Abstract

Switzerland aims to further reduce nitrogen and phosphorus emissions from agriculture. We explore the potential of three types of food system interventions. National farm gate budget calculations are complemented with additional indicators for efficiency, sufficiency, and circularity in nutrient management. Calculations also include the part of the global food system that produces agricultural products imported to Switzerland. Our results suggest that the potential to reduce nitrogen and phosphorus surplus through a combination of strategies exceeds the anticipated effect of currently prioritized measures. Our work also highlights how the additional indicators and extended system boundaries broaden the assessment and reveal aspects that would be concealed if relying solely on national farm gate budget calculations within Switzerland. Based on a refinement of our preliminary assumptions and estimations, future work could identify the crop and animal production systems that offer most leverage, as well as help define priority strategies and measures.

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
