This study aims to determine the accuracy level at which different forms of land degradation can be mapped from medium-resolution satellite data, and to assess how accurately degraded land can be dete...
During Mongolia's transition to the free market, socio-economic factors such as poverty and profit-seeking have greatly increased small to large-scale mining, as well as illicit activity resulting in ...
This paper presents a study on land degradation monitoring focused in the west part of the MuUs Sandy Land in Ordos, one of the important dry areas in China, aiming to understand land degradation dist...
In this paper, we introduce the idea of documenting operational chains for land degradation assessment using ontologies. We believe that this will help end-users in better understanding the land degra...
Soil erosion is a complex dynamic process by which productive surface soils are detached, transported and accumulated in a distant place resulting in exposure of subsurface soil and sedimentation dow...
The relationship between landuse/landcover (LULC) changes and land degradation in two Mediterranean sites is investigated using remotely sensed and ancillary data. The areas of study, the Xaló river...
The quality of agricultural land fund in the Czech Republic is assessed via a valuation system based on the ecological-productive land evaluation. This system was established in the 1960–1980s after...
An empirical model based on high resolution spatial and temporal remotely sensed data offers the ability to assess the degradation impacts of changes in land cover in a spatial context. In an attempt...
The present study attempts to identify and quantify climate change induced land degradation at watershed and village level in Jaggar Watershed of Eastern Rajasthan using remote sensing and GIS techniq...
Two sites (Apomu and Alabata) measuring 10 ha and representing rainforest and savannah agro-ecological zones, respectively in South Western Nigeria were chosen to evaluate the influences of cropping s...
