Microbial functional changes mark irreversible course of Tibetan grassland degradation. [PDF]

Nat Commun, 2022
AbstractThe Tibetan Plateau’s Kobresia pastures store 2.5% of the world’s soil organic carbon (SOC). Climate change and overgrazing render their topsoils vulnerable to degradation, with SOC stocks declining by 42% and nitrogen (N) by 33% at severely degraded sites. We resolved these losses into erosion accounting for two-thirds, and decreased carbon (C)

Combatting global grassland degradation

Nature Reviews Earth & Environment, 2021
Grasslands are under severe threat from ongoing degradation, undermining their capacity to support biodiversity, ecosystem services and human well-being. Yet, grasslands are largely ignored in sustainable development agendas. In this Perspective, we examine the current state of global grasslands and explore the extent and dominant drivers of their ...

Chinese degraded grasslands – pathways for sustainability [PDF]

The Rangeland Journal, 2020
The 400 m ha of grazing lands in China, mainly across the north and west of the country, have similar problems to those throughout the steppe of Mongolia, Central Asia and neighbouring countries. The grasslands are in drier regions (50–500 mm) across mainly Inner Mongolia, Xinjiang, Tibet, Qinghai, Gansu and Sichuan, often at higher altitudes on the ...

The diversity and co-occurrence network of soil bacterial and fungal communities and their implications for a new indicator of grassland degradation

Ecological Indicators, 2021
Grassland degradation is a retrogressive succession of grassland vegetation, which leads to the loss of biodiversity and the degradation of ecosystem functions. Soil microbiomes play critical roles in the functioning and services of grassland ecosystems,

The driving factors of grassland water use efficiency along degradation gradients on the Qinghai-Tibet Plateau, China

Global Ecology and Conservation, 2022
Ecosystem water use efficiency (WUE) is an important parameter of carbon-water coupling, which connects the carbon cycle and water cycle. It is crucial to understand the spatial and temporal distribution of WUE in degraded grassland and its influencing ...

Characteristics and trends of grassland degradation research

Journal of Soils and Sediments, 2022
Purpose: Grasslands are the largest type of terrestrial ecosystem on the earth, providing rich and unique ecosystem services. However, climate change and human activities have triggered a global degradation of grasslands, which has become a major ecological crisis.

Global degradation trends of grassland and their driving factors since 2000

International Journal of Digital Earth, 2023
Grassland is the second largest terrestrial ecosystem and a fundamental land resource for human survival and development. Although grassland degradation is a recognized and crucial ecological problem, there is no consensus on the area, scope, and degree ...

Restoring degraded grasslands [PDF]

, 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 ...

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

, 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.

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

Frontiers 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.
