The increasing growth and expansion of cities under the influence of population growth and migration, has led to unplanned construction and many changes in the spatial structure, especially the physical development of cities in unfavorable places that require basic guidance and organization. In the present descriptive-analytical research, using Fuzzy ANP method, the development and growth of Yazd city has been evaluated. Using weighted overlap method in GIS the analysis of the development pattern and guiding urban growth has been done. To analyze the effective factors in the development model of urban area, first 7 main criteria (including environmental, economic, demographic, land and housing market, spatial-physical, government plans and policies, and access to public services) with 32 sub-criteria were determined for Yazd urban area by examining the internal and external sources. Then questionnaires were completed by 20 officials of relevant organizations. Using the Fuzzy ANP model, the coefficient of importance of each indicator was obtained and the most important factor in the development pattern of urban areas was determined. The results show that spatial-physical criteria with 0.170, and population with 0.158 have the highest and economic criteria with 0.052 and government plans and policies with 0.035 have the least impact on the growth and development of Yazd. Because region one in the north of Yazd city has less worn-out texture and region 3 in the south lacks fertile agricultural lands, these regions can be suggested for the future expansion of the city.

The growth and development of urbanization has a major impact on the supply of land for construction and urban development in urban areas. Widespread use of urban land for residential use has led to the horizontal expansion of cities and the increase in vacant land within cities, which has rapidly expanded the suburbs. In this regard, the paradigm of intensive urban development, smart growth and the use of vacant land within the city to achieve social and spatial stability and equity are presented. The present article aims to explain how the city of Yazd as a desert and arid city is compactly and extensively developed using the concept of urban density. According to the surveys carried out during the years 1966-2016, the area of Yazd city has increased by about 19.5 times and its population has increased by 6.5 times. During these years, the sharp decrease in gross population density and its significant gap with net population density (154.6) indicate that the city is over-stretched and more spaces are left vacant and inactive in Yazd. An examination of the components of development in Yazd shows that if there is no growth in the outer and surrounding areas in the coming years, all future growth and physical expansion of the city will be limited to the use of vacant land. Within the next 25 years, Yazd will not need to increase its area, and the existing area of the city will meet the residential and non-residential needs of its citizens.

Despite the increasing internationally emphasis on planning and practice in developing local communities for poverty alleviation, the planning system of Iran has not only paied enough attention to the development of local communities and the mechanisms that such communities can deal with poverty, but also planners and decision makers have little information about the types and characteristics of those neighborhoods that are more interested in developing community-based activities. The participation of Yazd city folks in improving their residential environment in the past was a kind of empowerment in form of a skill by which they were prepared to take some greater social responsibilities. It was a ground for strengthening social life and strengthening local functions. But due to the problems caused by physical expansion of Yazd city in the last 40 years and migration of indigenous inhabitants from the old texture neighborhoods of city, there is no way to apply the past social interactions and the sense of previous solidarity in the future. Therefore, the proper understanding of this concept in relation to the development of Yazd city can be considered very important. The present study aims to build a capacity on the bases of sustainable development and to assess the effective factors or effective barriers of building capacity in Yazd city regarding two reagents of general poverty and space-location geographic. The statistical population of the present study includes all household heads of Yazd city, of them 500 people were selected as a sample using a simple random method. The inferential results derived from one-sample T-test indicated that in all four research capacity elements (physical-environmental, economic, socio-cultural, and political) with a significance level less than 0.05, the mean figure of capacity building in Yazd city was different from the expected one. It means that the upper and lower levels of the differences are less than zero. Therefore, it was showed that the average capacity building in sustainable development of Yazd city and its dimensions has a positive and significant effect. As a conclusion, it was confirmed that there is a meaningful relationship between the mechanism of establishment and planning of urban sustainable development and local capacities in Yazd city. Finally, some strategies are proposed to encourage the residents towards the local development of neighborhoods in order to approach the urban sustainable development.
