Nowadays different countries of the world have serious and urgent problems in many social and environmental issues and sustainable development; achieving sustainable development is the goal of every society and attention to welfare and well - being in society is the most effective means to achieve sustainable development. The aim of this study is to investigate the spatial analysis of welfare and social security indices in Iran using multi - criteria decision making technique of CoCoso. The findings show that in the first strategy (Ka), Tehran province with a score (0.042), Khorasan Razavi province with a score (0.041) and east Azerbaijan province have the highest scores in this strategy. In second strategy (Kb) Tehran province with a score (17.55) Khorasan Razavi province with a score (14.734) and Isfahan province with a score (13.104) they have the highest scores in the second strategy. In the third strategy (Kc) Tehran province with a score (1), Khorasan Razavi province (0.981) and East Azerbaijan scored the highest score by scoring (0.938). In the 22 provinces in the medium and deprived state, improving the welfare and Well-being indices in these areas requires special attention of decision makers and decision - makers.

Natural disasters are a phenomenon that neglecting them will lead to irreparable damage. Baqershahr as one of the important cities of Tehran province due to the presence of several active faults and seasonal and permanent rivers around and inside Venice. Behesht Zahra large sanctuary has a high vulnerability to natural and physical hazards, the presence of dense urban fabric, the main fault of Rey Garmsar, rivers north of Tehran and worn texture are factors that lead to the study of effective factors in crisis management. Due to the nature of the research method, it is descriptive-analytical. First, the research findings include the criteria considered in crisis management, including the existence of storage system, specialized equipment and appropriate operational organization, specialized manpower, information system, operational effectiveness and information system for residents, infrastructure and communication facilities. These factors have been done by urban planning experts, urban planning by questionnaire information in the study area and the analysis of factors and variables has been done by multi-factor analysis, variance, regression and Pearson test. In fact, factors and coefficients in storage criteria And support equal to 16.2 percent, specialized equipment and the existence of a suitable structure of operational organization 11.65 percent,

Landscape changes occur by natural trends or disturbing events. The current study evaluated the landscape structure changes of Latian Dam watershed by means of landscape metrics to achieve the ecological approach in order to formulate sustainable regional development and planning for area of the study. Land use changes were identified using four time-series atmospherically-corrected surface reflectance Landsat images from 1987 to 2017.Then,7 metrics in landscape level and 8 metrics in class level were chosen to quantification the landscape structure by Fragstats 4.2 software, in order to analyze the landscape changes. The results and analysis show the increase in NP and IJI, and the decrease of AREA-MN which mean the fragmentation occurs in landscape level. The increase of AREA-MN and NP in built-area class shows the tendency to coarse grain structure (homogeneity), and the decrease of AREA-MN and increase of NP in vegetated area class, shows the tendency to fine grain structure (heterogeneity) in landscape level. These scientific findings of past, present and ability to estimate the future land use of the study area will assist planners and decision-makers to formulate environmental protection plans to conserve natural heritage.

This study aims to investigate the role of heat island in the process of temperature changes in an urban area of Tehran during 2010 and 2018, equivalent to 1389 and 1397. To evaluate the changes, five points were identified on the map of region 1 and its eight regions. Then the middle month of each season from 2010 and 2018 was selected for review. Landsat 8 satellite data were used to analyze the heat island and the effects of urban construction on the intensification of this phenomenon. The maximum temperature data, normalized vegetation difference index, and ground surface temperature were extracted. This study shows that the level of vegetation in 2018 compared to 2010 has decreased sharply, so that it has caused temperature changes and also the creation of a heat island in recent years in the region. The increase in temperature in the morning and noon is observed in all selected months of the four seasons of the year. At the same time, the amount of increase in minimum temperatures was greater than the maximum temperatures.

Nowadays, urban development requires approaches that can overcome various urban problems and changes the abandoned and useless areas which consist of high values and make a significant part of the city into the most dynamic spaces. The case study of this research is three neighborhoods of zone 16 neighboring with the Fadaiyan Islam Axis of Tehran that consist of vast Brownfield and located in the Trade World Zone which can turn this area into a valuable asset for the city of Tehran. After identifying all three neighborhoods and their Brownfield, these neighborhoods were prioritized by sustainable urban regeneration criteria using the ARAS technique. The results indicate that Shahid Besat neighborhood with a desirable rating of 993/0 ranked first, the southern Aliabad neighborhood with a desirable rating of 533/0 ranked second, and the Azeri garden neighborhood with a desirable rating of 264/0 ranked third for sustainable urban regeneration. Finally, Urban Catalyst strategy has proposed which is a tool within the urban regeneration strategy to overcome the challenges of Brownfield Regeneration in their purification and redevelopment.

Urban health planning is a relatively new term coined today by those urban and regional planners who have always sought to link the urban environment with the physical and mental health of urban dwellers. The aim of this study is to analyze the structure of a health-oriented city in improving the public spaces of District One of Tehran. The purpose of this research is applied research in terms of descriptive-analytical method. The analysis of research data was done in two ways, first using descriptive statistical techniques and second using inferential statistical techniques (T-Test and Fisher Test).

Air pollution in the city is one of the most important issues that affect the environment, community health, economy, management of urban areas, etc. The aim of this study was to investigate the effect of space layout components, land use and traffic and road network on urban air pollution. The method of the present research is descriptive-analytical. The statistical population of the study consisted of experts living in Tabriz. The sample size includes 45 people. Descriptive statistical tests, regression in SPSS software were used to analyze the data. The results of this study showed that land use, space layout, traffic and network of roads and urban density have a positive and significant effect on air pollution. Also, among the components related to the arrangement of space, the interconnected component has the most impact. Among the land use components, the green space density component has the opposite effect on air pollution.
