The State of Asia Pacific Coral and Marine Ecosystems and their Economic Value
Eleanor CarterSecond Asian Judges Symposium on Environment,
Manila, December 2013
Critical Marine Ecosystems in Asia Pacific
Coral Reefs Seagrass Mangroves
Engines of the Ocean
• Nursery for > 25% of all marine life globally• Cover < 1% of ocean• Asia Pacific has highest diversity and productivity
Southeast Asia
Highest population dependency on reef systemsCoral Triangle ~ 1/3 of worlds coral reefs
Essential Natural Capital
• Fisheries & Food Security• Tourism & Recreation • Resilience against Climate Change• Defense system for Coastal Development• Medicines
Fisheries & Food Security• Southeast Asia coral reef fisheries = US$2.4 billion / year (WRI, 2002)
• Coastal fisheries resources in the Coral Triangle (2010) - (ADB, 2013)- supported livelihoods & food security for > 373 million people - contributed 11.3% (19.1 tns) of all global capture fisheries and aquaculture production. - provides 1.2% to 6.8% of GDP in CT6 nations
• Av. 36% of protein needs (up to 80% in remote / rural locations) (CRA,2013)
• Indonesia - 95% harvest from artisanal fishers (FAO, 2013)
Tourism & Recreation
• High value habitats for tourism
• Reef associated tourism - up to 30% of national export earnings AP
(World Bank, 2010)
• $18 billion USD / yr generated in the Coral Triangle
Resilience against Climate Change
• Blue Carbon – 60% of global potential in Asia and Oceania Est. $10-$20/ton value under EU Emissions Trading Scheme (Siikamaki et al.,
2012)
• Defenses against storm-surges
Defense system for Coastal Development
Coral reefs mitigate 75-95 % of wave energy (Brander et al., 2004)
Example: Loss of 11 & 2% (respectively) of the Gulf of Thailand and Andaman Sea coastlines is equivalent to loss of US$156 million real estate value
(World Bank 2006).
Medicines• Prospects of new
medicines 300-400 times greater than terrestrial ecosystems (Bruckner, 2006)
• Japan investing up to $1 billion research each year
Treatments currently available for: CANCER, ARTHRITUS, ASTHMA,
ULCERS, BACTERIAL INFECTIONS, HEART DISEASE, VIRUSES, etc etc
Overall Economic Value of Resources
Example: Malacca Straits coral reefs = ‘combined’ economic value of US$ 563 million (WRI, 2011)

Rapidly declining habitats & resources
75% reefs globally under threat (WRI, 2011)
20% world mangroves destroyed“.. stocks of all species currently fished for food are predicted to collapse by 2048.” (Worm et al, 2006)
Asia Pacific
• Threats “..most severe in Southeast Asia”
• 95% reefs threatened
• 50% classified as ‘high’ or ‘very high’ threat status
(WRI,2011)
Causes of decline
• Habitat removal / destruction
• Pollution• Sedimentation• Overfishing• Destructive Fishing• Climate change
Top Threats
Est. net economic loss from blast fishing in Indonesia ~ US$570 million over the next 20 years
(WRI,2011)
Overfishing & Destructive Fishing
Challenges of fisheries management & enforcement
• Licensing• Regulating &
enforcing sustainable catch quota’s
• Enforcing protected areas (refuge’s for breeding stock)
Habitat removal / destructionEx: Loss of original mangrove cover by early 1990’s
•Malaysia ~ 75% •Thailand ~ 84 %•Vietnam ~ 37 %•Myanmar ~ 75% •Philippines ~ 67 %•Brunei ~ 20 %•Indonesia ~ 55%(Burke, 2001)
SummaryCoral and marine ecosystems
• Critical habitats for livelihoods, health and economy of nations• Under considerable threat – declining rapidly• Appropriate Legal & Judicial frameworks critical to sustain
natural capital• Urgent need to close the gap between policy, legislation,
implementation & enforcement
