Relating life cycle assessment indicators to gross value added for Dutch dairy farms

摘要: Sustainable dairy production requires farms that are economically viable, environmentally sound and socially acceptable. A low environmental impact of milk is not necessarily associated with an viable farm. To gain insight into a possible “trade-off” between economic sustainability, the relation indicators was quantified, farm characteristics influence this were identified. Economic quantified for 119 specialized in 2005, based on data from Dutch Farm Accountancy Data Network (FADN). used were: gross value added expressed per kg fat-and-protein-corrected (FPCM) or unit labour, i.e. labour productivity.
