CONCEPTUALIZING FOOD SYSTEMS FOR GLOBAL ENVIRONMENTAL CHANGE RESEARCH

By Dr Polly J. Ericksen, Environmental Change Institute, Oxford University Centre for the Environment, Oxford, OX1 3QY, UK

This collected evidence justifies a representation of food systems, which can be used to identify key processes and determinants of food security in a given place or time, particularly the impacts of environmental change. It also enables analysis of the feedbacks from food system outcomes to drivers of environmental and social change, as well as trade-offs among the food system outcomes themselves.
