By estimation, in 2050 cities will consume 80% of the food. On the other hand, Asia is responsible for more than half of global food losses and waste. Cities are the best place to not only influence nutrition resources and food waste management but also improve the associated quality of life of residents. In Asia, however, there is a lack of data and analysis on the components and data available for the food system within a city. The potential and feasibility of food waste-to-resource have not yet fully explored and analysed. The synergy between the food system and wastewater on nutrients (such as phosphorus) has not yet been systematically developed. While local governments are responsible for food waste management and local food system stability, yet a practical and systematic approach is urgently in need to implement actions.
