Recognition of community land rights: a tool against tropical deforestation

March 23, 2023

Wanting to preserve biodiversity in tropical forest areas without involving the local and indigenous communities that live there is neither fair nor effective, say ecologist Jacques Tassin and geographer Christian Kull. This was the tag line for our recent opinion piece published in the French newspaper Le Monde. Thanks so much to my friend and collaborator Jacques Tassin for involving me in this project. Below, I’ve made an English translation of the article, and also inserted some of the references that inspired us.

Explaining and using theories of ‘power’ in conservation

February 8, 2023

Power (to decide, implement, resist, inform, convince, …) is needed for good environmental management and nature conservation. It is often contested. Power is also sometimes hard to grasp – it can be held by certain people, by rules, by institutions, by ideas, or even by discourses. This new paper, fruit of a workshop organised by Ross Shackleton here at the University of Lausanne and fruitful exchanges between the co-authors, tries to clarify questions of power and proposes six guiding principles approaching power in conservation research and practice.

Different theories of power (Fig 1 from the paper)

What is “political ecology” these days?

May 31, 2022
This Figure describes three main poles in political ecology, distinguished by a focus on 'hatchet' versus 'seed' and whether
Three poles in political ecology, as proposed in Desvallées et al. (2022)

In a recent doctoral reading group here at the University of Lausanne, we discussed the 1987 text by Blaikie and Brookfield titled Land Degradation and Society, which is often cited as the foundational text for the field of political ecology. Comparing that groundbreaking work with current discussions under the political ecology label shows both continuities and new trends. Continuities include concern over environmental change and a ‘double posture’ of engaging with science on the issue at hand as well as a critical perspective with that science (for instance measuring soil degradation as well as asking what that concept means); concerns with the impacts of capitalism and colonialism; attention to property systems etc etc. Newer trends include the full-blown arrival of various approaches steeped in continental philosophy (poststructuralism, actor networks, assemblages, hegemony, bare life, governmentality….) and in diverse intersectional and decolonial postures. But where is the field now?

Voices from the forest – local people and conservation in Madagascar

December 21, 2021

Congratulations to the team from the “Forest4Climate&People” project at ESSA-Forêts (University of Antananarivo) and the School of Natural Sciences (Bangor University) for this fantastic short film. It is both beautifully done and really informative. Wonderful images as well as guitar picking by D’Gary. And most of all, it has a strong and clear message, contained in the subtitle, that advocates “putting local people at the heart of decisions about tropical forest’s contribution to tackling climate change”.

Tuna fishing in the Indian Ocean – marine political ecology (PhD Mialy Andriamahefazafy)

July 15, 2020

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.

Sheep and shepherds in the Swiss Alps (PhD Hélène Weber)

February 26, 2020

I’m proud to announce the successful public PhD defence of Hélène Weber, who has worked with me for five years as a doctoral assistant.  Hélène researched a practice operating in the spatial, cultural, and political margins of Swiss agriculture: sheep farming. She investigated the on-going transformation of sheep farming in Switzerland, pushed by eco-modernist policies, market institutions and demands, and also by the actors themselves and their practices and relationships (farmers, herders, sheep, grass, dogs…). Hélène’s intuition was that an ethnographic, practice-centred approach to her topic would give different and complementary insights.

Photo essay on forest change in central Vietnam

I’m happy to announce that the Swiss Programme for Research on Global Issues for Development (r4d) has published my photo essay regarding our work in the mountains of Thừa Thiên-Huế province in central Vietnam. You can see it here:

Navigating Forest Changes in Central Vietnam


Forest livelihood transformations: from wartime ‘A Shau valley’ to today’s A Lưới district

May 1, 2019

A few weeks ago I had the pleasure of joining PhD student Nguyen Thi Hai Van in her field sites in the upland A Lưới district of Thừa Thiên-Huế province, central Vietnam. She introduced me to her key informants, took me around the fields and woodlots, and translated as she conducted a number of focus group sessions. Of the many interesting ideas and observations that emerged, the overall theme was certainly one of the dramatic and rapid changes affecting the peoples’ livelihoods and landscapes.

Towards a “critical” invasion science

June 11, 2018

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 »
