| Input Output Accountingsystems (IOAs) can be used to identify farming practices which are not ‘environmentally neutral’ and thus unlikely to be sustainable in the long term. In an EU sponsored project, European countries were surveyed and over 50 farm level IOAs identified. The subjects covered by the IOAs included nutrients, pesticides, energy, soil/habitat, conservation, wastes (e.g.packagingandtyres)and other items such as veterinary products. Nearly half the IOAs covered more than one subject and nutrient budgets were the most commonly included(91% of the IOAs studied). Looking at the 30 single subject systems, most (26)were nutrients with only three pesticide and one energy based system. In total 50 systems covered nutrients. Overall, where specified,... |

| Of 241 questionnaires sent out to 20 countries 55 completed forms were returned. No information could be obtained about systems in Portugal or the USA. The subject of nutrients was covered by 91% of systems, pesticides 38%, energy 29% and other subjects including wastes 44%. Nearly half of the systems covered more than one subject, the most common single subject system was nutrients. The arable sector was covered most often by the systems (76%), with dairy (62%) and pig (56%) the most prominent of the livestock sectors. The respondents judged that 65% of systems were at least moderately effective in improving the ratio of inputs to outputs. The highest levels of ratio reduction tended to occur with systems which included the livestock sectors or... |
