Food losses and waste occur throughout the food supply chain from production to consumption. Globally about 1.3 billion tonnes of food, or roughly one-third of total food produced, is lost or wasted each year. Losses in developing countries primarily occur during production, storage, and transportation due to limitations in infrastructure and technology. In developed countries, waste mainly happens at the retail and consumer levels due to issues like consumer behavior and confusion over product date labels. Reducing losses and waste could help improve global food security while also protecting environmental resources.
