Urban tax related to indicators of water quality and quantity upon long-term policy scenarios: A case study of urban conditions at Southeast Brazil

Abstract

To adopt new tools of urban development strategies, combined indicators of water quality and quantity were here outlined. This paper aimed to propose a new method of assessment of urban tax (UT$) related to a diversity of water indicators based upon long-term policy scenarios. Thus, in order to promote the monetary values of environmental services, indicators of blue and grey water footprints (WF) of urban drainage, solid waste and domestic sewage were integrated with other indicators at urban lot scale. Besides, a series of equations of UT$ based on organic loads (OL), maximum soil water storage (Smax) and maximum flow (Qmax) were studied and related to WF in the value of urban lot taxes. Four Millennium Ecosystem Scenarios were projected to urban lot systems, through different trends of WF, OL, Smax and Qmax, from current conditions until future planning horizons of UT$ in the period of years 2025 to 2100.Proactive policy scenarios incorporated adapting structural measures in order to minimize the impacts of increasing impervious areas at long-term. Finally, sensibility analysis of UT$ was discussed from a case study of urban conditions at Southeast Brazil.
