Theoretical Contribution towards an Environmental Marker Systemized By a Pressure, State, and Response Model in the Management of Urban Rivers
Arminda Saconi Messias, Carlos Mello Garcias

The way which hydric resources are managed has been degrading water sources to a point it jeopardizes the quality of life of the populations, presenting an impending risk of water shortage even where water abounds. In the present work a proposal of methodological models to guide the assessment and monitoring of revitalization programs of urban rivers through sustainability markers linked to the pressure, state, response (PSR) method is presented. The methodological procedures included literature review and selection/proposal of selected parameters. After thorough analysis of the relevant factors over urban rivers concerning effective environmental management an environmental dimension with three subjects (indicators) fully characterized in name, definition, importance, measurement mechanism, unity of measurement, frequency of data collection and adjustment to the PSR model. The aforementioned models allow the assessment and monitoring of public programs and policies that aim to endorse practical actions towards environmental sustainability in the surface hydric clean urban resources.
