evidence: The UK produces a significant proportion of its other crop needs, including around 60% of sugar beet, 70% of potatoes and 80% of oilseeds. Apart from a recent pest-related reduction in oilseeds, these proportions have remained stable over the last ten years. Climate change represents a risk to production both in terms of making conditions unsuitable for some crops and allowing new pests to proliferate but it may also benefit new types of crops. [...] The UK grows roughly 15 million tonnes of wheat annually, occupying nearly 2 million hectares with some of the highest yields in the world at around 8 tonnes per hectare. The 2018 financial value of wheat produced in the UK was roughly £2 billion, representing a significant contribution to the total value of £9.3 billion for all crops produced by the UK that year. [...] Sustainable production methods ensure the UK’s long term food security by protecting the natural capital embedded in healthy soil, water, and biodiverse ecosystems. Food security rests ultimately not on maximising domestic production (which is market driven), but on making best use of land types which vary in quality and potential uses. Balancing and integrating food production with environmental factors supports efficient and sustainable land use without offshoring harms associated with lower production standards. Following the UK’s departure from the EU, new government incentives are being developed or considered across the four UK nations to support sustainable production.
