Executive Summary<br />
South Asia<br />
Most reefs in this region were severely affected and some were almost totally devastated<br />
during <strong>the</strong> extreme climate events <strong>of</strong> 1998. <strong>Reefs</strong> on <strong>the</strong> Maldives, Sri Lanka and parts <strong>of</strong><br />
western India lost much <strong>of</strong> <strong>the</strong>ir coral cover, whereas those on some parts <strong>of</strong> <strong>the</strong> east coast<br />
<strong>of</strong> Sri Lanka and most <strong>of</strong> <strong>the</strong> Andaman Islands were not seriously affected. These losses<br />
have added to major anthropogenic damage to reefs <strong>of</strong>f <strong>the</strong> mainland <strong>of</strong> India and Sri<br />
Lanka, particularly from coral mining, over-fishing and pollution. These pressures will<br />
continue as populations grow. There is an active regional network to assess coral reef health<br />
and socioeconomic aspects <strong>of</strong> coral reef use, which is raising awareness about <strong>the</strong> need to<br />
establish more protected areas.<br />
Eastern Africa<br />
All reefs in this region are close to <strong>the</strong> large continental land mass <strong>of</strong> Africa, and <strong>the</strong>refore<br />
experience all <strong>the</strong> impacts from land: significant levels <strong>of</strong> sediment run<strong>of</strong>f; nutrient<br />
pollution; and definite over-exploitation <strong>of</strong> reef resources from growing populations.<br />
Developing national programmes to assess and manage coral reefs for both sustainable<br />
fishing by local communities and <strong>the</strong> rapidly expanding tourism industry were given a<br />
major sense <strong>of</strong> urgency in 1998. There was massive coral bleaching and mortality associated<br />
with <strong>the</strong> El Niño climate switch with some large areas losing up to 80% <strong>of</strong> <strong>the</strong>ir live corals<br />
(especially parts <strong>of</strong> Kenya and Tanzania). There is now new coral recruitment, which is an<br />
encouraging sign for recovery, although it is probable that <strong>the</strong> reefs will have a different<br />
composition in <strong>the</strong> immediate term. A call has been made for improved regional<br />
cooperation to build national capacity and to manage transboundary problems.<br />
Sou<strong>the</strong>rn Indian Ocean<br />
The reefs <strong>of</strong> <strong>the</strong> nor<strong>the</strong>rn part <strong>of</strong> <strong>the</strong> region suffered severe damage during 1998 as a result<br />
<strong>of</strong> <strong>the</strong> El Niño bleaching, with losses <strong>of</strong> 80 to 90% <strong>of</strong> <strong>the</strong> corals in parts <strong>of</strong> <strong>the</strong> Comoros and<br />
Seychelles. <strong>Reefs</strong> around <strong>the</strong> sou<strong>the</strong>rn islands were only slightly affected, but <strong>the</strong> reefs <strong>of</strong><br />
Madagascar continue to be under very high human pressures. Prior to <strong>the</strong> recent formation<br />
<strong>of</strong> regional monitoring, <strong>the</strong>re was little capacity and limited baseline data. Now <strong>the</strong>re are 44<br />
permanent monitoring sites in <strong>the</strong>se states, however <strong>the</strong> capacity for <strong>the</strong> management <strong>of</strong><br />
coral reefs remains well behind many o<strong>the</strong>r parts <strong>of</strong> <strong>the</strong> world. A substantial Node <strong>of</strong> <strong>the</strong><br />
GCRMN was formed with European funding, and has received substantial support from <strong>the</strong><br />
Global Environment Facility to expand in <strong>the</strong> future.<br />
Sou<strong>the</strong>ast Asia<br />
This region has both <strong>the</strong> largest area <strong>of</strong> coral reefs in <strong>the</strong> world with <strong>the</strong> highest biodiversity,<br />
while <strong>the</strong> reefs are probably under <strong>the</strong> greatest threats from anthropogenic activities.<br />
Simultaneously <strong>the</strong>re is rapidly expanding capacity to monitor, research and manage <strong>the</strong><br />
coral reef resources, which must accelerate as both populations and <strong>the</strong> economies<br />
expand and put greater demand on reef resources. The extensive network <strong>of</strong> reef<br />
monitoring is documenting an inexorable decline in <strong>the</strong> status <strong>of</strong> <strong>the</strong> coral reefs, some <strong>of</strong><br />
which were also damaged by <strong>the</strong> 1998 bleaching event (but not as severely as those in <strong>the</strong><br />
Indian Ocean). The area is still <strong>the</strong> centre <strong>of</strong> <strong>the</strong> reef live fish trade, worth over US$1billion<br />
per year, with virtually all reefs being hit by roving cyanide and blast fishers. Comanagement<br />
with local communities is emerging as <strong>the</strong> best method to implement<br />
sustainable management <strong>of</strong> <strong>the</strong>se high diversity resources.<br />
