This study, with the life-cycle approach, examines the carbon footprint of a residential tower in the Tehran Metropolitan City in the construction phase. This paper assessed all sources of carbon emissions in the construction phase, including emissions from manufacturing and extraction of building materials, transportation of building materials, construction equipment, vegetation cover around the building, and transportation of construction waste. According to the results, the highest amounts of carbon footprint were estimated at 83% and 14%, which were, respectively, related to the emissions from transportation of materials and construction wastes. The emissions from the construction phase accounted for the 3% of the total footprints. Also in the manufacturing process of building materials, the highest contributions in CO2 emissions were 78%, 10%, and 6%, belonging to concrete, rebar, and cement mortar, respectively. The results of this study can be used as a criterion for comparing and assessing the preventative measures to reduce and manage CO2 emissions in the construction of similar buildings. The approaches that exist for reducing CO2 emissions in construction include management of amount of waste generated and choosing the types of environmentally friendly building materials and providing materials from factories near the site.

This study aims to present a sustainable environmental model using the life cycle sustainability assessment (LCSA) method in Shazand Petrochemical Company. To determine the evaluation indices, two Delphi and DEMATEL-FTOPSIS questionnaires were distributed among 27 and 8 experts in the field of sustainable environmental management. The environmental, social, economic, environmental-economic, socio-environmental and socio-economic factors were selected as the main criteria based on the previous studies. Data analysis was performed using the DEMATEL-FTOPSIS approach. The values of the determined indices were specified by this study, and the management of the company was prepared. The indicated that the BOD/COD output from the company with the value of 2.181 has the highest effectiveness. Moreover, the index of having short - and long-term planning for local sustainable development with the value of 2.416 had the highest influence. Identification of powerful, strategic and high-quality contractors to enter a long-term contract with them in order to get the competitive advantage in the value chain of the company with the value of 0.569 was found to be the best strategy. Eventually, the sustainable management model for petrochemical industry was presented based on the output results. In this model, indices, prioritizing improvement plans and assessing life cycle sustainability were identified as the most important factors among others.

The purpose of this study was to assess the environmental risk of Balarood Dam in Iran at constructional phase. The scientific methods used in this research were the Environmental Failure Mode and Effects Analysis (EFMEA) and VIKOR. In the process of environmental risk assessment, the EFMEA method was used first to calculate the risk priority number (RPN) for each environmental aspect. The identified risks were ranked based on RPN values in the next stage. Comparison of the RPN values showed that the risk of pollution of Balarood River, with a RPN of 125, is in the first priority. In addition, the environmental risks, identified during the follow-up phase, were weighted by entropy method based on severity, occurrence probability, and extent of pollution.Then, the VIKOR method, as one of the multicriteria decision-making (MCDM) methods, was run to evaluate and prioritize the potential environmental risks. The risk of water pollution under high, medium and low conditions, with a weight of 1,300, 1,0...

The present study was carried out to track the changing pattern of climate change at a watershed scale as a risk for the function of land systems. For this, the changing trend of the variables, including maximum and minimum temperature, and precipitation was simulated for the next 20 years using LARS-WG Software, version 5.0. The fifth version of the LARS developed based on the IPCC Fourth Assessment Report includes a total number of 15 models, among which six models (Gfcm21, Hadcm3, Incm, Ipcm4, Mpeh, and Ncccsm) are run with all of the three scenarios SRA2, SRA1B, and SRB1. In order to select the most appropriate model to simulate climate change in the Qarasou Watershed all of the 6 GCM models run with three above-mentioned scenarios were selected, whose average monthly output was compared with the observed data to determine which of the small-scale GCM models has better performance in simulating the meteorological data. The IPCM model was recognized as the best GCM model, in terms of the minimum error to downscale the meteorological data of the watershed. Once the simulation process completed, the climate change trends of the watershed were generated for the different variables, separately. According to the results, rainfall could be the primary climatic driver behind the decreased water supply for agricultural fields. Drier springs and autumns in the coming decades would potentially result in the increasing frequency of spring droughts.

Nowadays, the impact of mankind on the environment is more deteriorating than it used to be the human activities can harm the coastal-marine habitats. So, in order to implement more effective measures for a better protection, it is crucial to determine the sensitive areas of each region. In this regard, ecoregions approach as homogenous biogeographical units can be a firm base to study perturbations in an area along with its habitats. Hormozgan province, in southern part of Iran, is one of the most important coastal regions with a wide range of extensive economic activities and diverse ecological habitats. In this research, the evaluation of the potential sensitivity of this province and its encoded habitats has been studied. Six perturbations were also assessed, according to their distance from each encoded habitat. All the above considerations were measured in a hexagonal network with the use of the analytical network process for the entire study area and also the ecoregions of Hormozgan. The results show that among 39 identified habitat codes, the most perturbed was MA.GS.UT.SG.TF.MM.SH, and the last one was CE.MF.IT.AG.MM. The most potential perturbation was ‘the access roads’, and the last one was ‘oil and gas facilities’. NPGE was a virgin ecoregion with priority in conservation as representative area. In the second step, SHE was the most perturbed one that should be in the second step to be protected and recovered, and ME was in the middle. Therefore, ANP is suitable to study effects of perturbations in habitats.

Recently, there has been increased interest in the use of representative areas as tools for the conservation of marine habitats and species. This has resulted in the declaration of many coastal–marine protected areas around the world. The criteria for the establishment of these areas have been suggested by different authors and international bodies, and for each region or country, that has to be done according to its characteristics, conditions and facilities. In this study, the already established criteria were revised based on new views and approaches at the international levels and the background experiences in the country. This revision was made by using expert choice approach and analytical hierarchy process method. In this regard, a hierarchy tree was made and scored for all physical features and habitats and upon the results, six criteria were selected compared to already established 15 criteria. These were then used with the same method to choose the subcriteria for the Hormozgan province and to map these resources. Altogether, 31 subcriteria were recognized, and then, total score for each area was calculated and encoded into five conservation groups which mapped alongside the coastline and the marine parts. These criteria and subcriteria established in this way are flexible and subject against any changes whenever it is necessary in the future. The result of this study could be applied for other regions of the country and could act for the selection of coastal–marine protected areas.

The carrying capacity is one of the most important tools used in planning natural areas for the sustainable development of ecotourism. For this purpose, the first step was to identify the effective factors in determining the ecological potentials and pressures affecting the ECC of ecotourism in the area. The network model between the effective factors was developed, and then, using the ANP model, PSR conceptual model, the region potentials and ECC were determined for the establishment of ecotourism in a scale of 1:50,000. In this research, the relative importance of effective factors in determining the region ecological potentials and pressures affecting the CC of the region was determined using a questionnaire and Delphi method. A total of 70 questionnaires were completed by qualified experts. Then, the physical CC and the ecological pressure levels of the area were calculated and the final map of the ECC was presented for the development of the ecotourism using WLC technique and the Builder model. The results of this study showed that 20% of the area has a high CC (544 ha), 52% of the area has an average CC (1407 ha) and 28% of the area has a low CC (746 ha).

Abstract –Over six years from 2011 to 2015, direct field observations and waterbirds' surveys were performed in three Ramsar sites (Choghakhor, Shadegan and Parishan). Our results indicated that all three wetlands affected by developing intensive farming systems and lowered species richness. The most important difference existing among the wetlands points to the habitat of the specialist waterbirds, while we found no significant differences in the habitat of the generalist birds. Meanwhile, some completely dependent birds like White-headed Duck (Oxyura leucocephala) have completely disappeared. Our results indicated that 87 percent of the variation in the species richness and abundance can be justified by a combination of water depth, water area, sludge depth, conductivity, total phosphorus, newly developed farming areas and vegetation cover.

The temporal-spatial change of cities is one of the main challenges of managers and decision makers in urban development. In the present study, a parameter related to the evaluation of the capability of Yasuj City was selected, classed, and weighed to determine a desired location for urban development. Accordingly, in order to determine fuzzy maps, all factors and sub-factors were weighed using the AHP and hierarchical technique. Then, the maps of each sub-factor were standardized in IDRIS environment and the considered layers were combined in GIS environment to determine the land suitability for urban development. Next, in order to evaluate the trend of temporal-spatial variation of land use around Yasuj City, the prepared images of the Landsat satellite as well as TM, ETM+ and OLI sensors in Envin 5.1 software related to 1986, 2001, and 2016, respectively, were employed. Finally, based on the changes in land use of Yasuj City, the residential or urban sections widely changed. The changes included different uses such as forests, grasslands, agriculture, and water corpuses. In 1986–2016, the results of changes in land use around the Yasuj City indicated 5% increase in the residential section and 3, 2 and 1% decrease in rangelands, agricultural lands, and water bodies, respectively. Forests, which are located in the outer and inner sections of Yasuj City, have a lot of ecological functions. With the high speed of city development, the ecological functions of forests are decreasing, both quantitatively and qualitatively, and therefore, should be taken into consideration. The results of this study, and the similar studies, indicated that spatial data, especially data related to human settlements (since they are highly changeable), are a good foundation for detailed planning. Such kind of data is also used since they are suitable tools for research purposes.

The maintenance of natural and virgin ecosystems against an unnecessary influx of humans requires a modern and efficient model such as the carrying capacity model to optimize the management and development of ecotourism in these areas. The model is one of the key tools for conservation and sustainability of these areas. The present research attempts to formulate a framework for the ecotourism carrying capacity model for sustainable development of Karkheh protected area in Iran. The information was collected using a citation method as well as, interviews with experts, and visitors, and director of the region with 24 key indicators being regulated by field surveys and library studies. In this study, the network analysis process model, the Pressure-State-Response conceptual model, and Arc GIS₁₀.₅ software were used to determine the potential for the establishment of ecotourism performance in the scale of 1: 50,000. In this research, 70 questionnaires were completed by experts in the field of environment and ecotourism to determine the relative importance of effective pressures. According to the results, the highest values belonged to physical carrying capacity (13,425,681 persons per day), ecological carrying capacity (2,482,226 persons per day), and social and culture (985,706 people per day), respectively. Based on the regional carrying capacity, the physical, ecological, and social carrying capacity index was calculated as 3356, 621, and 246 (greater than one), respectively. According to the results, the region has a high carrying capacity, which can accept visitors.

This research has been carried out for assessing phytoremediation of contaminated soils with 4 concentrations of arsenic by three plants, namely Vetiver grass (Vetiveria zizanioides), Chara algae (Chara vulgaris) and Water hyacinth (Hyacintus orientalis). The experimental results showed that at least two sampling times were significantly different. In addition, at least two plants were also significantly different in terms of percentages of total arsenic that were removed from the soil of the pots, as well as significant interactions between plant and arsenic concentrations. The results obtained from the thermodynamic studies show that, obtained by zero Gibbs free-energy, the process reached an equilibrium on the 60th day of the experiment, and, in fact, the adsorption of arsenic after the 60th day would be negligible.

The municipal waste management has always been one of the most challenging environmental concerns. Today, although different strategies have been developed, sanitary disposal of municipal waste is still considered as one of the most widely used alternatives, especially in developing countries such as Iran. To investigate the land capability of Pishva, for landfill sitting, the important criteria were categorized in two groups of ecological and socioeconomic and then a multi-criteria decision-making model was used with decision-making trial and evaluation decision-making trial and evaluation (DEMATEL)-analytical network process (ANP) approach. First and foremost, the interaction of criteria was determined implementing DEMATEL. It was found that the soil depth criterion not only is the most effective but also is the most influenced one. Moreover, ANP structure was developed to weigh the criteria. In comparison to socioeconomic criteria, ecological ones play a more significant role. Afterwards, factor maps and constraints were standardized using fuzzy and Boolean logic, respectively, and all layers were combined to generate the final capability map of Pishva applying WLC method. The capability map showed that 71% of the area is not capable of landfilling, and only 5% of Pishva has a high capability. The results proved the great effectiveness of the methods proposed in this study.

The present study aimed at assessing tourism potential of a place to meet requirements of sustainable development policies. We studied the Haraz watershed because of its particular environmental characteristics and a high potential for ecotourism. The required data for this descriptive-analytical research were collected by combining field and desktop studies. First, the ecotourism capability assessment of the area was done using Arc GIS 10.3 software based on the Hyrcanian Forest Tourism Development Model for concentrated tourism and extensive tourism. Next, the most important effective indices included (i.e., 19 indices) were determined by Delphi questionnaire and SPSS 17. Finally, AHP technique was applied to analyze the body mass of the indices in order to verify the validity of the model. The results show that 0.0044, 01.3, 3.52, and 37.71% of the study area is suitable for concentrated ecotourism (grade 1), concentrated ecotourism (grade 2), extensive ecotourism (grade 1), and extensive ecotourism (grade 2), respectively. Based on the model applied, slope, direction, and fundamentals (infrastructure) with the body masses of 0.232, 0.116, and 0.115 were identified as the first priorities. Comparing the results of this model and AHP confirms the validity of the model. To strengthen the tourism development potential of the watershed and protect its ecosystems and biodiversity, it is necessary to choose a proper development model. Failure to identify the existing capacities and the field’s sensitivities can cause dissatisfaction of local residents and also damage to the ecosystem of the area.

Abstract Many green school frameworks exist for guiding schools toward sustainable choices. Some global standards and global green school rating systems are similar to green school rating systems found within individual countries. However, wide-ranging global guidance cannot be generalized to unique and varied national circumstances. Countries use a host of methods to rate green schools. The purpose of the current study was to design and validate a national rating system for green schools in Iran that is based on global standards. The rating system was built with insights from experts and from principals in Iranian green schools. Qualitative and quantitative measurements including: Pseudo Delphi, focus groups, Thurstone Case V, online survey and conjoint analysis were applied to design the national rating system. Four classes of green schools have been proposed: Excellent, Very Good, Good and Non-Green. This system allows the status of individual schools in Iran to be judged with respect to a national rating system. . This article introduces the concepts, requirements and a national rating system for green schools in Iran. The goal of green schools is to cultivate better educated pupils more aware of sustainability.

Cutaneous Leishmaniasis (CL) is a neglected tropical disease that continues to be a health problem in Iran. Nearly 350 million people are thought to be at risk. We investigated the impact of the environmental factors on CL incidence during the period 2007- 2015 in a known endemic area for this disease in Isfahan Province, Iran. After collecting data with regard to the climatic, topographic, vegetation coverage and CL cases in the study area, a decision tree model was built using the classification and regression tree algorithm. CL data for the years 2007 until 2012 were used for model construction and the data for the years 2013 until 2015 were used for testing the model. The Root Mean Square error and the correlation factor were used to evaluate the predictive performance of the decision tree model. We found that wind speeds less than 14 m/s, altitudes between 1234 and 1810 m above the mean sea level, vegetation coverage according to the normalized difference vegetation index (NDVI) less than 0.12, rainfall less than 1.6 mm and air temperatures higher than 30°C would correspond to a seasonal incidence of 163.28 per 100,000 persons, while if wind speed is less than 14 m/s, altitude less than 1,810 m and NDVI higher than 0.12, then the mean seasonal incidence of the disease would be 2.27 per 100,000 persons. Environmental factors were found to be important predictive variables for CL incidence and should be considered in surveillance and prevention programmes for CL control.

Cutaneous leishmaniasis (CL) is a vector-borne human disease caused by Leishmania, a parasite transmitted by sand flies. CL is endemic in the Isfahan Province, Iran. This study was designed to identify the climate and environmental factors associated with CL incidence in Isfahan Province. Data included incident cases of CL, climate, and environmental factors, which were collected across 23 districts of province from 2007 to 2015. Analyses were performed with generalized linear models (GLMs) to fit a function to the relationships between the response and predictors. We used negative binomial regression due to over-dispersed distribution of CL cases. The effects of all seven climate and environmental factors were found to be significant (all p < 0.01), and the model explained 40% of the deviance of CL incidence. There was a positive relation between mean temperature, relative humidity, and slope of area with disease incidence; however, negative association was demonstrated between maximum wind speed, rainfall, altitude, and vegetation cover with CL incidence. Cutaneous leishmaniasis continues to be a widespread challenge, especially in northwestern parts of Iran. Climate and environmental factors should be considered when selecting the most appropriate strategies for preventing and controlling CL.

The rapid growth of municipal solid waste (MSW) is considered one of the greatest environmental challenges in both developed and developing countries. Among the numerous approaches in solid waste management, the sanitary landfi ll is still the most common in many countries, including Iran. The multiplicity of factors affecting MSW landfi ll siting on the one hand, and the importance of applying an effi cient method on the other, has led to conducting multi-criteria decision-making integrated with geographic information system (GIS) to evaluate Hassan-Abad land capability. Therefore, 20 criteria were categorized into ecological and socio-economic classes, and the analytical network process model was used to compute the weights. Statistics show that the most considerable items in landfi ll siting are distance from roads and built-up areas and soil with weights of 0.080466, 0.074147, and 0.062027, respectively. Moreover, the fi nal capability map generated by the weighted linear combination method represents that 82% of the study area has no capability for landfi ll siting, while low, moderate, and high capability classes cover 12%, 5%, and 1% of Hasan-Abad, respectively. The results indicate the effi ciency of the integrated method in land capability assessment for MSW landfi ll siting.

Environmental responsibility in school has led to the emergence of a variety of criteria to administer green schools' contributions to sustainability. Sustainability criteria of administrative green schools need validity, reliability and norms. The aim of the current study was to develop and validate assessment criteria for green schools in Iran based on the role of academia. A national survey was conducted to obtain data on sustainability criteria initiatives for green schools and the Iranian profile was defined. An initial pool of 71 items was generated and after its first edition, 63 items were selected to comprise the sustainability criteria. Engineering-architectural and behavioral aspects of this sustainability criteria were evaluated through a sample of 1218 graduate students with environmental degrees from Iran's universities. Exploratory factor analysis using principal components and promax rotation method showed that these 9 criteria have simple structures and are consistent with the theoretical framework. The reliability coefficients of subscales ranged between 0.62 (participation) and 0.84 (building location and position). The study's survey of correlation coefficients between items and subscales illustrated that those coefficients varied between 0.24 and 0.68.

Urban environment has evolved over time and space, as the outcome of dynamic interactions between socioeconomic and biophysical processes operating over multiple scales. In the case of infinite expansion of urban population and human activities beyond “limit of urban capacity,” local urbanites would never achieve prosperity, but also be disordered by deteriorations within socioeconomic and ecological aspects. On this basis, this study aims to suggest a GIS-based model, combined of TOPSIS along with fuzzy modeling, in GIS environ, in order to evaluate Urban Environment Carrying Capacity. Suggested model was planned on the basis of desirable and the maximum accepted limits of chosen indicators, used to determine hot spots. To this aim, Shemiran City was studied. Results showed that at the studied area, 43, 44 and 10% had Degree 2 (low pressure), Degree 3 (median pressure) and Degree 4 (maximum pressure) of carrying capacity, respectively; also, only 3% was at critical state. None of the studied districts has desirable degree of carrying capacity.

ABSTRACT: Sustainable urban development is a new concept of fundamental environmental metropolitan management that not only creates the demand for changing the concepts of economic development, but also affects social development. The current study provides a conceptual model of a sustainable environment pattern In District 22 of Tehran that depends on the relationship between environment and economy, and a network of urban function, which Included transport infrastructure and community centers and economic and regional level in support of the ecological services in Tehran. This landscape often had discrepancies with the development of the city between the layers and the creation of ecological fragile areas. The main objective of the study was to determine the sustainability indicators and create a future development model for District 22 of Tehran. The data was collected by having a review of similar studies and field research on the subject and therefore the effective factors were identified. After accomplished proceedings, the questionnaire was prepared and the results were used in SWOT charts’ grading after analyzing at interior and exterior matrix. Ultimately, quantitative strategic planning matrix (QSPM) was performed based on the results and analysis. This process provided a comprehensive model for sustainable urban development as sustainable development urban landscape pattern.

Environmental risk assessment is a step towards identification, analysis, and classification of risk factors and thus reduction of the possibility of adverse consequences. In this research, a novel approach for environmental risk assessment on groundwater pollution is applied. By combination of aquifer vulnerability DRASTIC map, pollution severity and prioritizing of the plain regions by the TOPSIS method, more sensitive regions of Qazvin aquifer in Iran are identified. In the first step, seven hydro-geological characteristics of the aquifer are overlaid to produce the potential vulnerability map. Nitrate is used as the pollution parameter and its value in monitoring wells is measured by sampling. Spatial distribution of nitrate concentration is investigated using the ordinary kriging method. The TOPSIS ranking method is also applied to estimate the probability of occurrence of pollution based on five affecting criteria defined and quantified in regions of the aquifer. By production of these three layers, the risk map of the aquifer is generated. Results indicate that 9% of the area of the aquifer is categorized in the high risk level which needs an emergency recovery action plan. Also, sensitivity analysis on the parameters of the aquifer vulnerability shows the effect of the soil media more than other parameters.

Leishmaniasis is a parasitic disease caused by different species of protozoan parasites. Cutaneous leishmaniasis (CL) is still a great public health problem in Iran, especially in Isfahan Province. Distribution and abundance of vectors and reservoirs of this disease is affected by different factors such as climatic, socioeconomic and cultural. This study aimed to identify the hotspot areas for CL in Isfahan and assess the relations between the climatic and topographic factors with CL incidence using spatial analysis. We collected data on the total number of CL cases, population at risk, vegetation coverage, altitude and climatic data for each district of the province from 2011 to 2015. Global Moran's Index was used to map clustering of CL cases across districts and the Getis-Ord (Gi*) statistics was used to determine hotspots areas of the disease in Isfahan. We applied overlay analysis to assess the correlation between the climatic and topographic factors with CL incidence. We found the CL distribution significantly clustered (Moran's Index=0.17, P<0.001) with the Ardestan and Aran va Bidgol (P<0.01) districts along with the Naein and Natanz districts (P<0.05) to be strong hotspot areas. Overlay analysis revealed a high incidence of CL in areas with relative humidity of 27-30%, mean temperature of 15-19°C, mean precipitation of 5-20 mm, maximum wind speed about 12-16 m/s and an altitude of 600-1,800 m. Our study showed that spatial analysis is a feasible approach for identifying spatial disease pattern and detecting hotspots of this infectious disease.

The aim of this study was to determine suitable areas for construction of wind farm in Takestan Plain as one of the main wind-prone areas in Qazvin Province. To this end, one of the widely-used multi criteria decision making techniques (Analytical Hierarchy Process (AHP)) was used. The site selection criteria were divided into three main groups of environmental, technical and geographical. Further, buffer zones around wind farms were considered as constraint and excluded from site selection analysis. After weighting the criteria, wind speed was recognized as the top-priority criterion while slope and distance from population centers were ranked second and third, respectively. The obtained results indicated that the western areas of Takistan County, over an area of 433 ha, have a great potential for establishment of a wind farm.

The ever-increasing development of cities due to population growth and migration has led to unplanned constructions and great changes in urban spatial structure, especially the physical development of cities in unsuitable places, which requires conscious guidance and fundamental organization. It is therefore necessary to identify suitable sites for future development of cities and prevent urban sprawl as one of the main concerns of urban managers and planners. In this study, to determine the suitable sites for urban development in the county of Ahwaz, the effective biophysical and socioeconomic criteria (including 27 sub-criteria) were initially determined based on literature review and interviews with certified experts. In the next step, a database of criteria and sub-criteria was prepared. Standardization of values and unification of scales in map layers were done using fuzzy logic. The criteria and sub-criteria were weighted by analytic network process (ANP) in the Super Decision software. Next, the map layers were overlaid using weighted linear combination (WLC) in the GIS software. According to the research findings, the final land suitability map was prepared with five suitability classes of very high (5.86 %), high (31.93 %), medium (38.61 %), low (17.65 %), and very low (5.95 %). Also, in terms of spatial distribution, suitable lands for urban development are mainly located in the central and southern parts of the Ahwaz County. It is expected that integration of fuzzy logic and ANP model will provide a better decision support tool compared with other models. The developed model can also be used in the land suitability analysis of other cities.

Abstract Many assessment systems for green schools exist to guide schools toward environmentally responsible choices. To identify a nation's green schools, an assessment system must be developed for their selection. When green school standards are lacking, measures must be created, including an information model enabling decision makers to recognize these schools. The aim of this study is to create an integrative system for assessing green schools in Iran and to develop scientific support in school selection, in order to avoid hasty choices and to respect the selection of these schools. In this study, by using fuzzy multi-criteria decision making methods, the criteria of green schools have been gauged across 6 criteria and 15 sub-criteria, using a consistent testing methodology. This renders paired comparisons more reliable. Ghazanfari and Mikhailov methods were utilized. To evaluate practical applications, the developed criteria were used in assessing 5 selected green schools in Tehran. The integrative assessment system with proposed criteria showed that green schools 5, 3, 4, 1 and 2, respectively, have earned first to fifth rank in terms of proposed criteria for green schools. Establishing an assessment system and its application through methodology limits incorrect choices, removes the green schools' selection from the domain of non-specialists, restrains subjective methods, and puts selection into the hands of professionals and specialists with scientific support. Due to the need to communicate effectively, to engage experts and to address the complexity involved in the assessment system for green schools, the proposed integrative system was designed to assess green schools.

345 ABSTRACT: The present study was conducted to assess the possible risks induced by construction of Gavi Dam in Ilam Province; western part of Iran, using MIKE-11 model and technique for order of preference by similarity to ideal solution. For this purpose, vulnerable zone of the dam site against the flooding risk of Gavi River was calculated for different return periods. The flooding zones were stimulated by MIKE-11 model. In order to check whether or not the dam construction could affect the quality of the Gavi River, the physicochemical quality of the river water was also tested. Afterwards, a questionnaire was prepared containing an inventory of possible risks supposed to be induced by construction of Gavi Dam. The questionnaires were placed at disposal of experts to score the items based on their importance. The questionnaires were then analyzed using SPSS Software, version 16. According to which, a total number of 12 risk factors were identified. The dam construction risks were qualitatively assessed by preliminary hazard analysis. Based on the results, 3 of 12 identified risks were recognized unacceptable. The shortlisted risks were prioritized at final step using technique for order of preference by similarity to ideal solution. “Habitat fragmentation” with a weight of 0.3002, “water pollution” with a weight of 0.295, and “impacts on aquatics” with a weight of 0.293 were identified as three top priority flooding risks. Among the most important corrective measures for mitigation of the risks at construction phase can be pointed to “restoration of the land cover”, “conservation of areas surrounding the dam as a new wildlife habitat”, “prevention of water contamination”, and “conservation of fish spawning sites”.

In recent decades, necessity to protect environment has been a serious concern for all people and international communities. In appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. As a result, implementation of programs to protect species and ecosystems is of great importance. The current study was carried out to implement a comprehensive strategic environmental management plan in the Mond protected area in southern Iran. Accordingly, the protected area was zoned using multi criteria decision method. According to the numerical models, fifteen data layer were obtained on a scale of 1:50,000. The results revealed that 28.35% out of the entire study area belongs to nature conservation zone. In the following step, in order to offer the strategic planning using strength, weaknesses, opportunities and threats method, a total number of 154 questionnaires were prepared and filled by the relevant experts. For this purpose, after identifying the internal and external factors, they were weighted in the form of matrices as; internal factor evaluation and external factor evaluation. Analytical hierarchy process and expert choice software were applied to weight the factors. At the end, by considering the socioeconomic and environmental issues, the strategy of using protective strategies in line with international standards as well as a strong support of governmental national execution with a score of 6.05 was chosen as the final approach.

AbstractI dentifying the environmental hazards of jack-up drilling rig, which is used as an exploratory drilling and offshore service platform, yet has been under intense discussion. Risk assessment along with determining the likelihood of an event occurrence and the severity of its consequences can be a useful tool for identifying the priorities and making satisfactory managerial decisions. In this study, the environmental risks attributed to jack-ups in the offshore area of Iran around the South Pars gas field were studied, and finally a new mathematical model for the environmental risk assessment in this area was presented. Due to qualitative nature of some indefinite factors, fuzzy logic was applied in this model. Moreover, the model design was tailored to the ecological and environmental conditions of South Pars gas field, and several sources of risk were aggregated for the final environmental risk assessment of jack-up drilling rig. The results indicated that the total risk calculated for jack-up in transportation was tolerable and limited management measures were required. However, for the jack-up operation risks, the site was found to be faced with “unacceptable risk” or requiring extensive management measures.

Dehloran is located on the southeastern Ilam Province. It has a great potential for tourism development due to natural, cultural and historical attractions including national natural monuments as well as three rare phenomena of hot springs, bat cave and bitumen springs. In the current study, TOPSIS and AHP methods were applied to conduct the land capability evaluation study. A total number of 16 criteria and 10 constraints were initially determined and then; each map-layer was standardized using fuzzy and Boolean logics. In order to zoning the study area in terms of ecotourism suitability degrees, the raster layers derived from each environment were overlaid. Based on the obtained suitability degrees, the study area was categorized into three classes and final land capability evaluation map of Dehloran County was prepared. The results obtained from AHP Method indicated that Markazi District has the highest number of polygons with high suitability. The districts of Zarrinabad and Mousian are rated in the next priorities, respectively. According TOPSIS Technique, Markazi with a score of 0.910, Zarinabad with a score of 0.241 and Mousian with a score of 0.037 allocated themselves the first to third ranks, respectively. This shows that the results of the two methods are consistent with each other.

ABSTRACTThis study was conducted to identify environmental and human health risks caused by Balarood Dam, in construction phrase. The first step, all risk-generating factors were identified using a Delphi Questionnaire. Afterwards, the identified criteria were prioritized once using the Analytical Hierarchy Process (AHP) method and then by the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Due to the complex and uncertain nature of decision-making in times of risk, it was necessary to use more than one weighting method to ensure accuracy of weights. The results from AHP and TOPSIS revealed a mismatch in priorities; therefore, an integration method was presented blending Mean-Rank, Borda, and Copeland methods. According to the TOPSIS results, factors including cut and fill, explosion, and transportation, were first to third highest-priority risk-generating factors, respectively. Considering the results from the AHP method, factors cut and fill, drilling, and explosion were iden...

Rapid land-use/land-cover changes in suburbs of metropolitan cities of Iran have recently caused serious environmental damages. Detection of these changes can be a very important step in urban planning and optimal use of natural resources. Accordingly, the present study was carried out to track land-use/land-cover (LULC) changes of Ahwaz County in southwestern Iran using remote sensing techniques over a period of 26 years, from 1987 to 2013. For this, ISODATA algorithm and Maximum Likelihood were initially used for unsupervised and supervised classifications of the satellite images. The accuracy of the LULC maps was checked by the Kappa Coefficient and the Overall Accuracy methods. As the final step, the LULC changes were detected using the cross-tabulation technique. The obtained results indicated that urban and agricultural areas have been increased about 57.5 and 84.5 %, respectively, from 1987 to 2013. Further, the area of poorly vegetated regions, in the same period, has been decreased to approximately 36 %. The largest land conversion area belongs to the poorly vegetated regions, which have been declined to about 10,371 and 1,334 ha during 1987–2007 and 2007–2013, respectively. Approximately 1,670 and 382 ha of the agricultural lands have also been changed to built-up areas by about 1,670 and 382 ha during the same periods. As a result, it was found that the northwest, southwest, and south of the county were highly subjected to urban development. This would be of great importance for urban planning decision-making faced by the planners of the city in the present and future.

The present study was carried out to evaluate agricultural capability of a watershed located in Khuzestan; a province in southern Iran. It is aimed to examine the applicability of Multi Criteria Decision-Making (MCDM) methods in site selection process. Accordingly, the ecological resources of the watershed were initially identified. To specify the criteria required for agricultural land evaluation, Delphi method was applied. After selecting the criteria, they were weighted using Analytical Hierarchy Process (AHP) Method. Weighted Overlay (WO) Method was also used to overlay the map layers in the GIS environment. Afterwards, sensitivity analysis was performed using Weights Sensitivity Analysis (WSA) method to show the impressibility rate of the results against a certain changes in the inputs. The results revealed that out of 6591.2 ha of the total watershed area, 50.8 % has unsuitable potentiality while 27.32 % has a poor suitability for irrigated agriculture. It was also determined that only 6.96 % of the whole study area has a suitable potential for this purpose. Besides, the findings indicated that 23.38 % of the total watershed area is unsuitable for rain-fed farming. the results also showed that 31.78 % and 19.12 % of the entire study area has moderate and high potentials for rain-fed agriculture, respectively. In a general overview, this study could present how MCDM is effective in handling land capability studies.

Protected areas are established to conserve unique features and biodiversity of the nature. Accordingly, wherever has one of the natural, ecological and/or cultural values it should be considered a protected area. Kave-Deh No-hunting Area is located on extremely east of Tehran Province in an area of 94,961 ha. Due to rich and diverse land cover, distinctive wildlife species, and unique monuments the area was selected as a case study to examine the possibility of its promotion to the protected area using Spatial Multi Criteria Evaluation (SMCE) Method. For this purpose, the relevant criteria were identified by Delphi method. After finalization of the most important criteria by Delphi panelists, the map layers were prepared at the scale of 1:100000, in the environment of GIS Software. Afterwards, the map layers were divided into factors and constraints of which factors were standardized by S-shaped membership functions of fuzzy logic. The dimensionless factor maps were weighted using Analytical Hierarchy Process (AHP) Method in the environment of Expert Choice Software. Subsequently, a mathematical equation was extracted to conduct the land suitability analysis. The Weighted Linear Combination (WLC) Method was applied to overlay the map layers and obtain the final ‘nature conservation’ land use map. The final land suitability map showed that 34,687 ha of whole study area (equal to 37 %) have the potentiality for promotion to the protected area.

This study aims to use integrated Shannon's Entropy–TOPSIS methodology for environmental risk assessment of the Helleh protected area in Iran. In this research, first, with regard to field visits, interview with natives of the area, and investigation of the environment of the study area, the risks existing in the region were identified. Then, for final identification of the risks, the Delphi method was applied. Analysis and prioritization of risks of the area of Helleh were performed by multi-criteria decision-making methods of Shannon's Entropy and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In this research, risks were assessed by three criteria of severity, probability of occurrence, and vulnerability. Twenty six of the risks were identified which were specified in two groups, natural events and environmental risks. The environmental ones were classified into four groups: physicochemical, biological, social–economic, and cultural. Results of the research showed that the construction of the Rayis-Ali-Delvari Dam at the upper part of the study area threatens the wetland. Water supply for the dam 75 km away from the area with concession of 0.9999 holds the first priority of risk-generating factors. Of the managerial workable solutions suggested controlling the risks, the stopping of the pumping of water from the wetland and observation of hunting season length and permissible type and number of hunting in the area can be mentioned.

The ninth olefin plan of Arya Sasol Petrochemical Company (A.S.P.C.) is regarded the largest gas Olefin Unit located on Pars Special Economic Energy Zone (P.S.E.E.Z). Considering the importance of the petrochemical unit, its environmental assessment seems necessary to identify and reduce potential hazards. For this purpose, after determining the scope of the study area, identification and measurement of the environmental parameters, environmental risk assessment of the unit was carried out using Environment Failure Mode and Effect Analysis (EFMEA). Using the noted method, sources causing environmental risks were identified, rated and prioritized. Beside, the impacts of the environmental aspects derived from the unit activities as well as their consequences were also analyzed. Furthermore, the identified impacts were prioritized based on Risk Priority Number (RPN) and severity level of the consequences imposed on the affected environment. After performing statistical calculations, it was found that the environmental aspects owing the risk priority number higher than 15 have a high level of risk. Results obtained from Low Density Polyethylene Unit revealed that the highest risk belongs to the emergency vent system with risk priority number equal to 48. It is occurred due to imperfect performance of the reactor safety system leading to the emissions of ethylene gas, particles, and radioactive steam as well as air and noise pollutions. Results derived from secondary assessment of the environmental aspects, through difference in calculated RPN and activities risk levels showed that employing modern methods and risk assessment are have remarkably reduced the severity of risk and consequently detracted the damages and losses incurred on the environment.

In the present research, combination of Indexing System Method with Analytical Hierarchy Process has been applied to assess the environmental risks of gas transfer pipe lines. By this process, classification and qualification of the numerous types of environmental risks would be accessible. Sum Index and Leak Impact Index indicate risk probability and risk severity, respectively. In this regard, total environmental risk is calculated based on multiplication of total risk probability in risk severity. Analytical hierarchy process is applied to evaluate the factors because of differences existed in the total effective level of these factors. For this purpose, Tasooj- Salmas gas transfer pipe line, 24 inch in size and 42 km in length was selected to study the environmental risks. Using geographical information system, investigated risks have been classified throughout the pipe line route. Results showed that 46 %, 48 %, 2 % and 4 % of the total studied pipe line is exposure to the high risk level (5467 – 6054), average risk level (6055 – 6641), low risk level (6642 – 7228) and very low risk level (> 7228), respectively. Vicinity of the southern part of the studied site with National park of Orumieh Lake is considered as the most vital ecological concern of this study. However, 15 km (18–33 of 220 km) of the total pipe line has been located at the 5 km from the considered biosphere reserve. Among the most crucial risk factors of the present project are Third Party Damage Potential, as well as natural potentials (Soil displacement).

The evaluation of land exploitation according to its capability is one of the most fundamental issues in sustainable development. For this purpose, selection of a suitable method is very crucial to consistent the results with fact. Hitherward different methods have been used for evaluation studies and talk about the effectiveness of each method.
