The GBH methodology is derived from a 1500 year old Native Hawaiian Ahupua’a approach. This approach defines sustainable relationships among land, water and humans from the tops of islands to the coral reefs and open ocean. GBH seeks a similar interconnection between the City of Boston and Boston Harbor: from watersheds to the harbor and its coastal habitats and islands.
