For the agriculture sector as a whole, FAPRI-Ireland finds that there would be a reduction in output value but this would be offset by a reduction in input costs brought about by lower animal numbers and more extensive production. There would also be environmental benefits to full decoupling with the reduction in livestock numbers bringing about a substantial drop in greenhouse gas emissions from the agriculture sector to approximately 14% below 1990 levels. In conclusion, the FAPRI-Ireland results showed that full decoupling would result in aggregate farm income being higher than would be the case if there were no policy change or if partial decoupling were implemented.
