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,... |
