Redesigning a food system based on the protein transition is seen as a key strategy to enhance sustainability. Our results showed that the protein transition indeed largely reduces land use by up to 91% or greenhouse gas emissions by up to 92% while producing healthy diets around the world. This environmental improvement was achieved by reallocatin...

Food systems are largely responsible for today’s anthropogenic environmental impacts. Transitioning towards a circular food system is seen as a promising solution to reduce land use (LU) and greenhouse gas emissions (GHGe). But what about biodiversity? The aim of this paper was to assess the potential of enhancing biodiversity in circular European...

Europe’s nitrogen (N) crisis demands innovative food systems solutions to improve N cycling. This study modelled the potential of different diets and circular fertilization strategies to enhance food system N use efficiency (NUE), reduce N surplus, and minimize reliance on synthetic N fertilizers. Results show that circularity helps to improve NUE...

In this short communication, we propose a framework that classifies methods for estimating crop nitrogen (N) input requirements along two dimensions: short-term versus long-term and current versus optimal crop management practices. The four resulting quadrants provide different perspectives on modelling methods, each distinctive in handling soil N...

Protein transition and circular food system transition are two proposed strategies for supporting food system sustainability. Here we model animal-sourced protein to plant-sourced protein ratios within a European circular food system, finding that maintaining the current animal–plant protein share while redesigning the system with circular principl...

The global food system is facing the challenge of producing sufficient nutrients to accommodate future demands within planetary boundaries, while reducing malnutrition. Although nutrient-rich seafood can play a prominent role in resolving this challenge, seafood from capture fisheries is currently partly wasted. Here we quantified the nutrient cont...

There is currently little agreement on the optimal ratio of animal-sourced (ASP) versus plant-sourced proteins (PSP) in sustainable human diets. We deployed a biophysical optimization model to find the optimal ASP:PSP ratio at current and recommended protein intake levels for the EU28 countries. Results show that the lowest environmental impact for...

Redesigning the European food system on the basis of circularity principles could bring environmental benefits for Europe and the world. Here we deploy a biophysical optimization model to explore the effects of adopting three circularity scenarios in the European Union (EU)27 + UK. We calculate a potential reduction of 71% in agricultural land use...

Understanding how to improve the accessibility and timely dissemination of weather and market information can help farmers adapt their management to climate change impacts. Our objective is to use Social Network Analysis (SNA) as a tool to identify potential opportunities for improving weather and market advisory dissemination to rural communities...
