Loss of economic value: 750 billion US $ (FAO, EIU)

Why are food losses an issue?

Loss of nutritional value - kcal lost or wasted: 63% for roots and tubers, 42% for fruits & vegetables (WRI)

Environmental impact on climate and availability of resources (energy, water, land, nutrients)

●64 litres of water for 1kg of tomato Food security impact: even if just one-fourth of the food

currently lost or wasted globally could be saved, it would be enough to feed 870 million hungry people in the world (FAO)
