Global environmental change presents both old and new challenges. A far more systematic application of existing science in the entire food chain is essential to meet future food needs. While this is daunting enough in itself, new questions present themselves through changing food habits and global environmental change. The immediate challenge is to adapt plant, animal and food systems to changing temperature, nutrient and water conditions. To develop sustainable food systems in the long term, the paper discusses a set of considerations such as food demand response, resource efficiency, GHG emission limits and provisions to reduce vulnerability. Finally, some factors are presented to reframe the nature of food systems: multifunctionality, globalisation, food and fuel prices, consumer behaviour and state support to food production.
