The formation of approaches with the attitude of advocacy planning can be related to the existence and continuity of spatial and socioeconomic inequality and the conventional failures of planning. In Iran, planners who work as urban planning engineers in most of the consulting engineer’s companies, or in person, can use their expertise to encourage citizens to follow their legal rights and to increase their social participation. Examples can be found in plans that are intended to change the land use through the Organization of the Engineering System to eligible city planners. The purpose of the present study is to review the literature of advocacy planning and its application to urban land use adaptation plans. It also tries to show the relations between land use adaptation plans and advocacy planning theory in terms of topics, methods, and goals (the relation between theory and practice). The methodology of the present research is qualitative and data were collected through deep interviewing techniques and nonreactive measures (archival records). The field theory approach has been adopted to analyze the information and to present the final theory. Based on the qualitative sampling method of the typical case study and the theoretical saturation criterion, the views of thirty-five experts in the field of urbanization have been used in this study and their perception of the research questions have been analyzed. Using the "grounded theory" method and data coding, nine core categories were extracted from the initial findings. The result of the present study, with regard to the final core category, indicates that “urban adaptation schemes cover many aspects of advocacy theory in urban planning, and can be considered as a practical dimension in many aspects of Advocacy Planning Theory”. The findings reveal the deep relationship between the theory of planning advocacy and urban land use adaptation plans.

Examination of socio-spatial segregation and differentiations will clearly help better understanding of social and spatial structures of the regions. Isfahan metropolitan region is offering contradictory qualities in its various settlements due to the abnormal increase in growth rate and migrations of different social classes possessing different socioeconomic traits. This study seeks to measure the region’s socio-spatial segregation of educational and occupational groups and to express their spatial patterns. The present study follows a descriptive-quantitative method. It can be categorized as an applicable research which uses a deductive strategy. Based on data obtained from the national census of population and housing in 2011, 14 One-group segregation indices were calculated by Geo-Segregation Analyzer software. Also, the patterns of both groups were mapped by Location Quotient and Hot Spot Analysis (Getis-Ord-Gi) in ArcGIS software version 10.4. The results reveal that the study region generally have a relatively homogeneous environment due to low values of segregation. However, in terms of occupational groups, eastern settlements are suffering from improper conditions. The lower class of the occupational groups has mainly been concentrated and clustered in this part of the region. In terms of educational groups, the western side shows relatively lower segregation than the eastern side but there are still considerable inequalities in central areas.

In compare to driving, cycling and other transportation modes, people pay more attention to their surrounding and connect with the environment while they are walking. Therefore, urban elements closed to the walking paths should be considered as very important elements. Pedestrians, while talking and shopping, accept more impacts from the environment and its characters than any other occasions. Separating the pedestrian spaces from roadways and streets can decrease the effects of noise and environmental pollutions and finally improve the issue of commuting in the city. The present study focuses on designing and constructing five pedestrian zones in metropolitan of Tehran and investigates their functions on urban structure. In the present study, attention is paid to five pedestrian zones of Tehran metropolitan to investigate their effects on urban structure. To do this, the emphasis of the present study is on changes occurred in three criteria including: “urban commuting space”, “green space and environmental health”, and “urban identity”, after construction of the pedestrian zones. Main required data were collected from the questionnaire designed and completed by the local businessmen community and pedestrian zone users. Field and documentary data were used as well. The sample included 350 questionnaires selected by Cochran formula. The results indicated that the studied areas have already moved towards a homogeneous situation due to the construction of pedestrian zones. Also, in one-way analysis of variance, five pedestrian zones showed a significant difference of improvement among the criteria, which means that there is a functional difference between some of them.

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.

The aim of the present study is to analyze the spatial distribution and to show the spatial patterns of advanced producer services (APS) in Ardabil; one of the middle-sized cities in Iran. Sample of the study comprises 2100 activity units in four groups of advanced services, including banking and financial services, healthcare and remedial, real estate, and insurance services. Documentary and field methods are applied for collecting and processing the data. Spatial statistical techniques such as Kernel Density, Average Nearest Neighbor, the local Moran statistics, Cluster and Outlier spatial analysis, Hot Spots and Geographically Weighted Regression (GWR) methods have been used in GIS environment for data analysis, density estimation, distribution pattern analysis and conceptualization of spatial relationships. The results show that, insurance and real estate consulting services are enjoying the highest levels of coverage around the city. The highest densities of ASPs belong to center and south parts of the city. The spatial pattern of the advanced services is spread in type. Spatial pattern and spatial distribution of insurance services and real estate consulting are dispersed around the city, but the spatial pattern of banking, health and remedial services are clustered. The gravity or central point of advanced services locates at the geographical center of the city and the movement path of the advanced services follows a north-south route. There is a significant relationship between population density and some kinds of advanced services. Finally, some recommendations are presented based on the findings of the study.

Nowadays, a large number of cities and settlements are built in places that are exposed to natural or man-made disasters. So, addressing the physical problems of residential buildings of cities and explaining the concept of resilience are two essential issues to be considered. Thus, enough attention should be paid to rehabilitating such problematic tissues. The study area comprises the central part of Hamedan, with 55387 inhabitants and 13663 residential buildings with an area of 29722351 square meters. Based on aim, the present study is an applicable research and based on methodology it is a descriptive-analytical one which follows a physical-structural approach. Investigated indices in the present study include: building structure, material types, number of floors, aggregation, building age, permeability, building quality and number of units. Spatial Autocorrelation method was used to explore patterns of regression and to weigh the spatial data layers. Also Spatial Autocorrelation technique of Moran (Aselin local Morans) has been applied to investigate the spatial distribution pf residential resielience prioritization. Results of the present study show that 22147924 square meters (74.52 percent of the total area), which includes 7280 building blocks locates in low-resielence to non-resielence range of measure. Such a situation necessitates a quick and mitigate planning for rehabilating the area specially in case of building structure, permeability, building quality and building age.

Urban green spaces and parks are considered as a critical component of the urban planning process. Spatial distribution of parks is an important factor in proper accessibility of urban residents to such services. The present study aims at evaluating the coverage of service areas that urban parks provide for people as well as their functions in 10 urban regions of Tabriz city using network analysis and FAHP methods to find the optimal location for expanding and developing the green spaces. The network analysis was done using land use and transit network maps. Then, based on eight effective locational criteria, the location of urban parks was completed. The results indicated that central regions of the city have better access to the neighboring parks than the others. Also, access to local parks is not proper in east, north-west and south areas of Tabriz, but other areas do so. Accessibility to district, regional, and urban parks is suitable in western, eastern and south-eastern parts of Tabriz. Application of FAHP to locating green spaces showed that central and eastern regions of Tabriz are more suitable for creating and expanding the parks and green spaces.

As an interface between the city and citizens, urban neighborhoods have formerly played a major role in shaping and organizing urban activities over the time. They also were encouraging the feelings of belongings, identity, and social relations among their residents by providing the required daily services. However, such neighborhoods don’t play any important roles in various urban plans and programs nowadays. Meanwhile, the idea of sustainable development at neighborhood level is recently emerging among urban planner circles again. Returning to the urban neighborhood solution is considered as a viewpoint that addresses the current problems of cities and urban life. It seeks possible ways to solve the problems using the powerful internal forces and existing social capitals. The aim of the present study is to investigate the role of social capital and its components in neighborhood sustainable development of Illam city. The applied method is analytical-descriptive. Documentary methods are used to complete the theoretical and literature reviews of the study. Field methods and questionnaires are used to accomplish the other parts of the research. The sample includes all the residents of 14 districts of Illam city among them, 383 persons were selected by Cochran formula to complete the questionnaires based on a Cluster sampling. The validity of questionnaire was confirmed by a formal way and its reliability was confirmed by Cronbach’s alpha (0.871). To analyze the data, descriptive statistics (frequency, mean and standard deviation) as well as inferential statistics (correlation and multiple regressions) were carried out. The findings revealed that variables of normalization, civil participation and social solidarity have a positive and meaningful effect. But the variables of linking to social networking and social security have a reverse effect and the variable of social trust has no effects on neighborhood sustainable development in Illam city.
