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 »
Geographers 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.
In 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”. 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. 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.
I’m on the flight home reflecting on the ENTITLE “Undisciplined Environments” conference, a gathering of 500 (!) people, mostly academics, but also activists and artists, under the banner of political ecology. What is this ‘political ecology’ that brought so many people to Stockholm? Does it mean the same thing as when Land Degradation and Society was written some 30 years ago, a spirit of disciplinary crossing and plural epistemologies but rooted in a cross fertilization of cultural ecology and Marxist political economy? What I found was an open collective of intellectuals engaged in red-green issues of social justice and environment and keen to use social theory. Read the rest of this entry »
What 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.

What 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 »
In what situations do the practices of small-scale family farmers lead to increased tree cover, particularly on a continent better known for land degradation and deforestation? Research on the “forest transition”, a pattern where net deforestation is replaced by a net gain in forest cover, has so far avoided much mention of Africa. In contrast, it is historically documented in western Europe, eastern North America, east Asia, and seemingly underway in parts of Latin America and Southeast Asia. This research tends to focus on factors such as economic modernisation, rural abandonment, urbanisation, or even globalisation as driving forces of the forest transition. Two recent studies I contributed to focus instead on Africa – one in West Africa, one in Madagascar – and on transitions brought about by rural farmers. Read the rest of this entry »
