Abstract

Historic urban areas are the beating heart of the city, but neglecting them can lead to low resilience. Therefore, paying attention to their regeneration can create a sustainable city. The purpose of this study was to determine the resilience of neighborhoods in Tehran and evaluate effective criteria for the resilience increase. In this study, to evaluate the resilience of Tehran, initially, 18 criteria were considered. Then, using the Delphi technique, 14 criteria among them were selected for final analysis. Using the AHP multi-criteria decision-making method, the importance of each criterion was determined. Using GIS capabilities, the parameters map was prepared, and by combining the prepared maps with AHP weights, a resilience map was created. Finally, 20 neighborhoods with the lowest resilience were identified as priorities for stabilization and regeneration measures, and the criteria status used in them was examined. Results showed that deteriorated urban areas (19.53%) and construction materials (18.51%) were the most important criteria. Non-resilience areas were generally in the southern half of the city. 78% of 20 selected neighborhoods had deteriorated urban areas, while only 14% of the city deteriorated. Finally, by examining the criteria in neighborhoods with the lowest resilience, suggestions were made to regeneration, sustainability, and increase the resilience of these neighborhoods.

Highlights

Nowadays, urban resilience has become one of the most important topics due to the center of human accumulation in the city and the impact of resilience on urban areas [1,2,3,4].The concept of resilience quickly found its place in the urban sustainability literature [5].Urban resilience is often associated with the terms of sustainability, smart city, regeneration, etc. [6,7].The word “resilience” is etymologically derived from the Latin word resilience, which means “to return, recoil” [8]
The purpose of this study is to rank the neighborhoods of Tehran in terms of resilience to determine the priority of regeneration using a combination of the Delphi and Analytic Hierarchy Process (AHP) methods and GIS capabilities
The results of this section will determine what the focus of the research is on the processing of which spatial data, based on which the resilience ranking is determined, and, the neighborhoods to be regeneration

Introduction

Urban resilience has become one of the most important topics due to the center of human accumulation in the city and the impact of resilience on urban areas [1,2,3,4].The concept of resilience quickly found its place in the urban sustainability literature [5].Urban resilience is often associated with the terms of sustainability, smart city, regeneration, etc. [6,7].The word “resilience” is etymologically derived from the Latin word resilience, which means “to return, recoil” [8]. The concept of resilience quickly found its place in the urban sustainability literature [5]. Urban resilience is often associated with the terms of sustainability, smart city, regeneration, etc. The word “resilience” is etymologically derived from the Latin word resilience, which means “to return, recoil” [8]. Resilience in the dictionary is the ability to return to the original state after a stressful and unusual situation [9]. The concept of resilience originates from ecology and refers to “a measure of the durability of systems and their ability to maintain stability in the face of change and turbulence and to maintain the same relationship between population or state variables” [10,11]
