International Communication plays an important role in our society. Agenda setting theory emerges from communications studies and focuses on mass media influence on setting political agenda.The theory explains the correlation between the rate at which media cover a story and the extent that people think that this story is important. The media has become a strong barrier of communication between families and the outside world.  相似文献

Agri-environment schemes were introduced in the mid-1980s. Their primary objectives have developed from initially aiming to hold back intensification towards stimulating environmental enhancement. The introduction of Entry Level Stewardship (ELS) in England represents a third stage in seeking to extend the coverage of schemes across the majority of agricultural land. This aims to influence land use along the whole of the intensive margin. The ELS offers a wide range of options for which farmers are awarded points. Selection of options equivalent to 30 points per ha in lowland areas entitles farmers to a payment of £30 per ha. By September 2007, 4.4 million ha had been entered into the scheme, equivalent to 47% of the agricultural area. From amongst the options on offer, 34% of points were for boundary options, 20% for intensive grass options, 16% for management plans and 13% for options taking arable land out of production. The choice of options varies across the country with a higher proportion of the agricultural area entered in the East. Entry into the scheme is associated with total agricultural area, cereals farming, larger farms, a lower proportion of area in Environmentally Sensitive Area and Countryside Stewardship schemes and grazing livestock numbers. While the ELS has introduced a large number of new entrants into agri-environment schemes, the extent of the environmental impact is uncertain. Given the large number of options available, it is likely that farmers will have chosen options that involve relatively little change and incur limited cost. At the same time, it would be surprising if the environmental gains were of the types most valued within local areas. The ELS approach implies that public goods provided from agricultural land should be paid for irrespective of what would have happened in the absence of the scheme. While this may be a fairer approach, it may also undermine the idea of land stewardship and imply that payments will continue to be required in the long term in order to sustain provision. The ELS does establish a framework within which incentives could be targeted to deliver specific benefits within particular contexts and suggestions are made as to how policy might be developed for this.  相似文献

The introduction of farmer participatory approaches over the past decades has to some extent improved the relevance and uptake of research results. While R&D prioritization increasingly involves more stakeholders, including the private sector, policymakers and civil society, building ecological literacy among all stakeholders is urgent, especially for sustainable agricultural development. A case study of an emerging fruit innovation system in Guinea, West Africa, highlights the challenges of supply- and demand-driven approaches to R&D prioritization. Shallow ecological knowledge and a blind faith in ‘modern’ technologies by scientists and farmers alike distort prioritization. Locally available, appropriate technologies are dismissed in favour of high technologies that are inaccessible to most smallholder growers. Strengthening the ecological literacy of all stakeholders may help to overcome this bias. On the other hand, building socio-technological literacy would allow innovation intermediaries, who typically act as brokers between the demand- and supply-side of technologies, to better understand the social and institutional contexts of technologies and how these affect potential uptake by poor farmers. Member centres of the Consultative Group on International Agricultural Research (CGIAR) could use the notion of ecological and socio-technological literacy to better understand supply and demand of technology and to work more effectively with their partners towards pro-poor and sustainable agricultural development.  相似文献

Abstract

This paper aims to investigate changes in the structure of the Spanish quality beef industry in response to the significant decline in beef consumption happened over the last few decades. The role of product differentiation, mechanisms and factors involved in it, are specially studied. We use focus groups and a survey to examine the outlook for the organization of the beef industry, and trends in the development of product differentiation mechanisms and vertical co-ordination strategies.

Results reveal the existence of a restructuring process that is being implemented in two ways: Protected Geographical Indications (PGI) and Quality Certified Brands (QCB). Each strategy forms its own entry barriers: the origin of calves in the case of PGI and farm size in QCB; they are therefore complementary rather than competitive.  相似文献
