Résumé partiel
Rangelands are the livelihood for hundreds of millions of farmers-. An widely accepted definition from the American Society for Range Management (cited after McGuire 1978) is : Rangelands are „…lands on which the native vegetation is predominantly grasses, grass like plants, forbs or shrubs suitable for grazing or browsing use which includes lands revegetated naturally or artificially to provide a forage cover that is managed like native vegetation….”. Rangelands can be found previously in semi-arid areas – due to this fact other agricultural uses than pasture can be found rarely. In Iran, the semi-arid rangelands cover the majority of the terrestrial areas. Regarding the area of rangeland in Iran, different figures can be find in the literature, due to using various definitions. Badripou et al. (2006) estimate that 55% of the Iranian land is occupied by rangelands. Rangelands have a great importance for the society - more than 2.5 million people live as semi-nomads in different regions. The rangelands are also of great economic importance, 6% of the gross national product are meat, medical plants, herbs, and honey. Moreover, the rangelands fulfil important ecological functions such as the provision of biodiversity and the maintenance and preservation of biotic cycles. Since several decades there has been reported dramatic degradation of the rangelands, mainly affected by overuse (untimely grazing, overexploitation and overstocking). Governmental plans as the rangeland management plan and grazing licences rarely contributed to the problem of overgrazing. Obviously the informal institutions play the most important role in extracting the rangeland resources. The central aims of the thesis are • to describe the practical systems of rangeland management in Iran (the case study of Semnan) • To find explanations of the processes of the dramatic degradation of the rangelands as effects of acting of the semi-nomads in the face of governmental programs and informal institutions applied in Semnan Province
