Genetically engineered (GE) foods apply new molecular technologies to Widely adopted in the United States, Brazil, and Argentina for the p corn, soybeans, and cotton, they are practically banned in Europe and tigh throughout the world. We have found that GE foods have significantly incr of corn, soybean, and cotton, and lowered their prices, thus improving food foods have already contributed to a reduction in the use of pesticides and
Brazilian agriculture is facing another expansion cycle to the Cerrado region, more specific in the Northeast. The first agriculture expansion cycle to the Midwest was in seventies encouraged and developed by Brazilian Government with farmers from southern and southeast Brazil, which were traditional small farmers with some experience, low budget and a remarkable determination. All of these efforts after 20 years resulted in an outstanding development of a part of the country with economy based on agribusiness (soybean, corn, cotton, livestock, poultry, swine, etc.).
This report shows some initial results about the research project entitled GlobalOrg, on a Brazilian case study, investigating the sustainability of tropical fruit organic farming in a global food chains perspective. It was performed an analysis about the production strategies of certified units of a familiar smalholders cooperative from Itápolis-SP-Brazil.
In the Amazon, slash and burn is the most common technique used by American-Indians, small farmers and even big ranches to transform forests into rural landscapes. The basis of food subsistence for diverse populations (rice, corn and bean), slash and burn is also a must for the plantation of cocoa, coffee, palms and pastures. The Amazonian rural landscape is currently dominated by pastures, occupying around 80 % of the deforested surface.
El objetivo del estudio fue evaluar el grado de sostenibilidad de agroecosistemas campesinos, a través de la aplicación del enfoque sistémico que permita una comprensión integrada de los impactos técnicos, ambientales, económicos y sociales, como base para apoyar el proceso de transición agroecológica. Para tanto se adoptaron marcos conceptuales empleadas por la Metodología MESMIS, a partir de un conjunto de atributos sistémicos para la evaluación de los agroecosistemas.
A group of researchers and industry writers have constructed a narrative of technological triumph for Bt cotton in India, based on an empirical record of superior performance compared to conventional seed. Counterclaims of Bt cotton failure are attributed to mutually reinforcing interactions among non-governmental organisations which avoid rigorous comparisons. However, researchers and the biotechnology industry are also engaged in a similar authentication loop for generating, validating, and publicising such facts.
This article rebuts the argument that shortcomings in Bt cotton studies and divergence between yield gains and extent of adoption of Bt hybrids make it impossible to conclusively say anything about the impact of genetically modified seeds. Further, it points out that there have been numerous studies that have controlled for selection and cultivation bias, and concluded that Bt cotton has had statistically significant positive yield effects.
ABSTRACT. In the last decades, a growing scholarship has outlined the crucial role of social networks as a source of resilience. However, with regard to the Global South, the role of social networks for the resilience of rural communities remains an under- researched and underconceptualized issue, because research remains scattered between different strands and has rarely been integrated from a resilience perspective.
In 2010 the Brazilian Government established a goal to reduce the emissions of greenhouse gases (GHG) by agriculture from 36.1 up to 38.9% in ten years (2010 -2020). To contribute for reaching part of this purpose in Tocantins State, Embrapa and other research and extension services partners have been conducting a project of technology transference on sustainable agricultural practices, including integrated crop-livestock-forestry (ICLF), since 2012.
In Pium, Tocantins state, Brazil, in 2012 Embrapa developed a technology transference project in partnership with the state?s rural extension service for the consolidation of low carbon emissions agriculture. The goal was to recover the degraded grasslands of the Trigueira farm (49°1'37.44"W and 10°24'58.84"S) with low cost using a crop-livestock system.
