Coral Reef Futures Forum

by John Quiggin on October 20, 2007

I spent the last couple of days in Canberra at the Coral Reef Futures Forum, as part of my new Federation Fellowship is to look at economic approaches to management of the Great Barrier Reef. As one of the speakers said, a lot of the talks had people staring at their shoes in gloom, though the tone got a little more positive towards the end. I’m an optimist on ecological issues which is fortunate, because when you look at the threats facing coral reefs, you need a lot of optimism. Looking at historical data, even the GBR, which is much better managed than most reef systems is significantly degraded relative to 100 years ago, and a large proportion of reefs are at or near the point of no return, thanks to overfishing, destructive fishing methods and marine pollution. When you add regular bleaching due to climate change, and also acidification due to higher CO2 levels, the chances of saving much of the world’s coral reef systems do not look too good.

The most hopeful view is that, if we can fix the local threats like overfishing and poor water quality, the resulting increase in resilience (part of my project is to develop a more rigorous understanding of this popular buzzword) will offset moderate global warming, so that if we can stabilise the climate (an increase of no more than 2 degrees) we might save at least some reef systems.
