Regional Vulnerability Assessment in the Hawaiian Archipelago

  • Principal Investigator(s): Chris Sabine
  • Fiscal Year Funded: 2010

Chris Sabine – University of Hawai’i at Manoa

Assessing Current and Future Ocean Acidification and Climate Vulnerabilities Along the Hawaiian Archipelago

Why we care
The Insular Pacific-Hawaiian Large Marine Ecosystem (IPH-LME) Complex provides critical benthic and oceanographic habitats for important fisheries and protected resources. A critical missing piece in assessing vulnerability in the Hawaiian Islands to ocean change is understanding the variability of ocean properties and ocean acidification in space and time. Coral reef managers are particularly challenged with sustaining the ecosystem functions and services under changing environmental and human impacts.

What we are doing
This project takes a modeling approach to link the state of the ecosystem with societal outcomes to assess risk vulnerability in the IPH-LME. Researchers will combine state-of-the-art climate, regional, and coral reef ecosystem models with satellite assessments of ocean acidification. Results will provide robust projections of ocean acidification-related stress across the IPH-LME for the next 5 decades (2020-2070. Societal data will be collected through interviews, workshops, and community surveys to expand the number of relationships modeled. Vulnerability of the Hawaiian Islands to the projected ocean acidification-related stress will be evaluated using relationships between ecological and social state components. Resource managers will evaluate tradeoffs between different management practices and climate futures to determine which interventions would be most effective in supporting ecosystem integrity while enhancing societal wellbeing in the face of ocean acidification.

Benefits of our work
Collaboration between scientists, managers, non-governmental organizations, and resource users will help ensure that socio-economic and biophysical processes are both considered when evaluating consequences of policy decisions and climate projections. This transdisciplinary approach provides opportunities to build relationships among the project stakeholders. This project directly supports the Hawai‘i Division of Aquatic Resources (DAR) in its efforts to develop vulnerability analyses and a state action plan for ocean acidification to build adaptation and resilience in communities affected by ocean acidification. The social vulnerability analysis method developed under this project will have broad applicability for U.S. regions of the Pacific Ocean.

ADAPTING TO OCEAN ACIDIFICATION

The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.

Adaptation approaches fostered by the OAP include:

FORECASTING

Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare

MANAGEMENT

Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes

TECHNOLOGY DEVELOPMENT

Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally

REDUCING OUR CARBON FOOTPRINT

50 more ways to reduce your carbon footprint >

On the Road

Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.

With your Food Choices

Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill

With your Food Choices

Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources

By Reducing Coastal Acidification

Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats

TAKE ACTION WITH YOUR COMMUNITY

You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?

Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live.  As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action.  As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification.  Here are some ideas to get started:

  1. Work with informal educators, such as aquarium outreach programs and local non-profits, to teach the public about ocean acidification. Visit our Education & Outreach page to find the newest tools!
  2. Participate in habitat restoration efforts to restore habitats that help mitigate the effects of coastal acidification
  3. Facilitate conversations with local businesses that might be affected by ocean acidification, building a plan for the future.
  4. Partner with local community efforts to mitigate the driver behind ocean acidification  – excess CO2 – such as community supported agriculture, bike & car shares and other public transportation options.
  5. Contact your regional Coastal Acidification Network (CAN) to learn how OA is affecting your region and more ideas about how you can get involved in your community
