A number of farmers have lost a significant amount of land to increased rates of erosion.

Why have groynes been built at Mappleton? The Holderness Coast is the most rapidly eroding coastline in Europe.

The Holderness Coast

The coastline starts with blowholes, stacks and stumps at Flamborough, and culminates with Spurn head, a very large spit that runs across part of Humber Estuary.
