TNC globally works at more than 40 demonstration sites worldwide to use nature-based defenses to reduce communities’ risks to storms and protect and restore important coastal areas, engaging the insurance/reinsurance sectors and global banks and lenders to make natural infrastructure part of any coastal development insurance and lending decisions and partnering with engineering firms to include nature in new development designs.
Hawaii, American Samoa, Guam, CNMI, and minor outlying islands
Ofu Lagoon, part of the National Park of American Samoa, contains a healthy coral reef habitat that supports a diversity of species. The park is working with university partners towards the goal of understanding the unique adaptations of the coral in Ofu Lagoon to multiple environmental stressors associated with climate change.
When we leave the house in the morning, we often check the local weather forecast and make some quick decisions: Should I bring an umbrella? How about a sweater? By assessing the risks and taking action, we are effectively mitigating our vulnerability to weather-related impacts. While most people do not think twice about weighing uncertain weather information and taking action based on their best estimate of risk, it has proved much more difficult for community members, policymakers, and natural-resource managers to integrate climate forecasts into their decision-making processes.
This report sets out the full extent of the threats and proposes solutions to the challenges facing the Coral Triangle and its people. Based on a thorough consideration of the climate, biology, economics and social characteristics of the region, it shows why these challenges are increasing, and how unchecked climate change will ultimately undermine and destroy ecosystems and livelihoods in the Coral Triangle.
Developing an adaptation strategy for a region as enormous and variable as the Pacific is no small task. The ecological, political, climatic and socioeconomic realities throughout the region contain all of the extremes that can be found on the planet. Countries around the Pacific have tended to form coalitions along sociocultural lines—Pacific Island nations, Latin America, or the Arctic, for instance. Yet all are bound together by the Pacific Ocean, whose climate systems, currents, and species cross the boundaries of these traditional human groupings.
Planning community resilience to sea level rise (SLR) requires information about where, when, and how SLR hazards will impact the coastal zone. We augment passive flood mapping (the so-called “bathtub” approach) by simulating physical processes posing recurrent threats to coastal infrastructure, communities, and ecosystems in Hawai‘i (including tidally-forced direct marine and groundwater flooding, seasonal wave inundation, and chronic coastal erosion).
The Hawaiʻi Sea Level Rise Viewer (Viewer) is intended to provide an online atlas to support the Hawaiʻi Sea Level Rise Vulnerability and Adaptation Report (Report) that was mandated by Act 83, Session Laws of Hawaiʻi (SLH) 2014 and Act 32, SLH 2017.
Sea level rise is an inevitable outcome of global warming that will continue through many centuries even if human-generated global greenhouse gas (GHG) emissions were stopped today. However, much of what happens with future sea level rise will depend on our ability, or inability, to implement aggressive global carbon emissions reduction programs envisioned through the 2016 Paris Climate Accord.
The Community-based Mangrove Rehabilitation Project of the Zoological Society of London ran from 2008 to 2012 with the aim of increasing coastal protection, food resources and livelihood income of coastal communities in Panayand Guimaras by rehabilitating abandoned government-leased fishponds to mangroves, re-establishing legally mandated coastal greenbelts, and securing tenure on coastal land through Community-based Forest Management Agreements (CBFMAs).
