Knowledge gaps and narrative traps in Madagascar’s environmental history

July 1, 2025
Onilahy River, southwest Madagascar

Madagascar’s environmental past is more complex and regionally diverse than the tired narrative of a once-forested island devastated by people would have us believe. In a just-published opinion piece led by one of my academic heroines, Alison Richard, we unpack this oversimplified story, showing how diverse landscapes—from ancient grasslands to dynamic forest mosaics—shifted over millennia, shaped by both natural forces and human action. Yet traces of that older narrative linger stubbornly in scientific debates and conservation strategies. Escaping this narrative trap requires paying closer attention to the deep-time environmental record and to the heterogeneity of human histories across the island.

Global carbon markets or local residents: forest restoration for whom?

January 6, 2025

Seems like everybody is planting trees or restoring forestlands these days. The emphasis is often on carbon capture to attenuate climate change. But this emphasis on carbon offsets (and the money behind it) draws in powerful global actors and carbon market intermediaries. Meanwhile, the costs of forest restoration are all too often unjustly borne by less powerful, local people living in places where trees are planted or restored. How forest restoration efforts be governed so that benefits can accrue at all spatial scales, from global to local?

Power dynamics in trans-disciplinary research: bashing square pegs into round holes?

July 4, 2024

There is a lot to be said for research that builds on lessons from many academic disciplines and between scientists and practitioners.  But in such research one always has to negotiate power relations.  Whose vision dominates, who compromises?  Who gets more of the funding?  Which framework is used?

Why forest transitions aren’t always sustainable: nine pitfalls

May 22, 2024

Stopping and reversing deforestation is a foremost priority in much of the tropics. Numerous policies and programs try to stem forest clearance, encourage tree planting, and restore forest landscapes. The hope is to promote “forest transitions” similar to the historical turnaround in forest cover trajectories in wealthy temperate countries. Such efforts have become all the more urgent given the climate and biodiversity crises. Yet it is often assumed that more forests is better and more sustainable, without careful consideration of how and where it happens, who wins and who loses, and what kinds of forests. In a recent open access paper, we identify nine pitfalls to such assumptions. Hopefully this inspires researchers, policymakers, and leaders to promote more diverse transitions to sustainable forest use and management.

The nine pitfalls and their implications for research and policy. (Figure 2 from our paper in the journal Environmental Conservation).

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.

When invasion ecology looks at cities and urban areas

November 10, 2017

The historical roots of urban invasion studies across the rural–rural-wild spectrum. Fig. 1 in Salomon Cavin & Kull 2017. Kindly drawn by Lionel Cavin.

The study of invasive plants and animals has started to pay attention to cities.  In a paper just out, written by my colleague Joëlle Salomon Cavin and me, we document this ‘urban turn’ and ask what its implications are.  Specifically, our paper does a few things. We review how the ecological sciences in general have long had blinders as far as matters urban go, but also the existence of alternative paradigms – notably in 20th century European circles and in diverse ‘urban ecology’ traditions. Then, we look in more detail at how invasion biology has dealt with (or ignored) cities. In doing so, we Read the rest of this entry »


Using the ‘regime shift’ concept to analyse society-environment change

November 8, 2017

What happens when you take a concept developed to describe lacustrine ecology or fire regimes and apply it to complex social-ecological phenomena involving politics, economics, culture, and more?  What challenges occur when concepts are borrowed from systems ecology or complexity science and applied to situations with people, power, perceptions, contingencies, and feelings?

I’m excited to announce a brand-new paper that addresses exactly these questions (official link; authors preprint PDF).  Published in Geographical Research, the paper does four things: Read the rest of this entry »


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.

What are the environmental humanities?

March 10, 2017

Among the most potent recent academic buzzwords must figure “The Environmental Humanities”. This bandwagon is clearly attractive: an ever-growing bouquet of new journals, positions, institutes, books, and networks carries this label.[*]

In this blog, I’d like to propose an alternative definition for what the environmental humanities constitute, one that goes a little bit against the standard definition. In short, instead of emphasising meta-discipline, interdisciplinarity, and knowledge domains, my definition emphasises modes of knowledge creation and communication. Let me explain.

The environmental humanities emerged in particular out of history and literature departments (environmental history, eco-criticism), with a number of other contributors from across a diverse spectrum of academia (Nye et al. 2013). Well-known figures like Henry David Thoreau and Aldo Leopold are claimed as predecessors. Definitions of the environmental humanities, in my (perhaps naïve) reading, seem to coalesce around three points: Read the rest of this entry »
