Ranking of Basic Elements for organizing of Rural Deteriorated Textures on Fringes of Metropolises Using ARAS Method (Case Study: Fringes of Tehran Metropolis)

Extended Abstract:

Introduction

Rural Deteriorated Texture (RDT) has lost its effectiveness in terms of form and content where the conceptualization of good rural form fosters movements, especially renovation (a part of the organization). This issue has been raised recently in the country, but many patterns are not proportional to reality, so intervention is needed to create a balance. Therefore, basic elements for organizing (renovation) of rural deteriorated textures (meaning five basic elements of rural form) include: building type; infrastructure; land use; density and layout. In this regard, scientific appraisal has not yet been for basic elements ranking the rural deteriorated textures. On the other hand, the Additive Ratio Assessment (ARAS) method has been introduced as a one of the most ranking methods recently. Therefore, the present study seeks to identify the most important elements of the RDT ranking using ARAS.



Methodology

The present research is based on library, documentary and field studies. This means that the most important indicators to identify basic elements for organizing (renovation) rural deteriorated textures were identified theoretically; and then, using questionnaires of 260 rural households and 15 local managers, 15 rural deteriorated textures on the fringes of Tehran metropolis were selected (using Kernel Density Estimation /KDE methods and GIS). Then ideas of fifteen elites and scientific experts (to 5 alternatives weighing) were analyzed. In this regard, firstly, the opinions of two groups of villagers (people and local managers) and scientific experts about the criteria (in order to emphasize planning with the people) was obtained using the Rank sum method and then ranked 5 alternatives (basic elements for organizing) was done using the ARAS method. In addition, SPSS and EXCEL were also used for further analysis.



Results and Discussion

The results obtained from the ARAS method showed that the building element form is a priority for organizing (renovation) of rural deteriorated textures. That follows by arrangement; layout; infrastructure; land use and; density form. In fact, the building form in organizing the rural deteriorated textures on the Tehran metropolitan fringe is more important than other elements because the role it plays.



Conclusion

The research findings indicate that the element- building form- is the most impotent compared to other elements for organizing rural deteriorated textures on the fringe of metropolises, using the ARAS method. However, the findings are not consistent with the results of other research and experiments, because researchers have not ranked the basic elements for organizing the rural deteriorated textures, which indicates the innovation of the present study. Since focusing on this leads us to a more accurate and desirable planning, researchers are encouraged to focus on this issue in the future research. However, the indexes of the element building form in the findings of this study are similar and consistent with other research and experience (directly or indirectly).

In general, the Rural Deteriorated Texture (RDT) has lost its effectiveness in terms of form, with more attention to the building element than others. In other words, more emphasis on the building strength index can achieve a sustainable rural form. Of course, this is an important part of organizing the rural deteriorated textures that is necessary for its various platforms/ aspects, with the participation of locals/ villagers (as main actors) and relevant organizations and institutions (public, private, NGOs as facilitators), which should be taken into account by future researchers
