. This means that the most degraded sites today were impacted more during shock events, and didn't have time to fully recover before the next shock occurred.
Today, such movements are increasingly restricted by fragmentation of rangelands, mainly through increasing agriculture, rendering it necessary for pastoralists to remain in what may otherwise have been only temporarily degraded sites, resulting in declining grassland productivity and increased degradation.Senior author, Dr.
