Achieving safe and sufficient water is one of the biggest challenges for Iran and many countries in the world, especially in the Middle East. Among the many solutions, consumption pattern management is considered one of the most popular. For this purpose, this study was conducted in Fanuj city of Sistan and Baluchestan province as one of the most critical cities in Iran. The study was descriptive and analytical in a survey and correlational manner. The required sample was selected using 300 Cochran's formula. According to this sample size, 95% confidence level and 5% standard error rate were determined. The data collection tool was a researcher-made questionnaire. The collected data were analyzed using t-test, one-way analysis of variance and correlation test in SPSS software. The results showed that among the methods of controlling water consumption, the highest effect is related to changing people's attitudes, especially the attitudes of young people. So that young people, by creating a flow in social networks, not only make the biggest changes, but also have the highest effect on changing the attitude of families. According to the study, students reduced their per capita consumption from 151 liters per day to about 140 liters over a six-month period. Therefore, it is recommended to pay more attention to this group in future policies.

One of the environmental problems is the air pollution index, the most important index of which is the volume of suspended particles in the atmosphere, and in the southern and western cities of the country in recent years has increased significantly. The aim of this study was to monitor land use changes due to fine dust in the last three decades using remote sensing and CA-Markov in Ahvaz. The research method was field-analytical. After conducting preliminary studies and preparing appropriate satellite images, they were analyzed and evaluated with different amounts of educational samples and according to ground surveys. The images used were Landsat 7, 5 and 8 satellite images of 2000, 2010 and 2020, respectively. The classification was performed by artificial neural network method and the accuracy of the classification was evaluated and the prediction map of the study area was prepared using the CA-Markov model. The classification results showed that the lands built in 2000 increased from 10637. 34 to 10925. 76 hectares in 2010 and its area increased to 288. 42 hectares. From 2000 to 2010, the green space increased from 1275. 41 hectares to 1279. 99, ie 58. 4 hectares, due to the planting of hand-planted trees during these years to deal with fine dust. These changes have been decreasing from 2010 to 2020 and its area changes have increased from 1279. 99 hectares to 1120. 49, ie 159. 50 area has been reduced.

Although more than 6 decades have passed since the life of regional planning in Iran, the heavy shadow of gaps and spatial imbalances still weighs heavily on regions. Accepting the fact that regional diversity in the development process is inevitable and necessary for the development and progress of a country, we can say that the role of regional planning has forced us to adapt to scientific changes in this field. The genealogy of the development process in Iran shows that the approach of capital accumulation and imposition of specific roles to regions has been done mainly without any cost-benefit analysis and only based on the approach of the pole of growth and concentration of capital in a historical process. This article tries to examine this important issue. Therefore, to understand such a situation, to analyze the economic conditions of the regions; In the form of development indicators such as: population and manpower (urban-rural), employment and unemployment, social participation, the three sectors of the economy, GDP, etc. have been studied using the TOPSIS technique. The results of the research indicate that the Iranian Space Organization has become multilevel and the provinces that are the centers of development have cut their downstream areas in terms of development indicators and by focus of section on attracting capital, Population and industry have caused spatial imbalances inside and outside the region.

The rise of modernism in architecture and urban planning, along with the growing population of the city, restrictions on land and services, demand for housing and economic and environmental constraints, high-rise construction in major cities and the location of these buildings in urban spaces became very important. And it became a good way to control the physical growth of cities and it was necessary to identify suitable areas for the construction of high-rises. The main purpose of this study is to identify suitable areas for the construction of high-rise buildings in Gorgan. This research is of applied type and in terms of nature and method is descriptive-analytical. Data collection was done by documentary and survey methods with a statistical population of 10 people as a sample of municipal urban planning specialists and managers. After examining the influential factors, criteria were determined in four dimensions including physical, social and cultural, environmental and economic. Weighting was performed according to the AHP model and the layers were superimposed using the GIS system. Findings show that areas in the east, west, southwest and center of Gorgan, have a good capacity for the construction of high-rise buildings; In such a way that high-rise construction in these zones leads to proportional distribution and appropriate building density and population in the city, and in the end after prioritizing the zones; Based on the findings, suggestions were made for the establishment of high-rises in suitable areas.

In recent centuries, the rapid growth of urbanization in developing countries, along with an objective approach to development, has added to the objective and mental disorders of Third World cities. Nevertheless, the emergence of a qualitative approach to development concepts provided the basis for raising the issue of quality of life. This is an issue that means the viability of a place today, and its promotion is emphasized not only as a tool to deal with the adverse consequences of conventional growth and development policies, but also as the main goal of development (Faraji et al., 2012: 49). Therefore, the purpose of this study is to investigate the urban quality of life in Manzarie town located in KhomeiniShahr and determine the most effective factors in the formation of residents' satisfaction or dissatisfaction with the current urban quality of life in the area. The method of analysis of this research is descriptive-analytical. To collect information, library and survey methods and questionnaires and to assess the urban quality of life in the study area, factor analysis and t-test were used. First, by t-test, the satisfaction status of each The variable was determined from the respondents' point of view and then using factor analysis and normalization of their scores, the variables were classified into 8 factors and the score of each factor was determined. The results of the analysis indicate the low level of urban quality of life in the study area from the perspective of its residents.
