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 »





Outright bans of trophy hunting could do more harm than good

5 01 2016

In July 2015 an American dentist shot and killed a male lion called ‘Cecil’ with a hunting bow and arrow, an act that sparked a storm of social media outrage. Cecil was a favourite of tourists visiting Hwange National Park in Zimbabwe, and so the allegation that he was lured out of the Park to neighbouring farmland added considerable fuel to the flames of condemnation. Several other aspects of the hunt, such as baiting close to national park boundaries, were allegedly done illegally and against the spirit and ethical norms of a managed trophy hunt.

In May 2015, a Texan legally shot a critically endangered black rhino in Namibia, which also generated considerable online ire. The backlash ensued even though the male rhino was considered ‘surplus’ to Namibia’s black rhino populations, and the US$350,000 generated from the managed hunt was to be re-invested in conservation. Together, these two incidents have triggered vociferous appeals to ban trophy hunting throughout Africa.

These highly politicized events are but a small component of a large industry in Africa worth > US$215 million per year that ‘sells’ iconic animals to (mainly foreign) hunters as a means of generating otherwise scarce funds. While to most people this might seem like an abhorrent way to generate money, we argue in a new paper that sustainable-use activities, such as trophy hunting, can be an important tool in the conservationist’s toolbox. Conserving biodiversity can be expensive, so generating money is a central preoccupation of many environmental NGOs, conservation-minded individuals, government agencies and scientists. Making money for conservation in Africa is even more challenging, and so we argue that trophy hunting should and could fill some of that gap. Read the rest of this entry »





When science is ignored: Mauritius starts culling 18,000 threatened fruit bats

8 11 2015

JS7D2844aRrHere’s a depressing emergency post by Fabiola Monty.

I started working on this article to discuss how useful science is being ignored in Mauritius.

The Mauritian government has decided to implement a fruit bat cull as an ‘urgent response’ to the claims of huge economic losses by fruit farmers, a decision not supported by scientific evidence. We have now received confirmation in Mauritius through a local press communiqué that on 7 November 2015, The Mauritian Ministry of Agro Industry and Food Security in collaboration with the local Police Department and Special Mobile Force will start the culling of 18,000 bats in their natural habitats “with a view to reducing the extent of damages caused to fruits by bats”.

Tackling human-wildlife conflicts can indeed be challenging, but can the culling of 18,000 endemic Mauritian flying fox (Pteropus niger) resolve ‘human-wildlife conflict’ in the land of the dodo? In the case of Mauritius, scientific evidence not only demonstrates that the situation has been exaggerated, but that there are alternatives to bat culling that have been completely brushed aside by policy makers.

JS7D3726aRrAre the Mauritius fruit bats agricultural pests?

While fruit bats are being labelled as serious pests, scientific evidence shows instead that their impacts have been exaggerated. A recent (2014) study indicates that bats damage only 3-11% of fruit production, with birds also contributing to 1-8% of fruit loss. Rats are also probable contributors to fruit damage, but the extent remains unquantified. Interestingly, more fruits are lost (13-20%) because they are not collected in time and are left to over-ripen.

While the results of the study were communicated to legislators a few months before they made the decision to cull, it is clear that these were ignored in favour of preconceived assumptions.

Are there too many fruit bats? Read the rest of this entry »





Killing the Koala and Poisoning the Prairie

Cover-Bradshaw&Ehrlich-final

Man and the environment are meant for each other” — Tony Abbott, former Prime Minister of Australia (2014)

I know the human being and the fish can co-exist peacefully” — George W. Bush, former President of the USA (2000)

It. Has. Finally. Been. Published.

Yes, my new book with Paul Ehrlich, published by University of Chicago Press, is now available to purchase in book shops and online distributors around the world. The blog post today is a little explanatory synopsis of why we wrote the book and what it contains, but of course the real ‘meat’ is in the book. I hope you enjoy it.

In Australia, you can purchase the hard copy through Footprint Books, and the Kindle version at Amazon Australia. I also suggest that Australians might find the best deals through Booko. Electronic versions are also available through Kobo and Google Play. In the US you can order directly from University of Chicago Press, Amazon, Barnes & Noble, and many other book sellers. In the UK and Europe, the book is available from your country’s Amazon distributor. I imagine many chain and independent book sellers will be carrying the book by now, or will be soon.

My deepest thanks to all those who made it possible.

Our chance meeting in 2009 at Stanford University turned out to be auspicious, not least of which because of the publication this week of our co-authored book, Killing the Koala and Poisoning the Prairie. Australia, America and the Environment by University of Chicago Press. As a mid-career ecologist (Bradshaw) based at the University of Adelaide, it was indeed an honour to meet one of the most famous scientists (Ehrlich) in my field. With a list of books and hundreds of scientific papers under his belt, Ehrlich has been tackling major environmental issues since the 1960s. Ehrlich also has a long-time interest in Australia, having visited nearly every year during the last four decades and experienced more of the country than most Australians. Together we have observed firsthand the similarities and differences of Australia and the US, and the eyes we see through are trained as those of environmental scientists and evolutionary biologists.

So why write a book about the environmental tragedies currently unfolding in two completely different countries at opposite ends of the Earth? As it turns out, Australia and the US have much more in common environmentally than one might think, and not necessarily in a good way. Despite our vastly different floras and faunas, population densities, histories of human colonisation and soil productivities, there is an almost spooky similarity in the environmental and political problems both our countries are now experiencing. As such, we have a lot to learn about avoiding each other’s mistakes.

Ausmerica

Australia and the contiguous US are roughly equivalent in land area, both cultures are derived originally and principally from what is now the United Kingdom, and both are examples of super-consuming, super-wasting, wealthy, literate countries. Both countries also have environmental footprints that exceed most other countries on Earth, with some of the world’s highest per capita rates of greenhouse-gas emissions, water consumption, species extinctions and deforestation.  Read the rest of this entry »





To spare or to share, that is a muddled question

Unfortunately, it ain't this simple (from doi:10.1016/j.foodpol.2010.11.008)

Unfortunately, it ain’t this simple (from doi:10.1016/j.foodpol.2010.11.008)

Certain research trends in any field are inevitable, because once a seductive can of research-question worms is opened, it’s difficult to resist the temptation to start hooking in. Of course, I’m not against popular trends in research per se if they lead to a productive, empirical evaluation of the complexities involved, but it can sometimes result in a lot of wasted time. For example, in conservation ecology we’ve had to suffer 15 years of wasted effort on disproving neutral theory, we’ve bashed heads unnecessarily regarding the infamous SLOSS (‘Single Large Or Several Small’ reserves) debates of the 1970s and 1980s, and we’ve pilfered precious years arguing about whether density feedback actually exists (answer: it does).

The latest populist research trend in conservation seems to be the ‘land sparing versus land sharing’ debate, which, I (and others) argue, is largely an overly simplistic waste of time, money and intellectual advancement to the detriment of both biodiversity and human well-being.

Land sparing is generally used in reference to agricultural practices (although in theory, it could apply to any human endeavour where native vegetation cover is required to be removed or degraded, such as for electricity production) that are purposely made to be high-yielding so that they require the smallest amount of land. At the other extreme (and the ‘two extremes’ of a continuum concept is half the bloody problem here), land sharing requires a larger land footprint because it relies on lower-yielding, biodiversity-friendly (agricultural) practices. Proponents of land sparing argue that only by amalgamating patches of remnant native vegetation can we avoid massive fragmentation and the pursuant loss of biodiversity, whereas those pushing for land sparing argue that the matrix between the big undeveloped bits must be exploited in a more biodiversity-friendly way to allow species to persist.

As it turns out, they’re both right (but their single-minded, extremist positions are not). Read the rest of this entry »





How things have (not) changed

13 04 2015

The other night I had the pleasure of dining with the former Australian Democrats leader and senator, Dr John Coulter, at the home of Dr Paul Willis (Director of the Royal Institution of Australia). It was an enlightening evening.

While we discussed many things, the 84 year-old Dr Coulter showed me a rather amazing advert that he and several hundred other scientists, technologists and economists constructed to alert the leaders of Australia that it was heading down the wrong path. It was amazing for three reasons: (i) it was written in 1971, (ii) it was published in The Australian, and (iii) it could have, with a few modifications, been written for today’s Australia.

If you’re an Australian and have even a modicum of environmental understanding, you’ll know that The Australian is a Murdochian rag infamous for its war on science and reason. Even I have had a run-in with its outdated, consumerist and blinkered editorial board. You certainly wouldn’t find an article like Dr Coulter’s in today’s Australian.

More importantly, this 44 year-old article has a lot today that is still relevant. While the language is a little outdated (and sexist), the grammar could use a few updates, and there are some predictions that clearly never came true, it’s telling that scientists and others have been worrying about the same things for quite some time.

In reading the article (reproduced below), one could challenge the authors for being naïve about how society can survive and even prosper despite a declining ecological life-support system. As I once queried Paul Ehrlich about some of his particularly doomerist predictions from over 50 years ago, he politely pointed out that much of what he predicted did, in fact, come true. There are over 1 billion people today that are starving, and another billion or so that are malnourished; combined, this is greater than the entire world population when Paul was born.

So while we might have delayed the crises, we certainly haven’t averted them. Technology does potentially play a positive role, but it can also increase our short-term carrying capacity and buffer the system against shocks. We then tend to ignore the indirect causes of failures like wars, famines and political instability because we do not recognise the real drivers: resource scarcity and ecosystem malfunction.

Australia has yet to learn its lesson.

Australia’s perfect storm of negligence

17 03 2015

If, for the purposes of some sick and twisted thought experiment, you were to design policies that would ensure the long-term failure of a wealthy, developed nation, you wouldn’t have to look farther than Australia’s current recipe for future disaster. I’m not trying to be provocative, but the warning signs are too bold and flashy to ignore. Let’s just run through some of the main ones:

1. As the lambasted and thoroughly flawed 2015 Intergenerational Report clearly demonstrates, our current government has no idea about the future threats of climate change. Dragged kicking and screaming into only a symbolic recognition of some ‘distant and currently irrelevant problem’, the Abbott-oir and his intergenerational criminals are well known for killing the carbon-pricing scheme, dismantling the Department of Climate Change, pulling out of major international talks on climate-change mitigation and installing a half-arsed, ineffective policy that will do nothing to stem our emissions. Combine that with comments like “coal is good for humanity“, and it’s easy to see how our current leaders have little idea about the future mess they’re creating.

2. Not content just to kick the shit out of any meaningful climate action, our government has also turned its back on any renewable energy target, and facilitated the fossil-fuel barons to dig more coal out of the ground. While South Australia’s Royal Commission on the nuclear fuel cycle is a welcome candle in the climate change-mitigation darkness here, it is far from becoming a national priority any time soon.

3. As has been well documented, the Abbott-oir ship of fools has also done whatever it can to turn back decades of environmental protections in less than six months of taking office. Everything from opening up national parks for exploitation, failing to protect marine sanctuaries, limiting environmental checks to promoting logging in World Heritage Areas, there is little room for hope that our crumbling environmental system will improve at all in the near to long term.
