Land and People

In Season 5 of Land and People, hosted by Melissa Chimera and Clay Trauernicht, and produced by Kaheāwai Media, we turn our attention to Oʻahu and the water issues that have been top of mind for so many after 2026’s extreme weather, beginning with the Kona lows. Along the way, we’ll also hear from experts across Hawaiʻi whose knowledge spans everything from rapid response after climate events to long-term stewardship of wai, ʻāina, and communities.In our Season 5 premiere, we’re joined by Barry Usagawa, Water Resources Program Administrator at the Honolulu Board of Water Supply.Barry traces his connection to land and water back to his upbringing in Hilo, his father’s work as a forester, and more than four decades in public service. The conversation explores watershed stewardship, extreme rainfall and flood response, climate adaptation, and the value of community-led, mauka-to-makai management of water systems on Oʻahu.Key takeaways:Healthy forests are essential infrastructure for reliable water.Extreme rainfall calls for long-term, integrated preparation — not just emergency response.Cultural knowledge and community leadership are central to sustainable resource management.Traditional practices based on Hawaiian ahupuaʻa management now guide the Board of Water Supply’s own approachChapters:00:00 ~ Welcome to Season Five04:12 ~ Meet Barry Usagawa11:37 ~ A Career in Water Service20:57 ~ Land Use, Water, and Watersheds29:29 ~ From Water Supply to Watershed Stewardship34:29 ~ Responding to Flooding and Emergencies45:22 ~ Climate Adaptation Through One Water57:14 ~ Community-Led Water PlanningTopics:Watershed protection; public water systems; the Waiāhole Ditch case; flood preparedness; reservoirs and emergency response; climate adaptation; recycled water; seawater desalination; stream restoration; ahupuaʻa-based planning; community stewardship.Credits:Guest: Barry UsagawaHosts: Melissa Chimera & Clay TrauernichtProducers: Kaheāwai Media (Tyler Sonnemaker & Landon Tom)

Sierra McDaniel is the resources management program manager at Hawaiʻi Volcanoes National Park, having worked at the park for 25 years. She first came to Hawaiʻi as a biology undergraduate and then entered the University of Hawaiʻi at Hiloʻs Tropical Conservation Biology and Environmental Science masters program. She speaks to the challenges of working to conserve ecosystems, endangered species, and cultural values across the 354,461 acres, a place that hosts over 1.5 million visitors annually. We get into the challenges of changing ecosystems in response to fire on the landscape, the value of grounding the biological conservation work in Hawaiian lifeways and what it means to be in a place where volcanic eruptions are a constant presence.

In this episode, Melissa and Clay talk to Waikōloa Dry Forest Initiative executive director Jen Lawson and preserve manager Rob Yagi about their work to promote and restore one of the most endangered ecosystems in the world. Formed in 2011 to protect, promote, and restore a native Hawaiian dry forest after years of grassroots advocacy, the Waikōloa Dry Forest Preserve was established to protect many of the remaining native trees in the region. We get into Jen and Robʻs respective backgrounds in biology, how they came to Hawaiʻi through their stewardship of Pōhakuloa Training Area, and the unexpected rewards and challenges in helping to enhance the wiliwili forest that is so public facing, in the midst of fires, browsing goats and weeds.

Dr. Jim Jacobi has spent the past 50 years in Hawaiʻi as a biologist specializing in mapping Hawai’i’s unique ecosystems and studying the plants and animals contained within them. Like so many of his cohort, he is a skilled naturalist, having worked on introduced rats, native insects first for the Bishop Museum and then mapping vegetation and management research projects for the Pacific Island Ecosystems Research Center of the US Geological Survey in Volcano. We talk to Jim about the evolution of tracking changes in vegetation by hand from aerial photos to the use of computer mapping and modelling. He shares with us the unique experiences heʻs had across the rugged U.S. Fish and Wildlife Service transects that traverse mountainous summits to sea, as well as the profound sorrow in witnessing the last Hawaiian honeycreeper in the wild, the Kauaʻi oʻo.

David Okita has flown helicopters on Hawaiʻi Island for many decades, first for emergency responders assisting with fire department search and rescues and then later for conservation organizations like The Nature Conservancy and the Department of Land and Natural Resources. David reflects on how flying for him has been a family affair, growing up on Hawaiʻi Island beginning with his dad in the 1970s, and now with his son as his assistant. He speaks to the unique relationship between helicopter pilots and the forestry and biology field crews he supports–one of mutual respect and admiration for the skills and hard work required to build fences, monitor ecosystems and conserve endangered species in the remote wilderness.
