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 »

A carbon economy can help save our species too

20 05 2013

We sent out this media release the other day, but it had pretty poor pick-up (are people sick of the carbon price wars?). Anyway, I thought it prudent to reprint here on CB.com.

Will Australia’s biodiversity benefit from the new carbon economy designed to reduce greenhouse gas emissions? Or will bio-‘perversities’ win the day?

“Cautious optimism” was the conclusion of Professor Corey Bradshaw, Director of Ecological Modelling at the University of Adelaide’s Environment Institute. He is lead author of a new paper published in the journal of Biological Conservation which reviewed the likely consequences of a carbon economy on conservation of Australian biodiversity.

“In most circumstances these two very important goals for Australia’s future – greenhouse gas emissions reduction and biodiversity conservation – are not mutually exclusive and could even boost each other,” Professor Bradshaw says.

“There are, however, many potential negative biodiversity outcomes if land management is not done with biodiversity in mind from the outset.”

The paper was contributed to by 30 Australian scientists from different backgrounds. They reviewed six areas where Australia’s Carbon Farming Initiative could have the greatest impact on biodiversity: environmental plantings; policies and practices to deal with native regrowth; fire management; agricultural practices; and feral animal control.

“The largest biodiversity ‘bang for our buck’ is likely to come from tree plantings,” says Professor Bradshaw. “But there are some potential and frightening ‘bioperversities’ as well. For example, we need to be careful not to plant just the fastest-growing, simplest and non-native species only to ‘farm’ carbon.

“Carbon plantings will only have real biodiversity value if they comprise appropriate native tree species and provide suitable habitats and resources for valued fauna. Such plantings could however risk severely altering local hydrology and reducing water availability.”

Professor Bradshaw says carefully managing regrowth of once-cleared areas could also produce a large carbon-sequestration and biodiversity benefit simultaneously. And carbon price-based modifications to agriculture that would benefit biodiversity included reductions in tillage frequency, livestock densities and fertiliser use, and retention and regeneration of native shrubs.

Costs and benefits of a carbon economy for conservation

12 06 2012

I’ve had the good fortune of being involved now in a several endeavours funded by the Australian Centre for Ecological Analysis and Synthesis (ACEAS); two of those were workshops targeting specific questions regarding estimating modern extinction rates and examining the effects of genetic bottlenecks on Australian biota. The third was a bit different, to say the least – it was a little along the lines of ‘build it, and they will come‘. In other words, what happens when you bung 40 loosely associated researchers in a room for two days? Does anything of substance result, or does it degenerate into a mere talk-fest. I’m happy to say the former. The details of the ACEAS ‘Grand Workshop‘ are now being finalised in a paper that should be submitted by the end of the month. The ACEAS report is reproduced below.

The Grand ACEAS Workshop was something of an experiment: what will happen when we bring 30 of Australia’s top scientists working on land management issues into the same room?

The Grand Workshop participants came from academia, research institutions and the government, and had all received ACEAS funding for working groups. David Keith, Ted Lefroy, Jasmyn Lynch, Wayne Meyer and Dick Williams were amongst the attendees of the two-day workshop.

And when this group of people came together wanting to analyse and synthesise ecological data, great things happened.

“We decided to focus on how carbon pricing legislation will affect land use change and how will that spill over into biodiversity persistence”, said Professor Corey Bradshaw, Director of Ecological Modelling at The University of Adelaide, who led the synthesis activity at the Grand ACEAS Workshop.

“Will carbon pricing lead to good outcomes for biodiversity, or negative ones, or will it have no bearing whatsoever?”

The workshop participants broke into five groups to discuss how the carbon tax legislation will change land use when it is introduced in July 2012, and the potential impact on biodiversity.

Some of the questions asked included:

Is it enough simply to allow plants to re-grow to be eligible for carbon credits?
How will an increase in forestry plantations impact biodiversity, water catchments and fire regimes?
Will there be more kangaroo grazing to reduce methane emissions and erosion, replacing hard-hoofed livestock?
Can you receive carbon credits for shooting large feral animals like goats, camels, deer and boars?

The groups found many opportunities for positive biodiversity outcomes with the carbon sequestration activities encouraged by carbon pricing, but there are also many potential ‘bio-perversities’. Read the rest of this entry »

Humans suddenly become intelligent

1 04 2012

Some described it as the “eco-topia”; some believed they had died in the night and awoken in a different universe. Some just stood there gaping stupidly.

Yet the events of 01 April 2012 are real*. Humans suddenly became intelligent.

In an unprecedented emergency UN session this morning, all the world’s countries pledged to an immediate wind-down of the fossil-fuel economy and promised to invest in a rational combination of nuclear and renewable energy sources. Some experts believe the pledge would see a carbon-neutral planet by 2020.

Additionally, the session saw a world-wide pledge to halt all deforestation by 2013, with intensive reforestation programmes implemented immediately.

Family planning would be embraced worldwide, with a concerted effort to see the human population plateau by 2070, and begin declining to a stable 2 billion by 2300. Read the rest of this entry »

Australian ecologists support carbon tax

18 07 2011

Last week I came across a report that 60 % of economists support the newly proposed Australian carbon tax initiative, and that most believed the Coalition’s plan was inferior and would likely be more costly.

I thought that it would be good to survey ecologists on this very same issue because we are the people dealing with the fall-out of climate change to natural systems, and we are the group communicating it and its consequences to the greater public. Climate change effects on the Australian biota are already being witnessed, and if we don’t take the lead in this over-populated world of myopic, self-interested growth addicts, it’s our children who will suffer most.

Usually, ecologists and economists tend to disagree on major policies because of the general view that development is incompatible with functioning ecosystems; however in this case, it’s telling that the two seem to agree. If economists and ecologists together support something, it’s probably a good idea to give it a go. Read the rest of this entry »

Do ecologists support Australia’s new carbon tax?

13 07 2011

Today on The Conversation, it was reported that 60 % of 145 economists surveyed support Australia’s new Carbon Tax scheme.

I am wondering what kind of support there is for it out there amongst ecologists. If you are one, please complete the following short survey by clicking here.

I’ll post the results in a few days.
