I’m very excited to announce that in January 2015 I will be taking up a position as Professeur ordinaire at the Université de Lausanne, or “Unil”, on the shores of Lake Geneva, in Switzerland. Read the rest of this entry »
Invasion biology has been a remarkably active branch of the life sciences in the past two decades. My itinerary first crossed this field when I noticed, at the time of my move to Melbourne, that the ‘precious’ mimosas (acacias, wattles) of the Madagascar highlands were called ‘green cancer’ in South Africa, and in both cases were introduced from Australia. It was quite surprising to discover that this shrubby tree, so appreciated by Malagasy farmers (as a resource) and environmental managers (as ‘regreening’ barren lands), was seen so negatively across the Mozambique Channel. This observation led to a research program that (1) opened a window for me to learn about and consider the field of invasion biology, and (2), serendipitously, to collaboration with ecologist Jacques Tassin at the French research institute Cirad. I comment on some of the recent fruits of both in this blog.
I recently returned from my 11th trip to Madagascar in 22 years. My main goal was to scope out potential field sites for an ARC-supported research project entitled “A weed by any other name? Comparing local knowledge and uses of environmental weeds around the Indian Ocean” (with collaborators Priya Rangan, Charlie Shackleton, and Nitin Rai). I took two week-long trips from the capital, first south to my old highland stomping grounds around Antsirabe and Ambositra, and second east to the rice bread-basket of Lake Alaotra, the rainforest escarpment at Andasibe and Beforona, and the coastal plains and hills around Vatomandry. It was also a good opportunity to renew personal and professional connections, including at the University of Antananarivo’s forestry school (ESSA-Forêts), where I was invited to give a presentation. What did I find?
I’ve finally received my copy of the new edited book Conservation and Environmental Management in Madagascar, edited by Ivan Scales of Cambridge University. This will be a fantastic resource for scholars of Madagascar new and old, as well as more broadly. It includes chapters on a full array of topics: on biodiversity, palaeoecology, and archaeology, on the measurement and causes of deforestation, on environmental politics, policies, programs, and projects, and on different economic development-and-conservation solutions, often (but not always) from a political ecology perspective, broadly construed.
Highlights for me in the book – which also has two of my own chapters – include: Read the rest of this entry »
If stated often enough, a fact becomes truth. That seems to be the case with the oft-repeated figure that “Madagascar has lost 90% of its original forest cover”. The problem, as Bill McConnell of Michigan State University and I point out in a letter just published in Science magazine, is that this fact cannot be proven.
Recently, several geography programs I am familiar with – notably my own at Monash – have been in the throes of administrative reshuffling and identity crises. In written submissions, hallway chats, and meeting room polemics we have all declared, at one point or another, that the strength of Geography is its interdisciplinarity, its crossing of bridges between the natural and the social, between science and arts. We have also declared that the integrity of the discipline depends on it staying together as one, even though a climate modeller will have different needs than an analyst of urban indigenous social movements.

There are three main types of fire in Fiji. Sugar cane farmers burn their fields to facilitate hand harvesting. Village farmers clear forest plots, fallow fields, and secondary vegetation for diverse crops using fire. And finally, the fires that cover the most ground are those set in the grasslands of the drier, lee-side of the islands. And of course there are occasionally fires that cause trouble – late last year I saw a major fire burning through the pine plantations in southeastern Viti Levu.
