Food prices
The end of cheap food
Dec 6th 2007
From The Economist print edition
Rising food prices are a threat to many; they also present the world with an enormous opportunity
FOR as long as most people can remember, food has been getting cheaper and farming has been in decline. In 1974-2005 food prices on world markets fell by three-quarters in real terms. Food today is so cheap that the West is battling gluttony even as it scrapes piles of half-eaten leftovers into the bin.
That is why this year's price rise has been so extraordinary. Since the spring, wheat prices have doubled and almost every crop under the sun—maize, milk, oilseeds, you name it—is at or near a peak in nominal terms. The Economist's food-price index is higher today than at any time since it was created in 1845 (see chart). Even in real terms, prices have jumped by 75% since 2005. No doubt farmers will meet higher prices with investment and more production, but dearer food is likely to persist for years (see article). That is because “agflation” is underpinned by long-running changes in diet that accompany the growing wealth of emerging economies—the Chinese consumer who ate 20kg (44lb) of meat in 1985 will scoff over 50kg of the stuff this year. That in turn pushes up demand for grain: it takes 8kg of grain to produce one of beef.

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.
Over the past few years, a sense has grown that the rich are hogging the world's wealth. In poor countries, widening income inequality takes the form of a gap between city and country: incomes have been rising faster for urban dwellers than for rural ones. If handled properly, dearer food is a once-in-a-generation chance to narrow income disparities and to wean rich farmers from subsidies and help poor ones. The ultimate reward, though, is not merely theirs: it is to make the world richer and fairer.
