desertification refers to land degradation phenomenon in arid, semi-arid and dry sub-humid areas, resulting from various factors including climate variation and human activities. for evaluation and mapping of desertification many research have been conducted leading to regional and local models. in this research, among different existing methods imdpa was selected and desertification intensity ...

abstract desertification could cause reduction of the ecological and biological potential of land which may occur both naturally and artificially. identifying and evaluating the effective factors in development of desertification is very important for better management of land. the aim of this research is to evaluate the sensitive input parameters in the desertification condition by using of ar...

Land degradation and desertification has been ranked as a major environmental and social issue for the coming decades. Thus, the observation and early detection of degradation is a primary objective for a number of scientific and policy organisations, with remote sensing methods being a candidate choice for the development of monitoring systems. This paper reviews the statistical and ecological...

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 ...

desertification is a major problem in many countries. international efforts have been considered to combat and prevent this phenomenon. the most important cases of these measures are the united nations convention to combat desertification. in this study, imdpa model and gis were used to assess desertification phenomena in kashan plain. some indices of climate and water criteria were selected to...

Desertification is a typical disaster risk event in which human settlements and living environments are destroyed. Desertification Disaster Risk Assessment can control and prevent the occurrence and development of desertification disasters and reduce their adverse influence on human society. This study presents the methodology and procedure for risk assessment and zoning of desertification disa...
