Fundamentos para o gerenciamento integrado dos recursos hídricos na microbacia urbana do rio Maguari-Açu com vistas à sustentabilidade hidroambiental

Abstract

The city of Ananindeua, as part of the Belém Metropolitan Region - BMR, has received the negative impacts resulting from the disorderly occupation of territorial space. The natural conditions of the region have been ignored in this process of urban settlement, which is verified by analyzing the current status of surface and underground water resources, which are being rapidly degraded, because of the lack of interventions, that are primarily that guarantee government control of these impacts or the implementation of actions merely reproduce historical actions without success. The analysis of socioeconomic and hydro-environmental conditions demonstrated the hydro unsustainability of this region, as well as the existence of the various conflicts that refers specifically to water resources. In order to counter this situation, are presented basis for the integrated management of water resources in the urban watershed of the river "Maguari-Acu," which seek to reach this sustainability. Such basis were structured in five (05) actions: 1) Division of BMR in six (6) river basin, 2) Environmental zoning in River Basin of Maguari-Açu, 3) Management of soil sealing and runoff, 4) Strategies of social organization for the management of urban watersheds and 5) management of information from the integrated data base. To support such basis, future scenarios were developed, anchored in the legal framework and the existing technological apparatus, instruments sufficient for integrated actions between the government and society in general, making it possible to undertake the processing needed for the construction or reconstruction of cities from principles of sustainability.
