One difficulty is the huge number of sites the agency is responsible for:
Unesco insists all its sites adhere to strict rules about management and planning, but could it be that the task facing the organisation – effectively to protect the planet – has become so daunting as to be impossible? If it has, the man in charge must have one of the toughest jobs in the world. Speaking from his Paris office, Francesco Bandarin admits it's a tall order. "Sometimes you feel it's impossible to control everything, especially when you look at our founding principles," he says. "Our list is growing and the number of requests is growing, and it seems like the more work you do the more you get. It's a very big job – too big."Bandarin suggests a solution would be to maintain a central committee, but to break some of the bureaucracy by handing partial autonomy to an "effective network of heritage institutes". Unesco has launched a review of its practises and Bandarin expects big changes by 2012, when World Heritage turns 40. "It's the only way we can cope with the crazy volume of work," he says.
