There have been dramatic changes to this Suffolk coast for millennia. Now sea level is rising once again and the region is also gently subsiding, whilst the climate becomes less stable. What might change along this coast over the next 50-100 years? And what steps are being taken to protect it? This is Hazlewood marshes and were drained centuries ago to be grazing marsh. But the embankment protecting these 100 acres was breached in the tidal surge of December 2013. They have returned to be part of the estuary, leaving hedgelines like this the only sign that they were once fields.The shore at the RSPB Minsmere reserve looking south. Sizewell B nuclear power station and the new Sizewell C site are in the background. The new site is having a massive sea-defence built. But parts of the RSPB reserve, on the floor of this gentle valley may gradually be flooded by the rising sea. The beach is shrinking and where I stand to take the photo at the northern end, may begin to breach. What steps are being taken to protect the reserve? If part of it does go, will there be new habitat for the protected species, especially the birds, to move to?Dunwich village and the shore looking south. This place shows how some places have been affected by coastal change in the past. Dunwich was once one of the largest ports in England. But the sea ate away at the coast, whilst the shingle spit grew south, reaching the cliffs and became the barrier beach I am standing on. That shut off the entrance to the river and to Dunwich’s port. The river cut a new route through the shore some miles north (far behind the viewer), leaving Dunwich to become a quiet backwater. There is a great little museum in the village that is well worth visiting.
