With pride and pleasure I’d like to announce the successful doctorate of Mialy Andriamahefazafy, which she defended publicly on July 13. Mialy’s previous work with a marine conservation organisation in coastal Madagascar showed her that local fishers were complaining about big boats fishing offshore, while in the inland capital, government officials were keen on the revenue they could gain through access agreements with foreign tuna fleets. This inspiration led to her thesis work, in which investigated the socio-material matrix through which fishing occurs. She narrowed in on three main topics: how diverse actors ‘access’ the fish, how these actors ‘narrate’ their concerns over overfishing, and whether there is any sense in approaching this issue by appealing to a sense of ‘regional identity’. Mialy undertook fieldwork in three countries (Madagascar, Seychelles, and Mauritius), interviewing more than 223 individuals including small-scale fishers, industrial boat captains and sailors, government officials, cannery workers, retailers and more. Mialy also observed landings of tuna in ports both big and small, and practiced event ethnography by joining delegations to attend two international negotiations.

July 15, 2020Trees threaten grasslands in Madagascar more than fire
June 10, 2020Malagasy grasslands are often ignored, or worse, deplored. Biological research concentrates in the forests, many still shrinking despite conservation efforts. Yet research by plant ecologist Cédrique Solofondranohatra adds another layer of argument to the case that Malagasy grasslands have an ancient history and are important reservoirs of biodiversity themselves. Despite this, recent tree-planting efforts for climate change mitigation (of the ‘trillion trees‘ mode) often seem to take the easy path formed by a century of habit: planting exotic pines, acacias, and eucalypts in the grasslands, perceived as open, available, fire-damaged, and worthless. A much more laudable goal would be to restore trees to areas recently deforested.

Middle-range theories of land system change
September 14, 2018New paper in Global Environmental Change, under the amazing leadership of Patrick Meyfroidt, bringing together and surveying a wide family of theories of land use and land cover change.
Socio-ecological landscapes of Thừa Thiên-Huế province
September 19, 2017
Unrecognizable 20 years ago: Acacia plantations and new road in Nam Đông district, Thừa Thiên-Huế province.
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.
What are the environmental humanities?
March 10, 2017Among the most potent recent academic buzzwords must figure “The Environmental Humanities”. This bandwagon is clearly attractive: an ever-growing bouquet of new journals, positions, institutes, books, and networks carries this label.[*]
In this blog, I’d like to propose an alternative definition for what the environmental humanities constitute, one that goes a little bit against the standard definition. In short, instead of emphasising meta-discipline, interdisciplinarity, and knowledge domains, my definition emphasises modes of knowledge creation and communication. Let me explain.
The environmental humanities emerged in particular out of history and literature departments (environmental history, eco-criticism), with a number of other contributors from across a diverse spectrum of academia (Nye et al. 2013). Well-known figures like Henry David Thoreau and Aldo Leopold are claimed as predecessors. Definitions of the environmental humanities, in my (perhaps naïve) reading, seem to coalesce around three points: Read the rest of this entry »
Arbres voyageurs et plantes invasives dans les pays du Sud
October 17, 2016 Last month I gave the ceremonial first lecture of the academic year for our Faculty. The video is now online (see below). The presentation dips into a number of research projects I’ve contributed to in recent years in order to make a number of observations about the relationship between plants and people, notably with iconic ‘natural’ plants and problematic ‘invasive’ weeds. These observations include: Read the rest of this entry »
Share bike commute: only 62% success
July 6, 2016Geographers have long investigated commuting and transportation. While that isn’t my academic speciality, every commuter in the world probably has some comments and reflections on the “geographies of mobility” (to use current jargon). Here are my reflections on the city of Lausanne’s shared-bike program, initially sponsored by the two universities EPFL and UNIL.
Manifest for an environmental geography (in France)
May 20, 2016In September 2010, fifteen prominent senior French geographers, under the auspices of the Société de Géographie, held a one-day colloquium entitled Le ciel ne va pas nous tomber sur la tête (The sky will not fall on our heads). The participants critiqued the “prevailing obfuscation, radical environmentalism, de-growth, denial of science, and faith in humanity”[1]. While many geographers can sympathise with critiques of simplified or overly catastrophic environmental narratives, as well as with critiques of bad science, this book went much further. It verged on climate change denial and was underlain by the assumption that we need no changes to our lifestyles.[2] In direct response, two younger geographers named Denis Chartier and Estienne Rodary organized a conference entitled Géographie, Écologie, Politique: un climat de changement at the Université d’Orléans in September 2012 (see my blog entry at the time). Participants in Orléans expressed frustration with what they saw as the dominant school, the old guard. This conference also led to an edited volume, titled Manifeste pour une géographie environnementale, finally published a few months ago – the reason for this blog entry.
Political ecology and the Anthropocene
January 22, 2016What does the Anthropocene mean for subsistence farmers Lele or Rakoto? At first glance, nothing. It is, after all, just a fashionable term amongst the intelligentsia; the latest jargon to adorn project proposals to do more of the same. But on second thought, for these already marginal farmers, the Anthropocene might concretely mean less rains, stronger cyclones, new weeds: new stresses, challenges, and perhaps opportunities.

Living with invasive plants in the Anthropocene
January 6, 2016What does it mean to live with bioinvasions? Low-wage labourers donning chemical suits and goggles to spray herbicides in tropical heat? Exurban homeowners cutting back an invasive vine near their back porch, but letting it run wild at the other side of the property? State environmental managers making difficult choices about what weeds to spend money on? In a recent collective paper inspired by the Wollongong Weeds Workshop (Head et al. 2015, see below), we seek to draw attention to the practical, lived side of managing weeds.

The paper is organised around five themes that arise from managers’ reflections on their work. It identifies tensions between the ideals arising out of invasion biology, resulting regulatory and policy frameworks, and practical on-the-ground experience. Read the rest of this entry »
