Cambios en la valoración de la naturaleza en la Región Metropolitana de Barcelona

Abstract

Consequent to urban development, the perspective of nature value has evolved from protectionist concept to a vision of active, inclusive and multifunctional system. My on-going research reflects on this latest system that in the mid- 90s was coined as green infrastructure. The focus is on two issues: firstly trying to identify which is the new approach that provides green infrastructure concepts already developed and applied in the field of planning of open spaces. Secondly to analyse the relationship between this new concept and the green networks in regional planning of three metropolises: Barcelona, Bologna and London. In this paper I will present the case study of the metropolitan area of Barcelona, the process of evolution that drive the city to transform protected, but isolated natural elements on a complex system of open spaces, and finally its relationship with the green infrastructure concept.
