The UN says that more than enough food is being produced to feed the world, but almost a billion people remain undernourished.
Why is food not reaching those who need it most?
Researchers say the average household in the UK, for instance, throws away approximately five tons of edible food each year.
Supermarkets in developed countries regularly toss out large quantities of overstocked food that is still fit to consume.
But food waste is not just a problem for wealthy nations. In the developing world, as much as 30 per cent can be lost just getting food from farms to the marketplace, due to poor technologies for storing and shipping food.
