Should we be allowing the building of new housing on arable farmland and greenbelt?

The UK faces a severe housing shortage, with housebuilding rates lagging demand amid a population of over 67 million. Greenbelt land, designated to prevent urban sprawl, covers about 13% of England while high-quality arable farmland supports domestic food production at a time of global supply risks. Recent proposals from mayors and the government to release some protected land for homes have sparked opposition over loss of countryside and agricultural capacity.
