Across the globe, one-third of the food we produce is wasted each year. That equates to some 1.3 billion tonnes of food, causing both economic losses and significant damage to the environment, according to the United Nations.
Where and how that food is wasted differs from country to country. In developing nations, most of the food waste occurs during the production phase (due to lack of sufficient refrigeration and poor infrastructure), with very little waste on the consumer side.
