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

12 03 2013

carbon farming 2I’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 »





Toothed conflict

Another corker from Salva. He’s chosen a topic this week that’s near and dear to my brain – the conservation of higher-order predators. As ConBytes readers will know, we’ve talked a lot about human-predator conflict and the inevitable losers in that battle – the (non-human) predators. From dingos to sharks, predator xenophobia is just another way we weaken ecosystems and ultimately harm ourselves.

Rural areas devoted to livestock are part of the natural landscape, so it is inevitable (as well as natural) that predators, livestock and humans interact in such a mosaic of bordering habitats. However, their coexistence remains an unresolved conservation problem. 

When two species, people, political parties, enterprises… want the same thing, they either share it (if possible) or one side eliminates the competitor. The fact that proteins are part of the diet of humans and other carnivore species has resulted in a trophic drama that goes back millennia. Nowadays, predators like eagles, coyotes, lions, wolves and raccoons are credited for attacks on cattle and poultry (and people!) in all continents. This global problem is not only economic, but interlaces culture, emotion, policy and sanitation (1-4). For instance, some carnivores are reservoirs of cattle diseases and contribute to pathogen dispersal (5, 6).

Management options

Managers of natural resources have implemented three strategies to handle these sorts of issues for livestock breeders in general (7). Those strategies can be complementary or exclusive on a case-by-case basis, and are chosen following cost-benefit assessments and depending on the conservation status of the predator species involved. (i) ‘Eradication’ aims to eliminate the predator, which is regarded as noxious and worthless. (ii) ‘Regulation’ allows controlled takes under quota schemes, normally for pre-defined locations, dates and killing methods. ‘Preservation’ is applied in protected areas and/or for rare or endangered species, and often requires monitoring and measures set to prevent illegal harvest or trade. Additionally, many livestock breeders receive money to compensate losses to predators (8).

Many experts now advocate non-lethal (preventive) measures that modify the behaviour of people, livestock or predators (2, 7). The use of livestock-guarding dogs is one of those preventive measures (9). As an example, Laurie Marker (director of the Cheetah Conservation Fund) et al. (10) studied the use of 117 Anatolian shepherds adopted by Namibian rangers between 1995 and 2002 (Fig. 1). In this African country, cheetahs (Acinonyx jubatus) selectively forage on small-sized cattle and juveniles. Despite this feline being protected nationally, Namibian laws authorise rangers to shoot cheetahs in situations of risk to people and their properties, with more than 6,000 cheetahs having been killed in the 1980s alone (11). Through face-to-face interviews, Marker found that since the arrival of the Anatolian shepherds, > 70 % of the rangers perceived a pronounced reduction in cattle mortality (10). Although, the use of livestock-guarding dogs has worked out fine in many places worldwide, it is no panacea. In many other instances, the dogs dissuade some predator species and not others from harassing the livestock, or are only effective in combination with other measures (7, 9).

Degraded States of Ausmerica

20 08 2012

You might remember that I’ve been in California for several weeks now. The principal reason for my visit was to finish a book that Paul Ehrlich and I started last year. So, without the major distractions of everyday university life, I’ve spent much of my time lately at Stanford University in a little office next to Paul’s trying to finish (I also attended a conference in Portland, Oregon).

Yesterday, we wrote the last few paragraphs. A giant gorilla has now lumbered its way off my back.

So. What is the book about, you might ask? I can’t give away too many details, but I will give a few teasers. The book is called, at least for now, ‘Oz & US’, which is a bit of a play of words. In the book we contrast the environmental histories, current state of affairs, and likely futures of our respective nations. It’s written in a popular style so that non-specialists can learn a little something about how bad the environment has become in our two countries.

At first glance, one might wonder why we chose to contrast the U.S. and Australia – they are quite different beasts, indeed. Their histories are immensely different, from the aboriginal populations, through to European colonisation (timing and drivers), biological (including agricultural) productivities, carrying capacities, population sizes and politics. But these differences belie too many convergences in the environmental states of each nation – we now both have increasingly degraded environments, we have both pushed the boundaries of our carrying capacities, and our environmental politics are in a shambles. In other words, despite having started with completely different conditions, our toll on nature’s life-support systems is now remarkably similar.

And anyone who knows Paul and me will appreciate that the book is completely irreverent. We have taken off the gloves in preparation for a bare-knuckle fight with the plutocrats and theocrats now threatening the lives of our grandchildren. We pull no punches here. Read the rest of this entry »





The invisible hand of ecosystem services

4 08 2012

I’ve just spent nearly an entire week trying to get my head around ecosystem services (ES).

You’d think that would have been a given based on my experience, my research, my writings and the fact that I’ve just spent the last week with 400 ES specialists from around the world at the 5th international Ecosystem Services Partnership (ESP) Conference in Portland, Oregon, USA.

Well, prior to this week I thought I knew what ES were, but now I think I’m just a little more confused.

Of course, I’m not talking about the concept of ES or what they are (hell, I’ve written enough about them on this blog and in my papers); my problem is understanding how we as society end up valuing them in a practical, sensible and feasible way.

So I’m going to describe the ESP Conference as I saw it, and not necessarily in chronological order.

First up is the term ‘ecosystem services’ itself – horrible name, and something rammed home again after attending the conference. Most people on the planet that are not scientists (that would be nearly everyone) just might have the most tenuous and ethereal of grasps of ‘ecosystem’ in the first place, and I’d bet that 99 % of most undergraduate students couldn’t provide a comprehensive description. This is because ecosystems are mind-bogglingly, chaotically and awesomely complex. Just ask any ecosystem ecologist.

The second part of the term – services – is particularly offensive in its presumption and arrogance. It’s not like you ring up an ecosystem and get it to clean your carpets, or fill your water tank or gas cylinder. No, the natural world did not evolve to pamper humanity; we are merely part of it (and bloody efficient at modifying it, I might add).

So try to sell this ‘incredibly complex thingy’ that is ‘there to do some (intangible) shit for us’ to the public, policy makers and politicians, and you mostly get a dog’s regurgitated breakfast and some blank, slack-jawed stares. 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 »





Get boreal

7 06 2012

I’ve been a little quiet this last week because I’ve had to travel to the other side of the planet for what turned out to be a very interesting and scientifically lucrative workshop. After travelling 31 hours from Adelaide to Umeå in northern Sweden, I wondered to myself if it was going to be worth it for a 2.5-day workshop on a little island (Norrbyskär) in the Baltic Sea (which, as it turned out, didn’t have internet access).

The answer is a categorical ‘yes’!

Many of you know that I’ve dabbled in boreal forest conservation in the past, but I could never claim any real expertise in the area. Hence it came as something of a shock when Jon Moen of Umeå University asked me to attend a specialist workshop focused loosely on making the plight and importance of the boreal forest more widely acknowledged. I dragged my feet initially, but Jon convinced me that I could add something to the mix.

It was a small workshop, but well-represented by all boreal countries save Norway (i.e., we had Russians, Swedes, Finns, Canadians and Americans – this Australian was indeed the odd one out). We also had a wide array of expertise, from carbon accountants, political scientists, political economists, native cultures experts, ecologists to foresters. Our mandate – justify why we should pay more attention to this globally important region.

Just how important is the boreal forest? We managed to unearth some little-appreciated facts: Read the rest of this entry »





Worlds collide: greenwashed development to kill biodiversity

15 03 2012

Another development fiasco that, if it goes ahead, will devastate a Biodiversity Hotspot and ultimately, reduce the livelihood prospects of millions of West Africans.

In yet another move to expose and shame the greedy developers behind another massive (and superlatively greenwashed) oil palm development in the tropics (see our previous Open Letter), Bill Laurance and Josh Linder have organised another Open Letter from some of the world’s top conservation scientists (again, I count myself fortunate to be included in that group) denouncing the project. The press release is below, followed by the letter itself:

Eleven of the world’s top scientists have produced an open letter to the public urging the Cameroon government to stop a giant oil palm plantation that they say will threaten some of Africa’s most important protected areas.

The project, sponsored by a subsidiary of U.S. agribusiness giant Herakles Farms in collaboration with a U.S. nonprofit organization, All for Africa, would span 70,000 hectares (154,000 acres), an area nearly the size of New York City.

“It’s simply frightening in scope,” said Thomas Struhsaker, a leading expert on African primates and rainforest ecology at Duke University in North Carolina, USA, who has worked in the region for nearly a half-century.

The project would destroy a critical forested area that currently links five national parks or protected areas in Cameroon, say the scientists.

“These forests are vital for wildlife, including the African elephant, chimpanzee and drill, all threatened or endangered species,” said anthropologist Joshua Linder of James Madison University in Virginia, USA, who has helped coordinate the protest. “These animals rely on the forests that would be destroyed to survive and move among the parks.”

“This area is a biodiversity hotspot, some of the world’s most biologically important real estate,” said tropical ecologist William Laurance of James Cook University in Australia, who studies threats to wildlife in the Congo Basin.

“There’s no way a project like this would be allowed in most countries, because the price for biodiversity is just too high,” said Laurance.

The project has been promoted in Cameroon as environmentally sustainable, but the scientists heatedly disagree. “Those promoting this project are misleading everyone—especially the people and government of Cameroon,” said Linder. “They claim the forests they want to clear are mostly logged and degraded, but we’ve shown clearly that they include lots of tall, dense forest that’s vital for wildlife and nature conservation.” Read the rest of this entry »





Unholy trinity of leakage, permanence and additionality

13 03 2012

I begin with the proverbial WTF? The title of this post sounds a little like the legalese accompanying a witchcraft trial, but it’s jargon that’s all the rage in the ‘trading-carbon-for-biodiversity’ circles.

I’m sure that most of my readers will have come across the term ‘REDD‘ (Reduced Emissions from Deforestation and forest Degradation), which is the clever idea of trading carbon credits to keep forests intact. As we know, living forests can suck up a lot of carbon from the atmosphere (remember your high school biology lesson on photosynthesis? Carbon dioxide in. Oxygen out), even though climate change is threatening this invaluable ecosystem service. So the idea of paying a nation (usual a developing country) to protect its forests in exchange for carbon pollution offsets can potentially save two birds with one feeder – reducing overall emissions by keeping the trees alive, and ensuring a lot of associated biodiversity gets caught up in the conservation process.

The problem with REDD though is that it’s a helluva thing to bank on given a few niggly problems essentially revolving around trust. Ah yes, the bugbear of any business transaction. As the carbon credit ‘buyer’ (the company/nation/individual who wishes to offset its carbon output by ‘buying’ the carbon uptake services provided by the intact forest), you’d want to make damn sure that all the money you spend to offset your carbon actually does just that, and that it doesn’t just end up in the hands of some corrupt official, or even worse, used to generate industry that results in even higher emissions! As the buyer, of course you want to entice investors to give you lots of money, and if you bugger up the transaction (by losing the resource you are providing), you’re not likely to have any more investors coming knocking on your door.

Enter the unholy trinity of leakage, permanence and additionality.

This horrible jargon essentially describes the REDD investment problem:

Knowledge slavery

29 01 2012

Another workshop; another productive week.

As many readers will know, I’ve spent the last week in the mountains north of Madrid working on a series of conservation ecology papers with host Miguel Araújo (of the Integrative Biology and Global Change Group at the Spanish National Museum of Natural Sciences), my lab colleagues, Barry Brook, Damien Fordham and Salvador Herrando-Pérez, and Miguel’s post-doc, Regan Early.

Let me tell you, staying in the craggy granite Sierra de Guadarrama mountains at a well-known health spa eating explosively flavourful Spanish food and drinking an immodest selection of the region’s delicious wines, is particularly conducive to scientific productivity (yes, I AM a jammy tart). Although unlikely to be followed by many (even if they have the means), I highly recommend the experience for those suffering from writer’s block.

But this post isn’t about the scenery, food, wine, hydrothermal treatment or even the content of the workshop at all (I just prefaced it as such to gloat); it’s about a particularly sore point for me and hundreds of thousands of other scientists the world over – our slavery to the scientific publishing industry.

And ‘slavery’ is definitely the most appropriate term here, for how else would you describe a business where the product is produced by others for free1 (scientific results), is assessed for quality by others for free (reviewing), is commissioned, overviewed and selected by yet others for free (editing), and then sold back to the very same scientists and the rest of the world’s consumers at exorbitant prices.

This isn’t just a whinge about a specialised and economically irrelevant sector of the economy, we’re talking about an industry worth hundreds of billions of dollars annually. In fact, Elsevier (agreed by many to be the leader in the greed-pack – see how some scientists are staging their protest; also here) made US$1.1 billion in 2010! Read the rest of this entry »





Cartoon guide to biodiversity loss XIV

The last post of 2011, I thought I’d focus on the lighter side (that is to say, my brain is muddled by the lovely break from academia, so I don’t really feel like investing too much cerebral energy). Here, therefore, are the latest six cartoons… (see full stock of previous ‘Cartoon guide to biodiversity loss’ compendia here). May fewer species go extinct in 2012 than 2011…

Mucking around the edges

8 11 2011

Barry Brook over at BraveNewClimate.com beat me to the punch regarding our latest paper, so I better get off my arse and write my take on things.

This post is about a paper we’ve just had accepted and has come out online in Biological Conservation called Strange bedfellows? Techno-fixes to solve the big conservation issues in southern Asia - and it’s likely to piss off a few people, and hopefully motivate others.

We wrote the paper for a special issue of essays dedicated to the memory of our mate and colleague, Navjot Sodhi, who died earlier this year. The issue hasn’t been released yet, but we have managed to get our paper out well before.

Like Navjot, the paper is controversial. Also like Navjot, we hope it challenges a few minds and pushes a few boundaries. We, as conservation biologists, must accept the fact that we have largely failed – biodiversity is still being lost at an alarming rate despite decades and decades of good science, sound evidence-based policy recommendations and even some rescues of species on the ‘brink’. Huge consumption rates, a population of 7 billion humans and counting, carbon emissions exceeding all worst-case scenarios, and greater disparity of wealth distribution have all contributed to this poor performance.

So what else can we do? Read the rest of this entry »

The rarity paradox

22 06 2011

© C. Madden

My friend and colleague at the Centre National de Recherche Scientfique (CNRS), Laboratoire d’Ecologie Systématique & Evolution based at the Université Paris-Sud in France, Dr. Franck ‘Allee EffectCourchamp, has asked me to help him out finding a suitable candidate for what sounds like a very cool job. If you’re in the market for a very interesting and highly relevant conservation post-doctoral fellowship, please read on.

And even if you’re not looking for a position, but are interested in the anthropogenic Allee effect, then by all means, please read on as well.

This two-year fellowship is part of a grant focused on demonstrating the novel rarity paradox, either in new wildlife trade markets (i.e., exotic pets, traditional medicine, et cetera) or in newly exploited species (e.g., tibetan antilope, seahorses, et cetera). Read the rest of this entry »

Infinite planet theory

24 05 2011

Rob Dietz over at the Centre for the Advancement of the Steady State Economy (CASSE) just e-mailed me and suggested I reproduce a recent post of theirs on ConservationBytes.com. Rob has produced a cracker – very funny, but ‘reality’ usually is. Many thanks, Rob, for a fine piece of writing.

Few people have read the dense volumes published by the economist Milton Mountebank, but his work has affected you, me and every single person on the planet. Dr. Mountebank has revolutionized economic thought, and now he has been recognized for his singular efforts. Yesterday at a gala reception in Stockholm, Sweden, the chairman of Sveriges Riksbank, Peter Norborg, presented Dr. Mountebank with the Nobel Prize in Economics for his lifetime of work on infinite planet theory.

In his presentation of the award, Mr. Norborg stated, “Dr. Mountebank has demonstrated imagination and inventiveness beyond what the rational mind can comprehend.” Indeed, it is because of his theories that we all do what we do economically. Nations strive for continuous GDP growth and endless expansion of consumption thanks to infinite planet theory. Mr. Norborg went on to say, “All of our banks, including Sveriges Riksbank, owe him a huge debt. We finance economic expansion. Our actions and decisions would be morally suspect if we lived on a finite planet.”

In a light-hearted moment during the presentation, Mr. Norborg asserted that Dr. Mountebank had provided an even greater service to humanity by reducing stress on individuals. “Best of all,” he said, “is that we can extract, consume and digest resources guilt-free. Planetary constraints have been conquered. They have gone the way of the dodo, the Roman Empire and the world’s major fisheries.” Read the rest of this entry »
