Coral reefs are in danger globally. When it comes to Trinidad and Tobago, the projections by experts are worrisome.


Part of the problem is climate change which contributes significantly to what is known as coral bleaching.


While all is not lost, the experts say it could be if serious action isn't taken. The issue was addressed at a webinar "Coral Reefs Feel the Heat." Alicia Boucher has the details.

00:00 Coral reefs are beneficial for food, including fishing, tourism, recreation, coastal protection,
00:06 and medicine.
00:08 Algae live in the tissues of the coral host, and when those algae leave, the host corals
00:13 lose their beautiful colors and turn white.
00:16 This is known as coral bleaching.
00:18 Climate change, which factors in global warming, resulting in warmer oceans, is a major factor
00:24 of mass coral bleaching.
00:26 The Paris Agreement is intended on limiting global warming to 1.5 degrees Celsius.
00:32 Coral reef ecologist Dr. Angénie Ganaisse, who works at the Institute of Marine Affairs,
00:36 says if that occurs, there would be a further loss of 70 to 90 percent of coral reefs, and
00:42 if warming gets up to 2 degrees Celsius, this would result in the possible loss of 99 percent
00:49 of reefs.
00:50 With temperatures presently at 1.2 degrees Celsius globally, Dr. Ganaisse calls the situation
00:56 dire, and she provides the projections for Tobago.
00:59 It is likely that by 2040 to 2050, we're going to get annual severe bleaching effects.
01:07 So you're going to get severe bleaching on an annual basis on most of our sites, with
01:12 the exception of a few of our reef areas, which is the area in green, which are likely
01:17 to experience ASE in the decade after.
01:21 Prolonged bleaching eventually causes corals to become diseased or die.
01:26 According to Dr. Ganaisse, in 2010, it was recorded that 50 percent of coral cover in
01:32 Tobago was lost, and low-level bleaching has been consistently occurring in the past three
01:37 years.
01:38 The 2020 bleach trajectory is very similar to that of 2010, so we do expect a lot of
01:45 bleaching and a lot of coral mortality as a result.
01:49 In fact, our bleaching alerts started two months earlier than the previous years, where
01:56 we would get bleaching watch alerts in August.
01:58 This year, we got them in June.
02:00 A multi-pronged approach is being taken to address coral bleaching, including alerts,
02:05 monitoring, reporting, adaptative measures, and plans for recovery.
02:10 But among the things being labeled vital for this country are fisheries management and
02:15 pollution management.
02:17 So we've had the integrated coastal zoning policy passed only two months ago, and we
02:22 have a 10-year plan for implementation to improve that, but a lot needs to be done in
02:28 very little time.
02:29 You need cross-sector collaboration.
02:31 You need, you know, we need to work with WASTA, we need to work with the Water Sewage Authority,
02:36 we need to work with agriculture.
02:38 So there needs to be a lot of coastal zone and watershed management that needs to happen.
02:44 The IMA is also looking into other initiatives.
02:47 Biologist at the Perry Institute for Marine Science in the Bahamas, Dr. Valeria Pizarro,
02:53 is highlighting what she says is a key aspect to any initiative on prevention of coral degradation
02:59 and restoration.
03:01 You in every single solution, you have to involve community, yeah, social knowledge,
03:07 but you have to involve as well industry and especially tourism.
03:12 Like tourism, it's a key for our countries.
03:16 We actually depend and live from tourism.
03:19 So it's how we can reduce the, tourism has an impact.
03:25 I'm not going to be like, it's not, they're not like the best, but they can be very, they
03:31 can contribute so much if you know how to do it.
03:35 Apart from the availability of funding and investment propelled through the United Nations
03:40 focus on coral restoration, experts say more education is crucial moving forward and governments
03:46 in the Caribbean need to work together as the problems being experienced are similar.
