A convenient truth: global push for carbon-based conservation

19 05 2014

I’ve just written an article for the Australian River Restoration Centre‘s RipRap magazine, and they have given me permission to reproduce it here.

The brave, new green world of the carbon economy hasn’t exactly taken off as desired. Perhaps it’s because it wasn’t really planned from the outset, or maybe it is still too abstract for most people to accept, digest and incorporate into their daily lives. An emergent property of society’s generally slow awakening to the challenge of climate disruption, is that it will be a long time before we accept its full suite of incarnations.

The infant carbon economy is, however, well and truly alive and kicking, so it is important to try and plan for its growing influence on our decision making. Bumps in the road aside, the carbon economy has mostly been a blessing (actual and potential) for biodiversity conservation projects the world over.

In principle, the aim of the carbon economy is rather straight-forward: charge people a certain amount for each unit of carbon dioxide equivalents they release, and then use that money to develop approaches that further increase carbon sequestration or limit emissions. It’s a ‘build-it-and-they-will-come’ framework, where increasing financial impetus to restrict emissions is enhanced by society’s evolution towards better approaches and technology.

The operational side of the carbon economy is unfortunately much more muddled, with vested interests and political gaming weakening its implementation. Nonetheless, we persevere. Read the rest of this entry »

Brave new green world: biodiversity’s response to Australia’s carbon economy

12 03 2013

I’ve had a busy weekend entertaining visiting colleagues and participating in WOMADelaide‘s first-ever ‘The Planet Talks‘. If you haven’t heard of WOMADelaide, you’re truly missing out in one of the best music festivals going (and this is from a decidedly non-festival-going sort). Planet Talks this year was a bit of an experiment after the only partially successful Earth Station festival held last year (it was well-attended, but apparently wasn’t as financially successful as they had hoped). So this year they mixed a bit of science with a bit of music – hence ‘Planet Talks’. Paul Ehrlich was one of the star attractions, and I had the honour of going onstage with him yesterday to discuss a little bit about human population growth and sustainability. It was also great to see Robyn Williams again. All the Talks were packed out – indeed, I was surprised they were so popular, especially in the 39-degree heat. Rob Brookman, WOMADelaide’s founder and principal organiser, told me afterward that they’d definitely be doing it again.

But my post really isn’t about WOMADelaide or The Planet Talks (even though I got the bonus of meeting one of my favourite latin bands, Novalima, creators of one of my favourite songs). It’s instead about a paper I heralded last year that’s finally been accepted.

In early 2012 at the Terrestrial Ecosystem Research Network (TERN) symposium in Adelaide, the Australian Centre for Ecological Analysis and Synthesis (ACEAS) put on what they called the ‘Grand Challenges’ workshop. I really didn’t get the joke at the time, but apparently the ‘grand challenge’ was locking 30 scientists with completely different backgrounds in a room for two days to see if they could do anything other than argue and bullshit. Well, we rose to that challenge and produced something that I think is rather useful.

I therefore proudly introduce the paper entitled Brave new green world: consequences of a carbon economy for the conservation of Australian biodiversity just accepted in Biological Conservation. The online version isn’t quite ready yet (should be in the next few weeks), but you are welcome to request a preprint from me now. If you attended (the surprisingly excellent) TERN symposium in Canberra last month, you might have seen me give a brief synopsis of our results.

The paper is a rather in-depth review of how we, 30 fire, animal, plant, soil, landscape, agricultural and freshwater biologists, believe Australia’s new carbon-influenced economy (i.e., carbon price) will impact the country’s biodiversity. Read the rest of this entry »

Experiments in carbon-biodiversity trade-offs

19 07 2012

Last month I covered a topic that is not only becoming the latest fashion-trend in conservation, it is also where much of the research funding is going. Whether or not this is the best use of limited research resources is largely irrelevant – as I always preach to fledgling grant writers: “Write about what the funding agency wants to fund, not what you want to do”. Cynical, I know, but it is oh-so-true.

The topic in question is how we as conservation biologists ensure that the new carbon economy drives positive change for biodiversity, rather than the converse. Hell knows we really can’t afford for land-use change to get any worse for biodiversity; worldwide we are on trajectory for a mass extinction within our lifetime, so anything that potentially makes it worse should be squashed completely.

But it seems that land- and seascape changes that might arise from trading carbon (including carbon pricing) are on a knife-edge as far as biodiversity is concerned. I described this dilemma in my previous post, and I am happy to say that the manuscript arising is almost complete. Briefly, if we as a society decide to try to reduce greenhouse gas emissions and capture as much carbon as possible by altering land-use practices, then it is likely that our forests will become vast monocultures incapable of sustaining much biodiversity at all. In other words, there’s a balance to be struck between what is good for carbon sequestration and what is good for biodiversity. While not always mutually exclusive, neither are they mutually attainable goals. Read the rest of this entry »
