Land sparing and land sharing
Definition In a land sparing approach production and
conservation are separated: one part of the land is
intensively used for agricultural production while
another part is strictly set aside for conservation.
Land sparing Land sharing
In a land sharing (also: wildlife-friendly farming)
approach production and conservation are integrated:
land is used less intensively for agricultural production
and thus allows to maintain some biodiversity
simultaneously. Figure 1 Land sharing and land sparing represent the endpoints of a continuum. In land sparing (left)
land use changes are abrupt and coarse grained whereas in land sharing (right) they are spatially
continuous and fine grained. Many European landscapes can be classified within both extremes (Fischer
et al., 2008).
Characteristics Land sparing Land sharing
Strong contrast between areas that are used for agricultural production and
those that are set aside for conservation.
Land is used for agricultural production and biodiversity conservation
simultaneously.
Agricultural land is generally homogeneous. Agricultural land is generally heterogenious.
Land cover and its value for biodiversity vary at a coarse spatial scale (see Fig. 1,
left).
Land cover and its value for biodiversity vary at a fine spatial scale (see Fig. 1,
right).
Protected areas are excluded from human activities. Ecological interactions
between nature and agriculture are of minor concern.
Human activities and nature are both part of complex social-ecological
systems. Interactions between nature and agriculture are of high interest.
Examples
• Farmed land includes patches of native vegetation
• Areas that are structured similarly to native vegetation
• High level of heterogeneity, for example, by growing different crops on
multiple small fields
• Retain features of habitats within fields, e.g. scattered trees, or at their
margins, e.g. flower strips
• Large individual fields
• Low crop diversity
• High inputs of fertilizers and pesticides
• Main objective: maximize economic efficiency
• Biodiversity is restricted to nature reserves
