Remote sensing reveals 69% grassland degradation in Inner Mongolia
Grassland degradation in Xilinhot, Inner Mongolia, China was monitored using remote sensing. The researchers combined various indicators like vegetation cover and biomass with soil characteristics to establish monitoring standards. They found that about 69% of the grassland in the area degraded from 2014 to 2018, but there was overall recovery. Climate change did not have a significant impact, but increased precipitation helped grassland recovery while grazing worsened degradation. This study improves remote sensing monitoring of grassland degradation and provides valuable information for sustainable grassland management.
