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 »


A political ecology of weeds

October 1, 2015

How do plants that move and spread across landscapes become branded as weeds and thereby objects of contention and control? In a chapter recently published in the International Handbook of Political Ecology, Priya Rangan and I outline a political ecology approach that builds on a Lefebvrian understanding of the production of space, identifying three scalar moments that make plants into ‘weeds’ in different spatial contexts and landscapes.

Field trip: indigenous perspectives on weeds in the Kimberley

September 25, 2013

The team of our current ARC-funded project on local knowledge and uses of environmental weeds recently assembled in Kununurra, far northwest Australia.  The project will compare local people’s views of “weeds” across four case studies in four countries around the Indian Ocean – India, South Africa, Madagascar, and Australia.  My Monash colleague Priya Rangan and I are collaborating with Charlie Shackleton (Rhodes University, South Africa) and Ramesh Kannan (ATREE, India), supported by Tom Bach (doctoral student on our previous ARC grant) and Pat Lowe (Kimberley-based author and environmentalist).

Living with, living without weeds: bridging theory and practice

March 9, 2013

A few weeks ago I attended a workshop by this name in Wollongong, organized by Lesley Head, Jenny Atchison, and Nick Gill. With keynote papers by Richard Hobbs, known for the ‘novel ecosystems‘ concept, and by Brendon Larson, known for his book Metaphors for Environmental Sustainability, and with presentations by participants as diverse as uniformed state Noxious Weeds Inspectors, indigenous rangers, government scientists, and historians of science, we kicked off a fantastic conversation on how weeds in the landscape are already a ‘new normal’. The threat of invasion is old news; the challenge of living with invasives is the new. In this respect, managers of environmental weeds could learn from those who have focused on cropfield or pasture weeds – they have been ‘living with’ weeds for a long time, and don’t see the world in such black and white terms.  For more information and comments, see this Blog by the workshop organisers.
