标题：Measuring Urban Sustainability over Time at National and Regional Scale for Addressing United Nations Sustainable Development Goal (SDG) 11: Iran and Tehran as Case Studies
摘要：It is evident that relations between political conditions and community development have become sophisticated in recent years. More people now live in urbanized areas, and this ongoing urbanization has various ramifications. Many countries are facing swift urban transformation which alters their regional development patterns. Urban sprawl, migration and rural depopulation, regional inequalities, increasing urban poverty, and social injustice are some of these emerging problems. Assessing regional development for identifying the aforementioned predicaments is really imperative and related to the United Nations Sustainable Development Goal (SDG) 11. However, there are limited studies that focus on the assessment of regional sustainable development at both national and regional scales, simultaneously. Thus, this study aims to fill the gap by developing a robust method that can assess and compare the level of sustainability in various regions and at varying scales. This helps to identify areas where urgent prevention or mitigation strategies and action plans are required. In this study, we strived to evaluate Iran’s regions and Tehran’s provinces based on sustainability indicators. To end this, the authors use factor analysis and F’ANP model in both assessments. The results of the study show that Tehran Province was the most developed province, and its F’ANP result was 2.006. Tehran is 10% more sustainable than the third region in the country which is Khorasan Razavi. Isfahan and Khorasan Razavi provinces were in the next in rank with scores of 1.984 and 1.8, respectively. At the bottom of the list, the northern Khorasan, Ilam, and Kohkiloye-Boyerahmad provinces were in the lowest ranked in terms of access to sustainability indices. It is patently obvious that Iran suffers from uneven development, and the majority of border provinces have moderate or bad situations. This uneven development also intensifies migration to Tehran, which already has one-sixth of Iran’s population which has led todeteriorating social inequity and environmental injustice, nationally. The results of the regional assessment of Tehran also show that there is uneven development in Tehran Province. Tehran County is twice as good and sustainable as 68 percent of the counties in this region. The F’ANP result for Tehran County was 0.580, and it has been ranked first over a period due to the exceptional number of facilities in this region. Tehran County became 20% more sustainable during this decade. After Tehran, Firoozkoh and Damavand counties were in the next ranks with scores of 0.389 and 0.343, respectively. Qarchak, Ghods, and Baharestan counties were the weakest based on the sustainability indices, and their F’ANP results were below 0.2.
