| Agriculture has manifold impacts on the environment and plays an important role in the environmental impacts of food chains. Previous studies have shown that organic farming can reduce these environmental impacts. But also within organic farms there is a high variability in their impacts on the environment. In our case study with five organic dairy farms, the farm with the highest energy demand used over 2.5 times more energy than the farm with the lowest energy demand. This indicates that further optimisations are possible. Therefore, the farmer is an important factor. The efficient use of his own resources together with an adept combination of different branches can contribute to the ecological optimisation of his farm. But for every farm and... |

| 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... |
