Questions posed:

• Mud origin in the Belgian Coastal Zone• Climate change and sediment budgets• Integration of data sets, of use for management purposes

Also

• Sources of sediments• Transport rates and pathways• Areas of deposition

Consequences on the coastline

• Erosion of the coastline because of sea level rise

• Changes in wind patterns and storms leading to increased/changed ersoion patterns

• Changes in wave patterns and extreme events

• Increase in flooding risk for shallow areas

• Reduced effects of existing coastal protection (dikes)

• Salt water intrusion in ground water

• Increased pressure on sluice capacities

• Influence on harbour constructions

Some concluding remarksTo mitigate the impacts of climate change on the coast, the general point of view is adaption

We need to improve today’s management to address tomorrow’s challenges

Climate change is an added dimension to coastal management

Climate change effects must to be integrated in ICZM

SUGGESTED WAYS FORWARD(on a regional scale)

• Public Awareness

• Establishment of coastal observatories

(e.g. Channel Coastal Observatory (CCO), Southampton

www.channelcoast.org

• Industry/Academia linkages and collaboration (e.g. marine climate

change impacts - www.mccip.org.uk/arc

• Training and education in coastal processes and management

A growing list of partners

Sponsoring partners

MCICP is a partnership between marine scientists and sponsors from government, its agencies and NGOs. The principal aim of the partnership is to develop a long-term multi-disciplinary approach to understanding the implications of climate change in our seas:

Scientific partners

The following organisations contribute to the work of MCCIP through the provision of scientific expertise on marine climate change issues.
