Emerging technologies in favour of sustainable agriculture

European agricultural systems are going through a modernisation process involving radical structural changes. To tackle these important challenges, technology foresight has been employed as a systematic, participatory, intelligence gathering exercise focusing on future R&D investments in sustainable agricultural systems and green technologies. Because reliable data on emerging technology are scarce, any assessment has to be based to a large extent on qualitative methods and on an operational conception of sustainability using priority indicators. The paper describes the Danish Green Technological Foresight on Environmental Friendly Agriculture (GTFEFA). It treats this as a case study and examines the way in which a group of interested parties arrived at recommendations on the application of a number of emerging agriculture-related technologies. Two questions are then addressed: Can technological foresight simultaneously: (1) systematically describe and evaluate the consequences of employing emerging technologies in order to choose between alternatives, and (2) prioritise investments in emerging technologies so as to favour innovation. The discussion here is intended to help meet the challenge of operationalising the term 'sustainability', so that environmental friendly agricultural technology can be assessed against priority indicators. Finally, it is suggested that, provided that clear criteria for assessing the sustainability of emerging technologies are identified and made explicit, technology foresight offers a space for dialogue and exploration in contested territory.
