Desarrollo urbano sostenible

Environmental problems have become a worldwide concern for economists, as is witnessed by the development of many theories and policies aimed at driving the economy towards a ‘sustainable economy'. The problem becomes even greater if we discuss cities. The first scope of the paper is to offer an analytical framework for ‘urban sustainable development' to present the main economic concepts that are hidden under this label. In particular, different ‘environments' co-exist in a city: the natural, the artifact and the social environment.
