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.

As a result of rapid growth of cities and their horizontal expansion, a considerable amount of urban lands has been put away from any efficient applications. Such kind of valuable lands cover 15 to 25 percent of cities’ areas in forms of old-fashions and timeworn textures. The 19th district of Tehran has a strategic situation as the western gateway of the city. At present, inactive industries and abandoned warehouses have occupied a significant amount of areas in district 19. Such areas are susceptible for many problems such as; economic depression, reduction of land values, environmental pollutions (accumulation of garbage and construction waste), visual contaminations, disruption in urban functions (services and accessibilities), reducing permeability in parts of the district, negative impact on environmental security, reduction of vitality and happiness of the urban environment which is necessary for social development of the city. Therefore, the present study titled “Planning and organizing abandoned and disused spaces of district 19” has been done based on the existing necessities and in line with the urban infill development policy. Based on aim, the present study is an applicable one. The research method was descriptive-analytic and data collection was based on both documentary and field methods. After identification of the region and extraction of indicators and criteria, we attempted to identify the abandoned spaces of the region. The organizing strategies of land were recognized using SWOT and QSPM models. Based on priority, they include: redevelopment of abandoned lands in line with the economic and social development of the region, setting tax for abandoned lands and their transactions, allocating disused spaces to required services, giving priority to restoration of lands with access to the internal and external road networks, increasing quality and integrating texture of the region, and creating coherence in the regional spatial organization. Finally, strategic policies and implementation mechanisms of these strategies are also presented.

Infill development is a complex and multifaceted category. The importance of this development policy lies in sustaining the city and protecting its perepherial environment. This paper attempts to identify the areas of infill development, using a descriptive-analytical method and documentary data, and to identify the programs and priorities of the physical development scenario of Tehran metropolitan. The results show that based on a regional and land use prospect, Tehran does not have a same capacity and infill opportunities for all its regions. Thus, the physical development scenario of Tehran needs to pay more attention to the issue in order to reach an internalized development. Reaching such development requires the following attempts as primary bases for a physical development scenario: prioritizing the peripheral areas and areas requiring intervention, utilizing the potential of infill land use for new development in a short period of time, identifying alternatives and spaces for deployment in the areas of redevelopment, preventing the segregation, preserving the integrity of new and redeveloped reserves for settling down of the population, the creation of multifunctional functions and revitalization of target areas in a worn-out textures based on a bottom-up planning approach.
