Climate change and coastal defences

Naturally dynamic buffers require space

Sir, – The “strengthening of coastal defences against flooding” is not the only nor the best way forward in preparing for those unpredictable effects of climate change on Ireland’s coasts (“The Irish Times view on preparing for climate change: turning planning into action”, May 6th).

What is needed more than ever is for us to restore and safeguard our naturally dynamic coastal zone: low-lying coastal areas, sea-grass beds, salt marshes, and dunes.
