The ultimate crop rotation

Excerpt:

In recent months, the Ethiopian government began marketing abroad one of the hottest commodities in an increasingly crowded and hungry world: farmland.

"Why Attractive?" reads one glossy poster with photos of green fields and a map outlining swaths of the country available at bargain-basement prices. "Vast, fertile, irrigable land at low rent. Abundant water resources. Cheap labor. Warmest hospitality."

This impoverished and chronically food-insecure Horn of Africa nation is rapidly becoming one of the world's leading destinations for the booming business of land leasing, by which relatively rich countries and investment firms are securing 40-to-99-year contracts to farm vast tracts of land.

Governments across Southeast Asia, Latin America and especially Africa are seizing the chance to attract this new breed of investors, wining and dining executives and creating land-leasing agencies and land catalogues to showcase their offerings of earth. In Africa alone, experts estimate that about 50 million acres -- roughly the size of Nebraska -- have been leased in the past two years.

The trend is driven in part by last year's global food crisis. Relatively wealthy countries are shoring up their food supplies by growing staple crops abroad. The desert kingdom of Saudi Arabia, for instance, is shifting wheat production to Africa. The government of India, where land is crowded and overfarmed, is offering incentives to companies to carve out mega farms across the continent.

Increasingly, though, purely profit-seeking companies are snatching up land, making a simple, if somewhat grim, calculation. As one Saudi-backed businessman here put it, "The population of the world is increasing dramatically, so land and food supplies will be short, demand will be higher and prices will rise."

The scale and pace of the land scramble have alarmed policymakers and others concerned about the implications for food security in countries such as Ethiopia, where officials recently appealed for food aid for about 6 million people as drought devastates parts of East Africa. The U.N. Food and Agriculture Organization (FAO) is in the midst of a food security summit in Rome, where some of the 62 heads of state attending are to discuss a code of conduct to govern land deals, which are being struck with little public input.

"These contracts are pretty thin; no safeguards are being introduced," said David Hallam, a deputy director at the FAO. "You see statements from ministers where they're basically promising everything with no controls, no conditions."

The harshest critics of the practice conjure images of poor Africans starving as food is hauled off to rich countries. Some express concern that decades of industrial farming will leave good land spoiled even as local populations surge. And skeptics also say the political contexts cannot be ignored.

"We don't trust this government," said Merera Gudina, a leading opposition figure here who accuses Ethiopian Prime Minister Meles Zenawi of using the land policy to hold on to power. "We are afraid this government is buying diplomatic support by giving away land."
