Given that the intensifying global climate dynamics have increased the variability of precipitation, the global precipitation pattern has shown significant spatial and temporal differences, leading to an increase in global drought severity and extreme precipitation events in the future, especially in arid and semi-arid regions. This may seriously affect the stability of vegetation productivity in terrestrial ecosystems.
