Parvaresh, Hosein | Dehghani, Mohsen | Nohe-gar, Ahmad
Ecological capability evaluation and landuse planning can determine the best landuses and are important for the proper planning and sustainable development. There are various methods for ecological capability evaluation. In this research have been studied two methods (Land use planning method with Makhdoom ecological modsels) and (Geomorphology method) for ecological capability evaluation in Nesa watershed. This region is located in Hajiabad district of Homrmozgan Province. These methods have been compard. Results show that these two methods are relatively similar for this watershed and landuses for the most of this region are poor range management and conservation. According to Geomorphology method, 60% of this watershed is suitable for conservation and 50% of this watershed is suitable for poor range management, also according to Land use planning method method, 55% of this watershed is suitable for conservation and 47% of this watershed is suitable for poor range management. But preference of Land use planning method is determining of various landuses such as tourism, civil, rural and industrial development that helps to planner for the proper planning and management.

Ahmadi Foroushani, Seyed Mansour | Mahmoudi, Seyed Mohammad
Sixty-year history of Town and Country Planning in the world, raised a fundamental question: why following the successful models in the process of Town and Country Planning don’t have always similar results? Whether, the origin of differences and ambiguities are not in the boundaries, interrelation among the levels of decision making, policy making, uncontrollable democracy in land ownership, irrational use of land, programs instability and lack of appropriate development patterns, irrational zoning, or in a word in the execution of land administration? The principle aim of this research is to evaluate the role and importance of land administration in the realization of goals and programs to improve Town and Country Planning. In this study we have used mainly descriptive and analytical methods, we have found to the conclusion that the land administration is the most fundamental precondition for implement policies, plans and programs in Town and Country Planning, at the extend of territory. The experiences which has been obtained from the leading countries in the field of Town and Country Planning, also shows that land administration and its role is very important, because that, independent of the all way views and of the pre-determined policy, it depends, before anything, else on how to managing, planning and land use, as the most important actions and evolutions of the Town and Country Planning.

Mahmoudi, Seyed Mohammad
Many plans, programs and techniques of town and country planning has been used in an irregular and dispersed manner from the beginning of human apparition civilization up to modern times, without citing this concept. But based on the most specialists, the France was the first country which founded the scientific and academic paradigm of town and country planning in the world. Study and analysis of 50 years experiences in France can help efficiently the countries which are still at the beginning of this way or the countries that are in the very first stages. The main purpose of this article is to review and analyze the historical trend of the evaluations of town and country planning in France. In this research we have used historical case study method to describe and analyze the general status, plans, policies and programs that have been used up to now. The data has been collected by using different sources like official reports of DATAR in France and other books and articles in this area. At the end, based on a comparative study, we will try to give some suggestions for developing the town and country planning in Iran.

2023
Godarzi, Mohsen | Hajiani, Ebrahim
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.

Abedini, Mousa | Mohammadzadeh Shishehgaran, Maryam
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.

2023
Alizadeh, Shahnaz | Yamani, Mojtaba | Sarvati, Mohammadreza | Ghahroudi Tali, Manijeh
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.
اظهر المزيد [+] اقل [-]Territorial approach to rural development in Iran (A systematic review)
2023
Khodadadi, Ali | Pourtaheri, Mahdi | Tavakoli, Morteza
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.
