Associated territorial management, the way to transform the periurban area into a green belt

La Plata, like all cities, based its territorial organization -and landscape- on the construction of an inhabited area surrounded by productive green rings. Subsequently, like all other urbanizations, growth by extension generated a fragmented and degraded periphery. Currently, the periurban area presents a growing demand, dispute and conflict between different social groups that is beginning to be included in the political and management agenda. The purpose of this paper is to contribute to the construction of a new management model to transform the periurban area into a green belt, as an environmental, economic and social asset for the whole society.
