Cities are continually shifting. Sometimes change will affect growth, whereas at other times it will lead to decay. Development and decline are reflected in the built environment through the dynamics of evolution (including renovation and renewal) and decay, the difficulty of this project turns out from the increasing complexity of urban environments and from the unpredictability of external changes, two styles that have promoted environmental awareness and, consequently, contributed to a

... g debate on the relationship between city and nature. By looking at urban resilience through the lens of urban variety. It can be touched on to urban form as a product of the continuous tension between recovery and adaptation on several spatial and temporal scales of transformation. Although recent resilience approaches, such as spatial resilience, general resilience, and urban resilience, have dealt with urban form indirectly, and, conversely, some works in urban morphology have tried to comprehend the complexity of urban-natural environments, an explicit morphological perspective on urban resilience is still lacking in research. The paper is divided in three main parts: formal thinking of resilience, resilience of urban form (fitness, performance, and sustainability), and an urban network perspective on the two concepts. It closes with a discourse on the possibility of a space morphological approach to general urban resilience.
