    Background

    Tourism as a vital economic sector necessitates infrastructure development. Within this context, provision of tourist accommodation stands out as a crucial service for sectoral growth, requiring optimal siting based on diverse regional indicators and capacities.

    Purpose

    This study aimed to identify potential areas for establishing tourist accommodation in Dezpart Region in Khuzestan Province. Additionally, it conducted a comparative analysis of fuzzy overlay models to assess their respective outcomes.

    Research Method

    The research employed a descriptive-analytical approach based on spatial data. Fuzzy logic analysis was conducted using ArcGIS software, involving data standardization, fuzzification using established algorithms, and application of the Analytic Hierarchy Process (AHP) model to derive criteria weights. The fuzzy overlay methods were then utilized to generate the final map.

    Findings

    The results indicated that, among the 9 criteria examined, the distance from tourism sources (with a final weight of 0.290) and the distance from fault lines (with a weight of 0.192) were the most influential in identifying areas suitable for tourist accommodation. Furthermore, analysis of the fuzzy overlay models confirmed that the Gamma model was more stringent and pessimistic compared to the Sum model. According to the Sum fuzzy model, over 39.41% of the area was deemed suitable, whereas the Gamma model identified only 10.3% as suitable for accommodating tourism services. The overall quality assessment also supported the superiority of the Sum model in delineating potential areas for tourist accommodation. Examination of the spatial distribution of the final maps revealed a greater concentration of suitable areas in the central and northern regions.

    Introduction

    Establishment of tourist accommodation facilities at the regional level is an indisputably significant matter. However, determining the optimal siting of these services necessitates the utilization of various methods and amalgamation of diverse criteria, a task well-suited for the capabilities of a Geographic Information System (GIS) environment. Dezpart Region in Khuzestan Province, which was designated as a new city in 1401, possessed multifaceted potential for tourism development, alongside its agricultural sector. The region boasts a rich array of tourism resources and attractions, encompassing historical, natural, rural, and cultural elements and thus underscoring the imperative for strategic planning in this area. A pivotal aspect of this planning involves identifying the most suitable locations for establishing tourist accommodation centers. This endeavor not only contributes to the fundamental advancement of tourism, but also aids in attracting tourists over the medium and long terms. Consequently, this research aimed to identify potential areas for establishing tourist accommodation in Dezpart Region in Khuzestan Province, while also conducting a comparative assessment of fuzzy overlay models to discern the most effective approach. 

    Materials & Methods

    The research methodology employed in this study was descriptive-analytical and practical in nature. Data collection and analysis were conducted using documentary and organizational methods. The primary data utilized for map preparation consisted of the spatial data obtained from the country's mapping organization. To process the spatial data, operations, such as equalization, data formatting, ground referencing, and data adaptation, were performed. The criteria considered in this research encompassed elevation, slope, land use, distance from communication roads, distance from urban and rural settlements, proximity to tourism attractions, proximity to water sources (rivers), and distance from fault lines. Subsequently, the data underwent standardization and fuzzy logic analysis within the ArcGIS software. Weighting the criteria was done by using Expert Choice software and the Analytic Hierarchy Process (AHP) method. Consequently, the weights of the influential criteria for locating tourist accommodation centers were established. Finally, employing various fuzzy models or operators, including Gamma and Sum, a map was generated to identify potential areas for establishing accommodation-tourism centers. 

    Research Findings

    In this study, the criteria of distance from communication roads, rural and urban settlements, and proximity to tourism sources were assigned a value and membership of 1 for locations with shorter distances. This was because, for instance, closer proximity to communication roads or tourism resources signified greater suitability for accommodation-tourism services, making closer areas more pertinent for the research objective. A linear function was employed to fuzzify the map for these criteria.Utilizing the Gaussian function, a threshold limit was established such that any deviation beyond this threshold, whether an increase or decrease, would result in a value of zero for the areas or locations. For instance, a threshold limit of 3 km was set to assess the distance from water sources with values approaching zero for deviations from this threshold.Additionally, a small function was utilized to fuzzify the elevation and slope criteria with respective threshold limits of 1700 m and 25%. Consequently, areas with lower slope or elevation were assigned a membership grade of 1. Conversely, a large function was employed to fuzzify the distance from fault lines (with a threshold limit of 10 km) and land use (with a threshold limit of 4), resulting in areas with greater distance or value being assigned a membership grade of 1, thus denoting their suitability.The results revealed that among the 9 criteria examined, the distance from tourism sources (with a final weight of 0.290) and the distance from fault lines (with a weight of 0.192) were the most influential in identifying areas suitable for accommodation-tourism services. A comparison of the proposed maps indicated that the Sum overlay method identified more potential areas for accommodation-tourism services in the region compared to the Gamma method. Furthermore, the Sum method encompassed the central, western, and eastern areas, while the Gamma method suggested a narrow line in the central area for tourist accommodation. Notably, the proposed area deemed highly suitable for creating accommodation-tourism places covering 39.27 km2, which was equivalent to over 3.10% of the region's area, in the Gamma overlay method. In contrast, the Sum method identified 499.72 km2, representing 39.41% of the region's area as highly suitable for accommodation-tourism services. 

    Discussion of Results & Conclusion

    Analyses of the fuzzy overlay models revealed that the Gamma model was more stringent and pessimistic compared to the Sum model. According to the Sum fuzzy model, over 39.41% of the area was deemed suitable for creating accommodation-tourism services, whereas the Gamma model identified only 10.3% as suitable. The overall quality assessment also confirmed the superiority of the Sum model in delineating potential areas for accommodation-tourism services. Examination of the spatial distribution of the final maps further indicated that the susceptible areas were more prevalent in the central and northern geographical regions.

    Background

    The rapid growth of global population and urbanization has resulted in disorder in urban spaces, diminishing their effectiveness and exacerbating transportation issues. Furthermore, the lack of foresight by urban managers in long-term planning has hindered sustainable urban development. Consequently, policymakers and urban planners have been compelled to address these challenges through appropriate measures and strategies. The Transit-Oriented Development (TOD) approach has been presented as a viable solution to these disruptions. This approach aims to revitalize surrounding land uses and improve the movement of goods and services by making adjustments in the vicinity of public transportation systems. The metro station of Meydan Sā'at (Line 1) in the two-municipality area of Tabriz City holds significant potential to evolve into a TOD center due to its numerous challenges.

    Objective

    The research endeavored to foster sustainable development, cultivate a welcoming environment, and restructure land use in accordance with TOD criteria.Research

    Method

    The methodology employed was descriptive-analytical with practical objectives and the research was conducted through the preparation of a questionnaire, data extraction from GIS software, and the use of the Analytic Hierarchy Process (AHP).

    Findings

    Upon analyzing 4 primary criteria and 9 influential sub-criteria, the results underscored the significance of options, such as enhancing economic efficiency, improving the public transportation system's effectiveness, and increasing density with the selection priority scores of 0.25, 0.183, and 0.161, respectively.

    Introduction

    Contemporary urban transportation system design involves formulating comprehensive urban plans to maximize the alignment between urban development policies and the need to reevaluate land use in accordance with urban network characteristics. Coordinated and simultaneous planning for transportation and other influential urban factors, such as land use and density, can reduce citizens' time and cost in utilizing urban spaces to fulfill their needs. However, the lack of attention to this issue and continuation of separate planning for individual elements hinder the achievement of an optimal city shape and structure, particularly given the escalating population and traffic trends in cities. This situation leads to increased costs for citizens to access different parts of the city and transforms traffic problems into formidable challenges for city managers. Consequently, utilization and spatial distribution of urban lands play a crucial role in optimizing urban space usage. In general, defining land use encompasses various types of land use, density, land use per parcel, building height, architectural appearance, and integration of commercial, residential, and healthcare facilities within each neighborhood. In response to emerging urban issues, such as traffic congestion, air pollution, and haphazard city expansion, Transit-Oriented Development (TOD) has been proposed as an advanced perspective. Sustainable development, through the interconnectedness of transportation and urban development within the framework of smart growth and new urbanism movements, emphasizes public transportation to foster healthier societies and a more dynamic economy. By integrating transportation planning and land use, this approach aims to curb the scattered expansion of physical development and marginalization of cities. 

    Materials & Methods

    In line with the research objectives, a descriptive-analytical research method based on document analysis and library studies was employed with a practical orientation. Consequently, data collection involved a synthesis of global experiences, the structure and principles of Transit-Oriented Development (TOD), and the information extracted from GIS software to elucidate the research theoretical foundations. Field observations were also conducted to gather the necessary data and information within the study scope. The Analytical Hierarchy Process (AHP) technique and Expert Choice software were utilized to analyze and evaluate the data derived from the completed field reports. In this context, the criteria and sub-criteria for regenerating the land use of Meydan Sā'at Station (Line 1) were selected based on an investigation of the study area and relevant fundamentals. Subsequently, expert opinions were incorporated through the creation of questionnaires to facilitate pairwise comparisons.

    Research Findings

    Evaluation of the sub-criteria revealed that "increasing economic efficiency" held the highest importance with a score of 0.232 in the economic criterion followed by "increasing the efficiency of the public transportation system" at 0.183 in the traffic criterion and "increasing density" at 0.161 in the economic criterion. Consequently, revisions were made based on the priority of the criteria and sub-criteria. Conversely, "increasing social interactions" scored 0.058 in the social criterion, "expansion of green space" scored 0.044 in the environmental criterion, and "increasing the safety of pedestrians" scored 0.064 in the traffic criterion indicated their relatively minor roles in achieving the research goals. Additionally, "increasing public services" scored 0.095 in the economic criterion, "expanding green space" scored 0.044 in the environmental criterion, "reducing biological pollution" scored 0.077 in the environmental criterion, and "reducing parking" scored 0.086 in the traffic criteria were identified as next in priority. 

    Discussion of Results & Conclusion

    Successful development of Transit-Oriented Developments (TODs) hinges on the convergence of numerous intricate factors, including social conditions, demographics, economic conditions, political support, and promotion of alternative transportation among others. However, without a solid foundation, these factors become inconsequential. Therefore, the researchers’ objective in this study, based on the conducted research and theoretical concepts, was to assess the influential elements in integrating the efficiency of public transportation systems and land use according to TOD criteria with a focus on land use intensification within a city. To this end, analysis, evaluation, and prioritization of the research criteria and sub-criteria were conducted by using the Analytical Hierarchy Process (AHP) technique and Expert Choice software. The results obtained from the AHP technique indicated that the "economic," "social," and "environmental" criteria held the weights of 0.48, 0.27, and 0.15, respectively. Furthermore, the sub-criteria of "increasing economic efficiency," "enhancing transportation system efficiency," and "general transportation" followed by "increasing density" emerged as the most significant factors with the respective weights of 0.232, 0.183, and 0.161. These findings aligned with the results of previous studies by Rafiyan et al. (2011), Saatian et al. (2010), Faramarzi Asli et al. (2021), and Mirfatahi et al. (2021).

    Overexploitation of natural resources and the environment during urban development has led to numerous environmental challenges in cities. This study aimed to identify the key criteria for establishing sponge eco-city pavements using environmental technologies and assess the importance and performance of these criteria in Shiraz. The research adopted an applied approach and utilized a descriptive survey method to analyze the importance-performance of environmental technology components in sponge eco-city pavements. Initially, a Delphi study was conducted, involving 30 expert panel members selected through a snowball sampling method. Following multiple sessions, the criteria with the highest scores were identified through an importance-performance analysis. The findings revealed that permeability and cost-effectiveness were the most and least important criteria with values of 3.78 and 3.30, respectively. In terms of performance, load bearing capacity and water storage capacity scored the highest and lowest with values of 3.16 and 3.04, respectively. The importance-performance matrix positioned permeability and water storage capacity in the 1st quarter, stability and load bearing capacity in the 2nd quarter, strengthening the underground ecosystem in the 3rd quarter, and affordability in the 4th quarter. Ultimately, the study emphasized the prioritization of permeability and water storage capacity, which held the highest weights of 2.646 and 2.442, respectively. thus, they should receive primary attention in the development of pavements in Shiraz.

    Introduction

    Rapid urbanization, unplanned urban development, and recent climate changes have had detrimental effects on human settlements and the environment. Consequently, adoption of environmental technologies to achieve a balance between environmental protection and mitigation of the adverse impacts of development has gained significant global importance in creating sustainable societies. In response to water challenges and environmental degradation, the concept of the sponge eco-city initially proposed in China holds promise in addressing environmental issues, enhancing human well-being, fostering growth and development, and achieving sustainability within communities. The sponge eco-city emphasizes the integration of environmental considerations into all physical structures within urban spaces, aiming to harmonize city development with the natural environment and advance the principle of sustainability by aligning human and ecological processes in urban settings. In light of this, the present research endeavored to analyze the importance-performance of fundamental environmental technology components in the pavements of the sponge city of Shiraz with an ecological approach. 

    Methodology

    This study focused on Shiraz, a prominent city in Iran and the capital of Fars Province. It was an applied research with a descriptive nature, employing a survey method through a questionnaire. The documentary section involved gathering theoretical data related to environmental biotechnology, urban ecological approach, sponge city, etc., from articles, books, statistical reports, and relevant documents. In the field section, a questionnaire was used to collect additional data. The Delphi panel comprised 30 experts, including professors specializing in urban planning and management, crisis management, natural resources, and urban environment. They were selected through the snowball sampling method. The identified criteria were presented to the expert panel. Following multiple sessions, the criteria with the highest scores were analyzed using the importance-performance analysis method. 

    Research Findings

    The study revealed that the permeability component held the highest importance with a value of 3.78, while the cost-effectiveness component had the lowest importance at 3.30. Regarding performance, the load-bearing capacity component scored the highest at 3.16, whereas the water storage capacity component had the lowest score at 3.04. Additionally, the positioning of each component in the importance-performance matrix indicated that the components of permeability and water storage capacity were situated in the 1st quadrant, signifying high importance but low performance. This presented a significant weakness in Shiraz City system, necessitating immediate attention and implementation of improvement strategies. Sustainability and load-bearing capacity positioned in the 2nd quadrant demonstrated desirable performance in these areas and recommended maintaining and preserving this situation. The component of underground ecosystem enhancement fell in the 3rd quadrant, indicating low importance and low performance and suggesting a relatively negligible role in the system's efficiency and resilience. The component of cost-effectiveness placed in the 4th quadrant, represented nonessential strengths that could be better utilized by reallocating resources to strengthen other components. Ultimately, based on the weighted prioritization, permeability and water storage capacity with the highest values of respectively 2.646 and 2.442 had to be earnestly considered as fundamental priorities for improving the pavement system in Shiraz City.

    Discussion of Results and Conclusion

    The findings suggested that the pavements in Shiraz should be constructed or reconstructed based on the principles of sponge eco-city structures. This type of pavement allows rainwater to be stored in the lower layers during rainy days and released as water vapor on sunny days. Essentially, rainwater is stored in an underlying sand layer, creating favorable conditions for the growth of tree roots and microorganisms and leading to the decomposition of absorbed pollutants and enrichment of the ecological system with nutrients, thereby promoting flourishing and diversification of the underground ecosystem and urban biology. Permeable pavement presents a viable alternative to traditional impervious pavements, mitigating adverse environmental impacts across various city areas. Rapid urbanization and unplanned urban development in Shiraz have altered land use patterns, leading to conversion of land into urban construction, expansion of roads, increased impervious surfaces, loss of valuable environmental resources, diminished agricultural lands, reduced and polluted water resources, intensified heat island effect, habitat destruction, and decreased biodiversity. Consequently, decision-making institutions, planners, and urban managers in Shiraz should prioritize the sponge eco-city approach in future development plans as a necessity to address the myriad challenges of urbanization and achieve sustainable development goals.

    Housing is a fundamental component in fulfilling the biological, economic, and social requirements of every household. The rapid urbanization, burgeoning urban populations, rural-to-urban migration, degradation and demolition of aging structures, diminishing household sizes, and housing supply challenges are prevalent issues in many cities, particularly in developing nations, such as Iran and India. This study focused on the housing exchange values in the 10th district of Tehran. The research was purpose-driven and employed a descriptive-analytical approach with a quantitative methodology. Regression and Moran methods were utilized for the investigation with housing prices for villas and apartments as dependent variables and 14 indicators as independent research variables. Spatial analysis was conducted using ArcGIS software. The results of the multivariate regression analysis indicated that household income had a direct impact of 17% among economic factors, while density had a direct effect of 77% among social factors. Additionally, structure age and type accounted for 63% and 31% of the most significant negative impact on housing price fluctuations in the 10th district of Tehran, respectively. Access to medical facilities had the most adverse effect on housing prices in the southern part of District 10, whereas access to commercial centers had the most substantial direct impact on housing exchange values in the district. Consequently, the highest concentration of hot spots indicating the highest housing exchange was observed in the northern and central parts of the 10th district of Tehran.

    Introduction

    In recent years, the housing sector of Iran as a developing country has experienced significant fluctuations, resulting in widespread adverse effects on households, other economic sectors, and even the banking system. Consequently, the impact of monetary policy on the performance of housing market has become a primary concern for policymakers, necessitating appropriate responses from monetary and financial authorities due to the sector's pivotal role in the country. Housing and its market have been the subject of extensive urban studies, particularly in urban economics, over the past 4 decades. The municipality of District 10 of Tehran has undergone rapid physical and economic expansion in the last two decades accompanied by increased investment in construction. Urban management initiatives have further exacerbated this situation, leading to unbalanced spatial developments at the regional level. Weaknesses in the housing sector within the municipality of the 10th district of Tehran include the housing supply-demand gap, particularly among low-income groups, a high number of households requiring assistance, a low proportion of durable residential units, a high prevalence of non-professional constructions, and the greater profitability of land transactions compared to housing construction. Additionally, there has been a surge in trading activities, a disproportionate increase in land prices compared to construction, and an intensified expansion in recent years. Therefore, this research conducted a spatial analysis of urban housing exchange values over a 1-year period (2022). By examining the spatial analysis of housing prices and exchange values, variations in income, culture, urban infrastructures, and perceived social and environmental comfort across different areas and localities could be observed. Consequently, the findings of this study could offer valuable insights for urban planners, managers, and housing investors. 

    Materials and Methods

    This study was applied in its purpose and employed a descriptive-analytical method using a quantitative approach. Multivariable regression analysis was utilized to explore the relationship between factors influencing the exchange value of housing from both consumer and producer perspectives, identifying key determinants affecting housing prices. The research findings were presented through descriptive tables, explanatory tables, and numerous maps created by the researcher. The results highlighted the components and factors with the greatest and least impact on the land and housing market in the neighborhoods of District 10 of Tehran. The study drew on documentary sources, statistical data, censuses, official information from relevant organizations, internal and external information databases, as well as comprehensive and detailed urban development maps and plans to collect theoretical foundations and extract data. Given the significance of direct observation in geographical research, the researchers’ observational method and familiarity with the study area served as the primary research tools supplemented by a researcher-designed questionnaire. The questionnaire primarily focused on gathering land and housing prices from real estate consultants for 2022. The research methodology integrated both quantitative and qualitative approaches. The theoretical framework was developed based on the subject under study and the study employed statistical description and analysis, image processing, and analysis using spatial databases and geographic information systems. Additionally, Excel, SPSS, and ArcGIS software were utilized for data preparation and processing. 

    Research Findings

    One of the most notable and distinctive aspects of this study in comparison to others was the spatial analysis of housing prices in District 10. This involved the integration of geographic information system software and quantitative models, such as hot and cold spot models, Moran, Vansim, and vector map conversion to raster. These were recalculated at the level of study units (statistical blocks of the 10th district of Tehran) revealing the spatial analysis of independent (economic, social, and physical) variables. Despite the highest density of apartment buildings being in the neighborhoods of Hashemi, South Karun, South Salisbil, and North Salisbil in Tehran's 10th district, it appeared that the value of multi-story buildings in the neighborhood of South Zanjan was more influenced by land prices, household income, and employment rates. Three spatial autocorrelation patterns (clustered, scattered, and random) were observed with Moran's coefficient indicating a clustered pattern in relation to the price of villa buildings at the level of North Salisbil, South Karun, and South Karun localities. The economic factors influencing housing prices in 2022 at the level of residential blocks in Tehran's 10th district included land prices, household income, mortgages, and rents. The regression analysis conducted in Excel software revealed a 0.64% correlation between economic indicators and housing prices. The highest correlation between socio-cultural indicators and housing prices in the southern areas of Tehran's 10th district was observed in Imam Khomeini, Hashemi, Karoun, and Kimel streets, the beginning of Nematullah Shah Parori Street, and the end of Malik Ashtar Street. According to Moran's spatial autocorrelation model, the coefficient for the correlation of the indicators of access to uses and services and housing prices was 0.050658%. The highest correlation to all factors was observed in District 10 (north of the region) corresponding to Karun and North Salisbil localities. Access to urban services, military uses, and facilities like airport had led to a significant decrease in prices, while access to commercial, medical, and educational centers had a positive effect on increasing housing prices. 

    Discussion of Results & Conclusion

    Housing stands as a fundamental necessity within any society and fluctuations within this sector exert a profound impact on the broader economy. Therefore, precise forecasting of housing prices holds significant importance for homeowners, investors, and other stakeholders in the housing sector. The presence of a reliable method for predicting housing prices can enhance efficiency of the housing market. The surge in urban population over recent decades coupled with limited access to resources, services, and essential infrastructure has transformed housing into a scarce and invaluable commodity. The housing predicament is a consequence of the industrial revolution and subsequent developments leading to a detachment of its exchange value from its consumption value. Its significance has continued to escalate across diverse societies. This study leveraged spatial descriptions and analyses available in geographic information systems (ArcGIS software) complemented by statistical analyses conducted using Excel and SPSS software.
