A Look at the Development of Endogenous Urban Decayed Texture (with Emphasis on Revitalization, Improvement, Renovation, Reconstruction) and its Challenges

Cities, as living beings, are always going through a cycle of physical life in the course of their evolutionary development; they are born, grow, increase in quantity, become vaster and take new roles, become old and suffer from erosion. Meanwhile, humans, in order to preserve the identity and authenticity of the city, and to realize the sustainability and survival of the city and its fabric and especially decayed fabric, takes measures, one of which is that of urban endogenous development. The term " endogenous development" is, based on its own definition, renovation, improvement, and, in other words, making existing urban areas usable again, which is usually done in areas that have lost their integrity and are on the way to collapse. In fact, the city's endogenous development is the optimal use of the potential of the city and a new vision of life in the city, especially the decayed fabric. The purpose of this paper is to investigate ways to achieve endogenous development of decayed fabric through regeneration, renovation, reconstruction, as well as barriers on its way. In this paper, through a descriptive and analytical approach and by documentary method, we explore and identify the ways of endogenous development of decayed fabrics and their challenges ahead. The results of this research show that applying methods such as regeneration, improvement, renovation and reconstruction with respect to people's awareness and economic, social and cultural issues, etc., and the elaboration of issues can be used to develop the endogenous development of urban decayed fabrics and to prevent population elusion in decayed fabric.
