Isla del Coco National Park is located
in the Eastern Tropical Pacific (5.5ºN,
87ºW), about 500 km offshore of the
nearest Costa Rican continental coast.
• Land area: 51,100
km2 (8.5% of the
total)
• Total (Sea+Land)
area: 598,700
km2
The island is part of the Eastern
Tropical Pacific Seascape
Project that includes the Galapagos
Islands and Marine Reserve
(Ecuador), Coiba National Park
(Panama) and the Colombian islands
of Malpelo and Gorgona.
Project: Knowledge and management of marine and coral reef environments of
Isla del Coco Marine Protected Area (P.I.: Dr. Jorge Cortés-4) . Funded by: the
French Fund for the World's Environment, the Vice-presidency for Research
and Marine Sciences and Limnology Research Center, Universidad de Costa
Rica.

GENERAL OBJECTIVE
- To generate information about the marine
ecosystems of Isla del Coco, in order to
improve its management and conservation
SOME SPECIFIC OBJECTIVES:
- Capacity building of the ACMIC personnel: Chemical and
Biological sampling. Physical and Biological data adquisition.
Early warning of atypical events and conditions. Data and
samples basic analysis.
- Generation of plans for future monitoring activities that could
help conservation and management.
Rainfall data
Why CC matters in this project?
Some expected CC Impacts (IPCC, AR-4, WG-II,
Chaps. 13-Latin America & 16-Small Islands):
•
•
•
•
•
•
•
The projected mean warming for Latin America to the end of the century,
according to different climate models, ranges from 1 to 4°C for the SRES
emissions scenario B2 and from 2 to 6°C for scenario A2 (medium confidence).
Under future climate change, there is a risk of significant species extinctions in
many areas of tropical Latin America (high confidence).
The expected increases in sea-level rise (SLR), weather and climatic variability
and extremes are very likely to affect coastal areas (high confidence).
Future sustainable development plans should include adaptation strategies to
enhance the integration of climate change into development policies (high
confidence).
Small islands, whether located in the tropics or higher latitudes, have
characteristics which make them especially vulnerable to the effects of climate
change, sea-level rise, and extreme events (very high confidence).
Climate change is likely to heavily impact coral reefs, fisheries and
othermarine-based resources (high confidence).
New studies confirm previous findings that the effects of climate change on
tourism are likely to be direct and indirect, and largely negative (high
confidence).
