on coral reef research and management
October 2002, Townsville Queensland Australia
- Overfishing and pollution have driven massive and accelerating
decreases in abundance of coral reef species and have caused global
changes in reef ecosystems over the last two centuries. If these
trends continue, coral reefs will decline further, resulting in the
loss of biodiversity and economic value (8, 9, 14).
- Outbreaks of coral bleaching have greatly increased in frequency and
magnitude over the past 30 years, and are tightly linked to increases
in temperature. A similar increase has occurred in coral disease (7,
- Projected increases in carbon dioxide and temperature over the next
50 years exceed the conditions under which coral reefs have flourished
over the past half million years (10, 11, 14, 16).
- The accelerating rate of environmental change diminishes the
evolutionary capacity of many coral species to adapt (6, 8).
- Global warming is not an all-or-none scenario for coral reefs. Reefs
will change rather than disappear entirely. The challenge is to work
out how, why, and what the consequences will be in relation to the
other problems faced by coral reefs (1, 3, 6, 7, 8, 16).
- Current management strategies need to be vigorously implemented and
complemented by strong policy decisions to reduce the rate of global
warming. International and national integration of reef management
strategies is an urgent priority (2, 5, 13).
- Marine protected areas are currently the best management tool for
preserving coral reefs, especially for extractive activities such as
fishing. To be effective, 30 - 50% of the available reef area should
be no-take (no fishing) for long-term protection of coral reefs and
their services (2, 3, 9, 17).
- No-take reserves are a powerful tool, but they can only work if
combined with effective management of surrounding areas. This requires
a strong focus on supporting reef resilience, which involves reducing
pollution, protecting food webs and managing key functional groups
(such as herbivores) as insurance for sustainability (1, 2, 3, 5, 6,
9, 12, 13).
- Coral reefs are the global canaries, as they are already showing
rapid responses to climate change at the global scale. Scientists,
managers and policy makers can use reefs to examine the effectiveness
of international attempts to understand and respond to the impact of
global warming (1, 7, 11).
- The maintenance of reef structures requires that rates of reef
growth balance rates of erosion. Future changes in ocean chemistry due
to higher carbon dioxide may cause dissolution or weakening of the
limestone that makes reefs (1, 3, 10, 14,16).
- Coral reefs support social and economic development and therefore
need to be sustained. To achieve this goal there is a clear need to
reduce the rate of global warming (5, 17).
