Considering the existing world population, set of environmental impacts, and predicted changes in dietary trends, one can expect that, in the coming decades, food security will remain high on the list of sustainability concerns. In relation to this challenge, Europe's Common Agricultural Policy (CAP) must address a diverse set of goals: (i) guarantee a stable and affordable food supply; (ii) preserve the socioeconomic stability of farmers by guaranteeing their economic viability; (iii) protect the environment by reducing pressures on agroecosystems; and (iv) improve food security by reducing import dependence. Policies related to these diverse goals are likely to generate adverse side-effects. A particularly uncomfortable concern is Europe's massive reliance on imported feed commodities. The European Union (EU) is unlikely to be capable of domestically producing currently imported agricultural commodities and a significant move to internalize imports would dramatically increase pressures on local ecosystems. Faced with that potential predicament, it is essential to have a robust information system capable of simultaneously addressing a variety of policy concerns. In response, this paper presents a novel accounting framework—Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM)—capable of generating an integrated set of indicators entangled across different scales and dimensions of analysis. Our versatile approach establishes a set of quantitative relations between: (i) the dietary intake of the society (desirability of the food supply); (ii) processes under human control (viability of the food system); (iii) processes outside of human control and associated with external biophysical limits determined by embedding ecosystems (feasibility of the food system); and (iv) the dependence on imported products (food security). The analysis of such relations can be tailored to the legitimate perceptions of different social actors affected by policies, anticipating potential conflicts and ...

The paper presents insights from carrying out a pan-EU sustainability assessment using Farm Accountancy Data Network (FADN) data (the old wine) with societal metabolism accounting (SMA) processes (the new bottles). The SMA was deployed as part of a transdisciplinary study with EU policy stakeholders of how EU policy may need to change to deliver sustainability commitments, particularly to the UN Sustainable Development Goals. The paper outlines the concepts underlying SMA and its specific implementation using the FADN data. A key focus was on the interactions between crop and livestock systems and how this determines imported feedstuffs requirements, with environmental and other footprints beyond the EU. Examples of agricultural production systems performance are presented in terms of financial/efficiency, resource use (particularly the water footprint) and quantifies potential pressures on the environment. Benefits and limitations of the FADN dataset and the SMA outputs are discussed, highlighting the challenges of linking quantified pressures with environmental impacts. The paper concludes that the complexity of agriculture's interactions with economy and society means there is great need for conceptual frameworks, such as SMA, that can take multiple, non-equivalent, perspectives and that can be deployed with policy stakeholders despite generating uncomfortable knowledge. ; This project was funded by the European Union's Horizon 2020 Research and Innovation Programme under grant agreement No. 689669.
