In addition to known problems, observers point out most EU presidencies find themselves forced to deal with unplanned events such as the Russian-Georgian war last fall or the energy crisis at the beginning of this year.
"I recently read that we are about to face a water crisis too and I thought, why not -- let's add that one to the list as well," said Swedish Prime Minister Fredrik Reinfeldt, a few weeks before beginning the job.
