Resumen
The objective of this article is to analyze the implementation of eco-neighborhoods in the city of Madrid. This is a new formulation that joins, within neighborhood scale, purposes of environmental sustainability with social and economic aims. First, we make a general approach reviewing the initiatives proposed in the capital city and then we will make an analysis of the eco-neighborhood of Vallecas, the only one still working. We have looked through the official approach, the present bibliography, the official statements, the interpretations of the technicians, the resident?s opinions exposed in websites, social networks and press. The field research and the collection of information through conversations with the agents involved were the keys to verify the real results of the projects. We consider that the development and the conclusion of these initiatives have been a failure. The reasons are in its origin and the process of realization, but mainly in the confused premises that were the foundation of its design and localization. The absence of dialogue with neighbors and associations turned the official speeches and plans in something strange to the citizen?s necessities of the southern area, with the lowest rents of Madrid.
