Land Conservation Policies and Carbon Emissions from Land Cover Change 1: University of Bonn, Germany; 2: Potsdam Institute for Climate Impact Research, Germany; 3: Colorado State University, USA Biomass carbon losses from land use and land cover change have increased in recent decades, driven largely by agricultural land expansion. In response, governments worldwide have adopted a wide range of land conservation policies. Here, we assess how these public policies affect land conservation patterns and associated biomass carbon changes, at the global scale, across different policy schemes and climate zones. We further identify specific policy interventions that stand out as particularly effective. Using global geospatial datasets and a combination of econometric and machine learning methods, we estimate that land conservation policies have globally reduced losses of intact and non-intact forest by 30% and by 36%, respectively. In contrast, their effect on grassland conservation is less clear. The observed forest protection has been achieved through both environmental payment schemes and habitat conservation regulations. We further find that large-scale frameworks with financial and technical support from international organizations are critical for mitigating land-use emissions in the tropical regions, whereas integrated national policies that combine regulatory measures with payments are most effective in the temperate regions. | |
