The Information Need
Few Coral Reefs Have Been Monitored
Inadequate Information on Changes in Coral
Reefs
Much Data Is Unavailable
Integrated Monitoring
Programs Are Needed

Goals of Reefs at Risk
Raise awareness about threats to coral reefs
Establish linkages between human activity
and coral condition
Develop a standardized indicator of threat to
coral reefs from human activities
Promote sharing and improvement of
information through data integration and
distribution
Main Components of Reefs at Risk
project:
Collection and integration of background
data sets on coral reefs and factors
contributing to reef degradation
Modeling of threats to coral reefs
Evaluate economic losses likely to result
from coral reef degradation
Threats Evaluated in Caribbean:
Coastal
Development
Watershed-based
sources of
sediment and pollution

Also Examined:

Threat: Coastal Development
Dredging, land
filling and
reclamation
Mining of sand and
coral
Runoff from
construction
Sewage discharge
Impacts from

Management effectiveness of
285 Caribbean MPAs
With the growth of tourism, fisheries, and other development in
coral reef areas, marine protected areas (MPAs) are an important
tool for safeguarding coral reefs.
6% of MPAs rated as good
13% of MPAs rated as partially
effective
48% of MPAs rated as inadequate
33% of MPAs under an
unknown level of management
Protection of the 26,000 sq km of
coral reefs in the region
Ineffective management of protected areas
further threatens Caribbean coral reefs.
80% of reefs outside of MPAs
1% of reefs in MPAs rated as
good
3% of reefs in MPAs rated as
partially effective
9% of reefs in MPAs rated as
ineffective
7% of reefs in MPAs under an
unknown level of management
Finding: If current trends in coral
reef degradation continue, coastal
communities and national
economies are poised to sustain
substantial economic losses.
Valuation: Coral reef-associated
fisheries
Net annual revenues of
over $300 million in
2000.
Fisheries could decline
by 30-45% by 2015
Estimated loss of net revenues between
US$95 million to US$140 million per year
by 2015.
Valuation: Dive Tourism
Net annual revenues of
over $2 billion in 2000.
Coral degradation could
results in a 2-5%
reduction in revenues
by 2015
Estimated loss of net revenues between
US$100 million to US$300 million per year
by 2015.
Valuation: Shoreline Protection
Over 20% of Caribbean
coastline protected by
coral reefs.
Estimated value of this
service is between $700
million and $2.2 billion.
Reef degradation could result in losses
estimated between US$140 million to
US$420 million per year by 2050.
