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.

Announcing new project on forest landscapes in Vietnam (with PhD post)

April 25, 2017

Forest in Vietnam can mean many things. There are the dense, dipterocarp rainforests that have divulged mammal species previously unknown to science, like the saola. There are also the vast plantations of exotic acacias growing wood for industry, as I detailed in a previous blog entry. And these forests have changed rapidly in the past few decades in step with the country’s economy and politics. The country is often seen to have undergone a “forest transition”, whereby a previous history of deforestation transitions to a new phase characterised by forest stability and indeed regrowth (albeit largely with exotic plantations).  In a new research-for-development project (see PhD job ad here), we intend to investigate the exact nature of the forest transition and its feedback into sustainable development for the heavily peopled rural landscapes of Vietnam.

Invasive species: interdisciplinarity, ecosystem (dis)services, and aesthetics

February 21, 2017

Announcing a series of new publications on “invasive species”, all from the Socio-ecology of Acacia project in which I participated (funded by SESYNC and two German research institutes). Here’s why they are interesting: Read the rest of this entry »


Share bike commute: only 62% success

July 6, 2016

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.

Manifest for an environmental geography (in France)

May 20, 2016

cover of Chartier, D & E Rodary, eds. 2016. Manifeste pour une géographie environnementale. Paris: Les Presses Sciences Po.

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”[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.

Living with invasive plants in the Anthropocene

January 6, 2016

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 »


Farmer livelihood practices and the forest transition in Africa

December 19, 2015

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.
