Synthesis of the principal environmental and human-health related standards applying to agriculture in the EU, Australia, Canada, New Zealand and the USA. The report provides one of the first comprehensive surveys of the main environmental and human health prob-lems related to agriculture in these countries. A broad range of problems is surveyed, including the quality of water, soil and air, bio-diversity and landscape, genetically modified organisms, animal welfare and human health. The policy measures in place to treat the measures are compared. Using this analysis, a preliminary assessment is made of the implications of differences in standards for the relative competitiveness of EU agriculture vis-à-vis the other four countries.
