Ecology: Conservation and food system changes needed to bolster biodiversity
Trees, shrubs and debris are burned on the Canadian prairies to make way for more cropland. A PinP photo. Nature Declines in terrestrial biodiversity from habitat conversion could be reversed by adopting a combination of bold conservation methods and increases in the sustainability of the food system, a modelling study published in Nature suggests. Human pressures, such as the destruction of natural habitats to make way for agriculture and forestry, are causing rapid declines in biodiversity, and placing at risk the ecosystem services upon which we depend. Ambitious targets for biodiversity have been proposed, but it is unclear how these targets can be achieved whilst retaining the ability to feed a growing population. Using land-use and biodiversity models, David Leclère and colleagues show how this is possible. Conservationists need to increase the amount of actively managed land, restore degraded land and adopt generalized landscape-level conservation plann
