New forests, new forest people (video presentation)

February 2, 2021

I was recently invited to give a presentation at University College London’s “Human Ecology Research Group” seminar series, and was asked record it in advance. I thank HERG for the invitation and the very fruitful discussion! I’m pleased to share the presentation here.

Summary: Forest landscapes and forest lives are mutating rapidly in central Vietnam. Non-native acacia plantations have boomed, local people have refashioned their livelihoods around these trees, in a context of diverse state policies. What is ‘sustainability’ in the face of these dynamics? This presentation seeks to give an overview of the progress of the “FT Viet” R4D project. I start describing the empirical case, then address the sustainability question before finishing with some comments on interdisciplinarity.

Arbres voyageurs et plantes invasives dans les pays du Sud

October 17, 2016

FGSE Unil ouverture des cours 2016-2017 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 »


Do plants need passports?

August 7, 2012

The landscapes that characterize different places on the earth, and from which many people earn their livelihoods and their sense of place, and which support diverse flora and fauna, are often built with a mix of local and introduced plants.  Sometimes, introduced plants succeed so wildly in their new home that people come to see them as weeds or pests, crowding out crops or native species, changing soil conditions, altering fire regimes, or affecting the water table.  The field of invasion biology emerged over the past few decades seeking to document, understand, and stop such “alien invasions”.   But the fervour of this effort has at times crashed head-on with alternative worldviews.  One of South Africa’s top weeds, for example, is the Australian native silver wattle, also naturalized in France where it is celebrated for its winter flowers and as an ingredient for Chanel No. 5 and other perfumes [1][2].  Such conflicting outlooks were on stark display at a workshop I attended in October 2010 at Stellenbosch, South Africa, on Australian acacias as a global experiment in biogeography.

Picture 1: Do plants need passports? Who should control plant movements, and on what basis? Silver wattle (Acacia dealbata), native to Australia, invasive and assimilated as mimosa in the Côte d’Azur, France.

Picture 2: Do Australian acacias need passports? Australian passports specify “free passage without let or hindrance”…
