Venice residents protest resumption of cruises
Venice and UNESCO concerns
The decision comes just days before UNESCO convenes over proposals to add Venice to its list of endangered heritage sites.
Venice was put on the prestigious list in 1987 after describing the city as an extraordinary architectural masterpiece.
But the UN body said last month the city needed a more sustainable tourism management.
World heritage under threat from global warming
Dresden
In 2002, a so-called 100-year flood put large parts of Dresden under water and threatened numerous cultural treasures. The baroque Zwinger palace was also flooded. The city founded a task force to be prepared for future extreme weather events. Today there are global efforts underway to use climate modelling to better plan for the protection of cultural monuments in the future.
