Food prices are soaring worldwide - driven by fierce competition for reduced international supplies of wheat, maize and rice, and other agricultural commodities.

As concern grows over the risk of food shortages and instability in dozens of low-income countries, global attention is turning to an age-old crop that could help ease the strain of food price inflation.

The potato is already an integral part of the global food system. It is the world's number one non-grain food commodity, with production reaching a record 320 million tonnes in 2007. Potato consumption is expanding strongly in developing countries, which now account for more than half of the global harvest and where the potato's ease of cultivation and high energy content have made it a valuable cash crop for millions of farmers.

At the same time, the potato – unlike major cereals – is not a globally traded commodity. Only a fraction of total production enters foreign trade, and potato prices are determined usually by local production costs, not the vagaries of international markets. It is, therefore, a highly recommended food security crop that can help low-income farmers and vulnerable consumers ride out current turmoil in world food supply and demand.

In Peru, for example, the government has acted to reduce costly wheat imports by encouraging people to eat bread that includes potato flour. In China, the world's biggest potato producer, agriculture experts have proposed that potato become the major food crop on much of the country's arable land. India has plans to double its potato production.

Food of the future.

The International Year of the Potato is raising awareness of the key role played by the "humble tuber" in agriculture, the economy and world food security. But it also has a very practical aim: to promote development of sustainable potato-based systems that enhance the well-being of producers and consumers and help realize the potato's full potential as a "food of the future".

Over the next two decades, the world's population is expected to grow on average by more than 100 million people a year. More than 95 percent of that increase will occur in the developing countries, where pressure on land and water is already intense.

 A key challenge facing the international community is, therefore, to ensure food security for present and future generations, while protecting the natural resource base on which we all depend. The potato will be an important part of efforts to meet those challenges...

Potatoes are a truly global food

The potato has been consumed in the Andes for about 8 000 years. Taken by the Spanish to Europe in the 16th century, it quickly spread across the globe: today potatoes are grown on an estimated 192 000 sq km, or 74 000 square miles, of farmland, from China's Yunnan plateau and the subtropical lowlands of India, to Java's equatorial highlands and the steppes of Ukraine.

Potatoes feed the hungry

The potato should be a major component in strategies aimed at providing nutritious food for the poor and hungry. It is ideally suited to places where land is limited and labour is abundant, conditions that characterize much of the developing world. The potato produces more nutritious food more quickly, on less land, and in harsher climates than any other major crop - up to 85 percent of the plant is edible human food, compared to around 50% in cereals.

Potatoes are good for you

Potatoes are rich in carbohydrates, making them a good source of energy. They have the highest protein content (around 2.1 percent on a fresh weight basis) in the family of root and tuber crops, and protein of a fairly high quality, with an amino-acid pattern that is well matched to human requirements. They are also very rich in vitamin C - a single medium-sized potato contains about half the recommended daily intake - and contain a fifth of the recommended daily value of potassium.

Demand for potatoes is growingWorld potato production has increased at an annual average rate of 4.5 percent over the last 10 years, and exceeded the growth in production of many other major food commodities in developing countries, particularly in Asia.

While consumption of potato has declined in Europe, it has increased in the developing world, from less than 10 kg (22 lb) per capita in 1961-63 to almost 22 kg (48.5 lb) in 2003. Consumption of potato in developing countries is still less than a quarter of that in Europe, but all evidence suggests it will increase strongly in the future.
