The extent of the world’s land affected by excess salt is set to increase rapidly with potentially devastating impacts on food production, research has found.
About 1.4bn hectares (3.4bn acres), amounting to 10% of global land, is affected by salinity, with a further 1bn hectares classed as “at risk”, a report from the UN Food and Agriculture Organization has found.
