This chapter investigates the relation between green infrastructures and urban territories in contexts in which landscape had suffered recent and sudden changes. Taking the example of Portugal, the methodology applied uses the European Landscape Convention’s concepts to discuss how landscapes can be perceived and how spatial planning tools can integrate these new concepts. In order to discuss this, information about the recent revision of a land-use plan in the western coast of Portugal, the municipality of Óbidos is provided. The chapter suggests that new opportunities, but also new challenges, exist in terms of integrating new landscape concepts and new spatial planning paradigms. This implies also the search of new meanings for green infrastructure.
