due to increasing importance of desertification challenges and its consequences the necessity of sustainabledevelopment achievement in arid and semi-arid regions is essential in order to avoid limited sources asting, increase the efficiency of controlling, reclamation and restoration projects of natural areas. based on the iterature review, it has been recognized that combating desertification ...

risk assessment provides the possibility of planning and management to prevent and reduce the risk of desertification. the present study is aimed to assess the hazard and risk of desertification and to develop management programs in the semi-arid western regions of golestan province in iran. desertification rate was obtained using the iranian model of desertification potential assessment. since...

Karst rocky desertification is a geo-ecological problem in Southwest China because of nature and man-made factors, which restricts the development of local economic and social. Soil and water erosion is one of the most harmful form of rocky desertification, but the management methods still keep in the exploratory stage. Biological soil crust is the organic complexes of biotic components includi...

Over the past several thousand years, arid and semiarid China has experienced a series of asynchronous desertification events in its semiarid sandy and desert regions, but the precise identification of the driving forces of such events has remained elusive. In this paper we identify two rapid desertification events (RDEs) at ~4.6 ± 0.2 ka BP and ~3.3 ± 0.2 ka BP from the JJ Profile, located in ...

Land desertification has become a significant issue of economy and ecological environment in global area. In this paper, we have applied the object-oriented method to the research of Zhenglanqi basin and the West of Badain Jaran Desert which present obviously different characters of china. On the basis of the multi-spectral images of Beijing-1 in June and September in 2006, under the standard c...

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...
