Beyond the rice paddies, beyond the orchards of litchi, cloves, and coffee, beyond the rare patches of lemur inhabited natural forest, beyond the swidden fallows, a new landscape has appeared in lowland eastern Madagascar in the past half century. These ‘neo-Australian’ forests include four or five trees introduced from Australia that have, in many ways, become integral to regional lifeways: Read the rest of this entry »
The study of invasive plants and animals might be seen as the domain of biology and environmental managers. But in a recent piece I argue for a “critical” approach due to the deeply social nature of invasion landscapes, the power relations affecting the science of invasions, and the differential impacts of weed or pest control on lives and landscapes. By “critical” invasion science, I mean research that is informed by social theories, with a sensibility to questions of social justice and to the social construction of scientific knowledge. The piece investigates several aspects of invasion science ripe for critical analysis: the history of the science (to understand what the science is doing and why), the terminology and categories of analysis, and the highly contested social, political, and ethical context within which invasion management takes place. The piece conclude with four proposals for further work in critical invasion science and examples of the types of questions it might ask. Read the rest of this entry »
I’d like to introduce my current doctoral team, who are a great pleasure to work with. Their research interests have coalesced around the political ecology of environmental governance, specifically of forests, commodities, and rivers. In other words, who decides, who wins, who loses, and why, when decisions are made about trees, water, fish, cocoa, and sheep? What ideas are decisions based on, and how does the materiality of the object shape the outcomes? Here are some brief words on the team and their interests, grouped by three general themes: Read the rest of this entry »
The study of invasive plants and animals has started to pay attention to cities. In a paper just out, written by my colleague Joëlle Salomon Cavin and me, we document this ‘urban turn’ and ask what its implications are. Specifically, our paper does a few things. We review how the ecological sciences in general have long had blinders as far as matters urban go, but also the existence of alternative paradigms – notably in 20th century European circles and in diverse ‘urban ecology’ traditions. Then, we look in more detail at how invasion biology has dealt with (or ignored) cities. In doing so, we Read the rest of this entry »
The past week marked the launch of our new, Swiss government funded research project on the “forest transition” in Vietnam, which I’m leading in collaboration with colleagues Trần Nam Thắng and Ngô Trí Dũng of Huế University and Roland Cochard at Unil (see previous blog). The project aims to promote sustainable forest management and resilient rural livelihoods in the rapidly changing forest landscapes of this region.
The terrifying and sad images emerging from last Saturday’s fires in central Portugal struck me in their similarity to the 2009 Black Saturday fires around Melbourne where I used to live. But the similarity is more than the day of the week, the record-high numbers of fatalities, the images of charred cars trapped along the road, and the human tragedy. The other similarity is the vegetation: a fairly impressive portion of Portugal is covered by “neo-Australian” landscapes of introduced eucalyptus trees, as well as acacias and hakea.
A quick and dirty look at the extent of the fire in comparison shows clearly that the fires spread largely in eucalyptus forests:
Eucalyptus trees, as well as other elements of Australia’s vegetation, are of course highly fire adapted. Native Iberian cork oaks and pines are of course also no strangers to fire, but the question that has increasingly been raised in the press is to what extent eucalypts are to blame in the recent tragedy (in English, see articles for instance in Politico, LA Times, NYTimes).
