Have We Reached "Peak Farmland?" (DOOOOOOM)

The amount of land needed to grow crops worldwide is at a peak, and a geographical area more than twice the size of France will be able to return to its natural state by 2060 as a result of rising yields and slower population growth, a group of experts said on Monday.

Their report, conflicting with United Nations studies that say more cropland will be needed in coming decades to avert hunger and price spikes as the world population rises above 7 billion, said humanity had reached what it called "Peak Farmland".

More crops for use as biofuels and increased meat consumption in emerging economies such as China and India, demanding more cropland to feed livestock, would not offset a fall from the peak driven by improved yields, it calculated.

If the report is accurate, the land freed up from crop farming would be some 10 percent of what is currently in use - equivalent to 2.5 times the size of France, Europe's biggest country bar Russia, or more than all the arable land now utilized in China.

"We believe that humanity has reached Peak Farmland, and that a large net global restoration of land to nature is ready to begin," said Jesse Ausubel, director of the Program for the Human Environment at the Rockefeller University in New York.

"Happily, the cause is not exhaustion of arable land, as many had feared, but rather moderation of population and tastes and ingenuity of farmers," he wrote in a speech about the study he led in the journal Population and Development Review.

The doom tag is just for James.
