World losing 2,000 hectares of farm soil daily to salt damage

28 octubre 2014

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 study. Today an area the size of France is affected — about 62 million hectares (20 percent) of the world’s irrigated lands, up from 45 million hectares in the early 1990s.
