The rise in food prices which I first wrote about last week could create significant problems or right some wrongs, according to an article in The Economist. Since last spring, the cost of wheat, maize, milk and oilseeds (to name only a few) have increased substantially, with The Economist's food-price index higher now than any other point since its inception in 1845.

The industry has even coined the term "agflation" to describe the situation and the picture experts are painting isn't a pretty one. With government intervention and the right decisions such as aiding the rural poor and reducing farming subsidies, the wealth of poor nations could improve exponentially. On the flip side, the wrong decisions could spell disaster for the urban poor.

Three-quarters of the world's poor live in rural areas. The depressed world prices created by farm policies over the past few decades have had a devastating effect. There has been a long-term fall in investment in farming and the things that sustain it, such as irrigation. The share of public spending going to agriculture in developing countries has fallen by half since 1980. Poor countries that used to export food now import it.

Reducing subsidies in the West would help reverse this. The World Bank reckons that if you free up agricultural trade, the prices of things poor countries specialise in (like cotton) would rise and developing countries would capture the gains by increasing exports. And because farming accounts for two-thirds of jobs in the poorest countries, it is the most important contributor to the early stages of economic growth. According to the World Bank, the really poor get three times as much extra income from an increase in farm productivity as from the same gain in industry or services. In the long term, thriving farms and open markets provide a secure food supply.

However, there is an obvious catch—and one that justifies government help. High prices have a mixed impact on poverty: they hurt anyone who loses more from dear food than he gains from a higher income. And that means over a billion urban consumers (and some landless labourers), many of whom are politically influential in poor countries. Given the speed of this year's food-price rises, governments in emerging markets have no alternative but to try to soften the blow.

Where they can, these governments should subsidise the incomes of the poor, rather than food itself, because that minimises price distortions. Where food subsidies are unavoidable, they should be temporary and targeted on the poor. So far, most government interventions in the poor world have failed these tests: politicians who seem to think cheap food part of the natural order of things have slapped on price controls and export restraints, which hurt farmers and will almost certainly fail.
