Abstract
Closing nutrient cycles by bio-based fertilizer products (BFPs) can improve the environmental sustainability of food systems and facilitate a more circular economy. Although the theoretical potential for nutrient recycling has been explored in detail, BFPs still seldom replace mineral fertilizer products in practice. The aim of the present study was to explore the critical enabling and limiting factors for the use of BFPs as seen from the perspective of farmers, suppliers, and civil society. To this aim, qualitative interviews were conducted with seven conventional grain farmers, six suppliers of BFPs, and five representatives of civil society, limited to environmental non-governmental organizations. The presented results illustrate a mismatch between demand and supply. On the one hand, the interviewed farmers were only interested in using BFPs if they are practical to use, balanced with respect to nutrient contents, and potentially provide the same earnings as mineral fertilizers. Positive effects for soil quality were an important driver for many of the farmers. On the other hand, the suppliers of BFPs were generally not able to offer products that fulfilled the farmers’ demands without economic losses, and they emphasized that they have faced several regulatory challenges. Representatives of regional civil society organizations expressed concern that new technical solutions could cause new environmental challenges, and that BFPs could enable further intensification of livestock production. The central-level representatives from the same NGOs, however, were positive about that BFPs can solve environmental problems. Policy instruments will be needed to increase the adoption of PFPs. Fostering BFPs’ that contribute to a sustainable agriculture is important to consider when formulating these polices.

The MilKey project aims at assessing the environmental, economic, and social sustainability of European dairy production systems, and at identifying ‘win-win’ farming practices for sustainable and greenhouse gas (GHG) optimised milk production. In this context, a holistic model was developed to evaluate the sustainability of specialised dairy farms and was entitled DEXi-Dairy. This model has the potential of aiding the identification of GHG and nitrogen (N) emission mitigation options and assessing their effects across multiple sustainability aspects. DEXi-Dairy covers the three sustainability pillars, i.e., environmental, economic, and social. Based on the ‘DEX’ multi-criteria methodology, the model is detailed under the form of a tree structure represented by four main hierarchical layers, i.e., branches, principles, criteria, and indicators. DEXi-Dairy was built following a participatory and interdisciplinary approach by MilKey project partners. It was then tested on three case study farms from Ireland, France, and Germany, respectively, using data from 2020. The DEXi-Dairy indicator handbook describes the sustainability tree and selected indicators to assess dairy production systems over a production year. Overall, this document can be used as a basis to replicate and expand the sustainability assessment framework developed as part of the MilKey project.

DairyMix. Multi-criteria assessment, decision support and management tools for sustainable circular mixed farming systems for dairy production
A total of 10 research institutions from Europe and Latin America have joint forces to develop a tool for dairy farmers. The overall aim is to increase sustainability and reinforce climate friendly mixed crop and dairy production systems.

Visions and the consequences - analysing visions for Norwegian agriculture and its consequences for food security
In the FOSIP project (Visions and the consequences - analysing visions for Norwegian agriculture and its consequences for food security) we will assess and evaluate the foundation, support, opportunities, and limitations for the goal of increased agri-food self-sufficiency in Norway and assess how far an increase will contribute to improved national food security.

The role of diversified small-scale horticulture in a transition towards more sustainable food systems with healthier diets (SmallHort)
The aim of the project is to explore how food systems based on diversified small-scale horticulture can be developed to become more economically, socially and environmentally sustainable while also increasing in scale. This will provide benefits to nature, environment and public health.

Cultivating sustainable changes in livestock feed production and feeding practices (Feed&Feeding)
The project will evaluate various strategies for feed production and feeding practices to enhance the sustainability of Norway's food system and support national agricultural policy goals. These strategies include adjusting livestock diets, improving breeding and animal health, and introducing new protein sources for feed. The project will assess environmental impacts, such as land use changes, greenhouse gas emissions, soil carbon levels, nutrient balances, and biodiversity, as well as socioeconomic impacts, including food security, economic and social sustainability, and the viability of rural communities.
