W12+ is a powerful partnership of motivated organizations, which act as catalysts and incubators of urban water solutions, by facilitating constructive conversations and dynamic dialogue within and between cities facing various water challenges. Focusing on the nexus of rapid urbanization and climate change, the W12+ approach looks at cities broadly in terms of their watersheds, bioregions, source water supply and potentially applicable innovations - bringing together humanity's top thought-leaders and technologies across multiple platforms and initiatives, to create and maintain sustainable urban water solutions for all.
