But I have never found more compelling numbers than those related to food. In a world where 842 million people go to bed hungry every night, we actually produce sufficient food to provide, on average, 2,700 kilocalories every day, for everyone. In this same world:
Between one-fourth and one-third of the nearly 4 billion metric tons of food produced annually for human consumption is lost or wasted.
Asia and Africa account for about 67% of all food lost and wasted, globally.
North America and Oceania lose and waste almost half of what they produce: 42%! More than half of food loss and waste in developed countries happens during consumption — usually as a result of a deliberate decision to throw food away.
- Developing countries lose an average of 120 to 220 kg of food per person per year, which means that even regions ridden by undernutrition, such as South Asia and Sub-Saharan Africa, lose as many as 400 to 500 kilocalories per person, every day.

The newly released February 2014 Food Price Watch describes these statistics as “astonishing.” Food loss and food waste are serious threats to food security. But they also represent a hugely inefficient use of resources. It is estimated that for each calorie of food wasted, an additional 7 to 10 calories of inputs that are needed to produce that calorie are also wasted. Furthermore, food losses and waste squander investments in agriculture; produce unnecessary greenhouse gas emissions; generate enormous inefficiencies in the use of water, energy, fertilizers, and land; and reduce the incomes of (typically small) farmers, while requiring (poor) consumers to increase their spending to satisfy minimum calorie intakes. In other words, food loss and waste matter for poverty.
But food loss and waste are much more than just numbers. They are not simply another embarrassment of the riches or ludicrous irony. This situation is a quintessential reflection of the world we live in today, and the world we may be leaving to generations tomorrow. Future breakthroughs in agricultural production and climate change will mean very little to global food security if we continue losing and wasting so much of the food we produce.
