Native Hawaiian land stewardship groups say reviving the traditional ahupuaa system could help Hawaii handle the severe storms hitting the islands, which is good news for flood-prone communities but requires undoing decades of poor land planning.

• Co-founders of Papahana Kuaola and Hui Ku Maoli Ola are restoring the ahupuaa system, the traditional practice of managing land as one connected system running from the mountains down to the sea.
• The system worked well historically because every person living within an ahupuaa had a personal responsibility to care for it, unlike today when only a small number of organizations handle that stewardship.
• Restoring native stream systems, widening channels and clearing out invasive plants like mangrove and guinea grass, lets floodwater spread out safely instead of backing up into neighborhoods.
• Recent extreme storms, including Kona lows, showed the risk of building homes and farms directly in natural floodplains, and the group wants to "renaturalize" that land rather than just engineer around the problem.
• The groups have worked together for over two decades across Waimanalo, He'eia, and Kaneohe, building personal relationships that keep restoration efforts coordinated and accountable.

Outlook: Expect continued pushback toward restoring native watershed systems as a long-term defense against worsening storms, though the organizers say it will take sustained commitment from communities, businesses, and landowners.
