Local or global, the request for a sustainable urban food system — •Steffen Kriewald, Prajal Pradhan, and Jürgen P. Kropp — Potsdam Institute for Climate Impact Research, Potsdam, Germany

The share of urban population has increased from 30% to 55% in the last sixty years and will further increase up to 65% by 2050. Hence, it is crucial to provide enough food for the growing urban population to ensure local, regional and global food security. For over 4000 urban agglomerations we investigated the possibility of regional food production to reduce dependency on global trade. Additionally we examined the main influencing factors which lead to a sustainable food supply, such as population growth, urban sprawl, diets - both in terms of quantity and composition as well as climate change. Introducing a spatially explicit urban footprint from food production we were able to identify regions where future expansion of agricultural areas is limited and intensification will no longer be an option due to the impacts of climate change.
