Restoring degraded grasslands [PDF]

open access: yes, 2018
Grasslands are complex ecosystems comprising numerous biotic and abiotic components. The biotic components are the herbaceous grass and forb plants, soil organisms and grazing graminivores which have biological and physiological requirements. The abiotic components include radiant energy from sunlight; the essential major elements of carbon, hydrogen ...

Responses of Soil Microbial Metabolic Activity and Community Structure to Different Degraded and Restored Grassland Gradients of the Tibetan Plateau

open access: yesFrontiers in Plant Science, 2022
Climate change and land-use disturbances are supposed to have severely affected the degraded alpine grasslands on the Tibetan Plateau. Artificial grassland establishment has been implemented as a restoration tool against grassland degradation.

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

open access: yes, 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 ...

Estimating vegetation cover from high-resolution satellite data to assess grassland degradation in the Georgian Caucasus [PDF]

open access: yes, 2016
In the Georgian Caucasus, unregulated grazing has damaged grassland vegetation cover and caused erosion. Methods for monitoring and control of affected territories are urgently needed.

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

open access: yes, 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.

Using Shapley additive explanations to interpret extreme gradient boosting predictions of grassland degradation in Xilingol, China

open access: yesGeoscientific Model Development, 2021
. Machine learning (ML) and data-driven approaches are increasingly used in many research areas. Extreme gradient boosting (XGBoost) is a tree boosting method that has evolved into a state-of-the-art approach for many ML challenges.

Automatic Grassland Degradation Estimation Using Deep Learning [PDF]

open access: yesProceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence, 2019
Grassland degradation estimation is essential to prevent global land desertification and sandstorms. Typically, the key to such estimation is to measure the coverage of indicator plants. However, traditional methods of estimation rely heavily on human eyes and manual labor, thus inevitably leading to subjective results and high labor costs. In contrast,

Vegetation NDVI Linked to Temperature and Precipitation in the Upper Catchments of Yellow River [PDF]

open access: yes, 2012
Vegetation in the upper catchment of Yellow River is critical for the ecological stability of the whole watershed. The dominant vegetation cover types in this region are grassland and forest, which can strongly influence the eco-environmental status of ...
