Se evaluó la aceptación de una nueva tecnología de manejo integrado del cultivo de papayo en el ejido Miralejos, municipio de Soledad de Doblado, Veracruz, México. Se encuestaron 32 productores antes y después de asistir a eventos demostrativos en tres parcelas del ejido. El análisis multivariado de componentes principales mostró evidencia significativa que engloba la opinión de los encuestados respecto a los cambios de actitud positiva hacia la tecnología
Agroproductividad es una revista de divulgación científica y tecnológica, auspiciada por el Colegio de Postgraduados de forma mensual para entregar los resultados obtenidos por los investigadores en ciencias agrícolas y afines. En esta edición los artículos presentes son: 1) Cadenas de importancia socioeconómica para el
El presente trabajo ofrece un panorama global del mercado existente de los productos de origen animal, principalmente de carne y leche, con el propósito de obtener un panorama general de la producción caprina y valorar algunas perspectivas de la producción caprina en México y el mundo. Se enfatiza en los sistemas tradicionales de producción caprina y las perspectivas de desarrollo de la producción caprina a distintos niveles: local, regional, nacional e internacional
By late in the twentieth century, scientists had succeeded in manip- ulating organisms at the genetic level, mainly by gene transfer. The major impact of this technology has been seen in the spread of geneti- cally modified (GM) crops, which has occurred with little controversy in some areas and with fierce controversy elsewhere. GM crops raise a very wide range of questions, and I address three areas of particular interest for anthropology and its allied fields.
Precision farming enables agricultural management decisions to be tailored spatially and temporally. Site-specific sensing, sampling, and managing allow farmers to treat a field as a heterogeneous entity. Through targeted use of in- puts, precision farming reduces waste, thereby cutting both private variable costs and the environmental costs such as those of agrichemical residuals. At present, large farms in developed countries are the main adopters of pre- cision farming.
The pursuit of sustainability in particular places and sectors often unravels at the edges. Efforts to tackle environmental problems in one place shift them somewhere else or are overwhelmed by external changes in drivers. Gains in energy efficiency of appliances used in houses are offset by greater total numbers or compensating changes in patterns of use. Analytical perspectives and practical initiatives, which treat production and consumption jointly, are needed to complement experiences and efforts with sector-, place-, product- and consumer-oriented approaches.
With 20% of the world's population but just 7% of the arable land, China has invested heavily in crop biotechnology to increase agricultural productivity. We examine research on insect-resistant genetically engineered (IRGE) crops in China, including strategies to promote their sustainable use. IRGE cotton, rice, and corn lines have been developed and proven efficacious for controlling lepidopteran crop pests. Ecological impact studies have demonstrated conservation of natural enemies of crop pests and halo suppression of crop-pest populations on a local scale.
Agricultural biotechnology and, specifically, the development of genetically modified (GM) crops have been controversial for several reasons, including concerns that the technology poses potential negative environmental or health effects, that the technology would lead to the (further) corporatization of agriculture, and that it is simply unethical to manipulate life in the laboratory. GM crops have been part of the agricultural landscape for more than 15 years and have now been adopted on more than 170 million hectares (ha) in both developed countries (48%) and developing countries (52%).
This article presents lessons from the rich adoption literature for the nascent research on adaptation. Individuals' adoption choices are affected by profit and risk considerations and by credit and biophysical constraints. New technologies spread gradually, reflecting heterogeneity among potential adopters, processes of learning and technological improvement, and policies and institutions. Adaptation is the response of economic agents and societies to major shocks. We distinguish between reactive and proactive adaptation.
A nutrition-sensitive food system is one that goes beyond staple grain productivity and places emphasis on the consumption of micronutrient-rich nonstaples through a variety of market and nonmarket interventions. A nutrition-sensitive approach not only considers policies related to macrolevel availability and access to nutritious food, but it also focuses on household- and individual-level determinants of improved nutrition. In addition to agriculture, intrahousehold equity, behavior change, food safety, and access to clean water and sanitation are integral components of the food system.
