Poor irrigation has poisoned much of world's farmland with salts, study finds 30.10.2014 MinnPost
The Euphrates Basin in Syria and Iraq Australia's Murray-Darling Basin And why is it happening? In areas where rainfall is insufficient to sustain agriculture, farmers irrigate their fields with surface water or, more often, groundwater. Dissolved minerals in the water contain certain salts that aren't particularly troubling if they pass quickly through the soil and return to an aquifer. But soil drainage tends to be poor in dry regions, and water to be precious, especially on the "smallholder farms" that the UN report identifies as a chief source of the problem. These operations produce so little food that farmers have to supplement their agricultural income with other jobs, while teetering persistently at the edge of seeing their farms fail completely. So they use the water frugally, in ways that cause salts to accumulate even faster in the root zone, poisoning the plants. Sometimes the salt degradation reaches a level that turns the soil surface to a hard, impervious crust, keeping out whatever rain ...

World losing 2,000 hectares of farm soil daily to salt damage 28.10.2014 Environmental News Network
Salt-spoiled soils worldwide: 20% of all irrigated lands — an area equal to size of France; Extensive costs include $27 billion+ in lost crop value / year. UNU study identifies ways to reverse damage, says every hectare needed to feed world’s fast-growing population. Every day for more than 20 years, an average of 2,000 hectares of irrigated land in arid and semi-arid areas across 75 countries have been degraded by salt, according to a new study — Economics of Salt-induced Land Degradation and Restoration — published today by the UNU Institute for Water, Environment and Health (UNU-INWEH).

The Aral Desert: Once a Sea - Now, All Dried Up 27.10.2014 Environmental News Network
The Aral Sea is a well known environmental disaster zone. But this year, it got a whole worse, writes Anson Mackay, as its biggest basin dried up completely to expose a toxic, salty wasteland. With continuing irrigation and declining river flows due to climate change, the desert is only set to expand. The Aral Sea has reached a new low, literally and figuratively. New satellite images from NASA show that, for the first time in its recorded history, its largest basin has completely dried up. However, the Aral Sea has an interesting history - and as recently as 600-700 years ago it was as small, if not smaller, than today.
