Presentation Overview Background on Reefs at (R@R) project series Partnership for R@R Caribbean Project concept and method Key findings of analysis Future events and products
4
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
5
Global Analysis released in 1998 by World Resources Institute, in collaboration with ICLARM, WCMC and UNEP

11
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
12
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
13
Threats Evaluated in Caribbean: Coastal Development Watershed-based sources of sediment and pollution Marine-based threat Overfishing
14
Also Examined: Coral Bleaching Coral Disease
15
Threat Analysis Method Inferential modeling
16
Dredging, land filling and reclamation Mining of sand and coral Runoff from construction Sewage discharge Impacts from tourism Threat: Coastal Development Replace photo
17
Finding: COASTAL DEVOPMENT threatens an estimated one-third of Caribbean coral reefs. Low Medium High Estimated threat
18
Threat: Sediment and Pollution from Inland Sources Land clearing Poor agricultural practices Fertilizer and pesticide runoff
19
Watersheds are critical units for analysis and management Puerto Rico Elevation

22
Watershed-based analysis
23
Finding: SEDIMENT AND POLLUTION FROM INLAND SOURCES threaten more than one-third of Caribbean coral reefs. Low Medium High Estimated threat
24
Threat: Marine-based Pollution and Damage Discharge of ballast water Oil spills and leaks Anchor damage and groundings
25
Finding: MARINE-BASED THREATS to coral reefs are widespread across the Caribbean. Low Medium High Estimated threat
26
Threat: Overfishing Widespread fishing exceeding sustainable levels Alters ecological balance on coral reef Overharvest of many commercially valuable species
27
Finding: OVERFISHING threatens over 60 percent of Caribbean coral reefs. Low Medium High Estimated threat
28
Regional Summary LowMediumHighVery High
29
Finding: INTEGRATED THREAT - nearly two-thirds of Caribbean coral reefs are threatened by human activities. Low Medium High Very High Estimated threat
30
How much reef are we talking about here?
32
Finding: Degree of human pressure on coral reefs varies considerably across the region. LowMediumHighVery High
33
Sub-Regional Summary – Continental SW Caribbean LowMediumHighVery High Reefs at Risk in the Continental Southwestern Caribbean
34
LowMediumHighVery High Reefs at Risk in Puerto Rico Country Summary – Puerto Rico
35
Finding: Finding: Diseases and rising sea temperatures threaten to damage coral reefs across the Caribbean region.
37
Management effectiveness of 285 Caribbean MPAs 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 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.
38
Protection of the 26,000 sq km of coral reefs in the region 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 Ineffective management of protected areas further threatens Caribbean coral reefs.
39
Finding: If current trends in coral reef degradation continue, coastal communities and national economies are poised to sustain substantial economic losses.
40
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.
41
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.
42
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.
