Rome, January 2 - Italy's 10.8% unemployment rate is due to climb in 2013 to 11.4%, as the gap widens between north and south, according to a report Wednesday. The study, compiled by the national union of chambers of commerce Unioncamere and research company Prometeia, said southern regions faced an 18% jobless rate on average. Calabria will be hit the hardest with 20.6% unemployment this year, followed by Sicily at 19.6% and Campania at 19.3%, the report predicted. Trentino-Alto Adige, the small region bordering Austria, faces 5.8% unemployment, the lowest in the country, according to the study. Ferruccio Dardanello, the president of Unioncamere, said there were "some signs of recovery" in the year ahead. "For this reason we need to redouble efforts to give a boost in confidence to Italians," he added. "We absolutely need to revive investments, without which there can be no sustainable development, as well as the internal market, which depends on a real recovery in employment levels".
