The December edition of the journal Nutrition Bulletin, published by the British Nutrition Foundation, examines the complex nutrition and health factors associated with the challenge of achieving a sustainable and secure food supply.

This report builds upon the Growing food in cities report. Whereas the emphasis of Growing food in cities was very much on the potential benefits of urban agriculture, this report focuses on what the actual benefits have been, and on the feasibility of developing food growing activities further, given London's specific social, economic and environmental context.

On 4 November 2008, the Mayor of London, Boris Johnson, and Rosie Boycott, Chair of London Food, launched a scheme to turn 2,012 pieces of land into thriving green spaces to grow food by 2012. The Capital Growth project aims to identify suitable patches of land around London and offer financial and practical support to groups of enthusiastic gardeners or organisations who want to grow food for themselves and for the local community.
