The first Purple Prize competition provided the opportunity to socialize a different framework for thinking about technology and innovation development. The top three teams in the 2016 competition developed projects and prototypes that successfully employed modern technology, grounded in Hawaiian values and designed with Hawaiian sensibilities. Now is the time to be bold and promote indigeneity as a platform to foster technology innovation that is rooted in island and Hawaiian values that serve the land, people, and communities. The Purple Prize 2017 Waiwai Challenge provides this opportunity. As a theme for the competition, waiwai would address problems relevant to freshwater conservation, protection, and management in Hawaiʻi. We view potential synergies with our local efforts focused on wai, such as the Hawaiʻi Fresh Water Initiative and the work at the University of Hawaiʻi’s ʻIke Wai Project as well as national efforts like IDEO’s Water Resilience Challenge and Climate Ventures 2.0, a global accelerator focused on Agriculture and Water Systems Resilience.
