Climate change physical knowledge and sea level change in the northern Adriatic and the Venice Lagoon
Coastal zones have changed profoundly during the 20th century with increasing populations, economies and urbanization. Today, low-elevation coastal zones below 10m elevation contain about 10% of the world population. In the 136 port cities around the world with more than 1 million inhabitants there is a total population of 400 million people, of which about 10% are exposed to a 1 in 100 year coastal flood event.
In the 2009 World Heritage Report Case studies on climate change and World Heritage underlined that in the past Venice has been sinking at a rate of about 10 cm per century as a result of natural subsidence, i.e. the rise of water level caused by delta propagation and the compactness of sediments; but during the twentieth century, it lost an extra 10 to 13 cm.
UNESCO and ISMAR-CNR are organizing in Venice, Italy from 22 to 23 November 2010 an international scientific workshop titled “From Global to Regional: Local Sea Level Rise Scenarios - Focus on the Mediterranean Sea and the Adriatic Sea”. Will be discussed major controversial scientific issues on the topic and evidencing the scientific background and identify multiple plausible sea level rise scenarios by 2100 for the northern Adriatic Sea.
The workshop should draw helpful guidelines for the local authorities that are responsible for the implementation of major mitigation interventions. It will show the way to an International Conference on “The Future of Venice and its Lagoon in the context of Global Change” scheduled by UNESCO in 2011, which reflects its long tradition of scientific contribution to the world importance and relevance of Venice and its lagoon, recognizing it as a hot spot for issues connected with climate change.
