The three ambitions will have greatest impact if pursued simultaneously. Designing and marketing food products that appeal to people using more locally available and seasonal ingredients would increase cities' connection with local farmers and could help spark the transition to regenerative practices. Using more local ingredients would likely increase the traceability of food and therefore potentially its safety. Similarly, making the compost and fertilisers derived from food by-products attractive to peri-urban farmers would help drive efforts in cities to collect and make the most of these by-products and other organic materials. As hubs of innovation and connectivity, cities are ideally placed to successfully link up all elements of the food value chain.
