Periodic Reporting for period 2 - Circular Agronomics (CIRCULAR AGRONOMICS - Efficient Carbon, Nitrogen and Phosphorus cycling in the European Agri-food System and related up- and down-stream processes to mitigate emissions)
Reporting period: 2020-03-01 to 2021-08-31
The potential impacts of CA comprise: Increased NUE along the EU Agri-food chain and improved overall sustainability; Increased innovation capacity of the farming systems; Reduced GHG and NH3 emissions; Protected and enhanced soil C stocks; Improved ground- and surface-water quality; Integrated scientific support for relevant EU policies; Strengthened transdisciplinary research for long-lasting implementation of results; CA will contribute to major EU policies; CA will generate social impact in direct and indirect manner by developing non-technical measures such as policy actions towards more sufficiency in agriculture, food consumption and waste management and towards a more sustainable and low-emission by closing C, N and P loop as much as possible; CA will develop affordable technical solutions which fit within the current structures of European agriculture, minimising the economic pressure on producers within the European agricultural sector so that food production costs remain stable.
The expected results are: an increase of the agronomic efficiency in terms of nutrient usage by 20 % compared to nowadays in conventional farming, summing up to a total potential in avoided emission of approx. 2 Mt/yr of N and 0.2 Mt/yr of P. The Life Cycle Assessment will assess sustainability with regard to environmental and emissions impacts across media (soil, water air) as well as for process optimization strategies and different aspects will be linked with governance in the policy impact assessment. As mid-term vision until 2030, an annual reduction of approx. 10-15 % of direct GHG emissions in agriculture in EU-28 is achievable. Out of this reduction 75 % will come from reduce N2O loss to the atmosphere and 25 % by reduced CH4 losses via measures in livestock farming. Approx. 7 Mt CO2-Eq/yr will be reduced via CA recovery approaches for N and P fertilizers. Related NH3 emissions and SO2 emissions to air causing terrestrial acidification can be reduced in similar magnitudes. NH3 emissions reductions can be achieved by choice of N-fertilizers and pH-Management of soils. For areas with low C stocks in soil a realistic target is to increase it by 10 % until 2030. A Reduction of NO3 emissions to receiving waters by 50 % in regions with high N surplus and by 10-15 % in European average. CA will produce a clear policy brief which will highlight to policy makers the barriers and bottlenecks which impede the greater take up system change along the food chain towards a more circular economy (CE). Exploitation will be maximized through CA’s dissemination plan which will encourage knowledge exchange with targeted stakeholders and through CA’s policy recommendations, ensuring that policy makers create the correct framework so that farmers, food-industry and retailers can establish and implement a practical and affordable circular economy within their sector.
