Brazil’s 1997 National Water Resources Policy stipulates multiple uses for water and establishes the need to guarantee its availability for present and future generations. However, in practice, a disproportionate share of available water resources goes to productive or extractive sectors over municipal users. FASE seeks to reinvigorate provisions in the national policy to improve the sustainable, democratic administration of water resources. It will emphasize three methodological components to enhance equity and access to water and build a culture of valuing and safeguarding water resources: 1) conducting participatory mapping of water resources to pinpoint vulnerabilities and explore ways to improve water security, 2) developing low-cost, low-technology tools and approaches to enhance water accessibility in poor urban areas, and 3) identifying strategies to bolster the safeguarding, decontamination, and regeneration of water sources. FASE sees an opportunity for these innovations, once demonstrated, to be adopted into the National Water Resources Management System (established by the 1997 policy) that could potentially affect millions of lives.
