​How to develop a resilient UK food system that contributes to net zero while promoting healthy diets? This theme focuses on the need for dietary and food system change to contribute to a net zero UK, while promoting access to healthy and affordable diets.

What should we grow in the UK? This theme focuses on the productive utilisation of our finite land resource. It covers questions of how crop and animal breeding and husbandry can help ensure sufficient food is produced from less land, and how space can be created for ambitious targets for planting trees to sequester carbon.

Where should our food come from? This theme focuses on the geographical scales at which our agri-food system operates and the balance between food produced and traded locally, nationally and across national borders. It covers questions of food security, reliance and sustainability of markets and supply changes at different spatial scales.

How should we change land use and land management in the UK? This theme focuses on the mechanisms and incentive systems to drive required changes in land use and land management in the UK. It covers questions of agricultural support policies, new markets for carbon sequestration (trees and soils), land use frameworks and reconciling demands of net zero, biodiversity and other environmental services).

How can we develop a more circular UK food system, including the agricultural economy and ecology, other components of the system, and the infrastructure that underpins it? This theme focuses on the question of more sustainable agricultural production systems with a particular emphasis on the concepts of circularity. It covers questions of the need for smaller-scale, mixed farming systems and the relative merits of systems such as agroecology, agroforestry and regenerative agriculture, and the re-use of nutrients from along the supply chain.

Individual and institutional behaviour change in the UK agri-food system. This theme focuses on the role of institutions and policies to encourage behaviour change in the agri-food system. It includes questions of politics, economics and psychology, and the individual and institutional dynamics of changes in food production practices and diet.
