Food prices rising due increases in meat consumption and biofuels

The Economist (Dec 6th 2007) writes about how global agricultural prices are Cheap no more:

economist on food prices

…what is most remarkable about the present bout of “agflation” is that record prices are being achieved at a time not of scarcity but of abundance. According to the International Grains Council, a trade body based in London, this year’s total cereals crop will be 1.66 billion tonnes, the largest on record and 89m tonnes more than last year’s harvest, another bumper crop. That the biggest grain harvest the world has ever seen is not enough to forestall scarcity prices tells you that something fundamental is affecting the world’s demand for cereals.

Two things, in fact. One is increasing wealth in China and India. This is stoking demand for meat in those countries, in turn boosting the demand for cereals to feed to animals. The use of grains for bread, tortillas and chapattis is linked to the growth of the world’s population. It has been flat for decades, reflecting the slowing of population growth. But demand for meat is tied to economic growth (see chart 1) and global GDP is now in its fifth successive year of expansion at a rate of 4%-plus.

Higher incomes in India and China have made hundreds of millions of people rich enough to afford meat and other foods. In 1985 the average Chinese consumer ate 20kg (44lb) of meat a year; now he eats more than 50kg. China’s appetite for meat may be nearing satiation, but other countries are following behind: in developing countries as a whole, consumption of cereals has been flat since 1980, but demand for meat has doubled.

Not surprisingly, farmers are switching, too: they now feed about 200m-250m more tonnes of grain to their animals than they did 20 years ago. That increase alone accounts for a significant share of the world’s total cereals crop. Calorie for calorie, you need more grain if you eat it transformed into meat than if you eat it as bread: it takes three kilograms of cereals to produce a kilo of pork, eight for a kilo of beef. So a shift in diet is multiplied many times over in the grain markets. Since the late 1980s an inexorable annual increase of 1-2% in the demand for feedgrains has ratcheted up the overall demand for cereals and pushed up prices.

Because this change in diet has been slow and incremental, it cannot explain the dramatic price movements of the past year. The second change can: the rampant demand for ethanol as fuel for American cars. In 2000 around 15m tonnes of America’s maize crop was turned into ethanol; this year the quantity is likely to be around 85m tonnes. America is easily the world’s largest maize exporter—and it now uses more of its maize crop for ethanol than it sells abroad.

Ethanol is the dominant reason for this year’s increase in grain prices. It accounts for the rise in the price of maize because the federal government has in practice waded into the market to mop up about one-third of America’s corn harvest. A big expansion of the ethanol programme in 2005 explains why maize prices started rising in the first place.

Ethanol accounts for some of the rise in the prices of other crops and foods too. Partly this is because maize is fed to animals, which are now more expensive to rear. Partly it is because America’s farmers, eager to take advantage of the biofuels bonanza, went all out to produce maize this year, planting it on land previously devoted to wheat and soyabeans. This year America’s maize harvest will be a jaw-dropping 335m tonnes, beating last year’s by more than a quarter. The increase has been achieved partly at the expense of other food crops.

Guess who loses
According to the World Bank, 3 billion people live in rural areas in developing countries, of whom 2.5 billion are involved in farming. That 3 billion includes three-quarters of the world’s poorest people. So in principle the poor overall should gain from higher farm incomes. In practice many will not. There are large numbers of people who lose more from higher food bills than they gain from higher farm incomes. Exactly how many varies widely from place to place.

Among the losers from higher food prices are big importers. … some of the poorest places in Asia (Bangladesh and Nepal) and Africa (Benin and Niger) also face higher food bills. Developing countries as a whole will spend over $50 billion importing cereals this year, 10% more than last.

In every country, the least well-off consumers are hardest hit when food prices rise. This is true in rich and poor countries alike but the scale in the latter is altogether different. As Gary Becker, a Nobel economics laureate at the University of Chicago, points out, if food prices rise by one-third, they will reduce living standards in rich countries by about 3%, but in very poor ones by over 20%.
