Land Sharing and Land Sparing
Definition
Land sharing and land sparing are contrasting strategies for balancing food production with biodiversity conservation. Land sharing integrates biodiversity into lower-intensity, wildlife-friendly agricultural landscapes; land sparing concentrates production in high-yield areas so that other land can be left or restored as natural habitat. The dichotomy was formalised by Green, Balmford, Phalan and colleagues in the 2000s–2010s.

Overview
What it means
Empirical work in Ghana and India found that most species — especially habitat specialists — decline even under low-intensity farming, which can favour sparing; critics, notably Perfecto and Vandermeer's agroecological "matrix" perspective, argue that diversified farming landscapes sustain biodiversity and livelihoods and that real systems mix both strategies.
The framework has become a standard lens in conservation science, agricultural policy and land-use modelling, while its binary form is increasingly treated as a continuum.
How it is used
The framework structures research and policy debates on agricultural intensification, protected-area planning, agroecology and landscape approaches to sustainability.
Why it matters
How societies resolve this trade-off shapes the future of both food systems and terrestrial biodiversity. **Note:** Candidate 1591 ("Land sharing-sparing continuum") merges here.
