Circular Agronomics (CA) provides a comprehensive synthesis of practical solutions to improve the current Carbon (C), Nitrogen (N) and Phosphorus (P) cycling in European agro-ecosystems and related up- and down-stream processes within the value-chain of food production. The proposed solutions would constitute a further step towards making agriculture an integral part of a circular economy by increasing resource efficiency while simultaneously addressing associated environmental challenges such as greenhouse gas and ammonia emissions as well as eutrophication of water bodies. Along 7 work packages and 6 case-studies, representing locations with different biogeographic conditions and environmental challenges typical for the European agricultural sector, the objective of CA is to contribute to a development towards sustainable, resilient and inclusive economies that are part of circular and zero-waste societies. The involved multi-actor and international consortium aims (i) To increase the understanding of C, N, P flows and the related potential to reduce environmental impacts at farm and regional level under different bio-geographical conditions; (ii) To close loops within cropland farming, from livestock to cropland farming and to increase the reuse of waste/wastewater from food-industry to improve soil fertility and to increase nutrient use efficiency; (iii) To highlight the performance of different prototypes of agro-ecological systems and increase sustainability of food production in the EU; and (iv) To contribute to the improvement of the European Agricultural Policies by providing evidence based, farmer led and consumer relevant recommendations for the agri-food chain. Cross-cutting social, economic and environmental evaluation ensure the overall sustainability of the investigated solution.

Nearly 50% of the European Union (EU) land area is agricultural. However, the ecosystem services (ESS) provided by these agro-ecosystems – including food, bioenergy, water, carbon storage and biodiversity – are threatened by processes such as land-use intensification and changing climate. European, national and regional policy makers must hence rethink and redesign rural policy to enhance the sustainability of agricultural landscapes while ensuring farmers’ livelihoods at the same time. However, the policy impact assessment models currently used by the European Commission (EC) ignore the complexity of farmers’ decision making, potentially leading to incorrect predictions of policy outcomes. Furthermore, existing models focus on narrow aspects of agricultural economics (e.g. income), ignoring policy impacts on rural natural, social and cultural assets. BESTMAP will develop a new modelling framework using insights from behavioural theory, linking existing economic modelling with individual-farm Agent-Based Models. Using these new modular and customizable tools BESTMAP will quantitatively model, map and monitor co-designed policy scenarios’ impacts on the environment, climate system, delivery of ESS, as well as socio-economic metrics (e.g. jobs). BESTMAP outputs will improve and contribute to existing tools used by the EC such as the Modular Applied GeNeral Equilibrium Tool (MAGNET) and Common Agricultural Policy Regionalised Impact model (CAPRI). Finally, BESTMAP will use a range of external communication and dissemination methods, including online policy dashboard, workshops and training, to help build capacity for EC staff and policy makers at EU institutions, national, regional and local decision makers and expert personnel, as well as other researchers.

In line with the Zero Pollution action plan and the Farm to Fork Strategy, Nutribudget will develop the prototype of a first-of-its-kind integrated nutrient management platform, called Nutriplatform, in various regions across Europe. The Nutriplatform will operate as a decision-support tool (DST) for farmers, advisors and regional authorities and before the end of the project this prototype (as a stand-alone or integrated in the existing EC promoted FaST tool for nutrient management) will be tested and used by at least 40.000 farmers across Europe. Firstly, the development of the Nutriplatform will be based on the algorithms of two advanced newly developed holistic Nutrimodels that quantify the impact of agronomic mitigation measures to optimize nutrient budget and flow across scales (from farm to Europe), across elements (C) and nutrients (N, P, K, S, Ca, Mg, Cu and Zn) and by looking at various agronomic and environmental targets. The measures will be derived from (I) existing knowledge, including input from relevant EU projects (e.g. the 4 on nutrient recycling from the call) and (II) new data from field experiments with innovative mitigation measures and combinations thereof that connect animal and crop production via agro-processing industries in 5 pilot regions (4 nutrient hotspot and 1 nutrient deficient area) in 4 different climate regions in Europe. Secondly, these measures will be linked to relevant monitoring indicators, called NutriKPIs, for agronomic performance in different farming systems, nutrient emissions and impact on biodiversity. All will be done in co-creation, according to a Nutri-actor approach, with a consortium of 17 partners from 10 countries that are all experts in their respective fields. Thereby, Nutribudget will contribute to systemically optimize nutrient management across different agricultural production systems and regions in the EU to reduce pollution due to the excessive use of nutrients and nutrient losses to the environment.

SYSTEMIC will reach a break-through to re-enter recovered nutrients from organic waste into the production cycle. Consequently, this will offer solutions for pressing environmental issues and to reduce the import of P as finite irreplaceable resource in mines. The SYSTEMIC project aims to shift the European Biomass treatment practice to the next level. Departing from existing business cases and a new ground-breaking large scale demonstration plant, the future of anaerobic digestion (AD) value chains will be investigated and demonstrated. The result will help existing and future AD-operators to maximise their performance: produce and sell more quality products, generate more energy and be independent on subsidies. By the market driven leadership, the SYSTEMIC-project will finally turn biomass waste into valuable products while reducing water pollution, greenhouse gas emission and creating quality jobs in rural areas. The planned demonstration plant will allow innovative combinations of modules to elaborate possible optimizations for increasing the production quantity and quality of new mineral products, and the integration of these products into a circular economy. Reflecting the experiences from the demonstration plant with a set of 4 mirror cases in different members states allow systemic innovation including end-user driven (a) specific technical development and (b) the cost efficient investigation of real world circular economy business cases and (c) operational, regulatory, institutional and contextual barriers to overcome. Using partial funding from the EC, the SYSTEMIC industry-driven consortium will validate for the first time the technical and economic viability of a fully integrated, multistep approach in an operational environment. The successful practical demonstration will put the European sector in a leading position to offer efficient mineral recovery technologies.
