One third of globally produced food is lost (at production, harvest, storage and processing the stages) or wasted (at consumption points ) thus costing the global economy more than US$ 1 trillion in losses per year and exacerbating poverty and hunger. Food waste lowers the profit of food producers and increases the cost on consumers, which in turn reduces access to food and undermines food and nutrition security. Moreover, the environmental costs of food loss and waste amounts to US $700 billion.
Urban Food Systems
Many cities are faced with the challenge of rising urban food insecurity and the growing problem of rising food waste. In 2015, 19.8% of the urban population was moderately food insecure and 7.3% severely food insecure (WB and FAO, 2017). The increasing high consumption of packaged and ultra-processed food with low nutritional value has not only led to a rise in obesity, micronutrient deficiency, and diet-related non-communicable diseases, but is also driving the unsustainable agricultural expansion.
