Do roads lead to grassland degradation or restoration? A case study in Inner Mongolia, China [PDF]

, 2011
We use satellite remote sensing data of grassland cover in Inner Mongolia, China to test whether the existence of and the size of roads in 1995 is associated with the nature of the grassland in 2000 and/or if it affects the rate of change of the ...

Exacerbated grassland degradation and desertification in Central Asia during 2000-2014. [PDF]

, 2018
Grassland degradation and desertification is a complex process, including both state conversion (e.g., grasslands to deserts) and gradual within-state change (e.g., greenness dynamics). Existing studies hardly separated the two components and analyzed it

A Meta-Analysis on Degraded Alpine Grassland Mediated by Climate Factors: Enlightenment for Ecological Restoration

Frontiers in Plant Science, 2022
Alpine grassland is the main ecosystem on the Qinghai-Tibet Plateau (QTP). Degradation and restoration of alpine grassland are related to ecosystem function and production, livelihood, and wellbeing of local people.

Soil structural degradation and nutrient limitations across land use categories and climatic zones in Southern Africa [PDF]

, 2019
Although soil degradation is a major threat to food security and carbon sequestration, our knowledge of the spatial extent of the problem and its drivers is very limited in Southern Africa.

Effect of grassland degradation on soil quality and soil biotic community in a semi-arid temperate steppe

Ecological Processes, 2020
Grasslands provide a number of ecosystem services for human society. Degradation of grasslands results in the loss of biodiversity and leads to the deterioration of ecosystem functions. In order to accurately assess the influence of grassland degradation
