The technopolitics of agronomic knowledge and tropical(izing) vegetables in Brazil

The technopolitics of agronomic knowledge and tropical(izing) vegetables in Brazil

This article critically analyzes the social and political factors behind the advancement of technoscientific development in modern Brazilian agriculture. In the second half of the 20th century, Brazil underwent a rapid industrialization in the agricultural sector by more than doubling productivity in key global commodities and a widespread migration of people from rural to urban areas. Most observers point to the Brazilian Agricultural Research Corporation (Embrapa) as the technological engine that drove the industrialization of Brazilian agriculture. Existing approaches to analyze technoscientific development tend to overlook the role of the environment and individual scientists in enacting change. I argue that, especially in the case of agriculture, technoscientific development hinges on the extent to which the environment is disregarded or embraced by those who have the institutional support and capacity to innovate. To support my argument, I draw on two contrasting cases of crop development spearheaded by Embrapa scientists: the tropicalization of the carrot and participatory research on non-conventional vegetables. Through those two cases, the article demonstrates how the general and specific, the transnational and local, and the industrial and agroecological are all key contrasting factors for understanding technoscientific development in agriculture. This research is based on extensive interviews and participant observation at Embrapa’s vegetable research center near Brasilia, Brazil.

The history of crop science and the future of food

The history of crop science and the future of food

Historical memory is often short, and perhaps nowhere more so than in scientific research. As scientists chase new insights and novel tools, they are rarely rewarded for possessing deep knowledge of their disciplines’ past trajectories. Textbook sidebars spotlight singular individuals or celebrated experiments, and institutional accounts highlight founders and funders. Such highlights introduce a tiny—and unrepresentative—fraction of scientific work. Yet, the possibilities and pitfalls of today’s research are conditioned by the past.

The political economy of agroecological transitions: Key analytical dimensions

The political economy of agroecological transitions: Key analytical dimensions

There is a growing global interest in agroecology, yet agroecological transitions remain fraught with challenges. These include the need to reconfigure the productive and reproductive agrarian relations of unsustainable food systems and to rethink how we work with ecosystems. Using a political economy approach, we propose five key interrelated dimensions for analyzing agroecological transitions: (i) social metabolism; (ii) labor dynamics; (iii) markets and resources; (iv) social organization; and (iv) policies and politics. While these dimensions are often analyzed separately and to varying degrees, we argue that together they contribute to a comprehensive analysis of the political economy of agroecological transitions.
