Today, environmental issues have become one of the most important challenges for urban planners, and unbridled urban development has added to their complexity. Resiliency approach planning can, in all respects, create the capacity to deal with the turbulent future. The purpose of this study was to evaluate the environmental resilience of neighborhoods in the district 14 of Tehran. In principle, 23 neighborhoods have been investigated by selecting five environmental indicators. The five indicators were ranked by 30 urban planning experts through hierarchical analyzes of AHP, and then the Gray Relationship Analysis of the status and location of neighborhoods in the district 14 were analyzed concerning each indicator. Finally, the normal line of 0.714 was drawn as the final score in all indices, indicating that 12 neighborhoods had a low resilience. Based on the obtained results, the environmental resilience is reduced while moving towards the western and southwest neighborhoods,. This is in harmony with the texture and population density of the region. Therefore, urban planners need to understand the consequences and environmental costs of physical development rather than physical development itself.

Spatial provision is a combined knowledge dealing with organizing space, which has been developed for the homogeneous and heterogeneous distribution of development in all areas which support sustainable development. Thus, identification and characterization of the spatial distribution of discrimination and injustice have been done in a knowledge-based way. This study aims to examine how such a distributed development is conducted in the province. Among the indicators of development, infrastructure and health facilities opted to investigate; the distribution and development of province’s border city (9 selected cities) have been compared. The methodology of this study is causal-comparative and multi-criteria decision making (MCDM) techniques were used. The results of the study showed that the province was deprived concerning socio-economic status indicators, and spatial distribution. Thus, Zahedan as the political center of the province is the most developed city according the mentioned indexes.

With the population increase in the cities of Iran, especially in the big cities, the demand for public services has increased too. Also, the need to use cars and, consequently, to create multiple gas stations has been increased more than ever before. Despite the fact that Iran is the second largest natural gas supplier in the world, it has long enjoyed the use and export of gas and diesel as the two most commonly fuel used for vehicles in most countries of the world. Given the difference in production capacity and gas consumption in the country, a large part of this fuel is supplied from abroad, which puts a lot of financial burden on buying, transportation and distribution at fuel terminals of the country's economy. The present study is objective as far as its objective is regarded and the method used in this study is a descriptive-analytical one. Using documentary resources and field surveys, a questionnaire consisting of 11 gas stations located in the eastern part of Ahvaz with seven indicators was designed and the stations were analyzed using the Vikor technique. The results of the study showed that among the stations, the position of gas station with Qi zero was ranked first and the position of the gas station of five companies with Qi 0.931 ranked the 11th or the last one.  Therefore, in order to achieve spatial distribution and establish a relative balance in the distribution of services, measures should be taken to strengthen and increase the level of these seven indicators.

Informal economy is a reflection of the changes in the capitalist world, especially in developing countries which plays a major role in creating employment, and generating income. This kind of jobs with their impressive growth causes problems in the field of urban management. The aim of this study was to identify the socio-economic situation of the employed informal sector of Jiroft and the status of its distribution in the city aimed to organize the future plans. The method of this study is descriptive-analytic in which the necessary data were collected through documents and work-style. Continuous discussion about the informal jobs of 130 workers in the social and economic situation was performed and its position on the map was located in order to analyze space and show the status of the cluster analysis, pattern analysis, centrality and ways of distribution of this complication in the form of GIS software jobs. Spatial analysis of the findings made on the informal economy of Jiroft indicated that the spatial distribution of these occupations was normal and because of its placement along the main ways of the city, the occupations have taken a cluster shape with a distribution of the South-North direction and with a standard deviation of approximately 68% of the effects of the consequences.

Urban Management is a decisive factor for improving the life quality for people for which various approaches have been adopted so far. Good governance is the last approach in urban management which concentrates on participation, transparency, responsibility, law force, justifying and accountability in governing. This approach in urban management can produce the desired outputs for organizations and people. Municipality and Islamic council of Ahwaz which are the two important organizations in urban management in Ahwaz can use good governance approach in fulfilling their duties. In this article, the researchers use people’s judgment in a sample community about the performance of municipality and Islamic council to study how much compatibility exists between the performances of these public organizations with good governance principles. The researchers also use a questionnaire for collecting people’s judgment. The results of this survey showed that the average of citizens’ judgment about the consistency of municipal and city council performance with good governance values are 1.41 and 1.22. Respondents say that municipality and council performance in index of rule of law (with average 1.66) is low and in index of participation (with average 0.98) is very low. If we accept the respondents’ judgments about municipality in districts of Ahwaz municipality in this study, judgments show that the performance of municipality management in district 3 with an average of 1.26 has low compatibility with good governance values and municipality management in district 1 with an average of 0.94 has very low compatibility. Generally, the performance of municipality and council in terms of compliance with the principles of good governance, (with average of judgment about 1.31) in a range of 4 values between bad and good, is weak.

Population growth and the desire for urbanization in recent decades have caused many challenges for countries, especially developing countries. Immigrations to big cities that are predominantly related to low-income groups are included, and lack of attention to meet their needs, have complicated urban challenges and, consequently, have expanded the development of informal settlements. Urban Land and housing policies in the metropolitans are the controlling factors of urban expansion and can also trigger urban challenges. Tabriz as one of the metropolitans in Iran faces with many challenges concerning the urban land and housing policies. In this study, the researchers analyze the role of urban land and housing policies on urban development of Tabriz. The research method is analytical and the data are obtained from municipalities, consulting engineers and Roads and Urban Planning Organization. The results of the study showed that in the past decade, the development policies and periphery land use changes to urban development, not only has increased the development costs and supply of municipal facilities, but also the unsuitable policies, destruction of gardens and agriculture. Development of Tabriz to the east and north east which mainly include gardens and agricultural lands has confirmed this process.  Assessment of the Tabriz Statement Number 5 Commission in the development of residential towns in east area is another reason for the role of urban management and decision-makers in Tabriz. The evaluation of the present study showed that in Tabriz development, the policy of land and housing has not been appropriate and unplanned development or emphasis on the development approach of the suburban areas have all led to challenges for the city and has caused the future development of this city to be difficult.

A variety of effects and functions have been enumerated for urban green and natural spaces, one of which is to increase the interaction of residents and neighbors. This issue is so important that today attention to the nature and green spaces of the city as well as the implementation of policies which release the people of the cities from problems such as isolation and cause residents to relate to each other, are of the most important tasks of the urban institutions and this is an important indicator for improving the life quality and community development. In this research, two residential complexes of Ekbatan in Tehran and Pardisan in Qom have been selected as the case study and the purpose of this study is to evaluate the role of nature on neighborhood relations in these two residential complexes. The method is descriptive – analytical and the results of the study showed that concerning the neighborhood relations, Ekbatan Residential Complex score was 3.08 and the score of Pardisan Residential Complex was 2.66. Also, in evaluating the satisfaction of nature and green spaces, Ekbatan and Pardisan scores were 3.81 and 2.61 respectively. In this survey, regarding the relationship between the two variables of nature with neighboring interactions, the Pearson Correlation test results showed a positive and significant correlation between these two variables, so that the overall coefficiency estimate was 0.669. This value was found in Ekbatan to be 0.684 and in Pardisan 0.516, which indicates a stronger relationship between these two variables in Ekbatan Residential Complex. Finally, in assessing the impact of nature and green spaces on neighborhood interactions in residential complexes, the coefficient of determination for Ekbatan and Pardisan were 0.384 and 0.717 respectively. Totally, the findings obtained from the results of 383 questionnaires were used to determine the coefficient of error with a 0.000 error value of 0.627, which confirmed the positive effects of nature and green spaces on neighborhoods and interactions.

Problems of worn-out urban areas in megalopolises are always seen as one of the obstacles to the rapid development in cities, because the lack of adequate infrastructure is a major obstacle in the provision of municipal services in these areas and also residence, employment, leisure and transportation as the main functions of the urban texture have never lacked optimal efficiency. The existing problems such as problems of health, environment, heavy traffic jams, lack of resistance to natural disasters and crime and social damages, are all the causes of the slow development of the city. This article analyzes the factors affecting people's participation in the renovation of the worn-out urban areas in Kermanshah and tries to answer the questions related to the attitudes of the residents about the worn-out urban texture in Kermanshah as well as whether the distressed areas of the modernization of the tissues compared to the expected approach about participation is random or if there is a significant relationship between them. The methodology of this study in terms of the purpose and nature is descriptive. In this study, since the data are non-parametric, chi-square (x2) test was used for the analysis. Also, the use of the variable of participation is divided into three layers of high, medium and low goodness approach was used the results of which showed that there was a meaningful difference between the observed frequencies and the expected level of public participation in the renovation of worn-out urban areas in Kermanshah.

Due to the social nature of man, urban spaces such as squares are considered to be the most important manifestations of social nodes in urban life. While these squares take historical forms, they have such special place and time significance that cognitive documentation of this phenomenon as a major pillar of urban spaces can be used to qualitatively identify squares and public realms that are the foundation of social interaction. In order to have the knowledge of their morphological evaluation to express design principles, consulting with urban design experts is a must. The traditional evaluation of the urban square, due to its specific qualitative dimensions, was considered as a qualitative judgment which often had a high error rate in the survey, so the majority of the studies, generally, are qualitative and based on pure analysis. The purpose of the current research is the phenomenological recognition and qualitative analysis of urban space. Using a combination of several methods, first, the field element in the quality recognition matrix and the six Wolfrum criteria as well as sixteen urban squares were selected from the European cities, In the first stage, by means of Human Subjective Evaluation and Normalized AccumulatedQuality Graph Output, the numerical value was accumulated and then analyzed using the Automatic Geography Evaluation method. Finally, examining the correlation of these two methods led to the qualitative measurement of these urban elements. First, the selected ones were evaluated through HSE method analysis and NAQ extraction primary evaluation about human approach oriented was done. Second, using the AGE method in the analysis, the researchers evaluated the next step of that up to geometrical automotive and correlation between them.  The results of the present study showed that this urban element had many dimensions to be quantitatively extracted. Last, all of the models for evaluation of square qualities in this study are considered the primary step to help the researchers have a functional standard draft while designing.

Towns and their location in the planning of developing countries are part of urban development strategies. Global experiences in this area represent the fact that solving the problems of major cities requires serious support from small urban centers. The purpose of this analytical study is to determine the status of towns in the urban hierarchy system of Kermanshah province. The method used in this study is descriptive-analytic. To analyze the data, the rank-size model and its adjusted type as well as logarithmic Rank Model – Size were used. First, Urban Primacy Index and four urban indices were used. The results obtained from urban hierarchy analysis in Kermanshah province during several census periods have been analyzed and the analysis indicated the  lack of balance  in this province. The results of the study show that the city of Sarpole Zahab was a small town. During several periods from 1375 to 1395 it was considered as an average city. The results of the hierarchical survey of small towns show that cities with a smaller population have lower population stability and lower growth rates rather than the upstream cities. The causes of this instability can be the lack of resource allocation and adequate state budget institutions, inequality in the distribution of income and assets, lack of health facilities and so on. In the case of the strengthening of such cities, on the one hand, it is possible to prevent large migrations to major cities, and on the other hand, the development of these cities can help develop rural areas and create a balance in the region.
