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.
Global climate change and food security are complex and closely intertwined challenges. A key requirement for dealing with them successfully is that agriculture becomes more eco-efficient. As researchers work toward this goal, they must always ask, “Efficiency for whom?” Finding answers to this question requires that research be conducted from a systems perspective in a broadly participatory manner involving complex collaborative arrangements.
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.
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
Las políticas de desarrollo rural han evolucionado considerablemente en América Latina. Durante los últimos 15 años, una de las principales áreas de énfasis ha sido el desarrollo de iniciativas que promuevan la formación de cadenas productivas en el sector agrícola en torno a unos productos estratégicos, los cuales generan economías rurales mucho más competitivas. En Colombia, el enfoque es novedoso, ya que se centra en el establecimiento de organizaciones de cadenas en el ámbito nacional y regional.
Este documento, refleja la experiencia del CIAT en sistematizar experiencias de la iniciativa Alianzas de Aprendizaje (donde confluían distintos actores del mundo de la investigación y el desarollo rural que creían en la idea de que compartir su conocimiento traería un mayor beneficio para ellos mismos y sus beneficiarios)
El presente documento busca evaluar y documentar los cambios organizacionales e institucionales generados en el marco de la Alianza de Aprendizaje y el impacto de estos cambios en el desarrollo socioeconómico de las familias rurales -población meta de los socios de la Alianza-, en algunos sitios seleccionados.
Farmers in Asia like to grow cassava because the crop will tolerate long dry periods and poor soils, and will produce reasonable yields with little inputs. Most farmers realize, however, that cassava production on slopes can cause severe erosion, while production without fertilizer inputs may lead to a decline in soil productivity. Research has shown that cassava yields can be maintained for many years with adequate application of fertilizers, and that there are various ways to reduce erosion.
