New Tools for Sustainable Farming

Environmentalists are just as fond of talking about it as are politicians, economists or marketing experts – "sustainability" has become a buzzword. The problem is that the term sustainability can refer to many things and have manifold interpretations. Agricultural scientists at the Technische Universitaet Muenchen have shed light on the subject. Together with colleagues in theoretical and applied science they have managed to give the term "sustainability" a more definite meaning. They have helped to make this multi-faceted concept quantifiable – a benefit to farmers, food manufacturers and consumers alike. The research question was: How can the sustainability status of farms with available operating data be determined and systematically improved? The goal was very ambitious – to improve the environmental balance of agricultural enterprises without compromising their operating efficiency and social performance. In years of meticulous work to this end, the team of researchers developed indicators and models to analyze, assess and optimize the sustainability of agricultural enterprises. After all, sustainable farming really does benefit everybody: It conserves natural resources, saves energy, reduces the need for pesticides and fertilizers, and fosters a healthier environment, more competitive farms and safe foodstuffs. Thanks to their new indicator model, the TUM researchers are now able to describe agricultural enterprises as systems based on their material and energy flows...USNews
