As East Anglia’s sea defences crumble they need to be replaced by something more resilient. Salt marshes may be the answer
Many of the coastal sea defences erected after the 1953 flood that killed 307 people in Norfolk, Suffolk, Essex and Lincolnshire are disintegrating through age, and need to be replaced. However, with a sea level rise of up to 1.15 metres, or possibly more, this century, and increasingly violent storms forecast, then simply rebuilding them or making them higher is too expensive to be a viable option. Since tourism and access to the sea are vital, and the benefits to birdlife and fish nurseries that the region’s marshes represent are valuable assets, then a different way has to be found.
