The Agri-Environment Footprint Index (AFI) has been developed as a generic methodology to assess changes in the overall environmental impacts from agriculture at the farm level and to assist in the evaluation of European agri-environmental schemes (AES). The methodology is based on multi-criteria analysis (MCA) and involves stakeholder participation to provide a locally customised evaluation based on weighted environmental indicators. The methodology was subjected to a feasibility assessment in a series of case studies across the EU. The AFI approach was able to measure significant differences in environmental status between farms that participated in an AES and non-participants. Wider environmental concerns, beyond the scheme objectives, were also considered in some case studies and the benefits for identification of unintentional (and often beneficial) impacts of AESs are presented. The participatory approach to AES evaluation proved efficient in different environments and administrative contexts. The approach proved to be appropriate for environmental evaluation of complex agri-environment systems and can complement any evaluation conducted under the Common Monitoring and Evaluation Framework. The applicability of the AFI in routine monitoring of AES impacts and in providing feedback to improve policy design is discussed.  相似文献

This article is based on a specific situation and competence analysis research project. The objective of the project is to point out possible action areas for improvements and potential competence areas; areas that should be integrated in the company's future strategic work. In the long term, the objective is to develop specific tools that can support a company's decision processes when in and/or outsourcing. The specific tools form the basis for the development of a conceptual framework that may facilitate the work with and the understanding of strategic in and outsourcing.During recent years new theories on SCM, outsourcing, supplier cooperation, etc. have emerged. Each theory has its own specific basis seeking to give solutions to problems concerning how to use and cooperate with suppliers. All theories, however, seek to solve a well-known problem within economic theory. Thus, the issue on division of labour and specialization is well known (Foretag i netwark, Stockholm, Studieforbundet for Naringsliv och Sammhallet, 1982; Joint Venture: theoretische und empirische analyse unter besonderer berücksichtigung der chemischen industrie der schweiz. Verlag Rugger, Germany, 1989). From an economic point of view it is a question of reaching the situation with the lowest production and transaction costs (Handbook of Industrial Organization. Amsterdam, 1989, pp. 135).  相似文献

Previous research has shown consumers to be highly sceptical towards genetic modification in food production. So far, however, little research has tried to explain how consumers form attitudes and make decisions with regard to genetically modified foods. The paper presents the results of a survey which was carried out in Denmark, Germany, Italy, and the United Kingdom to investigate the formation of consumer attitudes towards genetic modification in food production and of purchase decisions with regard to genetically modified yoghurt and beer. Altogether, 2031 consumers were interviewed in the four countries.Results show that attitude formation and decision-making are more comparable among Danish, German, and British consumers than with Italian consumers. Italian consumers turned out to be significantly less negative towards genetic modification in foods than particularly Danish and German consumers. Across countries, the attitude towards genetic modification in food production was deeply embedded in more general attitudes held by the consumers, in particular attitude towards nature and attitude towards technology. These general attitudes were found to influence perceived risks and benefits of the technology. Purchase decisions with regard to the two product examples were almost exclusively determined by attitudes towards purchasing the products. These were, in turn, significantly influenced by the overall attitude towards genetic modification in food production through their effects on beliefs held by consumers regarding the quality and trustworthiness of the products.The results suggest that attitudes towards genetically modified foods are quite strong, despite their lack of basis in actual product experience. Likewise, the strong relation of product-specific attitudes to the attitude towards using genetic modification in food production suggests that at present consumers reject the technology overall rather than evaluate products on a case-by-case basis. This situation may, however, be changed by a possible increased availability of genetically modified food products on the consumer market.  相似文献

It is remarkable that despite wide-ranging, in-depth studies over many years, almost no conservation agriculture (CA) studies consider gender and gender relations as a potential explanatory factor for (low) adoption rates. This is important because CA demands new ways of working with the farm system. Implementation will inevitably involve a reallocation of men's and women's resources as well as having an impact upon their ability to realize their gender interests. With respect to intra-household decision-making and the distribution of benefits, CA interventions have implications for labour requirements and labour allocation, investment decisions with respect to mechanization and herbicide use, crop choice, and residue management. CA practice may impact upon the ability of households to source a wide variety of crops, wild plants, and insects and small animals for household nutrition. Gender biases in extension service design can sideline women. This paper examines the limited research to date on the interactions between CA interventions and gender in East and Southern Africa, and, based on the gaps observed, sets out a research agenda. It argues that attention to gender in CA is particularly timely given the increasing interest in CA as a means of adapting to climate change.  相似文献

Few studies have to date explained consumer attitudes and purchase decisions with regard to genetically engineered food products. However, the increased marketing of genetically engineered food products and the considerable concern that consumers seem to express with regard to the technology call for the development of a theoretical basis for research into these issues. The aim of this article is to present three models which the authors have developed to explain consumer attitudes, buying behaviour, and attitude change with regard to genetically engineered food products.All three models build on established consumer behaviour theory and on existing and comparable research in the field. Consumer attitudes toward genetic engineering in food products are explained in an attitude model that builds on Fishbein's multiattribute attitude model but deviates from Fishbein's model in a number of ways. Consumer buying behaviour with regard to specific genetically engineered food products is explained in a behavioural intention model which uses Ajzen's Theory of planned Behavior as its point of departure. How consumers' attitudes towards genetically engineered food products are affected by various information strategies, finally, is explained in an attitude change model which integrates aspects of the Elaboration Likelihood Model and Social Judgment Theory. The model specifically takes into account the impact of source credibility and various informational factors, such as persuasive content of the information provided, on attitudes.  相似文献

This paper applies a convention theory (CT) approach to the analysis of labour management systems in African large‐scale farming. The reconstruction of previous analyses of high‐value crop production on large‐scale farms in Africa in terms of CT suggests that, since 1980–95, labour management has moved from a ‘domestic’ to a ‘market’ system. However, data collected by the authors from a sample of 11 large‐scale rose farms in Kenya in 2011 (covering around 20% of national output) points to the adoption of systems that, in CT terms, combine ‘industrial’ and ‘civic’ elements. The paper concludes by suggesting a series of hypotheses that might explain this trend.  相似文献

The paper sets up a four-stage enforcement model of fish quotas. The purpose of the paper is to show how the level of enforcement set by the authorities affects the way fishermen form coalitions. We show that a high level of control effort yields less co-operation among fishermen, while in the case of low control effort, coalitions are somewhat self-enforcing. The paper further discusses how the optimal enforcement level changes when the coalition formation among authorities changes: centralised, partly centralised and decentralised authorities. We show that decentralised authorities set a lower level of control effort compared to the centralised authorities. The theoretical results are illustrated by simulations of the Baltic Sea cod fishery.The authors acknowledge valuable comments and suggestions from Frank Jensen and Niels Vestergaard.  相似文献
