Dou to the special importance of land use in Iran and the passage of over one year from the enactment and communication of National Land Use Document in March 2020 and the concerns about the practical steps to implement the provisions of National Land Use Document by executive organizations, the main question of this study is that in the light of the roles of related actors, how will this document be implemented? The research methodology of this study was actor-oriented, and the project was carried out based on exploratory and expert-based methods. Data were collected from 23 experts of Iran’s land use domain using a questionnaire. The data was analyzed using MACTOR futurology software. The results showed that from among the initial 33 effective actors in the Document implementation, 13 actors were selected as the main actors by the expert panel. It was observed that so far, no strong will has existed in those main actors to implement the National Land Use Document, and they don’t seem to be motivated to so in near future. In other words, the Document content and the potential of supervisory organizations are not so mandatory to force the main actors responsible for the implementation of the Document to put it into practice. Therefore, it is predicted that in future, the implementation of the Document will face serious challenges from institutions and actors. It is necessary for the responsible institutions (Planning and Budget Organization as well as Supreme Council of Land Use) to seriously follow up, make effective communications, bring about strong institutional combabilities among actors, and ask all implementing organizations to work in order to pave the ground for the formation of national will to implement the National Land Use Document as soon as  possible.

Urbanism in the world has had a great role in the formation of the concept of urban area. A high ratio of urban population resides in metropolitan areas, and the advancement of transportation and HSR network has changed the concept and dimensions of urban areas. As most of the analyses of urban area development through HSR has been limited to economic studies, this study set out to pay attention to the geographical concept of area and the effects of HSR as a strong policymaking tool in use. In this article, the systematic literature review based on keywords was used to extract the related articles from the most authoritative scientific websites, and then based on the evaluation of abstract, methods, and results sections of the articles, 75 papers published between 1938 to 2022 were selected as the sample. Then, attention was paid to the background and process of the evolution of attitudes and conceptualizations of urban area from the beginning till now. The metropolitan area is discussed based on analytical and normative approach at urban, regional, national, and global levels. With the connection of metropolitan centers to high speed access networks, polycentric development occurs. High speed rail (HSR) has the potential to help evolve the urban network, bring about urban area integrity, and develop new centers. The conceptual explanation of the strategy of creating polycentric metropolitan areas through the expansion of HSR can help expand the connect metropolitan areas, enhance integrity, create specialized cities, creatively use space organization plans, and solve part of the developmental issues.

As the main source of energy, the sun is the origin of life and the root of every other known energy. The global radiation of sun is one of the fundamental structures of any climatic range. Thus, knowing the qualities and predicting these fundamental structures have a great effect on energy-based plannings. The use of satellite images and remote sensing models have been used as suitable and cheap means to estimate solar radiation. In this study, the 2020 year images of Landsat 8 satellite, OLI sensor, TIRS sensor, and SEBAL algorithm were used.   ENVI software was used to make geometric, atmospheric, and radiometric modifications of the satellite images and execute SEBAL model calculations, and ArcGIS was used to create database, conduct locative analyses, carry out cartographic operations, and implement the model. The obtained results showed that the average of highest short-wave incoming radiation has been 862 watts per square meter on August 9, 2020, and the lowest value has been 368 watts per square meter on October 28, 2020. Nonetheless, the highest absolute radiation value has been 901 kilometers on June 6, 2020, and the lowest value has been 19 kilometers on September 10, 2020.  The difference in the absolute radiation values received by earth in the area under study is due to the difference in the sun’s radiation angle and the number of sunny hours in different months of the year. Finally, it can be concluded that the solar radiation in the region in the year under study has the potential to execute solar photovoltaic plans.

Neglecting coastal erosion and its changes can lead to environmental hazards, which are among the main factors affecting human communities and facilities. Paleontological research demonstrates tens of meters of fluctuation in the water level of the Caspian Sea. The shores of the Caspian Sea have variable topography and land use, including lowlands (estuaries of rivers, gulfs, and progradation) and sandy uplands. In lowlands, there is a slight slope that causes flooding of lands when the sea level rises, as well as an increased piezometric level of coastal aquifers. This study investigates changes in the coastal line from Talesh to Anzali over a period of 45 years using spatiotemporal analysis in the form of coastal cells. For this purpose, ArcGIS software was used to extract the coastal lines of 1975, 1997, and 2020. Then, using DSAS software, the amount of changes in the coastline was determined. The research results showed that changes in the coastal line in the study area were entirely influenced by the fluctuations of the Caspian Sea level, with 77% of the coastal line experiencing more than 30 meters of retreat. Human activities have somewhat prevented the instability of the coastline due to changes in the water level of the Caspian Sea.

Many years have passed since the initiation and implementation of sustainable rural development projects in the country of Iran, however, rural communities in many regions of the country still face numerous challenges. In this regard, government planners and administrators have made efforts to address the issues and problems of rural areas by presenting new approaches. Accordingly, the current research aims to provide a different approach to rural development by critically and comparatively analyzing traditional approaches in rural development planning. Therefore, the present research is of a developmental type, and the research method is analytical-interpretive, with data collection primarily based on library and documentary research. The findings of the study indicate that the top-down approach based on the endogenous approach and sectoral planning still dominates the rural development system in Iran, and as a result, the desired development of rural communities nationwide has not been achieved. The results show that sustainable rural development can be facilitated at the national level by incorporating the characteristics of a territorial approach. This suggests that a proposal beyond agriculture should be based on the participation of all stakeholders, emphasizing the importance of social factors and rural institutions, and incorporating both agricultural and non-agricultural occupations, considering the interrelationships between agricultural, industrial, and service sectors, and most importantly, it should be inconsistent with a spatial perspective on urban-rural relations. Therefore, the process of rural development in the country would be economically rational, socially equitable, and environmentally responsible.

Locating and architectural design, as a suitable platform to provide the ground for achieving the goals and purposes of passive defense, is of great importance and causes the success of decision-making at different strategic levels. Office spaces are one of the uses that are considered by planners and designers for urban services. The current research is among applied research and descriptive-analytical research methods and it aims to locate and design office sites in Isfahan City. Documentary methods and questionnaires were also used to collect information. For this purpose, 18 indicators for the location of urban administrative uses in the form of four general criteria (demographic, functional, physical, and structural), selected and using the network analysis process model (ANP), the importance coefficient of criteria and sub-criteria are determined. The coefficients obtained in the environment of the geographic information system (GIS) were influenced by the information layers. By overlapping them, areas prone to the construction of office uses have been identified. Then, each of the eighteen uses was weighted using the Delphi method and experts' questionnaire. Finally, using the capabilities of the geographic information system (Euclidean Distance and Weighted Overlay), the spatial distribution of each service use was analyzed. The results of the research show that 3% of the entire city of Isfahan has very low desirability, 15.9% is low desirability, 43.4% is moderate desirability, 28.74% is high desirability and 8.96% is very high desirability. From the south to the north of the city, the level of desirability decreases.

Considering the fact that the supply and demand of ecosystem services may be geographically different, therefore, the management of this spatial heterogeneity requires the evaluation and zoning of ecosystem services in the form of spatial maps. Accordingly, in the present study, the spatial distribution of ecosystem services in the mangrove forests of Khamir and Qeshm was evaluated and zoned. According to the results in this area, cultural services have the most points among the available services due to the high entertainment value. Therefore, among the examined criteria, leisure and nature tourism have more demand for spending leisure time and tourism due to its pristine landscapes, aesthetic values, education, recreation, etc. Likewise, among provisioning ‎ecosystem services, traditional fishing (Moshta) is scattered in most areas of this region within the main tributaries and estuaries and has the largest supply in the area.  This ecosystem service is important among the residents of the area, the reasons for which are the livelihood and economic dependence of the local people on this service. Finally, the prioritization of ecosystem services distribution in the studied areas demonstrated that the most services offered and with the highest priority in the area are related to cultural services. In this service, the highest priority is also given to the standard of recreation and nature tourism on the high class, and other services, including aesthetics, sense of place, heritage value, spiritual and religious value, education, and inspiration, are placed in the next priorities. Accordingly, zones that have a high density of mangrove habitats also have a high supply of cultural services. Therefore, examining the spatial distribution of ecosystem services through the evaluation and zoning of these valuable resources can help to correct the plan and protection of natural ecosystems to meet human needs.

The present research has been carried out with the aim of identifying the challenges of tourism in Soleqan village during the Coronavirus pandemic with an analytical approach it is functional and it has been done using qualitative paradigm and exploratory theory method. The research community is made up of tourism experts and specialists from different rural areas and 15 of them were selected by using the combined purposeful sampling method. The data collection method was done using library studies, interview protocol, and direct observation and continued until reaching the theoretical saturation level. Data analysis was performed using coding. The collected data were analyzed through content analysis. The results of the research show that the most important challenges caused by the pandemic in Soleqan village are: not being used, remaining unknown and destroying the human, natural, and cultural capacities of villages, paying less attention to the native and local attractions of the villages, economic recession (poverty and unemployment), the inefficiency of the policy process, planning and lack of government and local support.

Inevitably, inconsideration of the population evacuation of villages can have irreparable consequences for the human settlements. Analysis and identification of the qualities of this issue can greatly help planners and decisionmakers in the spatial planning domain to prevent full evacuation of population from rural settlements. The study at hand was an applied research project done using descriptive-analytical approach. The statistical population comprised of villages with less than 100 residents in Khorasan Razavi province from 1986 to 2016. Moran’s local spatial analysis was used to investigate the spatial dimensions, and arithmetic mean and skewed distribution were used to examine the direction and range of distribution. The results showed that in the 1986, 1996, 2006, and 2016 censuses, 92.2, 90.1, 94.8, and 79.9 percent of the villages evacuated in the previous decade have had lower than 100 residents. The results of Moran’s spatial autocorrelation analysis demonstrated that the distribution pattern of villages on the threshold of evacuation during these three decades is cluster-like. Moreover, the results of arithmetic mean and skewed distribution indicated that 68 percent of the villages that are on the threshold of population evacuation are within the oval domain, and except for the 1986-1996 period – when the distribution direction of villages on the threshold of evacuation has been northwest-southeast, the direct has been northeast-southwest from 1996 to 2016.

Water provision service is one of the most valuable ecosystem services that is important as a key service for the healthfulness and management of water resources. In this study, using the Water Yield model of InVEST software, the water supply and demand in Ilam watershed was modeled. The data related to average annual precipitation, annual evaporation and transpiration, root limiting depth, water available for plants,  land use map, water consumption and estimation of water provision quantity, basin boundary, and subbasins of the watershed were the inputs of this model. The results of model application showed that in Ilam watershed, 45 million cubic meters of water provided annually, with the highest and lowest water provision volumes being in Arghavan (7 million cubic meters) and Chalimar (802 thousand cubic meters) subbasins, respectively. According to results, there are great differences in the water supply and demand in the subbasins of this watershed. Therefore, planner and policymakers should pay attention to this important issue in the layout of land uses and foresee sustainable use of rich forests in the high yield subbasins such as Arghavan subbasin. The results provided in this study, along with showing the importance of modeling surface water demand and its used in macro-policies of water allocation, can function as a guideline and help the managers and planners of Ilam city to adopt reasonable decisions in managing ecosystem and correctly using land in this area.
