The is quite a bit of buzz today about recent research that quantifies how much whaling has – and is – contributing to atmospheric carbon. It appears that whales store significant amounts of carbon. I doubt, however, we will ever have a global breeding program to increase our whale populations, thereby offsetting our own carbon emissions. It’s just not feasible. (Besides, encouraging more people-whale interactions isn’t a popular idea at the moment.)
The focus needs to be broadened beyond whales. Ocean habitats are continually overlooked by the global community as viable sites of carbon sequestration. Blue carbon – as some call it – is a new concept being researched by the NGO community and receiving blog hits. The New York Times has even taken notice. Three months ago, Dan Laffoley of IUCN wrote a wonderful NYT op-ed entitled, To Save the Planet, Save the Seas. Read it.
In short, blue carbon emphasizes the key role of marine and coastal ecosystems. It places value on carbon-rich marine vegetation such as mangrove forests, seagrass, brackish marshes and salt marshes. Coastal and marine ecosystems are believed to be able to complement the role of forests in taking up carbon emissions through sequestration.
This is a management area that was greatly overlooked in Copenhagen. It’s a concept to which the UN and coastal nations ought to give more attention. Island nations rich in blue carbon, like Indonesia, could benefit similarly to the way Brazil is predicted to benefit from “green carbon” sequestration programs, like REDD.
In my opinion, blue carbon sequestration programs will need new research, the right political advocates, and better governance. The question I pose to you marine scientists/environmental managers/policy makers: Where to start?
