As part of the preparation for the new London Plan, arguably one of the most controversial elements of the proposal are targets for building 880,000 new homes and a review of the greenbelt to accommodate this. Campaigners have suggested that this could drive further land speculation and land banking, increase the immense pressure from housing developers and risk more viable farmland being left idle or lost permanently.

In Sustain’s response to London’s planning consultation they highlight the huge opportunities presented, showing how the planning system and the Green Belt could contribute to health, resilience and the sustainability of London’s food system, while helping the Mayor achieve London’s climate and biodiversity targets. As food security becomes an increasing priority, Sustain suggests the Mayor of London regard green belts around cities as "food resilience zones" and ensure land is assessed for its capacity to produce food in planning decisions. 

Rachel Dring, Capital Growth Coordinator at Sustain comments,

“We realise there will be difficult choices to make and competing demands for how we use land in a city like London, but we want a more progressive approach in the next London Plan.  Sustain believes and have seen how we can create a multi-use approach, where land simultaneously provides healthy, planet friendly food, enhances wildlife, creates jobs and skills and create public amenity. Where additional housing is needed, access to healthy food, nature and green spaces should all be considered and designed in.  And above all we need to see that London’s food security is prioritised, so we are prepared for shocks and challenges in the future. We outline how the London Plan can do all this in our response.”

The Mayor’s house building targets will also mean more high-density housing, which makes the need to integrate green space, food growing and community food infrastructure into developments ever more urgent, to ensure healthy, nature-rich, climate-resilient places to live. The new draft of the London Plan, due in 2026, presents an opportunity to address pressing concerns for London’s food security whilst also creating healthy food environments.

Sustain would also welcome a refresh of the London Food Strategy and implementation plan to be developed alongside the London Plan, which together would provide a framework that integrates spatial, infrastructure and policy both for business and community resilience and recognises the complexity, scale and impact of food systems on the UK’s largest urban population.
