More things stay the same, more we retrogress

20 07 2016

obrazek_1idiommmmsmmWithin six months of Abbott and the Coalition seizing power in the 2013 Australian election, decades—if not centuries—of environmental damage and retrograde policies unfolded. But this was no run-of-the-mill incompetence and neglect by government—this was an all-out attack on anything with the merest whiff of environmental protection. The travesty is well-documented, from infamously axing both the carbon-pricing scheme and climate commission, eradicating Labor’s 80% emissions-reduction target by 2050, diluting the Renewable Energy Target, refusing to commit to enforcing the Illegal Logging Prohibition Act (fortunately, this is now law), defunding the only independent legal entity available to limit environmentally destructive development (Environmental Defenders Office), to even attempting to remove the rights of environmental groups to challenge development proposals (thankfully, that failed).

The Coalition’s backward and ineffectual climate change-mitigation policies alone are evidence enough for long-term damage, but their war on the environment in general means that even the future election of a more environmentally responsible government will not undo the damage quickly, if at all. As a result of these and other nearsighted policies, Australia remains one of the highest per-capita greenhouse-gas emitters on the planet, has one of the highest per-capita water uses of any nation, leads the world in mammal extinctions, continues to deforest its already forest-poor landscape, and is a society utterly unprepared to deal with the future challenges of a degraded planet.

What immigration means for Australia’s climate-change policies

12 06 2016

After dipping my foot into the murky waters of human population demography a few years ago, I’m a little surprised that I find myself here again. But this time I’m not examining what the future of the global human population might be and what it could mean for our environment; instead, I’m focussing on Australia’s population future and its implications for our greenhouse-gas emissions trajectories.

Just published in Asia and the Pacific Policy Forum1, my paper with long-time co-author Barry Brook is entitled Implications of Australia’s population policy for future greenhouse gas emissions targets. It deals with the sticky question of just how many people Australia can ‘afford’ to house. By ‘afford’ I mean several things, but most specifically in the context of this paper is by how much we need to reduce our per capita emissions to achieve future reduction targets under various immigration-rate scenarios.

In many ways Australia’s population is typical of other developed nations in that its intrinsic fertility (1.78 children/woman) is below replacement (which is itself ~ 2.1 children/female). Yet Australia’s population grew nearly twice (1.88×) as large from 1971 to 2014. It doesn’t take a genius to figure out that most of our population growth is due to net immigration.

In fact, between 2006 and 2014, Australia welcomed a net of 215,000 new people per year (this means that of all the permanent immigrants and emigrants, a ‘net’ of approximately 215,000 stayed each year), which represents about 1% of our total population size (that latter most likely just ticked over 24 million).

One-two carbon punch of defaunation

30 04 2016

1-2 punchI’ve just read a well-planned and lateral-thinking paper in Nature Communications that I think readers of CB.com ought to appreciate. The study is a simulation of a complex ecosystem service that would be nigh impossible to examine experimentally. Being a self-diagnosed fanatic of simulation studies for just such purposes, I took particular delight in the results.

In many ways, the results of the paper by Osuri and colleagues are intuitive, but that should never be a reason to avoid empirical demonstration of a suspected phenomenon because intuition rarely equals fact. The idea itself is straightforward, but takes more than a few logical steps to describe: Read the rest of this entry »





Most-Bestest Environment Minister in the World, Ever

4 04 2016
Our Most-Bestest Minister Ever

Our Most-Bestest Minister Ever (i.e., the bloke on the left; interestingly, the bloke on the right leads one of the few countries in the world with a higher per capita emissions rate than Australia)

Australia has an appalling environmental record — hell, I have even written an entire book on our sorry state of environmental affairs. Of course, environmental damage is a slow accumulation of bad political decisions, neglect, corruption, greed and society’s general I-couldn’t-give-a-shit attitude, but the record of our recent government demonstrates not just classic political buffoonery and neglect, but an outright attack on the environment.

So it was impossible to restrain a disgusted guffaw when, in February this year, our ‘Environment’ Minister won the coveted ‘Best Minister’ in the World award at the World Government Summit in Dubai by Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the United Arab Emirates and Ruler of Dubai.

Deserved ridicule aside, I was asked recently by The Conversation to contribute to a special report examining the profile performance of cabinet and shadow cabinet ministers, which is not only a responsibility I take seriously, but an honour to be able to provide a serious and objective appraisal of our Most-Bestest Minister Ever. My contribution dealt specifically with the environmental portfolio, so I appraised both the sitting Minister and the Shadow Minister. Judge for yourself based on their performances.

Biowealth

24 02 2016

frogWhile I’ve blogged about this before in general terms (here and here), I thought it wise to reproduce the (open-access) chapter of the same name published in late 2013 in the unfortunately rather obscure book The Curious Country produced by the Office of the Chief Scientist of Australia. I think it deserves a little more limelight.

As I stepped off the helicopter’s pontoon and into the swamp’s chest-deep, tepid and opaque water, I experienced for the first time what it must feel like to be some other life form’s dinner. As the helicopter flittered away, the last vestiges of that protective blanket of human technological innovation flew away with it.

Two other similarly susceptible, hairless, clawless and fangless Homo sapiens and I were now in the middle of one of the Northern Territory’s largest swamps at the height of the crocodile-nesting season. We were there to collect crocodile eggs for a local crocodile farm that, ironically, has assisted the amazing recovery of the species since its near-extinction in the 1960s. Removing the commercial incentive to hunt wild crocodiles by flooding the international market with scar-free, farmed skins gave the dwindling population a chance to recover.

redwoodConservation scientists like me rejoice at these rare recoveries, while many of our fellow humans ponder why we want to encourage the proliferation of animals that can easily kill and eat us. The problem is, once people put a value on a species, it is usually consigned to one of two states. It either flourishes as do domestic crops, dogs, cats and livestock, or dwindles towards or to extinction. Consider bison, passenger pigeons, crocodiles and caviar sturgeon.

As a conservation scientist, it’s my job not only to document these declines, but to find ways to prevent them. Through careful measurement and experiments, we provide evidence to support smart policy decisions on land and in the sea. We advise on the best way to protect species in reserves, inform hunters and fishers on how to avoid over-harvesting, and demonstrate the ways in which humans benefit from maintaining healthy ecosystems.

Getting your conservation science to the right people

22 01 2016

argument-cartoon-yellingA perennial lament of nearly every conservation scientist — at least at some point (often later in one’s career) — is that the years of blood, sweat and tears spent to obtain those precious results count for nought in terms of improving real biodiversity conservation.

Conservation scientists often claim, especially in the first and last paragraphs of their papers and research proposals, that by collecting such-and-such data and doing such-and-such analyses they will transform how we manage landscapes and species to the overall betterment of biodiversity. Unfortunately, most of these claims are hollow (or just plain bullshit) because the results are either: (i) never read by people who actually make conservation decisions, (ii) not understood by them even if they read the work, or (iii) never implemented because they are too vague or too unrealistic to translate into a tangible, positive shift in policy.

A depressing state of being, I know.

This isn’t any sort of novel revelation, for we’ve been discussing the divide between policy makers and scientists for donkey’s years. Regardless, the whinges can be summarised succinctly: Read the rest of this entry »





Australia’s motto: “Screw the environment!”

2 09 2015
Mmmmm! I love coal!

Mmmmm! I love coal!

An article originally posted on ALERT by April Reside (with permission to reproduce).

The Conservative Tony Abbott government in Australia is proposing alarming changes to Australia’s Environmental Protection and Biodiversity Conservation (EPBC) Act 1999 — a remarkable move that would prevent environment groups from challenging many damaging development projects.

This has all come to a head over the Carmichael Coal Mine — a plan to build a massive mine in central Queensland in order to export 60 million of tonnes of coal to India each year.

Coal, of course, is the dirtiest of all fossil fuels, and India’s plan to burn it by the shipload for electricity is bad news for the planet.

The Abbott government is in a tizzy after after a community organization, the Mackay Conservation Group, challenged the approval of the Carmichael Mine in Australia’s Federal Court.

The community group says Environment Minister Greg Hunt didn’t properly consider the impact the mine would have on two threatened species, the yakka skink and ornamental snake.

The mine site also sustains the largest population of the southern subspecies of the black-throated Finch, which is endangered.

The implications of the mega-mine go well beyond a few imperilled species. If the mine goes ahead, it will be one of the biggest in the world — and the emissions from burning its mountains of coal would cancel out all gains made from Australia’s current emissions-reduction strategy.

On top of the frightening precedent it would set, the Abbott government appears to be double-dealing. Read the rest of this entry »
