Taxation of pollutant emissions is one of the strategies recommended by economists to achieve some of the environmental objectives and eliminate contamination. The purpose of this study is to estimate the willingness to pay an environmental tax on gasoline. Method: In this study, a conditional valuation method (CVM) is used to measure individuals' willingness to pay for goods and services. The statistical population of this research is gasoline-fueled cars in Mashhad in 2017, due to the lack of information on the number of vehicles, the number of unlimited society has been considered. In this study, 500 people were selected by simple random sampling method. A researcher-made questionnaire was used to collect data. It’s validity was confirmed using content validity. Findings: The results indicate that 77 percent of all respondents tend to pay environmental taxes on urban air, while 22 percent of the population are not willing to pay any amount under the name of the pollution tax. Approximately 3% have not been self-reported regarding their willingness to pay. Discussion and Conclusion: Based on the research findings, environmental beliefs has a positive and significant effect on the willingness to pay tax on gasoline; therefore, it is suggested that cultural and informational platforms be developed before clarifying the need for environmental taxes before planning for such a tax.","PeriodicalId":15762,"journal":{"name":"Journal of Environmental Science and Technology","volume":"147 1","pages":"133-145"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91299644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of a tourism path construction, between Khalkhal county and Masouleh city, through the Shahrood tourist valley, this study seeks to identify the physical – spatial characteristics of the native housing of villages located along this valley, in order to preserve and apply it in future developments. \u0000Method: The research method is qualitative one and data analysis is done by descriptive-analytical method. After field studies in Shahrood valley villages, the study species have been selected in terms of the dominant features of the native architecture from the “Shal, Kolur, Derow, Asbu and Askastan” villages and analyzed. Physical-spatial characteristics, such as plan form, architectural elements, materials and methods of construction, roof form, openings ratio, the ratio of mass to space, and functional relationships, have been surveyed and analyzed. \u0000Findings: Dense rural fabric, extroverted and compact architectural form, small openings, porch and columnar Telaar, wooden torrehs, sloping roofs, regarding terrain slope and using local materials are the characteristics of the rural housing architecture in this region. Also in most species, the service space is located on the ground floor and the living space is on the first floor. \u0000Discussion and Conclusions: The results show that all studied species are extroverted, and have porch, Telaar and wooden torreh as the fixed and dominant elements. The species can be classified in two types: The houses with porch, having closet space and houses with porch, but without closet space.

Geographic data analysis is difficult without the use of geographic information and satellite data, and impossible in a complex case. In this study, potentials and barriers of physical development of the Ruodbar city using Remote Sensing and GIS be evaluated. Method: Firstly, in the ArcGIS software environment, using the AHP-FUZZY combination method the use of slope, gradient, land use, power lines, river, road and rail, fault and rural points are used to locate the urban sprawl. The output was extracted in the form of a map of AHP and fuzzy overlay into five groups with very good, good, moderate, weak and very weak potential. In order to expand the city's physical development by using a visual interpretation on Google Earth images for 2016, 2009, 2004 for 12 years, a map was drawn out as the result. Finally, the results obtained from the Geographic Information and Visual Interpretation System were compared. Findings: The findings of the AHP-FUZZY compilation show that 95.6% of the study area has very weak potential, 1. 52% has a weak potential, 1.17% has a moderate potential, 1.21% has good potential and 0.69% has a very good potential. And the findings from the visual interpretation method over the course of 12 years show that the development of the city is just Mehr Housing (a project done government). Discussion and Conclusion: Based on the findings of the AHP-FUZZY Compilation and Metrology Measurement, we concluded that most of the constructions have been implemented in unpredictable places in the city of Roodbar, which is influenced by natural and inevitable factors, including steep slope, abundant faults, permanent existence of Sefidrood river, and land use, most of which are gardens and forests and agricultural land and has prevented its physical development.","PeriodicalId":15762,"journal":{"name":"Journal of Environmental Science and Technology","volume":"116 1","pages":"225-235"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79179753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So one of the most important steps to achieve sustainable development is to carry out various environmental studies before implementing any development plan. \u0000Background and Purpose: In this study, with the aim of investigating capability and evaluation of spatial temporal variations in Yasuj, efforts have been made to implement weighted Linear Combination Technique in order to predict the capability of the region for urban development. Also satellite images were used to investigate the spatial temporal variation in Yasuj city. \u0000Analysis method: In order to investigate the amount of power and evaluation of temporal and spatial variation in urban development, the criteria and sub-criteria were determined based on experts' opinions and previous researches. Then the AHP technique assisted by 30 faculty members and experts was employed to paired comparison dimensions and criteria. After the paired comparison, the information layers were standardized in the Idrisi environment and in the GIS environment. Then the layers were combined to determine the land suitability for Urban development. Afterwards, in order to study the time-shift changes of land use in Yasuj city in the three periods of 1986, 2001, and 2016, Landsat satellite images, TM, ETM + and OLI sensors, which were prepared in the Envi 5.1 software environment, were used. \u0000Findings: Based on the land use change trends in the Yasuj area, residential or urban areas have undergone extensive changes that affected environment uses including forests, grassland, agriculture and aquatic structures. The forest, located inside and around the city of Yasuj, provides a lot of ecosystem services for the area, which by city development, these services have been reduced both quantitatively and qualitatively, which should be considered. \u0000Discussion and Conclusion: The results of this study can be used as a model for selecting suitable locations for urban development with respect to environmental considerations and results of this work shown that studies based on spatial data, especially on human settlements (due to their inherent nature) can be the basis for accurate planning.","PeriodicalId":15762,"journal":{"name":"Journal of Environmental Science and Technology","volume":"22 1","pages":"153-165"},"PeriodicalIF":0.0,"publicationDate":"2020-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88120217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
