Thanks Eugene for highlighting the report in the Australian newspaper and to the other comments about the article with sources.
From my perspective, mitigation against climate change is as much about scientists pointing out perceived reporting bias, and correcting errors of fact, as it is about say, studying trends in coral growth, or building resilience of coral reefs.
Investors considering a large scale infrastructure development in the Maldives (or elsewhere) should be aware it is not only sea level rise that may cause the Maldives to go under, or rather the RATE of sea level rise, but other factors requiring mitigation against climate change. Protecting the reefs should be a priority in their management decision making in a delicate reef ecosystem, but is not always the case.
Dredging. ........sedimentation, nutrients, disease.
Since 2007, there have been 34 new resort developments (currently a total 106 resorts, 15 hotels), 107 guest houses, and many major resort upgrades, as well as harbor, airport, and other island infrastructure developments around the Maldives. (Atlas of the Maldives, 2007, Atoll Editions, and http://planning.gov.mv/en/content/view/318/93/ , although the latest map needs updating) with many more planned. Dredging plays a major role in many of these developments and conversations with the operators and personal observation tells me little, if any attention, is being given to minimizing the impacts to protect reefs and sensitive lagoon nursery areas. Nor am I aware of any effective monitoring being done.
There is now considerable extra pressure on reef fin fisheries brought about in part, by the existing live reef fish export trade, combined with a shift in fishing effort from the previous shark fishery to the reef fin fisheries, an increase in consumption of the combined Maldivian and Foreigner population,
and an in increase in the number of tourist arrivals. The demographics are changing too, (40% Chinese February, 2015).
There have been some positive developments though, (total shark ban 2010 and rays 2013, 5 grouper special protected areas 2014), on top of the already existing 27 MPA’s.
Although there have been COTS outbreaks in the past, a current outbreak – centred around the central north west, west, and south west of North Male’ Atoll – has gained momentum over the past 6 months. There have also been reports of increasing COTS numbers in South Male Atoll and also in the far north at Haa Alifu Atoll, and possibly elsewhere. Some reefs and resort housereefs have been devastated.
I point out these facts because collectively, based on my reading and common sense, they will make our reefs more vulnerable if we have another major bleaching event. Uninformed or incorrect comments about sea level rise and mitigation with reference to the Maldives made by the head of major news corporation who sets standards and policies for their companies newspapers will inevitably, rightly or wrongly, lead to allegations of bias against their paper’s writers. Hence the dirty water…..
