“…Desde un foco más general, ha habido publicaciones que analizaron más genéricamente el entramado sojero de la Argentina, Bolivia, Brasil, Paraguay y Uruguay -conjunto al que denominan irónicamente República Unida de la Soja-, y las implicancias socioambientales y en los cultivos que tiene este tipo de producción (Rocha, Nehring y Silva, 2022;Bravo et al, 2010), así como la confluencia productiva en el espacio trinacional fronterizo (Bolivia, Brasil y Perú, por un lado; y la Argentina, Brasil y Paraguay, por el otro), que demostraron la expansión en estos espacios transfronterizos de las cadenas productivas de agroganadería (Pires do Río y Nunez Coelho, 2020). Bravo et al (2010) describieron el avance de la soja, y específicamente de la transgénica, en el Cono Sur desde mediados de los años cincuenta, estudiando los modelos empresariales y de negocios que se desarrollaron en torno a este producto.…”

Este trabajo analiza la empresa Vicentin Paraguay Sociedad Anónima (VPSA) dentro de la constelación de actores económicos, productivos y gremiales de Paraguay. Si bien la filial fue fundada en el contexto de la estrategia de expansión regional del grupo económico argentino Vicentin SAIC, por la que se creaban firmas para aumentar la transacción intragrupo y evadir cargas impositivas, para operar de manera exitosa tuvo que relacionarse y negociar con un grupo de actores paraguayos que ejercen poder político y económico, de los cuales VPSA obtuvo protección y estabilidad. Desde la sociología económica, y siguiendo una metodología cualitativa (entrevistas en profundidad, análisis de documentos públicos y declaraciones empresariales, y análisis legislativo), respaldada en diversas fuentes estadísticas, este trabajo identifica la relevancia de las redes sociales y las relaciones personales en la estrategia de VPSA, aspecto marginado de los estudios centrados en Vicentin SAIC.

“…The green revolution model followed in Brazil has been based on a pattern of mechanization, chemical fertilization for soil dressing and correction, in addition to the use of pesticides to control pests and insects. In recent years, the country has stood out as one of the main import markets for pesticides, many of which are banned in their own countries of origin, especially by the European Union (Cabette et al, 2020;Rocha et al, 2022a;Rocha et al, 2022b). The discussion on control and/or flexibility in the use of pesticides in Brazil is associated with the context of the green revolution in the country (Glaeser, 2010;Paumgartten, 2020).…”

Introduction: The green revolution model that is followed in the Brazilian Cerrado is dependent on mechanization, chemical fertilization for soil dressing and correction, and the use of herbicides. Paraquat is a methyl viologen herbicide marketed as bipyridylium dichloride salts and used (in low doses) to combat weeds in their post-emergence stage. It is a non-selective pesticide that causes the peroxidation of the lipids that make up the cell membrane, and when it comes into contact with foliage, it results in the death of the plant.Methods: The effect of water molecules co-crystallized in Paraquat salt structures was analyzed in anhydrous, dihydrate, and trihydrate forms to understand those physicochemical properties in its redox activity. The frontier molecular orbitals were also carried out using DFT to obtain the chemical reactivity of the bipyridylium cation. Finally, the supramolecular arrangements were evaluated to analyze the physicochemical stability and acquire insights on superoxide anions.Results and discussion: The electronic structure indicated that the BP cation presents an acidic character due to its low ELUMO value, while the salt has a more basic character due to its high EHOMO value. For this reason, the BP ion is more susceptible to reduction during the weeds’ photosynthesis process. During the process of plant photosynthesis, PQ is reduced to form a stable radical cation. In the supramolecular arrangement, the presence of water molecules increases the number of strong H-bonds, while the weak/moderate H-bonds are stabilized. PQ’s toxic effects are observed in wildlife, domesticated animals, human populations, and ecosystems. The influence of PQ on the terrestrial environment is limited because of the soil adsorption capacity associated with good agricultural practices. The current use of good agricultural practices in the Cerrado seems not to prevent the environmental impacts of herbicides like PQ because it aims for the expansion and profitability of large-scale farming based on input-intensive practices instead of sustainable agriculture processes.

Farming cattle in the tropics: Transnational science and industrializing pastures in Brazil

Societal Impact StatementSociety is increasingly concerned over the environmental impact of diets. Much of this concern is over the environmentally destructive nature of meat production, especially beef and especially in the Amazon. This article aims to understand the production of beef in Brazil through the understudied perspective of forage grasses. In doing so, the article traces who was involved in the importation and improvement of forage grasses in Brazil, why they were involved, and what the consequences of their actions were. By centering forage grasses, we can better understand the potential consequences of seemingly unimportant plant breeding efforts.Summary Beef is viewed by many as one of the more environmentally destructive foods today. Whether it is deforestation in the Amazon or concentrated feedlots, the rancher and the cow have come to epitomize the dangers of a global industrial food system. This article looks at the industrialization of beef cattle from another angle, a bit closer to the ground. It looks at the role and circulation of plants and plant breeders in the expansion of beef cattle in the Brazilian tropics. The article draws on documents collected from the institutional archives of the Brazilian Agricultural Research Corporation, known by its Portuguese acronym Embrapa and the Rockefeller Archive Center. Additional archival documents were acquired by a personal contact. Embrapa was established in 1973, but its archives contain documents from Brazilian agricultural research agencies from as far back as 1952. Documents from the Rockefeller Archive Center include research bulletins and reports from Nelson Rockefeller's IBEC Research Institute (IRI), which conducted research on forage grasses from the 1950s until the 1970s. The article puts forth the argument that imported and improved forage grasses made large‐scale cattle ranching environmentally viable and economically profitable in Brazil. One type of grass in particular, Brachiaria, was central in propelling Brazil as the world's largest producer of beef and underpinning perhaps the most environmentally and socially destructive cattle ranching system in the world. Brachiaria was a key biological and technological input to further entrench longstanding structural inequalities of land ownership. One of the key conclusions of this article is that perspectives from the margins can be illustrative of how seemingly unimportant research (forage grass breeding) can have massive consequences as part of a broader socio‐environmental system.
