Approaches to assess the environmental impact of organic farming with particular regard to Denmark
Provedor de dados: 21
Autores: Hansen, Birgitte; Alrøe, Hugo Fjelsted; Kristensen, Erik Steen.
Ever increasing attention is being paid to the environmental impact of intensive agricultural practices, and in this context organic farming is gaining recognition as a relatively friendly production system. In general, the risk of harmful environmental effects is lower with organic than with conventional farming methods, though not necessarily so. This review examines organic farming in the light of European conditions, with special regard to recent research findings from Denmark. It specifies the environmental problems caused by modern farming practices and discusses appropriate indicators for assessing their impact.    A Driving Force-State-Response (DSR) framework is employed to organise and understand the processes and mechanisms that lie behind the...

Food safety in an organic perspective
Provedor de dados: 21
Autores: Kristensen, Erik Steen; Alrøe, Hugo Fjelsted; Hansen, Birgitte.
The holistic perspective of organic farming implies a broader conception of food safety that includes both product safety and agri-food system safety. The credibility of organic food can only be maintained if the organic agri-food system is developed in correspondence with the basic organic principles. In this way it will be possible to show the whole organic agri-food system as a safer alternative to conventional farming. Thereby trust will be supported in organic foods despite the sparse (and often unattainable) hard scientific evidence that organic food is healthier.

Grundvandsbeskyttelse ved økologisk jordbrug
Provedor de dados: 21
Autores: Hansen, Birgitte; Kristensen, Erik Steen.
Økologisk jordbrug udgør et samlet koncept, som både kombinerer stor dannelse af grundvand, pesticicforbud, mange positive miljøeffekter og merindtjening i landbrugserhvervet som følge af en merpris på produkterne. Økologisk jordbrug er derfor i mange tilfælde at foretrække frem for f.eks. skovrejsning eller pesticidfri dyrkning. Der er imidlertid problemer med at kunne forudsige kvælstofudvaskningen fra økologisk jordbrug især på grund af vanskeligheder med at kunne simulere udvaskningen fra forskellige typer græsmarker, som anvendes i stor udstrækning i økologisk jordbrug. Hvis der i grundvandsfølsomme områder stilles krav om pesticidfri dyrkning og at nitratkoncentrationen skal være under f.eks. 50 mg/l vurderes det, at disse krav vil kunne opfyldes...

Identifying the basic normative principles for organic farming
Provedor de dados: 21
Autores: Alrøe, Hugo Fjelsted; Kristensen, Erik Steen; Hansen, Birgitte.
What are the basic principles of 'how to act in an organic way'? In Denmark there has been a comprehensive discussion of this ethical question in connection with a major new organic research effort. Three related principles have crystallised in the discussion: the cyclical principle, the precautionary principle and the nearness principle. These principles have been used in an analysis of the acceptance of different technologies in organic farming and as a basis for making suggestions on future developments.

Assessment of food safety in organic farming
Provedor de dados: 21
Autores: Hansen, Birgitte; Alrøe, Hugo Fjelsted; Kristensen, Erik Steen; Wier, Mette.
Public concern about food safety in Europe has grown in response to the BSE scandal and problems with Salmonella and Campylobacter, etc. Such health and safety considerations are among the most important incentives for buying organic food, and have helped to promote rapid growth in the organic sector.     Against this background the present article reviews food safety from an organic perspective.  To our knowledge this has not been done previously. A novel definition is introduced which incorporates safety aspects of both the product and the agri-food-system. A Driving force-State-Impact-Response (DSIR) framework, that incorporates recent findings relating to organic products, is employed to analyse processes that control the safety of food. The safety of...
