Water and land management in the periurban catchment of Sao Paulo : a first conceptual framework
A common representation of the interaction between urban expansion and water quality degradation in the periurban context of São Paulo Metropolitan Region has been elaborated to integrate different thematic knowledge. The model combines (1) a representation of spatial dynamics, land uses and their evolution, based on a basic spatial unit of one ha, that allow to composing various spatial management unit of hydrological (e.g catchment area) or social interest (e.g. legal zoning). The plot is also viewed as the support for a unique land cover, land occupation and urban infrastructure, including water and sanitation ones (2) a typology of actors, based on land ownership and residence place. This classification differenciates actor with direct action on land and water (either by direct take off the resources, effluents production, infrastructure development and management, or land use changes) and other groups of interests which include most of the stakeholders groups represented in the catchment committee. (4) An hydrological representation allowing to articulating spatial processes, water allocation and simplified quality processes in potable reservoir. This model provides a generic interpretation frame for the specific situation of the periurban catchment of the RMSP. It is being used to develop tools to support capacity building and strengthen local actors' participation in the catchment committee.
