A convenient truth: global push for carbon-based conservation

19 05 2014

Eucalyptus viminalis (Manna Gum) - leaf, adultI’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 »





Australian League of Environmental Organisations

Shades of Green

ALEO – the acronym has a nice ring to it. Although I must confess that said organisation doesn’t yet exist, but it bloody well should.

Australia is in dire need of a united front to tackle the massive anti-environment sentiment gripping this country’s band of irresponsible and short-sighted libertarian politicians. Only yesterday I was chatting to a student in the tea room about my ‘State of South Australia’s Environment‘ talk when he asked “So, what can we do about it?”. Isn’t that the 1 per cent1 question?

Apart from the obvious: (1) keep up the pressure on bad government plans (petitions, letters, blogs, reports, e-mails), (2) don’t vote for the Coalition and (3) if you’re a scientist, place some economic or well-being value on environmental processes so that even politicians can understand that maintaining ecosystems makes good economic sense, I almost casually mentioned that we need a united front in Australia against this latest right-wing wave of anti-environmentalism.

I’ve thought about this before, but my latest conversation got me reflecting on the problem a little more – why don’t we have a united league of environmental organisations in Australia? Read the rest of this entry »





South Australia’s tattered environmental remains

State budget percentage expenditures for health, education and environment

South Australia State budget percentage expenditures for health, education and environment

Yesterday I gave the second keynote address at the South Australia Natural Resource Management (NRM) Science Conference at the University of Adelaide (see also a brief synopsis of Day 1 here). Unfortunately, I’m missing today’s talks because of an acute case of man cold, but at least I can stay at home and work while sipping cups of hot tea.

Many people came up afterwards and congratulated me for “being brave enough to tell the truth”, which both encouraged and distressed me – I am encouraged by the positive feedback, but distressed by the lack of action on the part of our natural resource management leaders.

The simple truth is that South Australia’s biodiversity and ecosystems are in shambles, yet few seem to appreciate this.

So for the benefit of those who couldn’t attend, I’ve uploaded the podcast of my slideshow for general viewing here. I’ve also highlighted some key points from the talk below: Read the rest of this entry »





Eye on the taiga

24 03 2014

boreal damageDun! Dun, dun, dun! Dun, dun, dun! Dun, dun, daaaaah!

I’ve waited nearly two years to do that, with possibly our best title yet for a peer-reviewed paper: Eye on the taiga: removing global policy impediments to safeguard the boreal forest (recently published online in Conservation Letters).

Of course, the paper has nothing to do with cheesy Eighties music, underdog boxers or even tigers, but it does highlight an important oversight in world carbon politics. The boreal forest (also known as taiga from the Russian) spans much of the land mass of the Northern Hemisphere and represents approximately one quarter of the entire planet’s forests. As a result, this massive forest contains more than 35% of all terrestrially bound carbon (below and above ground). One doesn’t require much more information to come to the conclusion that this massive second lung of the planet (considering the Amazon the first lung) is a vital component of the world’s carbon cycle, and temperate biodiversity.

The boreal forest has been largely expanding since the retreat of the glaciers following the Last Glacial Maximum about 20,000 years ago, which means that its slow progression northward has produced a net carbon sink (i.e., it takes up more atmospheric carbon that it releases from decomposition). However, recent evidence suggests that due to a combination of increased deforestation, fire from both human encroachment and climate change, mass outbreaks of tree-killing insects and permafrost melting, the boreal forest is tipping towards becoming a net carbon source (i.e., emitting more carbon into the atmosphere than it takes up from photosynthesis). This is not a good thing for the world’s carbon cycle, because it means yet another positive feedback that will exacerbate the rapid warming of the planet. Read the rest of this entry »





If biodiversity is so important, why is Europe not languishing?

17 03 2014

collapseI don’t often respond to many comments on this blog unless they are really, really good questions (and if I think I have the answers). Even rarer is devoting an entire post to answering a question. The other day, I received a real cracker, and so I think it deserves a highlighted response.

Two days ago, a certain ‘P. Basu’ asked this in response to my last blog post (Lose biodiversity and you’ll get sick):

I am an Indian who lived in Germany for quite a long period. Now, if I am not grossly mistaken, once upon a time Germany and other west european countries had large tracts of “real” forests with bears, wolves, foxes and other animals (both carnivore and herbivore). Bear has completely disappeared from these countries with the advent of industrialization. A few wolves have been kept in more or less artificially created forests. Foxes, deer and hares, fortunately, do still exist. My question is, how come these countries are still so well off – not only from the point of view of economy but also from the angle of public health despite the loss of large tracts of natural forests? Or is it that modern science and a health conscious society can compensate the loss of biodiversity.

“Well”, I thought to myself, “Bloody good question”.

I have come across this genre of question before, but usually under more hostile circumstances when an overtly right-wing respondent (hell, let’s call a spade a spade – a ‘completely selfish arsehole’) has challenged me on the ‘value of nature’ logic (I’m not for a moment suggesting that P. Basu is this sort of person; on the contrary, he politely asked an extremely important question that requires an answer). The comeback generally goes something like this: “If biodiversity is so important, why aren’t super-developed countries wallowing in economic and social ruin because they’ve degraded their own life-support systems? Clearly you must be wrong, Sir.”

There have been discussions in the ecological and sustainability literature that have attempted to answer this, but I’ll give it a shot here for the benefit of CB.com readers. Read the rest of this entry »





Lose biodiversity and you’ll get sick

14 03 2014

dengueHere’s a (paraphrased) recommendation I did recently for F1000 about a cool avenue of research I’ve been following for a few years now. Very interesting, but much, much more to do.

The core concepts of conservation ecology are well-established: we know that habitat lossfragmentation, invasive species, over-exploitation and of course, climate change, are bad for biodiversity. This well-quantified scientific baseline has led the discipline recently to embark on questions pertaining more to the (a) implications of biodiversity loss for humanity and (b) what we can do to offset these. A recent paper by Morand and colleagues addresses perhaps one of the most compelling reasons that human society should appreciate biodiversity beyond its intrinsic value; as biodiversity degrades, so too does human health.

Some argue that the only way to convince society in general that biodiversity is worth protecting is that we link its loss directly to degrading human health, wealth and well-being. Confirmation of such relationships at a variety of spatial and temporal scales is therefore essential. Morand and colleagues used data from a variety of sources to test two predictions: (1) that the number of infectious disease should increase as overall biodiversity increases and (2) that biodiversity loss, inferred from species threat and deforestation data, should increase the number of infectious disease outbreaks in humans. Using data from 28 countries in the Asia-Pacific region, they confirmed both predictions. Read the rest of this entry »





Alliance of Leading Environmental Researchers and Thinkers

11 03 2014

ALERTIf you’ve been following this blog or my Twitter feed over the last few weeks, you’ve surely noticed a few references to A.L.E.R.T. – the Alliance of Leading Environmental Researchers and Thinkers. You might also have asked yourself, what exactly is ALERT, and is it something I should pay attention to?

Today’s post attempts to explain this new organisation, and hopefully convince you that the answer to the second question is ‘yes’.

Several months ago, a slightly cryptic e-mail from eminent conservation biologist, Bill Laurance, arrived in my inbox. It asked – what do you think of this logo (see associated image)? A few e-mails later and a couple of minor tweaks, and we ended up with what I thought was a pretty cool logo for this new ‘ALERT’ thing. It wasn’t until quite some time later that I finally understood what Bill was attempting to create.

Is ALERT a news aggregator, a blog, an advocacy group, a science-communication resource or a science-policy interface? Why, yes it is!
