Desertification is a serious threat to the ecological environment and social economy in our world and there is a pressing need to develop a reasonable and reproducible method to assess it at different scales. In this paper, the Ordos Plateau in China was selected as the research region and a quantitative method for desertification assessment was developed by using Landsat MSS and TM/ETM+ data o...

Land degradation is a major threat to the sustainability of human habitation, and it is essential to assess it quantitatively. Assessment of the human-induced aspect is especially important for planning appropriate prevention measures. This paper used the Three-North Shelter Forest Program region as the study area, and assessed the land degradation dynamic using a time series of summed normaliz...

Desertification in Qinghai-Xizang (Tibet) Plateau is part of Chinese desertification. In the past decades, due to the climate warming, the climate condition in Qinghai-Xizang (Tibet) Plateau has been relatively dry. This has resulted in permafrost degradation and other environmental problems. In addition, the vegetation and the soil layer were also destroyed by unreasonable economic activities....

Land Use and Land Cover Change (LULCC) is the most prominent cause of Soil Organic Carbon (SOC) variability in any landscape. Kenyan Arid and Semi-Arid Lands (ASALs) have been facing extensive land use/ cover changes in the last three decades prompting a review on the impacts it has on soil quality and consequently on land degradation. This study was carried out in 2016 in Olesharo Catchment, N...

This document presents proposals for the design and implementation of a Baseline Survey for the UN Convention to Combat Desertification (UNCCD). It has been prepared at the request of the Secretariat of the UNCCD. The Baseline Survey is to be initiated as part of the UNCCD's Ten Year Strategic Plan, and will form the starting point for monitoring long-term trends in desertification so that prog...

Soil degradation is a global phenomenon affecting the productivity of agricultural land. Due to low vegetation cover and aggressive climate, Morocco presents significant case soil through erosion desertification. The Ouergha catchment highly vulnerable this scourge. objective study was assess sensitivity land in area. MEDALUS approach, widely used Mediterranean region, soils degradation/deserti...

Currently, desertification is a major problem in the western desert of Iraq. The harsh nature, remoteness, and size make it difficult expensive to monitor mitigate desertification. Therefore, this study proposed comprehensive cost-effective method, via integration geographic information systems (GISs) remote sensing (RS) techniques estimate potential risk desertification, identify most vulnerab...

Desertification is a global environmental problem, and arid dunes with sparse vegetation are especially vulnerable to desertification. One way to combat desertification is to increase vegetation cover by planting plant species that can realize fast population expansion, even in harsh environments. To evaluate the success of planted species and provide guidance for selecting proper species to st...
