The Parliamentary Office for Science and Technology has produced a short but informative briefing note on environmentally sustainable agriculture: Research Briefing
The note places particular emphasis on the notion of 'natural capital'. As part of a new domestic agricultural policy, measures could be taken to achieve natural capital targets referring to the elements of nature that directly or indirectly produce value to people.
It also notes that the Conservative Party manifesto contained a proposal for a 25-year environment plan, but this was not included in the Queen's Speech. If it was proceeded with, it would have implications for a number of aspects of agricultural practice. Among them would be water pollution; greenhouse gas emissions (GHG) from crops and livestock; soil compaction from machinery and livestock; the effects of pesticide use on pollinators; and, the degradation and fragmentation of natural and semi-natural habitats.
