British food security after industrialisation

The claim that Britain could feed itself depends on the area and labour force being counted. Including Ireland makes self-sufficiency across the British Isles more plausible in many years, but it would require a much larger share of the population to work in agriculture. Industrialisation drew people toward shipyards, mining and urban work, making food imports part of that economic choice. Cultivating additional marginal land becomes increasingly labour-intensive where machinery cannot operate. Wartime farming expanded acreage and sugar-beet production, although shortages reduced access to some fruits and other imported foods. The Yorkshire Dales example connects agricultural retreat with industrial employment in York and Leeds, followed by renewed cultivation in both world wars. A panelist also recalls ecological damage when wartime planting displaced wild grain and the species that had adapted to it.
