December 7, 2007 -- This week, international leaders took an important step toward protecting the world's coral reefs from the impacts of climate change, overfishing and coastal development.
Senior officials from six Pacific Island nations have come together to safeguard the marine and coastal habitats of the Coral Triangle, considered to be the planet's epicenter of marine biodiversity.
Covering nearly six million square kilometers, these rich seas are home to:
More than just stunning coral gardens, the Coral Triangle also provides resources for almost 126 million people who depend directly on the reef systems for food, jobs, tourism and coastal protection.
The total annual economic value of the reefs is $2.3 billion and this value is unparalleled. For example, it would cost an estimated $250,000 to $15 million per kilometer of coast to replace the Coral Triangle's reefs and mangrove forests with man-made coastal defenses.
Coral reefs, such as those in the Coral Triangle, are critical to the well-being of people and nature. Yet they are some of the most endangered ecosystems on Earth. Around the world, coral reefs are being degraded by:
But in the Coral Triangle, some reefs have demonstrated resilience to climate change—and that is cause for optimism.
So the Nature Conservancy is working with partners to establish and maintain marine protected areas to ensure the survival of these important natural systems. Resilient MPA networks in the Coral Triangle can serve as “global refuges” that can help replenish degraded reefs in the surrounding parts of Indonesia and neighboring countries.
Vigorous ocean currents in this area can help seed damaged reefs with healthy and resilient coral larvae and increase the chances of reef survival against the deadly impacts of climate change. Strengthening the resilience of natural systems — through efforts such as this — is also an important and cost-effective solution for people and societies beginning to plan for a future with climate change.
Nature-based adaptation strategies strengthen the ability of communities to deal with climate change impacts. For example, establishing networks of MPAs to protect coral reefs can help coastal communities survive through more intense storms and wave surges, while ensuring critical habitat for fish and other marine life.
Our Coral Triangle Center in Bali serves as a center of excellence for marine conservation as well as for the establishment of the MPA networks which, in Indonesia, include Komodo, Berau, Wakatobi, and Raja Ampat.
Governments convening this week in Bali under the United Nations Framework Convention on Climate Change will be addressing adaptation as a component of international agreements on climate change.
Also this week, senior government officials of the six nations represented in the Coral Triangle will hold the first formal planning meeting of the Coral Triangle Initiative — a new multilateral effort designed to help safeguard the region’s marine and coastal biological resources for the sustainable growth and prosperity of current and future generations.
Addressing the climate change linkages to the marine resources of the Coral Triangle is likely to become a major element of the Coral Triangle Initiative. The outcomes of this meeting could lay the foundation for protecting the Coral Triangle — and reduce the impacts of climate change on many of us who live within its boundaries.
Such action in the Coral Triangle would be an important start, and could demonstrate that international efforts for adaptation must focus on more than just building infrastructure to address climate change.
Infrastructure changes — such as seawalls or dykes that buffer storms — can be necessary in some instances, but can also:
