Comparing Regional Biodiversity Benefits of Investment Strategies for Land‐Use Change

摘要: The need for public investment to address loss of biodiversity in agricultural landscapes is well recognised, yet there little analysis the likely benefits land-use change regional or cost effectiveness different options. We estimated and scenarios over 50 years a farming area south-eastern Australia. Declines were predicted under status quo land use. Implementing actions improved only slightly, compared with Future differed between biodiversity-focused salinity-focused investment. Biodiversity equalled exceeded current much more extensive revegetation than catchment targets. Cost improvement varied greatly strategies. was effective when meet targets focused on salinity management rather high conservation value areas, because lower opportunity costs management. With enhanced investment, greater areas. Although improvements small changed system scenarios, their higher other scenarios. Regional scale areas will require increased stewardship payments economic incentives landholders.
