World food demand is expected to more than double by 2050. Decisions about how to meet this challenge will have profound effects on wild species and habitats. We show that farming is already the greatest extinction threat to birds (the best known taxon), and its adverse impacts look set to increase, especially in developing countries. Two competing solutions have been proposed: wildlife-friendly farming (which boosts densities of wild populations on farmland but may decrease agricultural yields…

Land for Food & Land for Nature?

Opinions on how to limit the immense impact of agriculture on wild species are divided. Some think it best to retain as much wildlife as possible on farms, even at the cost of lowering yield…

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.

Assessing strategies to reconcile agriculture and bird conservation in the temperate grasslands of South America

Examining how bird population densities changed with farm yield in the Campos of Brazil and Uruguay suggests that increasing yields in some areas while reducing grazing to low levels elsewhere may be the best option for bird conservation in these grasslands.

The environmental costs and benefits of high-yield farming

This study argues that high-yield farming impacts should be measured per unit of production and shows that viewed this way, some land-efficient systems have less impact than lower-yielding alternatives, and suggests that trade-offs among key cost metrics are not as ubiquitous as sometimes perceived.

Land sparing to make space for species dependent on natural habitats and high nature value farmland

A novel ‘three-compartment’ land-sparing approach, in which about one-third of spared land is assigned to very low-yield agriculture and the remainder to natural habitats, resulted in least-reduced projected future populations for more species.

Achieving production and conservation simultaneously in tropical agricultural landscapes

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.

Sustainable Agriculture and Plant Breeding

World population is expected to increase from the current 6.7 billion to more than 10 billion people by the year 2050. This 45 % increase in the current world population will create demand for…

Agricultural farming alters predator–prey interactions in nearby natural habitats

Compared the foraging behaviours and abundances of the red fox and two species of gerbils, close to and distant from farms, and during two moon phases, could suggest that indicators of predation risk are not universal, and their effectiveness may depend indirectly on anthropogenic activities, such as agricultural farming.

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.

The results suggest that recent trends in agriculture have had deleterious and measurable effects on bird populations on a continental scale and predict that the introduction of EU agricultural policies into former communist countries hoping to accede to the EU in the near future will result in significant declines in the important bird populations there.
