The Waipa Foundation is a non-profit organization which sponsors a program called ʻAina Ulu (in the Hawaiian language), funded by Kamehameha Schools.
Its programs grew out of community efforts to manage the ahupuaʻa of Waipa in the late 1980s. The Waipa Foundation was established as a 501(c)3 non-profit in 1993.
The foundation makes its home in the ahupuaʻa of Waipa, a valley on the north shore of the island of Kauaʻi in Hawaii, 22°12′4″N 159°31′0″W / 22.20111°N 159.51667°WCoordinates: 22°12′4″N 159°31′0″W / 22.20111°N 159.51667°W. The Waipa stream flows through the valley and empties into Hanalei Bay. An ahupuaʻa is an ancient Hawaiian land division from mountains to the sea, often corresponding to a watershed district. It was used in traditional Hawaiian times as a way to distribute the resources of the land to the people. The mission of the foundation is "the physical and cultural restoration of the ahupuaʻa of Waipa".
