Drivers and impacts of changes in China's drylands
Abstract China has 6.6 million km2 of drylands that support approximately 580 million
people. These drylands are at risk of desertification. In this Review, the changes observed in …

A synthesis of the effect of grazing exclusion on carbon dynamics in grasslands in China
Grazing exclusion (GE) is considered to be an effective approach to restore degraded
grasslands and to improve their carbon (C) sequestration. However, the C dynamics and …
