desertification is specific phenomenon of arid, semi-arid, dry sub humid regions. this phenomenon has a high rate in developing countries such as iran. the main objective of this research was calibration of imdpa model in abuzeidabad (kashan) region with emphasis on land criteria. imdpa model, introduced by iranian researchers to assess desertification intensity in iran. before application, the...

sistan plain is affected by desertification and this phenomenon has serious impacts on roads and socio- economic activities of local people of this region. the main purpose of this study is estimating the current and potential desertification intensity of niatak region of sistan based on micd method. that, through it the working units of this region were prepared as the base map for evaluating ...

knowledge of behavior climatic indexes can be help to planning future programs bahabad study area in the eastern part of the province of yazd with a hot and dry climate, high potential evapotranspiration and low rainfall has a high potential for desertification. the aim of this research is evaluation of classification intensity by imdpa model with emphasis to climate criteria. the indices inclu...

this study used quantifying factors affecting desertification based on the iranian model of desertification potentialassessment (imdpa) to assess the current status of desertification in bordekhun region, iran. bordekhun region has anarea of 214.11 km2 and is located near the city of daiyer in boushehr province. first, a working unit map of the regionwas selected as the basic map for evaluation...

Overgrazing is one of the most primary causes of desertification in semi-arid zones of China. From 1992 to 1994 we conducted a grazing experiment in Naiman (lat. 42◦58′N, long. 120◦43′E, 345 m asl), Inner Mongolia, China to elucidate desertification mechanisms. Our experimental field, which was covered with some short grasses, legumes and forbs, included four plots where grazing sheep numbers d...

the derakhte senged area is located in south of neishaboor town at khorasan razavi province. in this research, desertification intensity of derakht senged area was evaluated using imdpa, one of the newest method to assess desertification potential in arid and semi arid regions of iran. to evaluate desertification intensity, based on the primary research in this area, 4 criteria were selected in...
