What is Resilience Measures

This chapter aims to discuss concepts and methods to measure the landscape resilience of urban systems and test the indicators framework in the Portuguese regional context. The objective is to measure the performance and the direction of the urban changes in different phenomena, as well as to evaluate the level of urban systems preparation for a desired and undesired change adaptability. The approach to these issues is analyzed in the literature, dividing the aforementioned analysis into the resilience of the economic base, of the social structure, and of the urban form. In brief, the chapter meets three objectives: firstly, defining the framework of principles more commonly associated with urban resilience; secondly, providing a selection of indicators that embodies the different proposals of measurement; and thirdly, applying the indicator matrix to two Portuguese case studies (Caldas da Rainha and Évora urban systems).
