Dairy farming significantly contributes to global greenhouse gas (GHG) emissions, particularly methane (CH4). This study evaluates the performance of Norwegian dairy farms and the socio-economic factors influencing emissions over 30 years (1991-2020). We assessed dairy farm performance by evaluating both efficiency and environmental impact, with a particular focus on reducing methane emissions. This is crucial for achieving sustainable and resource-efficient farming within a circular economy framework. Methane emissions were calculated using the Intergovernmental Panel on Climate Change (IPCC) Tier 2 methodology, incorporating country-specific data on dairy cattle diet and production. Utilizing a comprehensive panel dataset of 692 dairy farms, we employed a parametric model to analyze the intricate input-output relationships within dairy production. Our findings reveal an average eco-efficiency score of 0.95, suggesting a promising potential for a 5% reduction in resource use and CH4 emissions without compromising production levels. Socio-economic factors, such as land tenure, farm experience, and government subsidies, were found to exert a positive influence on both farm performance and GHG emissions. Conversely, higher debt-to-asset ratios were associated with lower performance. Our research underscores the necessity for policies that support improvements at the farm level, such as facilitating knowledge transfer among farmers and increasing access to subsidies for environmentally friendly technologies. Future research should delve into other environmental impacts, including nitrogen emissions and biodiversity, to establish a more comprehensive framework for sustainable agricultural practices. By identifying opportunities for reducing GHG emissions while maintaining productivity, this study offers valuable insights for policymakers and industry stakeholders seeking to enhance the sustainability of the dairy sector in Norway and beyond.

FoodsecURe: Food security through better sanitation: the case of urine recycling
Human urine contains essential plant nutrients. Hence, urine can serve as a “free” and locally available fertiliser. Successful, low-cost urine-diverting toilets (UDTs) that separately collect urine have been developed in Scandinavia and Europe and manufactured at large scale in Africa. A solution for stabilising urine into a solid fertiliser has also been developed. But why can't we recycle urine at scale? In Sweden UDTs are used in some cottages, and the Swedish University of Agricultural Science (SLU) has developed a method to stabilise and dry urine into a fertiliser product, urine-based fertiliser (UBF). FoodSecure aims to implement this technology at a medium scale in Ethiopia.

Agricultural mitigation measures and the value of water quality improvements
Agriculture is one of the main sources of water pollution in Norway, and an important contributor to GHG emissions.
