Land Sparing Versus Land Sharing: Implications for Wildlife Welfare

The debate between concentrating intensive agriculture on smaller areas to spare land for wildlife versus lower-intensity farming across larger areas has significant implications for the welfare of wild animals.

Key Facts

Land sparing proposes intensifying agriculture on existing farmland to produce more food per hectare, freeing land for wildlife reserves
Land sharing proposes lower-intensity farming integrated with wildlife habitat, maintaining wildlife populations within agricultural landscapes
Research suggests land sparing produces better outcomes for most wildlife species in high-income countries when spare land is protected
Wildlife in intensive agricultural landscapes experiences chronic stressors including pesticide exposure, noise, and habitat fragmentation
The welfare implications of each strategy differ: land sparing concentrates production impacts on fewer animals, while land sharing spreads lower-intensity impacts across more

Welfare Considerations

The land sparing versus land sharing debate has profound implications for the welfare of wild animals at landscape scale. Intensification on a fraction of farmland that enables true rewilding of the remainder may produce a larger total habitat area supporting wildlife populations with access to natural behaviours. Wildlife living in extensively farmed landscapes may experience lower individual stress than those in intensively managed areas but may also face chronic low-level stressors from pesticides, noise, and simplified habitat. The welfare calculus depends on species-specific responses, the quality of spared land protection, and whether intensification genuinely enables meaningful rewilding rather than simply clearing farmland for development.

What You Can Do

Support food system policies that evaluate both production efficiency and wildlife welfare outcomes
Engage with agricultural land use planning discussions in your region to raise wildlife welfare as a criterion
Choose food produced using regenerative or lower-input methods that maintain biodiversity within farming landscapes
Donate to land trusts and conservation organisations that protect genuinely rewilded land freed from agricultural pressure
Advocate for research into wildlife welfare outcomes under different agricultural land use strategies
