Identifying regional drivers of future land-based biodiversity footprints

Biodiversity footprints quantify the impacts on ecosystems caused by final consumption in a region, accounting for imports and exports. Up to now, footprint analyses have typically been applied analyze past or present patterns. Here, we future land-based biodiversity associated with three diverging Shared Socio-economic Pathways (SSPs), using loss Intactness Index (BII) as an indicator of loss. For each SSP, retrieved socio-economic land use projections 2100 from IMAGE-MAGNET model calculated seven aggregated world regions. We then compared these functional diversity component biosphere integrity planetary boundary. Our results indicate that global impact stays below boundary (tentatively set at 90% original BII) all scenario-year combinations. Contrastingly, per capita is transgressed one, four five out regions SSP1 (‘sustainability’), SSP2 (‘middle road’) SSP3 (‘regional rivalry’), respectively. These strong difference between SSPs. Even ‘sustainability’ scenario, North America needs be reduced meet Thus, policy-making safeguard environment would benefit adopting region-specific strategies: focusing realizing agricultural efficiency gains unexploited potential, while promoting dietary changes towards less animal-based limited potential additional gains.
