Raja Ampat Coral Bleaching 2024: Caught in the Confluence - Video by Dr. Phil Dustan

[bghazzal]

Hello all,
This video by Dr. Phil Dustan was posted on the Bird's Head Seascape network, and I thought some might be interested.

Continuing coverage of the Raja Ampat Coral Bleaching Event: "Caught in the Confluence of Global Warming and Ecotourism".
 

In October 2024, a marine heatwave struck the iconic coral reefs of Raja Ampat.
Corals in the Dampier Straits experienced severe bleaching and mortality, fueled by increasing levels of sewage from rapidly expanding ecotourism. Unless the sewage threat is eliminated, the World’s richest reefs and the economy they support will collapse.

It's good to see sewage/waste water finally mentioned so clearly. Development-related run-off, silting and pollution have been an issue on house-reefs for a while in certain areas.

On a personal note, I remember seeing the change betwen 2014 and 2017 (which was my last visit to Central RajaAmpat / Dampier Strait), with house-reefs being seriously affected in the Mansuar (Besar and Kecil/Kri) area. 2016-2015 was a massive turning point, with lots of homestays built in the area which once only hosted Max Ammer's Kri-Eco and Sorido resorts, and very fast.
Trees near the shoreline were cut, structrues were built (there was even a plan to build a pool at some point...) and in only a few months you could see silting and algae growth in the shallow "house-reefs" around the island, linked to run-off from from rainwater no longer held by the treeline and also waste water from the new infrastructures (notably showers and toilets)...

Coral colonies in the area are/were believed to have evolved to better withstand heat-stress (not sure where the research on the subject is at now), but combined with stress from infrastructure and activity development, it's quite a lot.
Add to that snorkeler/diver damage (seeing an overweighted "discover-scuba diver" smash a table coral in front of my eyes at Yenbuba, or the growing effect of fin-kicks-and-chill on the often current-swept top of a site like Blue Magic come to mind...) to the now unavoidable global emission-related emergency (difficult to reach Raja Ampat without flying to Sorong from somewhere, unfortunately...), trash, plastic, oil and the rest (no, let's not talk about that cruise-ship smashing into the reef at Crossover...) and there are a lot of reasons to be worried for what is still often marketed as "The Last Paradise©"

It's something that also struck me in less remote areas like Bali's booming Amed for instance, where over-construction and associated waste-water is rapidly killing of what is left of the reef in the area.

What was that saying about being in traffic or being traffic again? 😐

cheers
