World leaders met in Rome last week to discuss coordinated international action to tackle the food price crisis currently causing widespread hunger and social unrest. The price of food commodities, such as rice and wheat, on international markets rose sharply in 2006 and 2007. Prices rose even more sharply in the first three months of 2008. In developing countries, where families spend as much as 60-80% of their income on food, such price increases have a dramatic impact.1 Low income countries that import more food than they export are worst affected. The UN Food and Agriculture Organisation described 36 countries in crisis and, of these, 21 are African countries.2 Within countries, the poorest groups, both urban and rural, are hardest hit.
The crisis is caused by several factors affecting the balance between the demand for food and the available supply. Poor harvests in Australia, some Asian countries, and parts of Europe have contributed. In addition, grain stocks were very low. There are also, however, important long term structural causes. Although experts broadly agree on the factors involved (many of which are interrelated), there is less agreement on which factors have had the greatest impact.
