asked the Secretary of State for Scotland what is the extent of Scottish self-sufficiency in major foodstuffs, as reflected by Scottish production and Scottish patterns of consumption.

There is no control of movements of foodstuffs between Scotland and England and it is not possible, therefore, to produce accurate figures of Scottish self-sufficiency. Non-temperate products, sugar and maize are wholly imported, as is virtually all protein for animal feed. Self-sufficiency for a number of home-produced foodstuffs is shown below, based on Scottish production estimates and consumption patterns indicated by the National Food Survey. The estimates are for a three-year period centred on 1973; since then the figure for beef will have risen, that for liquid milk will have remained unchanged and those for other products will have fallen marginally.
