Adoption of Transgenic Crops by Smallholder Farmers in Entre Rios, Argentina AgEcon
Paredes, Cecilia; Martin, Marshall A..
This is a study of the adoption of transgenic crops by 120 smallholder farmers interviewed in July 2005 in the communities of San Jose de Feliciano and La Paz in the Entre Rios Province of Argentina. Logistic regression results indicate that access to a planter is essential for smallholders to adopt Bt corn, while adopters of Roundup Ready™ soybeans have larger farms, access to credit, availability of all essential machinery, more years of schooling, and are primarily located in the La Paz community.
Tipo: Conference Paper or Presentation Palavras-chave: Transgenic crops; Technology adoption; Bt corn; Roundup Ready™ soybeans; Biotechnology; Argentina; Smallholders; Farm Management; Research and Development/Tech Change/Emerging Technologies.

An update on genetically modified crops Ciencia e Investigación Agraria
Schwember,Andrés R.
A. R. Schwember. 2008. An update on genetically modified crops. Cien. Inv. Agr. 35(3):231-250. Genetically modified (GM) crops were introduced in the mid 1990s and two principal transgenic technologies currently domínate the market, herbicide-tolerant (HT) crops and insect-resistant crops (Bacillus thuringiensis (Bt) crops). HT crops have simplified weed management practices, reduced crop production costs, and have had positive effects on the environment. However, there are concerns about the potential development of weeds resistant to glyphosate, the main herbicide employed with HT crops. A second major worry associated with the use of HT crops is the potential introgression of genes from GM crops into wild relatives (i.e. gene flow) and its potential...

Biotech--Who Wins? Economic Benefits and Costs of Biotechnology Innovations in Agriculture AgEcon
Moschini, GianCarlo.
The conceptual model necessary for an assessment of biotechnology's economic benefits and costs is outlined, emphasizing the need to account for the proprietary nature of biotechnology innovations. The model is illustrated with an application to Roundup Ready soybeans. The estimated value of this innovation is sizeable, with consumers and innovators claiming the largest shares of net benefits. Also, disparities in intellectual property rights protection across countries affect the distribution of benefits. Consumer resistance toward GMOs and the issue of labelling and market segregation complicate the economic evaluation of biotechnology innovations; a number of related regulation and public policy issues are discussed. Emerging output-trait GMOs are...

PIRES, C. S. S.; SILVEIRA, F. A.; CARDOSO, C. F.; SUJII, E. R.; PAULA, D. P.; FONTES, E. M. G.; SILVA, J. P. da; RODRIGUES, S. M. M.; ANDOW, D. A..
The objective of this work was to list potential candidate bee species for environmental risk assessment (ERA) of genetically modified (GM) cotton and to identify the most suited bee species for this task, according to their abundance and geographical distribution. Field inventories of bee on cotton flowers were performed in the states of Bahia and Mato Grosso, and in Distrito Federal, Brazil. During a 344 hour sampling, 3,470 bees from 74 species were recovered, at eight sites. Apis mellifera dominated the bee assemblages at all sites. Sampling at two sites that received no insecticide application was sufficient to identify the three most common and geographically widespread wild species: Paratrigona lineata , Melissoptila cnecomola and Trigona spinipes ,...
