Jon Thornes is a mixed farmer in the Lincolnshire Wolds, overseeing 3,000 acres of organic and regenerative farmland for a range of crops and livestock including pedigree Lincoln red cattle, Lincolnshire buff hens and Norfolk Black Turkeys. With the England Land Use Framework consultation underway, Jon shares why taking a ‘land sharing’ approach may be preferable to ‘land sparing’ when it comes to both nature revival and food production.

Rewilding isn’t a trade-off - it’s a new balance for food and nature

There’s a lot of debate about land sharing versus land sparing, but for me, the real question is: why do we see them as opposing choices? At South Ormsby, we don’t separate farming from nature; we work with it.

For too long, farming has been seen as an extractive process, taking from the land and leaving little behind. But what if we flipped the question? Instead of asking, “How much land can we spare for nature?” we should ask, “How can all land serve nature first?”

Rewilding for all land - but not all land should look the same

Rewilding isn’t about taking land out of use but restoring its ability to support life. First and foremost, every acre should provide biodiversity with food and a home. If it can also produce food for people in a way that supports rather than depletes life, even better.

This isn’t an all-or-nothing choice, rewilding is a spectrum:

  • Some land will be fully returned to nature, with no intervention, just the slow work of recovery.

  • Some will be organically farmed, ensuring soil, water, and biodiversity thrive alongside food production.

  • Some will be grazed in ways that mimic lost herbivore ecosystems, shaping the land while keeping natural cycles intact.

  • Some will need active restoration, tree planting, rewetting, or species reintroductions to rebuild balance.

If we shift our perspective from sparing land to sharing land in a way that works for nature, we can create a future where biodiversity isn’t an afterthought, it’s the foundation.

The consequences of rewilding: are we ready?

But this vision requires difficult choices. If we want to give more space to nature, we cannot expect to eat the way we do now. A food system built on intensive production and global supply chains will not support a landscape where food and nature coexist.

A few key shifts could allow for a better balance:

  • Cutting back on intensive feed production, halving the arable land used for animal feed and repurposing some grazing land for crops.

  • A 50% reduction in meat and 25% reduction in dairy. This still allows for high-quality, pasture-fed livestock while sharing more land with biodiversity.

  • A bounty of plant-based foods like grains, pulses, nuts, fruits, and vegetables grown regeneratively, feeding people directly instead of cycling through livestock.

  • A thriving countryside - where nature-friendly farming coexists with wild areas, supporting pollinators, carbon sequestration, and rich biodiversity.

This isn’t just theory. Models show that land use shifts like this could make the UK 80-85% self-sufficient in food while lowering emissions and enhancing rural economies through eco-tourism, carbon credits, and sustainable food systems.

These changes haven’t just benefited nature, they’ve enhanced the resilience of our farm.

Rewilding my farm

Bringing nature back into our farming system has been both rewarding and challenging. At South Ormsby, we’ve experimented with different ways to integrate biodiversity into food production, learning through trial and adaptation.

Some successes have been immediate. More crop rotation, resting fields and allowing wildflowers to establish have dramatically increased insect populations, supporting pollinators and farmland birds. Introducing rotational grazing with our Lincoln Red cattle has improved soil health, mimicking natural grazing patterns that stimulate biodiversity while producing high-quality, pasture-fed beef. These changes haven’t just benefited nature, they’ve enhanced the resilience of our farm.

Other challenges have taken longer to navigate. Restoring streams and wetlands has required careful management to balance water retention with productive land use, and reintroducing native hedgerows has meant balancing the time-intensive work of establishment with the long-term gains in wildlife corridors and soil stability. Meanwhile, the transition from conventional cropping to more regenerative practices has required a shift in mindset, accepting that nature works on its own timescale, not ours.

These experiences have reinforced our belief that farming and nature can thrive together but it takes patience, observation, and a willingness to let the land lead the way.

A new future: rewilding everywhere, not just in reserves

Rewilding isn’t something that happens in remote landscapes, it should be part of every farm, estate, and community. Some areas will be fully wild, others will practice agroecology and regenerative farming, but all can contribute to a future where food, farming, and nature work together.

How do we get there? By shifting support, policies, and mindsets to value both food and nature, not as competing interests, but as two sides of the same coin.

The future isn’t about picking sides. It’s about rethinking priorities.

Are we ready to make these choices?
