Grassland degradation in the Western of Songnen plain

2011 19th International Conference on Geoinformatics, 2011
Based on RS and GIS techniques, three-period (1986, 1995, 2000) remote sensing images are interpreted in order to gain spatial information about grassland landscape in the Western of Songnen plain, then spatial-temporal dynamics of grassland and the natural, human factor of grassland degradation are analyzed.

Grassland degradation and livestock rearing in Lesotho

Journal of Southern African Studies, 1995
This study is written in the context of marked intervention by external agencies, during the last 20 years. This has taken place within the broad concept of ‘sustainable development’, with the stated desire to ‘develop’ Lesotho's livestock economy, and to conserve the country's grasslands. The paper emphasises the need for social scientific analyses to

A device for mechanical remediation of degraded grasslands

Soil and Tillage Research, 2012
Abstract Conventional tillage practices are traditional methods to restore the degraded grasslands. However, the risk of wind and water erosion increases dramatically. To remedy these degraded grasslands and conserve soil and water, a rotary cutting mechanism named soil-gashing and root-cutting device was designed and tested in typical degraded ...

[Hyperspectral remote sensing monitoring of grassland degradation].

Guang pu xue yu guang pu fen xi = Guang pu, 2015
The distributing of China's grassland is abroad and the status of grassland degradation is in serious condition. So achieving real-time and exactly grassland ecological monitoring is significant for the carbon cycle, as well as for climate and on regional economies.

Alpine grassland degradation in the Qilian Mountains, China — A case study in Damaying Grassland

CATENA, 2016
Abstract Degradation of semiarid grassland and efforts to control that degradation have become pressing issues. However, the inherent characteristics of the grassland and the intertemporal nature of the problem complicate the analysis of degradation issues, and consequently, the search for more appropriate rangeland policies.

Restoration of Neotropical grasslands degraded by quarrying using hay transfer

Applied Vegetation Science, 2013
AbstractAimThe campos rupestres are species‐rich tropical mountain grasslands in southeast Brazil that are threatened by mining and quarrying. Eight years following a strong disturbance (i.e. quarrying for gravel exploitation during the asphalting of highway MG‐010), spontaneous succession did not occur on degraded areas.

Grassland degradation alters plant and soil biodiversity–multifunctionality relationships

Nature Plants
Biodiversity is known to promote ecosystem multifunctionality (EMF), but how grassland degradation influences the relationship between biodiversity and EMF remains unclear. Here, using paired observations at 44 sites (a total of 792 sampling quadrats) along a 2,600 km transect, we test how moderate grassland degradation influences 20 surrogates of ...

Analysis of meteorological factors on grassland degradation in Hulunbeier

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
This paper, using nearly 50 years of meteorological data from four national weather stations of Hulunbeier grassland, analyzes the impact of the changes of temperature, precipitation and evaporation on grassland degradation, the results show that: temperature and evaporation increased significantly and precipitation changed slightly in the study area ...

Deciphering the role of rodents in grassland degradation; A review

Journal of Environmental Management
Grasslands are vital ecosystems that play a crucial role in providing numerous services to both humans and the environment. Healthy grasslands are characterized by diverse vegetation, efficient soil, and abundant microbial communities, which enable them to function effectively. However, these ecosystems are at risk of degradation due to various factors,
