Evaluation of sustainable development approaches and presentation of new scenarios in South Khorasan province with emphasis on climate changeGlobal warming and its environmental consequences, such as climate change, are the biggest environmental threat on Earth.The effects of climate change have led to water and food shortages, illness, unemployment and migration, poverty, resource tensions and global instability.The purpose of this study is to analyse the effects of climate change on a landscape and its impact on sustainable development.South Khorasan province in Iran, is a region that is in crisis due to the misuse of natural resources.There are many environmental "sustainability ladders".According to the findings, the effects of climate change have a significant and inverse relationship with sustainable development.Hence, the present article introduces four conceptual approaches.It identifies the largest and most vital environmental crises in Iran today, using a hierarchical analysis process and the opinions of 60 experts in the field of environment and urban planning.The degree of threat of each crisis (AHP) is quantified.Finally, the priority of the threat crises and the weight of each of them were obtained as follows: Drought (0.425), Destruction of forests pastures and Agricultural lands (0.222), Air pollution (0.147), Evacuation of villages (0.139) and Loss of biodiversity (0.067).By identifying these priorities, four approaches to each of the crises to deal with the devastation of "ideal sustainable development" were proposed.As an Approach to Drought Crisis Evacuation of villages and migration to "and" air pollution "to address the" strong sustainable development of forests, pastures and agricultural lands and to address biodiversity loss, one of the two approaches to weak sustainable development or "poor sustainable development" approach to cities, pollution control is recommended.The important consequences of climate change for this region are the water crisis, drought and the migration of villagers, and the increase in heat, air and fine dust in the cities.The results show that in order to achieve sustainable development in this region, as a result, with the consequences of climate change, it can be sustainable that must be chosen.
