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.Read the rest of this entry »
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 »
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. Read the rest of this entry »
The baobab, that iconic, majestic, and grotesquely massive roots-in-the-sky tree, teaches us something surprising about “nature”. It demonstrates that what appears to be “natural” has been – for millennia and millennia – also fundamentally “social”, for people have been important dispersal agents of these trees. Researchers like Chris Duvall and Jean-Michel Leong Pock Tsy have shown this for the African baobabs.[1,2] Our recently completed research project, led by Priya Rangan, demonstrates this in multiple ways around the Indian Ocean. Baobabs are such useful and remarkable trees , it is hardly difficult to imagine people not picking up the hard but pleasantly light and fuzzy fruit pods and walking with them.
One part of our project looked at the single species of baobabs found in Australia: Adansonia gregorii, called boab. It grows in the Kimberley region in the northwestern part of the continent. In a study just published in PLoS ONE , we combine evidence from baobab genetics  and Australian Aboriginal languages to show that humans have been the primary agents of baobab dispersal. In particular, we reveal their crucial role in dispersing baobabs inland from now-submerged areas of northwest Australia during the dramatic sea-level rises at the end of the last glaciation. (See also this article in The Conversation as well as Priya’s blog about the study)
A further question is how the baobabs arrived in Australia in the first place. Oceanic dispersal via seed pods floating in currents, several million years ago, remains the most plausible explanation, as our collaborator David Baum has shown . Yet, another one of our baobab collaborators (and veritable Renaissance man) Jack Pettigrew advances an interesting speculative argument about a possible human role in transporting the baobabs, building on evidence from rock art in the Kimberley and in Read the rest of this entry »
What role did slaves from Africa and Madagascar play in transporting, spreading, and cultivating new plants in the sugar colonies of Mauritius and Reunion? What can plant names teach us about the lives and landscapes of marginalized people in the past? Read the rest of this entry »
