Meta-analysis of the obstacles to the manifestation ofUrban regeneration projects in Iran

With the expansion of inefficient tissues, "Urban regeneration" has been objectified as a solution for developing cities in different physical, social and economic dimensions. Despite the development of the guidelines for urban regeneration projects, these projects in Iran still have challenges in the stage of realization and implementation. This article aims to identify the "challenges and causes of non-realization of urban regeneration projects in Iran" and analyse the research conducted in this field with a qualitative approach. For this purpose, a meta-analysis of 23 articles in the field of problems of urban regeneration projects in Iran was carried out. The challenges raised in the AtlasTI software were extracted with the help of open and axial coding. In the following, 100 codes were determined in the form of 10 groups or general categories. In the end, the obstacles to the realization of urban regeneration projects in Iran were given. According to the obtained results, the weak presence of non-governmental organizations, the problems of preparing plans, institutional and management problems, and the weakness of participation are the four most important and frequent challenges in the research related to the realization of urban regeneration projects in Iran
