Current agricultural practices in Europe are increasingly aggravating societal and environmental safety concerns. This creates social and regulatory pressures on farmers, which can lead to declining material and social status of farmers, farmer discontent, and anti-regulation protests. These tensions are rooted in conflicting value systems for agricultural development, which can range from productivist pathways (i.e. valuing production above all else) to increasing multifunctionality pathways (i.e. valuing agriculture for its contribution to multiple economic, environmental and societal needs). It is largely unknown to what degree individual farms and agricultural landscapes are transitioning towards increasing productivism or multifunctionality in practice. Here, we mapped landscape changes and interviewed farmers (n = 274) to examine the diversity of agricultural development pathways in 17 study sites across Europe over the last 20 years (2000–2020). We also assessed the associations between the development pathways and farmers’ perceptions of socio-economic outcomes, namely job satisfaction, societal valuation, and economic performance. Farm-level development was largely aligned with productivist pathways, while landscape-level changes aligned more closely with an increasing multifunctionality pathway. Farmers on pathways of increasing multifunctionality did not perceive improved outcomes on livelihood indicators as compared to productivist farmers. Furthermore, farms on increasing multifunctionality pathways were concentrated in sites with very high management intensities that face strong pressure from environmental regulations, as well as low-intensity, mountainous sites, where opportunities for intensification are limited. These results suggest that current pathways that increase multifunctionality arise mostly by necessity. Successful agricultural transformation will therefore require policy to create enabling environments that provide socioeconomic benefits for farmers to increase multifunctionality, and a civil society and market conditions that value sustainable agriculture.

The ‘Aarhus Convention’ – regulating access to environmental information, public participation and justice in environmental decision−making – is a key international agreement with a long history and a considerable number of signatory countries. While implementation has been studied nationally, there is little comparative research at the transnational level. Based on ten criteria, we analysed national implementation reports of the 2014, 2017 and 2021 reporting cycles in terms of how 33 countries in Europe have implemented the access to information and public participation pillars, and identified obstacles they encountered. We also studied similarities and differences supra-nationally. Overall, countries are quite successfully fulfilling the obligations of the two pillars. Most obstacles reported concern four criteria: access to information, information provision, interaction, and trust. Implementation practices have changed little from 2014 to 2021. However, East- and South-European countries report more, and more persistent or repetitive obstacles, compared to Northern and Western European countries. The national democratic context seems to affect the quality of implementation. The Convention’s compliance bodies and national agencies responsible for coordinating the implementation are encouraged to interact more closely, to account for the differences and leverage implementation.

Background: Recycling nutrients and organic matter available as waste in urban areas may close nutrient gaps and improve soil quality, but the concentrations of potentially toxic elements (PTEs) are commonly higher than in mineral fertilisers. How quickly may the limits for soil quality be exceeded, and for which elements, if such materials are applied intensively? For a rough answer to this question, we used soil data from ten case farms near Oslo and Bergen (Norway) to estimate how PTE concentrations increased when the demand for nitrogen (N), phosphorus (P) and potassium (K) in a theoretical carrot crop produced every year was covered by compost or digestate from source‑separated food waste, or composted garden waste, compared with manure from horses and poultry which are often kept in peri‑urban areas. Results: With the intensive fertilisation assumed here, the Norwegian soil quality limits for PTEs were reached within 20–85 years, and faster for soil with more organic matter since regulatory limits set by weight discriminate soils with low bulk density. The limits were reached first for Cu and Zn, which are both essential micronutrients for crop plants. The concentrations of macronutrients in the urban waste‑based fertilisers were not well balanced. Rates covering the K demand would lead to high surpluses of P and N. In peri‑urban vegetable growing, high applications of compost are not unusual, but more balanced fertilisation is required. Conclusions: The Norwegian regulations for PTEs in organic soil amendments and agricultural soil are stricter than in the EU, and do not support recycling of organic matter and nutrients from urban waste. Many materials which can only be applied with restricted amounts to Norwegian agricultural soil, may be applied according to crop demand in the EU. Growers utilising urban waste‑based fertilisers intensively should monitor the soil regularly, including PTE analyses. Soil sampling should occur on fixed sampling points to reveal changes in concentrations over time. Norwegian authorities should consider a revision of the organic fertiliser regulation to support recycling of valuable organic materials. There is a need for more data on the PTE concentrations in agricultural soil and organic fertiliser materials.
