We generally ignore the big issues

11 08 2014

I’ve had a good week at Stanford University with Paul Ehrlich where we’ve been putting the final touches1 on our book. It’s been taking a while to put together, but we’re both pretty happy with the result, which should be published by The University of Chicago Press within the first quarter of 2015.

It has indeed been a pleasure and a privilege to work with one of the greatest thinkers of our age, and let me tell you that at 82, he’s still a force with which to be reckoned. While I won’t divulge much of our discussions here given they’ll appear soon-ish in the book, I did want to raise one subject that I think we all need to think about a little more.

The issue is what we, as ecologists (I’m including conservation scientists here), choose to study and contemplate in our professional life.

I’m just as guilty as most of the rest of you, but I argue that our discipline is caught in a rut of irrelevancy on the grander scale. We spend a lot of time refining the basics of what we essentially already know pretty well. While there will be an eternity of processes to understand, species to describe, and relationships to measure, can our discipline really afford to avoid the biggest issues while biodiversity (and our society included) are flushed down the drain?

Energy policy – substance wins over style

4 02 2013

happy nuclearThere’s a gradual, but rising tide of rational, enviro-progressive scientists out there who are committed to solving some of the world’s biggest problems. Many of these problems involve touchy subjects, including ways to reduce poverty while improving or maintaining high standards of living elsewhere, the means for ‘sustainable’ electricity generation, and how to limit the human population’s over-consumption and over-production.

Inevitably, however, many well-intentioned, but grossly misinformed environmentalists (‘enviro-conservatives’?) object to technical solutions based on emotional or ideological grounds alone. As self-professed enviro-progressives (but also scientists who base decisions on evidence, logic and balancing trade-offs as part of our everyday work), we hope to reduce this backlash by providing the data and analyses needed to make the best and most coherent decisions about our future.

On 14 September 2012, Japan’s government announced a nuclear-free policy to phase out its nuclear power generation by 2040. Of course, electricity demand would have to be supplied by both renewable energy and fossil fuels to respond the public unwillingness for nuclear power.

But is this most environmentally sound, safest and economically rational aim? In a new paper we’ve just had published in the peer-reviewed journal Energy Policy, we set out to test Japan’s intentions the best way we know – using empirical data and robust scenario modelling.

Before the March 2011 earthquake and tsunami, Japan produced 25% of its total electricity consumption from nuclear power, 63% from fossil fuels (mostly coal and liquefied natural gas), and 10% from renewables (including hydro). Originally, the Japanese government had planned to increase nuclear power up to 45% of supply, and include new renewables builds, to combine to make major cuts in greenhouse gas emissions by 2030 and meet or exceed their Kyoto targets. However, the original plan could reduce emissions by the energy sector from 1122 Mt CO2e in 2010 to < 720 Mt CO2e by 2030 (< 70% of 1990 emission levels). Read the rest of this entry »





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 »
