This research project addresses primary production in Norwegian agriculture in a value chain perspective reaching from soil and plant resources (WP1) to economics of farming systems (WP2) and the farmers socio-cultural involvement (WP3). The overall goal of the project is to create a sound knowledge basis for increased production, productivity and sustainability in domestic food production. The challenge of synthesizing research findings from different disciplines towards the overall goal is acknowledged and addressed by a team dedicated to develop interdisciplinary approaches (WP4). Conventional and novel approaches of disseminating the knowledge to farmers and decision makers are sought (WP5). The natural science part of the proposal emphasizes robust plant material and soil cultivation strategies suitable for future climate and soil conditions. Nutrient use efficiency is proposed as a common metrics for evaluating environmental effects. The project strongly draws on the coordinated interaction of the main national players in agronomic, economic and societal research: Norwegian University of Life Sciences (NMBU), NIBIO - Norwegian Institute of Bioeconomy Research, Centre for Rural Research (CRR), Norwegian Agricultural Extension Service (NLR) and the international cooperation contributed by each partner. The central hypothesis of the project is that Norwegian food production can be increased sustainably by identifying the main drivers and constraints behind agronomic practice in the central production systems and by suggesting potential changes to them. As such, agricultural practice and its aggregate effects on food production and environment on a national scale will be at the center of the proposed project.
