Economic growth and financial development have brought unfortunate consequences, especially in the field of environment and natural resources, because most of the economic activities are closely related to the environment, and in fact, it can be said that the fate of the environment and the economic growth of societies are dependent on each other. In this study, the effects of globalization, economic growth, and financial development on the ecological footprint in Iran have been investigated.
Material and Quantile regression model was used for this research and for the time period of 1360-1400. This method has gradually become a comprehensive method for statistical analysis of linear and non-linear models of response variables in different fields.
Based on the results; in the first and second (lower) quadrants; Economic globalization, economic growth, energy consumption, financial development, and population density have a positive effect on Iran's ecological footprint, and from the third and fourth quarters onwards, the intensity of its influence on Iran's ecological footprint increases. In other words, the indicators of globalization, economic growth and financial development in the first quarter (Q25) and second quarter (Q50) have a positive temporal correlation with Iran's ecological footprint. Then, as the lag components move away and move towards the third (Q75) and fourth (Q95) quartiles, the correlation between the study indicators and Iran's ecological footprint increases.
Discussion and In Iran, due to the abundance of energy and natural resources, the price of energy is low, which has caused excessive and incorrect use of energy. Granting banking facilities with easy conditions, tax exemptions and such for producers of gas and electric appliances with high energy efficiency and imposing heavy taxes on the other hand, lack of financial support and lack of licensing for producers of energy-intensive appliances with low energy labels, granting customs discounts for Importing gas appliances with high efficiency and not allowing entry or high customs duties for importing gas appliances with low efficiency can be useful in reducing energy consumption and ecological footprint.

The urban sprawl is a dynamic and complex phenomenon, and the most effective factor is land use-cover change Coordinated by with the growth of population and economy, and the resulting changes affect vegetation and the functioning of urban ecosystems. In this paper, identification of the most appropriate classification algorithm to investigate the effect of urban sprawl growth in the east of Tehran city in the time period of 1986 to 2016 on land use-cover changes of Jajroud protected area has been studied.
Material and In this research, the land cover-use changes map was prepared using the supervised classification method and the comparison of three neural network algorithms, minimum distance and maximum likelihood was done in ENVI 5.3.1 software environment.
Land use-cover changes from 1986 to 2016 (period of 30 years) shows the increase of land use-cover area including compact rangelands 58.45%, arid region 91/19%, urban 65/57%, and forest 74/47%. In 2016 compared to 1986.
Discussion and By comparing and examining three supervised classification algorithms including neural network, minimum distance, maximum likelihood, the neural network method has been the most suitable algorithm to identify land use-cover changes.

Nowadays, environmental preservation is considered a necessary matter for society. Industrial wastewater treatment requires various effective processes, due to their unique physicochemical characteristics. The quality and quantity of industrial wastewater are more complicated than human wastewater due to the presence of various industries and must be treated before being discharged into the environment due to their high pollution load. One of the common pollutants in industrial wastewater is heavy metals. The electrocoagulation and filtration process, as an environmentally friendly and integrated process, have a high capability in treating wastewater with high levels of pollution.
Material and In this study, the electrocoagulation process was used on a laboratory scale to remove chromium (hexavalent) and cyanide metal pollutants. In this process, the effect of various parameters, including the initial pH of the wastewater (5-9), reaction time (0-60 minutes), applied electric current (1-3 Amps), and filtration bed height (10-30 cm) were investigated.
Based on the obtained results, the best conditions for the electrocoagulation process include a pH of 7, a reaction time of 60 minutes, an applied electric current of 3 Amps, and a filter bed height of 30 cm. Under these optimal conditions, the removal efficiency of chromium and cyanide was 92% and 88%, respectively. In this way, in the determined optimal conditions, the concentration of chromium and cyanide decreased from 13 and 0.908 mg/L to 1.56 and 0.72 mg/L, respectively.
Discussion and Based on the standards provided by Iran's Environmental Protection Organization, treated wastewater has the ability to be discharged into the environment.

Green spaces are still considered as an inseparable element of human life. Creating green spaces with appropriate and optimal efficiency in residential complexes is always considered essential. In this research, the level of satisfaction of the residents of two residential complexes, Elahia and Amirieh, Kermanshah, was investigated regarding the factors affecting the desirability of green space.

This research is descriptive-analytical. The components of the green space were identified and based on the review of texts, related studies and experts' opinions in the form of a researcher's questionnaire, and with the approval of the relevant experts, it was designed in the form of a Likert scale (five options) and was selected by 143 people from Amirieh Complex and 158 people from Elahia Complex, which in total 301 people were completed. All statistical analyzes were done using SPSS software, descriptive statistics (mean, standard deviation, variance) were used to describe the research components. In the inferential statistics section, the correlation coefficient was used to investigate the relationship between the area of green space and the level of satisfaction of the residents of the complex, the independent t-test was used to compare the level of satisfaction of the residents of the two mentioned complexes, and the Friedman test was used to identify the components of the satisfaction of the residents.

The results indicate that the feeling of satisfaction in Elahia residential complex is higher than that of Amirieh residential complex, and among the 14 factors affecting the satisfaction of the residents of the two complexes, the area of green space had the highest score and green space facilities such as children's play equipment had the lowest score. In other words, with the increase in the area of green space, the level of satisfaction of the residents with the complex also increases.

As a result, 14 components were examined in this research. They should be significantly prioritized in residential complex projects to lead to an increase in residents' satisfaction.

Considering that urban and industrial sewage are one of the main factors of pollution entering the environment; environmental effects and technical and operational risks resulting from it have always been considered in the operating phase. But its effects and risks are also important in the construction phase. Therefore, the current research was conducted with the aim of evaluating the environmental and technical risks of the wastewater treatment plant construction project in the west of Ahvaz with the hierarchical analysis process (AHP) in 2021.
Material and After the study phase, information related to the project was collected through the survey method and presence at the site of the treatment plant, and all executive processes, equipment and facilities were examined. For this purpose, the E-FMEA method and the opinions of experts were used to identify environmental and technical risks. Then, Analytic Hierarchy Process (AHP) was used for weighting and prioritizing the parameters of the used method.
In total, 19 environmental risks and 24 technical risks were identified in the processes of the West Ahvaz treatment plant construction project. Environmental and technical risks were similar in the two stages of construction of buildings and installation of tanks and facilities. In other stages, technical risk was more important than environmental. The number difference between the two technical and environmental risks in the stages of excavation, installation of foundation and skeleton of structures was 50, 25 and 66%, respectively.
Discussion and The comparison of all risks showed that technical risks were about 26% more than environmental risks. In general, the results showed that most of the environmental risks were at an acceptable level and 8 technical risks needed to be resolved as soon as possible.

One of the goals of any economic system is to use tourism capacities in sustainable development, which especially requires the use of marketing strategies in this field. In this research, first, the dimensions of ecotourism are identified through Metasynthesis, and then, through the interpretive ranking process, the most effective dimension is determined in the free zones of Iran.
Material and The methodology of this research was mixed, so that in the qualitative part, first, based on previous research the marketing functions of ecotourism sustainability were identified as the basis of analysis, and then, based on Delphi analysis, the theoretical consensus was determined to provide a theoretical framework for the research. In the quantitative part, was used Interpretive Ranking Process. In this analysis, the aim was to determine the most important marketing functions of ecotourism sustainability in the free zones of Iran.
The results of the research indicated the existence of eight marketing functions of ecotourism sustainability through Meta-synthesis analysis, which were confirmed during two rounds of Delphi. The results in the quantitative section showed the percentage of effectiveness of using education in recycling; management of water consumption, etc. in sustainable ecotourism marketing is higher than other functions of ecotourism sustainable marketing.
Discussion and This research is of theoretical and practical importance due to the creation of theoretical coherence regarding ecotourism and its expansion at the level of sustainability functions of Iran's free zones, which can be effective in identifying the axes that affect this area and develop the field for attracting tourists.
