Elaboration and analysis of social indicators as an instrument to support decision making in the process of depollution of the Guanabara Bay

Abstract

Despite the efforts in the depollution since the 1990s, evolution of the damaged social scenario in the region of the watershed of the Guanabara Bay is not perceived by the public opinion. The importance of social indicators emerges in a moment in which rendering account to the population regarding investiments and results obtained, orienting actions for emergency social and local issues and monitoring results for identification of adjustments to the actions for the achievement of better results is necessary. The current agenda for debating social issues of the region of the bay represented the basis for the creation of a system of social indicators. Three watersheds in depollution process were also studied, focusing on their approaches regarding social issues. A theoretical model of indicators was developed and tested in a draft of the Guanabara Bay watershed, using the public data available. The model proved to be a useful tool for an holistic approach of the bay by providing information on the better orientation of depollution actions for more effective results in both social and environmental issues.
