A quarter of world's farmlands highly degraded, says UN http://apocadocs.com/s.pl?1322503436
The United Nations has completed the first-ever global assessment of the state of the planet's land resources, finding in a report today that a quarter of all farmland is highly degraded and warning the trend must be reversed if the world's growing population is to be fed.
The UN Food and Agriculture Organisation estimates that farmers will have to produce 70 per cent more food by 2050 to meet the needs of the world's expected nine billion-strong population.
That amounts to 1 billion tonnes more wheat, rice and other cereals and 200 million more tons of cow and other livestock.
But as it is, most available farmland is already being farmed, and in ways that actually decrease its productivity through practices that lead to soil erosion and wasting of water.
