France's river Loire, famous for the hundreds of castles gracing its shores, is a shallow river at the best of times, but this year even its flat-bottom tourist barges can barely navigate waters greatly reduced by a record drought.
Even some 100 kilometers from where the Loire empties into the Atlantic Ocean, sand banks now stretch as far as the eye can see, large islands connect to the shore and in places people can practically walk from one side of the river to the other.
