EVALUATION OF SUSTAINABLE DEVELOPMENT APPROACHES AND PERESENTATION OF NEW SCENARIOS IN SOUTH KHORASAN PROVINCE WITH EMPHASIS TO CLIMATE CHANGE

چکیده مقاله

Global warming and its environmental consequences, such as climate change, are the biggest environmental threat on Earth. The effects of climate change led to water and food shortages, Illness, unemployment and migration, poverty, resource tensions and global instability. The purpose of this study is analysis effects of climate change in the country and its impact on sustainable development. South Khorasan province in Iran, is also 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 the four conceptual approaches Identifies the largest and most vital environmental crises in Iran today and uses a hierarchical analysis process and using the opinions of 60 experts in the field of environment and urban planning, the degree of threat of each crisis (AHP) Quantifies. Finally, the priority of 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 Losses biodiversity (0.067). By identifying these priorities, the necessary approaches to each of the crises, to deal with the devastation, "ideal sustainable development" four approaches were proposed. 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 2 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.
