Many scientific studies have looked into cities’ food self-sufficiency potential. An article published in the Journal of Cleaner Production reviews this literature and shows that, on the one hand, that it is very difficult to compare such studies, and, on the other, that cities should focus on circular and sustainable practices rather than sufficiency.
FAO and RUAF have published a very comprehensive Toolkit called “Assessing and planning sustainable city region food systems”. This is the result of a 3 years journey with 7 cities to develop a methodology to analyse urban city food systems that any city around the world can apply.
With as high as 30% of global food being wasted, it is crucial to understand why households waste food. A recent literature reviews shows that, good news, no one is happy to waste food. If households know they should not waste food, then telling them not to do so will therefore not really have an impact. The secret rather lies in understanding, and acting upon, the interwoven set of factors that make people waste food even if they know they should not.
With the rise in awareness of food waste and its environmental implications as well as emerging discourses around a “sharing economy”, there has been renewed interest in food sharing practices. Researchers from the SHARECITY project have developed a typology of food sharing initiatives that shows that it goes beyond merely sharing food and it can take a variety of forms. Their work can inspire cities to develop a food-sharing ecosystem.
