Background: Coping with climate change (CC) is part of the way to face this phenomenon. This depends on the understanding of CC and the degree of adaptability to it.Objective: The research was conducted with the aim of measuring the level of nomads' understanding (NU) of CCe and their adaptation strategies (AS) in the face of CC.Research method: The research was descriptive and the data collection tool was a questionnaire whose items were obtained based on interviews.Findings: NU of the effects of CC is not the same. According to them, CC has had the most obvious impact on vegetation. The priority of AS is also different in the face of CC. A positive relationship was observed between understanding the effects of CC and the degree of adaptability in facing CC. Nomads who had a better understanding of the effects of CC have used livestock management strategies to adapt to it. Age and history of animal husbandry had a positive relationship with the level of understanding of the effects of CC. A negative and significant relationship was also observed between the number of animals and the degree of compatibility.Conclusion: The NU of CC and its effects on the ecology of the environment is an important starting point in dealing with the negative effects of CC and choosing appropriate strategies to adapt or deal with it. So that the selection of suitable adaptation methods by the nomads reduces the vulnerability of CC on the condition of livestock and rangeland.

Rangelands as a source of meat, forage, water and soil play a significant role in the country's economy, but the increase in the number of livestock and livestock in the rangelands has eliminated the balance between production and harvest. In this research, the effect of rangeland projects on various indices such as plant diversity, condition, rangeland trend, production and canopy cover percentage in five rangeland (Tajrud, Sangolabad, Ali Abad, Garmab and Dochahi) located in Torbat Heydarieh county has been investigated. For this purpose, after measuring the mentioned indices in the rangelands (treatment) and their adjacent sites as a control, statistical analysis were performed using t-test. The results of the comparison of the mean vegetation percentage indicate that the canopy cover percentage of the planted area with the rate of 51/64% is higher than the ungraded area with a rate of 47.5% with a significant canopy at 5%. Also, despite the high number of production in the area with a plot (73.08 kg / ha), compared to the area without design (67/99), this difference is not significant. The average score of the score for the area inside the project (27.4) and outside the plan (23.4) are not statistically significant with each other. The implementation of rangelands in three regions from all five regions has been proven to negatively affect rangeland tendency. Also, the implementation of the rangeland scheme has significantly increased the Shannon-Wiener heterogeneity indices and Simpson's uniformity in the design, rangeland has not changed significantly in the Margalaf richness index.

Rangelands are among the natural resources which have a considerable effect on environment and man’s life. Iranian rangelands mostly have poor condition and exhausted by intensive over grazing, should be utilized according to their ecological capability and land suitability. The main objective of this study is to evaluate ecological capability and land suitability of Gheshlagh dam’s watershed area-parcel A (In Kurdistan province, western Iran) to develop range management plan. Following data collection; determination of the important parameters for evaluation of rangelands environmental capability in the study area was carried out and then obtained parameters were given values based on Analytical Hierarchy Process (AHP) method. Finally, the obtained values were applied to the important parameters for evaluation of rangelands environmental capability according to technique for order performance by similarity to ideal solution (TOPSIS). The results approved that suitability of a land is classifiable for various types of land uses using MCDM methods. Also according to the results specified that the physical criteria of land have more effective than other parameters to develop range management plan. Moreover, land evaluation of study area showed that eastern parts of the watershed had higher suitability to develop range management plan.
