| The study compared the environmental impacts of different production systems (conventional, increased animal welfare label and organic) for beef, pork and chicken meat at the farm gate using model farms based on Swiss real farm data. Results showed that feeding and feed production had a high influence, particularly for monogastric animals. Organic farming had lower mineral resource use and ecotoxicity due to the ban of mineral fertilisers and pesticides but had a lower productivity per area, which influenced several impact categories such as eutrophication and land use negatively when expressed per kg live weight. Fundamentally, most of the decisive parameters for the environmental impacts of a production system turned out to be generally valid for both... |

| One of the primary challenges of our time is develop sustainable farming systems that can feed the world with minimal environmental impact. Some studies argue that organic farming systems are best because these have minimal impact on the environment and are positive for biodiversity. Others argue that no-tillage systems are better because such systems save energy and preserve soil structure and quality. A third group argues that conventional farming systems are best because yield per hectare is highest. However, so far, systematic comparisons of major arable production systems are rare and often it is difficult to compare the advantages and disadvantages of farming systems in a systematic way due to differences in soil/site characteristics and management.... |

| The environmental impacts of the conventional and organic farming systems practised in the DOC trial (organic-dynamic, organic and conventional farming) have been assessed by the SALCA life cycle assessment method. Both organic farming systems were more favourable for the environment in all investigated impacts per area unit. When analysed per product unit, clear advantages of organic farming were found for ecotoxicity and the use of mineral resources, while energy use and eutrophication were similar to conventional farming. Reducing fertilisation by 50% led to lower or equal environmental impacts for all systems, depending on the impact category and the functional unit. The analysis of single crops revealed large differences that are partly... |

| The economic efficiency of financial support of organic farming has been questioned by economists and policy makers. However, little empirical research has been done in order to evaluate the economic performance of these payments. Thus, the aim of this paper is to calculate the cost effectiveness of organic farming support in achieving environmental policy targets compared to other agri-environmental measures. The cost-effectiveness of agri-environmental measures can be understood as a function of policy uptake, environmental effects, and public expenditure. Taking the Swiss agricultural sector as an empirical case study, cost-effectiveness of organic farming support and other single agri environmental measures was calculated. For this purpose, the... |
