Paying to stop degrading

28 07 2017

green baby bathwaterWe conservationists don’t get a lot of good news these days, and even when we do, I am reminded of the (slightly modified) expression: one step forward, but ten steps backward. It’s enough to lead to depression.

Still, we soldier on, and now there are more and more philosophically positive events and venues for ‘optimistic’ conservation stories. Indeed, some of them have even appeared here on (mainly from Claire Wordley‘s excellent string of posts from Conservation Evidence — see here, here, here, here), as well as the much-publicised Conservation Optimism Summit and its American version, Earth Optimism.

A decade or so ago, payment for ecosystem services was all the rage. The idea was simple — pay people to conserve forests and other intact habitats instead of cutting them down for timber or to grow food. However, as the years passed, these types of programmes — which were often funded (or intended to be funded) through carbon-sequestration schemes) — showed little capacity to prevent deforestation at a landscape scale. Many people have therefore binned the entire idea as a result. Read the rest of this entry »

Two new postdoctoral positions in ecological network & vegetation modelling announced

21 07 2017


With the official start of the new ARC Centre of Excellence for Australian Biodiversity and Heritage (CABAH) in July, I am pleased to announce two new CABAH-funded postdoctoral positions (a.k.a. Research Associates) in my global ecology lab at Flinders University in Adelaide (Flinders Modelling Node).

One of these positions is a little different, and represents something of an experiment. The Research Associate in Palaeo-Vegetation Modelling is being restricted to women candidates; in other words, we’re only accepting applications from women for this one. In a quest to improve the gender balance in my lab and in universities in general, this is a step in the right direction.

The project itself is not overly prescribed, but we would like something along the following lines of inquiry: Read the rest of this entry »

Journal ranks 2016

14 07 2017

Many books

Last year we wrote a bibliometric paper describing a new way to rank journals, which I contend is a fairer representation of relative citation-based rankings by combining existing ones (e.g., ISI, Google Scholar and Scopus) into a composite rank. So, here are the 2016 ranks for (i) 93 ecology, conservation and multidisciplinary journals, and a subset of (ii) 46 ecology journals, (iii) 21 conservation journals, just as I have done in previous years (201520142013, 2012, 20112010, 2009, 2008).

Human population growth, refugees & environmental degradation

7 07 2017

refugeesThe global human population is now over 7.5 billion, and increasing by about 90 million each year. This means that we are predicted to exceed 9 billion people by 2050, with no peak in site this century and a world population of up to 12 billion by 2100. These staggering numbers are the result of being within the exponential phase of population growth since last century, such that some 14% of all human beings that have ever lived on the planet are still alive today. That is taking into account about the past 200,000 years, or 10,000 generations.

Of course just like the Earth’s resources, human beings are not distributed equally around the globe, nor are the population trends consistent among regions or nations. In fact, developing nations are contributing to the bulk of the global annual increase (around 89 million per year), whereas developed nations are contributing a growth of only about 1 million each year. Another demonstration of the disparity in human population distributon is that about half of all human beings live in just seven countries (China, India, USA, Indonesia, Brazil, Pakistan, Nigeria, and Bangladesh), representing just one quarter of the world’s total land area.
