The Human Genome Project is the attempt to sequence the complement of human DNA. Its ultimate purpose is to understand and control human genetics. The social and ethical concerns raised by this attempt have been much debated, especially fears concerning human genetic engineering and eugenics. An almost completely neglected aspect of the genome project's potential effects is its impact on world agriculture. The Human Genome Project will provide source information to transform commercially and therapeutically valuable segments of the human genetic code into agricultural products using the newly extant technologies of gene farming. This application of developing genomic technologies has at least two foreseeable effects: 1) Transforming global agricultural markets and ecologies, raising possibilities of novel forms of neocolonialism and the further destruction of genetic diversity; and 2) transforming world health and society through new modes of pharmaceutical production and the unregulated expansion of medical access to novel and traditional therapeutics.Mark Lesney received his Ph. D. in plant pathology and has worked as an assistant professor of biotechnology research at the University of Florida. He is currently affiliated with the program in History of Science at the University of Florida, where he is studying the emergence of biotechnology research. 相似文献

Technology transfer is a multi-level process of communication involving a variety of senders and receivers of ideas and materials. As a response to market failure, or as an effort to accelerate market-driven social change, technology transfer may combine public and private aparatus or rely solely on public institutional mechanisms to identify, develop, and deliver innovations and information. Technology transfer institutions include universities, government ministries, research institutes, and what may be termed the ‘project sector’. Four farm- and village-level change models are considered: traditional community development, adoption-diffusion, training and Visit Extension, and Farming Systems Research. The challenges to technology transfer efforts center on developing indigenous capacity to generate and adapt agricultural technology to local conditions. This is the primary objective of technology transfer in agriculture and the basis for advancing rural development. 相似文献

Sustainable feeding of the growing population in China without ecological destabilization is a grand challenge. In this populous country where agriculture is dominated by smallholder farming, developing innovative technology and translating scientific knowledge into action for smallholder farmers is a crucial step in addressing this challenge. Here, we present a novel approach for technology innovation and dissemination to achieve sustainable intensification in the fields of smallholder farmers. The Science and Technology Backyard(STB) is a hub in a rural area that links knowledge with practices to promote technology innovation and exchange. In this study, the framework and functions of STB are introduced, and the key implications for sustainable intensification across millions of smallholder farmers are explicitly stated:(i) develop innovative technology based on stated demands of farmers;(ii) disseminate technology by innovative social service models though combined top-down approaches with bottom-up measures to enable smallholders in rural areas. This paper provides a perspective on transformation of small-scale agriculture toward sustainable intensification in China and useful knowledge applicable to other developing countries. 相似文献

Researchers from Colorado State University, in collaboration with scientists from the United States Department of Agriculture (USDA), initiated a long-term multi-disciplinary study in precision agriculture in 1997. Site-specific management zones (SSMZ) were investigated as a means of improving nitrogen management in irrigated maize cropping systems. The objective was to develop precise nutrient management strategies for semi-arid irrigated cropping systems. This study was conducted in five fields in northeastern Colorado, USA. Two techniques for delineating management zones were developed and compared: SSMZ and yield-based management zones (YBMZ). Nitrogen uptake and grain yield differences among SSMZs were compared as were soil properties. Both management zone techniques were used to divide fields into smaller units that were different with regard to productivity potential (e.g., high zones had high productivity potential while low zones had low productivity potential). Economic analysis was also performed. Based on grain yield productivity, the SSMZs performed better than the YBMZ technique in most cases. Grain yield and N uptake between the low and high productivity management zones were statistically different for most site-years and N fertilizer rates (p < 0.05). Soil properties helped to explain the productivity potential of the management zones. The low SSMZ was markedly different from the high SSMZ based on bulk density, organic carbon, sand, silt, porosity and soil moisture. Net returns ranged from 188 to 679 USD ha?1. In two out of three site-years the variable yield goal strategy resulted in the largest net returns. In this study, the SSMZ approach delineates areas of different productivity accurately across the agricultural fields. The SSMZs are different with regard to soil properties as well as grain yield and N uptake. Site-specific management zones are an inexpensive and pragmatic approach to precise N management in irrigated maize. 相似文献

This paper offers a conceptualmodel for participatory research projects thataim to improve the sustainability ofagriculture and natural resource management.The purpose of the model is to provide asystematic framework that can guide the designof participatory research projects, theiranalysis, and the documentation of results. Inthe model, conceptual boundaries are drawnbetween research and development, developmentand extension and between extension andimplementation. Objectives, activities, andactors associated with each of these realmsneed to be carefully selected, monitored, andevaluated throughout the course of a projectusing well-designed indicators. The depth ofdisciplinary and methodological integration,and quality of participation needed to reachthe desired impact effectively and efficiently,however, needs to be determined on acase-by-case basis depending on the context andissues surrounding each particular project. 相似文献

Water quality in China is becoming a severe challenge for agriculture and food safety,and it might also impact health of population via agriculture and food. Thus,it is causing widespread concern. Based on extensive literatures review and data mining,current situation of water pollution in China and its effects on food safety were analyzed. The 2nd National Water Resource Survey in China show that the surface water all over the country was under slight pollution and about 60% of groundwater is polluted. Drinking water quality is basically guaranteed in urban area but it is worrisome in rural areas. In addition,China is the largest consumer of fertilizer and pestici de in the world and the amounts of application still show increasing trends. Fertilizers and pesticides are the most important sources of pollution,which affect human health as persistent organic pollutants and environmental endocrine disruptors. Eutrophication of surface water and nitrate pollution of groundwater are serious threats to drinking water safety. Sewage irrigation is becoming a pollution source to China's water and land because of lacking of effective regulations. Although,with the advance in technology and management level,control of nitrogen and phosphorus emissions and reducing water pollution is still a major challenge for China. 相似文献
