Rising population will hit UK’s self sufficiency if government continues to ignore British food production, say NFU

More than half of the UK’s food will come from overseas within a generation, as a rising population and stalling farm productivity combine to erode what remains of the UK’s self-sufficiency, according to farming leaders.

The UK’s failure to produce more food will leave households more vulnerable to volatile prices and potential shortages, the National Farmers’ Union will say at its annual conference on Tuesday. The farming body will call on politicians to encourage new investment in farming, and develop a national plan for a higher degree of food self-sufficiency.
