The English Channel is both the world’s busiest maritime thoroughfare and the main gateway to NW Europe. And it is likely to become busier as the traffic of goods and people between the UK and the Continent grows. The common problems generated by this vital artery strengthen the need for transnational co-operation , which will be tested by the EMDI project through pilot initiatives on a series of themes including tourism, integrated coastal zone management and higher education. The key objective of the 1.9 M euro project is the further development of the Trans-Manche Atlas, a product of earlier co-operation between English and French authorities, into a sophisticated Regional Data Tool that can be used by authorities and practitioners across the area. The lead partner on the project, which will develop the atlas using the latest advances in ICT is France’s Region Haute-Normandie. The sharing of data and analysis between the partners will help forge a better understanding of the strategic issues facing the areas bordering the channel, fostering greater European integration.
