Workshop on Mennonite colony expansion

10/21/2025

0 Comments

 
As part of the project "Land for the faithful", the LENDEV lab held a workshop to discuss dynamics of expansion of Mennonite colonies in Latin America, with a focus on recent colonies in Argentina and Peru. The lab's Ana Laura Llanes and Yann le Polain, as well as collaborator and former Mennonitische Post editor Kennert Giesbrecht, presented their fieldwork in these new colonies. Ben Nobbs-Thiessen, the Chair of Mennonite Studies at the University of Winnipeg, presented his ongoing work with Mennonite return migrants in Canada, and Hannah Zhao (McGill) told us about her ongoing work analyzing how colonies are connected across distances. Our colleagues Oliver Coomes (McGill) and Christian Abizaid (University of Toronto) provided important insights and reflections, particularly on the Peruvian context. Over two days, we shared insights and charted outlines for what will hopefully be a few different research and non-academic outputs to come in the next year or two. Stay tuned!

On September 9, Olivia successfully defended her PhD thesis, titled "Beyond the deforestation front: Capturing the dynamics of early commodity frontier expansion". Congratulations Dr. del Giorgio! Olivia has been part of the LENDEV lab since 2018, when she started her Master's - we'll miss her dearly but are also excited for her to embark on new academic adventures. Some of Olivia's graduate work is already published: check it out under the Publications tab. You can also follow her next steps on her website or on her LinkedIn page.

New paper: Dream Brokers

In a new paper published in World Development, LENDEV PI Yann le Polain and collaborator Angela Kronenburg García explore the discursive dimensions of agricultural frontiers. In this study, we argue that frontier actors, in response to increasing pressures to be environmentally and socially responsible, deploy narratives that seek to resolve moral tensions around their activities in an attempt both to lessen exposure to criticism and to appease their own moral insecurities. Check it out here to learn more!

New paper: revealing land control dynamics

6/6/2025

Putting land claiming on the map reveals that the footprint of agricultural frontiers extends far into seemingly ‘intact’ forests.

In ‘Revealing land control dynamics in emerging agricultural frontiers', LENDEV lab's Olivia del Giorgio and colleagues develop a novel remote sensing and GIS approach to map and analyze the land claiming activity that takes place before large-scale deforestation for agriculture.

Applying the approach to the Gran Chaco, the authors not only found land claiming concentrated around active deforestation fronts. They show that claims fragment areas that, based on land-use change indicators alone, would be considered largely ‘untouched’ by agricultural activity.

In exposing the spread of land claiming across the Chaco their analysis shows intense land pressure on smallholders there: where land claims were highest, homesteads disappeared most—both in deforested zones and in remote forested areas.

Beyond being an application useful going forward for the Chaco, the methodology can be used to detect land claiming indicators across contexts. It therefore opens opportunities for monitoring the early stages of commodity frontiers across tropical and sub-tropical forests globally.

New paper: "who defends us?"

2/28/2025

In a new article in Journal of Peasant Studies, Yann discusses how Criollo smallholders have been dealing with an upsurge in large-scale land deals in the Paraguayan Chaco over the last few decades. The upshot: they are doing all they can, but in the face of immense power imbalances, that is often still not enough.

Paraguay is experiencing tremendous pressure on land, with rates of conversion to agriculture among the highest in the world. In the Pilcomayo River basin, in the borderlands of Paraguay with Argentina and Bolivia, small-scale Criollo livestock herders are being squeezed out of their traditional livelihoods by outside investors.

Faced with constant pressure on land from outside actors, Criollo smallholders are responding in a variety of ways, including some contestation and resistance but also forms of everyday cooperation, intensification of production, livelihood diversification, and relocation.

These responses are shaping the Chaco landscapes even where the land has not yet been converted to large-scale agriculture by investors. People used to rely on an extensive, forest-based livestock herding system for a living. Today, those who are not driven out of livestock herding altogether are forced to fundamentally change their production systems to adapt to an increasingly scarce land base.

It is late to alter course, as most of the land in the Paraguayan Chaco has already been appropriated and converted by large-scale actors, but securing land tenure for those families that are still on the land but do not have titles and providing legal support to those currently facing investor claims on their land should be the absolute priority for any entity seeking to support the region’s Criollo population.

The LENDEV lab was in Oaxaca, Mexico, for the Global Land Programme's 5th Open Science Meeting, an opportunity to present ongoing work and meet many interesting folks working on land use change around the world! And of course a chance to see the sights and try some local food and Mezcal!

paper: Agricultural expansion & water access

7/22/2024

New paper by former LENDEV lab member Patrice Matthews! In "Troubled Waters", Patrice shows how agricultural expansion in the Gran Chaco is leading to the marginalization of smallholders through reduced water access. Many smallholders in the Chaco critically depend on access to surface water, such as rivers, for themselves and their livestock. In the Pilcomayo basin, Patrice shows that the average distance to surface water for smallholder living in homesteads in the forest has increased a lot between 2000-2018, mostly due to agricultural expansion.

Paper: Frontier constellations in the Pilcomayo

In a new paper published in the Geographical Review, Yann explores the land-use history of the Pilcomayo River basin in the Paraguayan Chaco over the last century. Mobilizing the concept of "land-use regimes", he shows that the region has one through a series of distinct regimes with different logics, functions, and actors over its history. This leads to a discussion of the notion of regimes as a heuristic to discuss long-term land-use change. Check it out here!

Lab members Marie-Claude and Olivia, and lab PI Yann, presented their research at the 2024 Conference of Latin American Geography in San Juan, Puerto Rico, from May 22 to 26! They talked about capturing land control dynamics in early commodity frontiers (Olivia), about spillovers in forest carbon projects (Marie-Claude), and about smallholder strategies in the face of large-scale land acquisitions in the Gran Chaco.

Another field season in the pilcomayo

5/18/2024

0 Comments

 

Yann conducted another field season in the Pilcomayo River area in the Paraguayan Chaco in April/May. He first disseminated a booklet summarizing the history of the region, adapted from a paper about to be published - a promise he had made on earlier visits. He also continued inquiring about land-use dynamics, particularly the question of land-use intensification through pastures, and the moral economy of land. Fortunately, this time, the temperature was much more bearable, although rains made transportation difficult at times - the roads in the Pilcomayo turn to a very slippery mud as soon as it rains!
