“…Despite the water crises scenarios in the RMSP over the last decade, there are only a few scientific research results related to the effectiveness of the water source areas statutes and its instruments (ALVIM; KATO; ROSIN, 2015;FERRARA, 2018;IKEMATSU, 2014). Still, recent water quality data indicate a scenario of degradation and worrying trends (FABHAT, 2019), suggesting the need to evaluate and improve current practices and instruments.…”

Strategic Environmental Assessment (SEA) is a tool that aims to integrate environmental issues into decision-making processes, usually to support the development of sectoral or territorial plans and programs. SEA is mandatory in the European Union and is applied to water management in France. Water management in Brazil is inspired by the French model, but does not have SEA; in the state of São Paulo watersheds of interest for public supply have specific norms and can count on a Development and Environmental Protection Plan (PDPA). In this research we explore three potential contributions of SEA as adopted in French water management for the case of the PDPA of the Billings Reservoir sub-basin. We conducted an evaluative case study for this PDPA, a literature review on French practices, and comparative analysis. We conclude by indicating potential contributions of SEA for the definition of objectives, scoping, and study of alternatives of the PDPA-Billings.

We estimated the economic value of ecosystem services provided by the legally protected vegetation in riparian zones (RPA- riparian protected areas) of watercourses of the Guarapiranga Reservoir watershed (São Paulo, Brazil), considering two scenarios: (i) the value of ecosystem services provided if the RPA recovery complies with the applicable environmental legislation; and (ii) the year 2030, maintaining the urbanization rate and the loss of vegetation cover in the watershed observed between 1986 and 2010. Accomplishing the first scenario demands reforesting 5,917.5 ha of the RPA, which may reduce the annual expenses with chemicals for water treatment and save USD 181.774 per 1000 m3 of treated water. For 2030, we estimated a loss of 6,220 ha of vegetation cover in the RPA (1986 as the initial reference). The loss of ecosystem services provided by RPA would result in an accumulated increase of about USD 318 million in water treatment costs between 2011 and 2030.
