Water shortages on glitzy Capri became so dire that local authorities temporarily banned ferries from offloading tourists on to the island. A lack of rainfall tells only half the story. Decrepit infrastructure is as much to blame, with over 40% of Capri’s drinking water seeping out through leaks in its pipe network before it reaches customers.
