Aligning food production with biodiversity conservation is one of the greatest challenges of our time. One framing of this challenge is the land-sharing vs. land-sparing debate. Much empirical research has focused on identifying the relationship between agricultural yields and species populations, and using the relative number of species with particular relationships to inform landscape-level management. We feel this is misguided, as such an approach does not guarantee the existence of every…

Aligning biodiversity conservation and agricultural production in heterogeneous landscapes.

It is found that when species' abundance and agricultural yields vary across landscapes, the optimal strategy to minimize trade-offs is rarely pure land sparing or land sharing, and instead, landscapes that combine elements of both strategies are optimal.

Combined effect of matrix quality and spatial heterogeneity on biodiversity decline

The land-sparing/land-sharing debate remains an oversimplified framework to evaluate landscape management strategies that aim to reconcile food production and biodiversity conservation. Still,

Changes in agriculture-biodiversity trade-offs in relation to landscape context in the Argentine Chaco

Better balancing agricultural production and biodiversity conservation is a central goal for many landscapes. Yet, empirical work on how to best achieve such a balance has focused mainly on the local

Assessing the impact of grassland management on landscape multifunctionality

The tool presented can aid informed decision-making by predicting the impact of future changes in landscape composition, and by allowing for the relative roles of stakeholder priorities and biophysical trade-offs to be understood by scientists and practitioners alike.

The land sparing-sharing model provides a powerful heuristic and analytical framework for understanding the potential of agricultural landscapes to support wild species. However, its conceptual and

Land sharing versus land sparing—What outcomes are compared between which land uses?

Land sharing versus land sparing describes contrasting strategies to conserve biodiversity while maintaining agricultural production. We comprehensively reviewed empirical studies comparing

Land sharing complements land sparing in the conservation of disturbance-dependent species

Alteration of natural disturbances in human-modified landscapes has resulted in many disturbance-dependent species becoming rare. Conservation of such species requires efforts to maintain or recreate

Bird conservation and the land sharing‐sparing continuum in farmland‐dominated landscapes of lowland England

The results support intermediate or 3-compartment land-sparing strategies to maximize bird populations across lowland agricultural landscapes, and help define which groups of species are the target of conservation.

Reconciling Food Production and Biodiversity Conservation: Land Sharing and Land Sparing Compared

Compared crop yields and densities of bird and tree species across gradients of agricultural intensity in southwest Ghana and northern India, land sparing is a more promising strategy for minimizing negative impacts of food production, at both current and anticipated future levels of production.

Food and Biodiversity

Density-yield curves help evaluate whether land sharing or land sparing most benefits biodiversity, and draw on surveys of biodiversity in landscapes in Ghana and India to provide some valuable hard data to inform this discussion.

Key priorities for the future in this work are addressing issues when using the existing framework, and developing alternative, holistic ways to conceptualise challenges related to food, biodiversity, and land scarcity.

Closing yield gaps: perils and possibilities for biodiversity conservation

This work combines global data on yield gaps, projected future production of maize, rice and wheat, the distributions of birds and their estimated sensitivity to changes in crop yields to map where it might be most beneficial for bird conservation to close yield gaps as part of a land-sparing strategy, and where doing so may be most damaging.

Farming and the Fate of Wild Nature

It is shown that the best type of farming for species persistence depends on the demand for agricultural products and on how the population densities of different species on farmland change with agricultural yield, and that high-yield farming may allow more species to persist.
