Tany malalaka: settling new land in the western highlands of Madagascar

December 9, 2023

Like over a million (!) other viewers, I was captivated by the recent video “What’s inside this crater in Madagascar?” by Christophe Haubursin on Vox. Curiosity, satellite images, internet, a budget for a talented local filmmaker, and excellent production allow the team to explore why a village appears out of nothing fifteen years ago inside a remote broad, circular mountain in central Madagascar. Having spent days and days poring over historical air photos and maps of highland Madagascar for my own research, I palpably felt empathy for Haubursin’s landscape voyeurism. Then imagine my excitement as I realised I’ve been there myself, almost at the village site, on the southern summit of the mountain Ambohiby, in 1999, before it was built!

In this post, I’ll do two things: comment on some photos from my 1999 climb of Ambohiby, and give some leads for people looking to read further on the colonisation of empty lands in highland Madagascar, as I have been researching the settlement of new lands by Betsileo farmers since my masters thesis fieldwork in 1994.

Acacia tree farmers in central Vietnam

July 10, 2023

Colleagues from the FT Viet project have now published their top-notch research based on a set of rigorous in-depth surveys of tree farmers in Thừa Thiên-Huế province, central Vietnam. About a fifth of this province is now covered with tree plantations, mostly comprising the Australasian fast-growing tree Acacia magnum and Acacia magnum x Acacia auriculiformis hybrids. They interviewed 180 farmers across districts in the coastal plains, midland hills, and uplands, with half involved in Forest Stewardship Council groups that produce timber sawlogs under FSC certification standards, and half not involved (these tended to produce wood chips instead). The two published articles are an extremely rich and well-described source for understanding the development of acacia plantations over time, their relation to farmer assets and livelihoods, changes in land management, and farmer’s views on environmental challenges and future opportunities.

Fire, afforestation, and agrarian change in highland Madagascar (video)

November 8, 2021

I recorded a short video last summer for an interdisciplinary workshop that outlines in a brief way my work on highland Madagascar. You can watch it here on YouTube.

The video was made for a fantastic workshop on the grassy biomes of Madagascar held online last summer, bringing together archaeologists, diverse types of ecologists-biologists-botanists, palaeoecologists, geologists and more. Other videos are available here.


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.

Socio-ecological landscapes of Thừa Thiên-Huế province

September 19, 2017

Unrecognizable 20 years ago: Acacia plantations and new road in Nam Đông district, Thừa Thiên-Huế province.

The past week marked the launch of our new, Swiss government funded research project on the “forest transition” in Vietnam, which I’m leading in collaboration with colleagues Trần Nam Thắng and Ngô Trí Dũng of Huế University and Roland Cochard at Unil (see previous blog). The project aims to promote sustainable forest management and resilient rural livelihoods in the rapidly changing forest landscapes of this region.

Hervé Rakoto and the farmers of highland Madagascar

February 8, 2017

The tantsaha, or farmers, of highland Madagascar lost one of their moHerve in the fieldst empathetic interlocutors in late 2015: the geographer Hervé Rakoto Ramiarantsoa. In his books and articles, Hervé investigated the lives and landscapes of rural Imerina, Betsileo, and Tanala country from the farmer’s perspectives. His wonder and respect for the farmer’s techniques, their intricate reworkings of canals, soils, and paddy fields, was as strong as a farmer’s polished wood angady spade.

Farmer livelihood practices and the forest transition in Africa

December 19, 2015

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.

Rural development and landscape transformations in highland Madagascar

September 10, 2013

How did forty years of rural development, population growth, and conservation action transform the landscapes of highland Madagascar? My recently published [1, 2] analysis of a region-wide sample of air photos from circa 1950 and 1991 document several key trends: crop fields, settlements, and exotic trees are replacing open grassland, while irrigated rice is expanding at the expense of wetland and riparian vegetation.

Melting pots of biodiversity

March 20, 2013

What happens when you combine human labour, introduced plants, and particular societal histories and structures in a certain tropical landscape?  You end up with anthropogenic or cultural landscapes – the “matrix” in current ecological jargon – such as the domesticated forests1 of southeast Asia, the tree gardens of Caribbean or Pacific islands, the shambas of Africa, the rice terraces of Madagascar.  Despite their aesthetic and cultural attractions, these smallholder farming landscapes are directly or implicitly critiqued by many – for not being as productive as modern industrial agriculture, for trapping people in rural poverty, and for taking up space at the expense of natural habitats.  In two recent papers with French collaborators, I argue instead that such landscapes can be sustainable sources of useful products, can facilitate vibrant and resilient rural communities, and can be resilient contributors to the functioning of local and global biophysical systems.
