Rewilding vs Regenerative Farming: Which Supports More?

Rewilding supports more wild species per hectare, while regenerative farming supports more total biomass and human food production on the same land. The honest answer depends on your goal: if you want maximum native biodiversity, rewilding wins; if you want to feed people while restoring soil, regenerative farming wins.

Background: Two Different Visions for Land

Rewilding and regenerative farming both emerged as responses to industrial agriculture’s harms—soil loss, biodiversity decline, and carbon emissions. But they start from opposite assumptions.

Rewilding aims to restore natural ecosystems with minimal human intervention, often by reintroducing keystone species (like wolves in Yellowstone or bison in Europe) and letting natural processes shape the landscape. Regenerative farming keeps land in production but uses practices that rebuild soil health, such as no-till, cover cropping, crop rotation, and managed grazing.

The core tension: rewilding removes farmland, reducing food output; regenerative farming keeps producing food but usually supports fewer wild species than a fully restored ecosystem. Neither is “better” in absolute terms—they serve different priorities.

How Rewilding Supports Biodiversity

Rewilding’s main strength is habitat restoration. When farmland is abandoned and native vegetation regrows, populations of native plants, insects, birds, and mammals typically rebound. Large herbivores and predators create a cascade of effects—grazing creates open patches for wildflowers, carcasses feed scavengers, and shrubs provide nesting sites.

Examples include the Knepp Estate in England, where low-intensity grazing by free-roaming animals has boosted populations of nightingales, turtle doves, and purple emperor butterflies. Similarly, the Oostvaardersplassen in the Netherlands shows how large herbivores can shape a wetland ecosystem without continuous human management.

However, rewilding takes time. Species recovery can be slow, especially if source populations are distant or if the landscape is fragmented. It also requires large areas to be effective—small patches may not support top predators or maintain genetic diversity.

How Regenerative Farming Supports Soil and Food

Regenerative farming focuses on soil health as the foundation. Practices like no-till, cover cropping, and composting increase soil organic matter, which improves water retention, nutrient cycling, and microbial activity. Healthier soil also stores more carbon—a key climate benefit.

Managed grazing (often called holistic or adaptive grazing) mimics the movement of wild herds: animals are moved frequently to prevent overgrazing, which stimulates grass growth and builds root systems. This can increase soil carbon and improve pasture productivity.

Regenerative farms also support biodiversity, but usually less than rewilding. Field margins, hedgerows, and intercropping provide habitat for pollinators and beneficial insects. A well-managed regenerative farm may support more species than a conventional farm, but it won’t match a mature forest or prairie.

Carbon Sequestration: Which Stores More?

Both approaches can sequester carbon, but the rates differ. Rewilding forests and grasslands can accumulate carbon in biomass and soil for decades. Mature forests store large amounts of carbon in wood, but after a century or more, they reach saturation.

Regenerative agriculture can increase soil carbon relatively quickly (0.2–0.6% per year) but may plateau after a few decades. The total carbon stored per hectare is often lower than a forest, but the land continues producing food.

One study from the Rodale Institute (a long-running organic farming trial) found that regenerative organic agriculture could sequester more carbon than conventional no-till, but the numbers vary widely by climate, soil type, and management. Rewilding a former pasture may sequester more carbon over 50 years than keeping it in regenerative grazing, but the exact comparison depends on local conditions.

How to Choose: What Are Your Priorities?

If you own land or are advising on policy, the choice depends on your primary goal:

• Biodiversity conservation → rewilding is generally more effective per hectare.
• Food production → regenerative farming is necessary to feed a growing population.
• Carbon storage → both work; rewilding may store more in above-ground biomass, while regenerative farming builds soil carbon without ceasing production.
• Economic viability → regenerative farming generates income; rewilding may require public funding or carbon credits.
• Community and cultural landscape → regenerative farming maintains rural livelihoods; rewilding can be controversial if it displaces traditional farming.

A hybrid approach is also possible: rewild marginal land while farming the most productive areas regeneratively. Many landscapes are a mosaic of both.

Common Problems and Trade-offs

Rewilding faces public opposition when it involves removing livestock or restricting access. It can also take decades to see results, and some species may not return without active reintroduction.

Regenerative farming has a learning curve and may require upfront investment in new equipment or fencing. Transitioning from conventional to regenerative methods can temporarily reduce yields, which is a barrier for farmers with tight margins.

Both approaches are vulnerable to climate change: droughts, floods, and heatwaves can undo gains. No single practice is a silver bullet.

Frequently Asked Questions

Can you combine rewilding and regenerative farming?

Yes. Many farms set aside unproductive areas for rewilding while farming the rest regeneratively. This “land sharing vs. land sparing” debate is nuanced—some species thrive on farmland, others need wild corridors. A mosaic approach often yields the best overall outcome.

Does rewilding reduce food production?

Yes, if it replaces productive farmland. But rewilding often targets marginal land that is difficult to farm or low-yield. The global food system also wastes about a third of food, so some argue we can afford to rewild some areas without compromising food security.

How long does it take for rewilded land to become “wild”?

It varies. Grasslands can recover in a few years, but forests may take decades to a century to reach a mature state. Soil recovery can take even longer.

Is regenerative farming profitable?

Many farmers report lower input costs (synthetic fertilizers, pesticides) and improved soil resilience, but the transition period can be financially tight. Profitability depends on market access, local climate, and the farmer’s skill. Some studies show comparable or higher long-term profits, but results vary widely.

Which approach is better for climate change?

Both help. Rewilding can store carbon in trees and soil, while regenerative farming reduces emissions from synthetic inputs and builds soil carbon. The best choice depends on the land’s potential and the need for food. In many cases, a combination is most effective.

Does regenerative farming really increase biodiversity?

Yes, compared to conventional farming. Practices like cover cropping, reduced tillage, and creating field margins provide habitat for pollinators, birds, and soil organisms. However, the species richness is generally lower than in a rewilded ecosystem. The key is to design farms with biodiversity in mind, not just as a byproduct.
