Examining the Role of Collective Action in an Informal Seed System: A Case Study from the Central Valleys of Oaxaca, Mexico
Lone B. Badstue,Mauricio R. Bellon,Julien Berthaud,Xochitl Juarez,Irma Manuel Rosas,A. M. Solano,Alejandro Ramírez +6 more
TL;DR: In this paper, the authors explore social arrangements associated with seed transactions among small-scale maize farmers in the Central Valleys of Oaxaca, Mexico, where no formal seed supply system exists.
Journal ArticleDOI
Participatory landrace selection for on-farm conservation: an example from the central valleys of Oaxaca México
Mauricio R. Bellon,Julien Berthaud,Julien Berthaud,Melinda Smale,José Alfonso Aguirre,Suketoshi Taba,Flavio Aragon,Jaime Diaz,Humberto Castro +8 more
TL;DR: A method to identify a subset of landraces for further conservation efforts from a larger collection representing the diversity found in the Central Valleys of Oaxaca, Mexico, satisfies two criteria.
Journal ArticleDOI
The Dynamics of Farmers’ Maize Seed Supply Practices in the Central Valleys of Oaxaca, Mexico
Lone B. Badstue,Mauricio R. Bellon,Mauricio R. Bellon,Julien Berthaud,Julien Berthaud,Alejandro Ramírez,Dagoberto Flores,Xochitl Juarez +7 more
TL;DR: In this paper, the organizing principles that underlie and help shape farmers' seed supply practices in the Central Valleys of Oaxaca were discussed, and the implications of these practices for maize genetic diversity and the introduction of improved varieties.
Journal ArticleDOI
Transgenic Maize and the Evolution of Landrace Diversity in Mexico. The Importance of Farmers' Behavior
TL;DR: The discovery of transgenic products in maize landraces planted by small-scale Mexican farmers raised questions about how the commercial introduction of transgenetically modified maize varieties might affect the environment.
Journal ArticleDOI
Collective action for the conservation of on-farm genetic diversity in a center of crop diversity: An assessment of the role of traditional farmers' networks
Lone B. Badstue,Mauricio R. Bellon,Julien Berthaud,Alejandro Ramírez,Dagoberto Flores,Xochitl Juarez,Fabiola Ramirez +6 more
TL;DR: In this article, the authors explored the role of collective action among small-scale farmers in managing and maintaining genetic resources in a center of crop diversity and found that most transactions are bilateral and while the most common transaction is the sale and purchase of seed, this is not done for profit but out of a sense of moral obligation.
