If urban farming has to be scaled up, how can this be done in the most resource-friendly way? Researchers have reviewed key urban waste streams and the way they can contribute to urban agriculture.
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.
