"The result of this was that, after a time the topsoil was blasted way by the east wind, leaving the area useless for crop-growth
virtually all the east Norfolk coast is now a second-home commuter area which has its own problems as the holiday homes along the coast are now falling into the sea due to coastal erosion.
The land is now longer regarded as valuable for farming so the drains and small rivers are not looked after unless they have a tourist value for boats."

If you want to call the above rational, it is not unreasonable for me to request proof. I can find nothing to support your statement that the land in Norfolk is useless for crop growth. In fact land prices suggest a total opposite. How   do you explain the prices paid for useless land. Your story is a total fabrication.
