Climate change is affecting countries in the 2 Seas area faster and to a greater extent than was previously expected. The rising sea level is a serious threat to the countries in this region. The crossing border Polder2C's project combines research, practice and education in a unique way.The Hedwige-Prosperpolder is transformed into new tidal nature. This offers the unique chance of using an existing levee for strength and emergency response testing.The Polder2C's programme focuses on four activities:- Flood Defence - do research on the strength of flood defences- Emergency Response - design new and better emergency response plans- Knowledge Infrastructure - formalise knowledge transfer and educate the next generation of water managers- Realisation of a field station
