PVS
The Polynesian Voyaging Society (PVS) is a non-profit research and educational corporation based in Honolulu, Hawaiʻi. PVS was established to research and perpetuate traditional Polynesian voyaging methods. Using replicas of traditional double-hulled canoes, PVS undertakes voyages throughout Polynesia navigating without modern instruments.

Fishponds
The Hawaiian people practiced aquaculture through development of fish ponds or loko iʻa. These fishponds were typically shallow areas of a reef flat surrounded by a low lava rock wall (loko kuapā) built out from the shore. Today community members work to restore many of the historical fishponds
Loʻi
There once was a time when most of Waikiki was covered in loʻi. Hawaiians grew and harvested their main staple kalo or taro in these loʻi. The garden consisted of an intricate irrigation system that took advantage of the many streams, using gravity to carry water throughout the loʻi to feed the kalo. While most of the Loʻi, especially on Oʻahu, are no longer in use, many Loʻi have been restored and are used for cultivation and educational outreach.
Architecture
Hawaiians are expert architects and engineers. Their built structures provided shelter from all the elements. Hawaiian continue the practice today.
