Geneva - Spreading deserts and degradation of farm land due to climate change will pose a serious threat to food supplies for the world's surging population in coming years, a senior United Nations scientist warned on Friday.
MVK Sivakumar of the UN's World Meteorological Organisation (WMO) said the crunch could come in just over a decade as all continents see more weather-related disasters like heat waves, floods, landslides and wildfires.
"Should we worry about land being degraded? Yes," Sivakumar, who leads the WMO's agricultural meteorology division, told a news conference in Geneva.
