摘要

巴西合法亚马孙地区拥有重要的森林资源，但受到利益相关者行为的威胁。地籍环境农村(CAR);使用农村环境登记处(Rural Environmental Registry)数据库，根据私有财产规模界定土地所有者的界限和类别。基于巴西年度土地利用和土地覆盖测绘项目(MapBiomas)和毁林监测项目(PRODES)数据，我们确定了2000年至2020年每两年一次的年度森林覆盖/覆盖损失概况。分析表明，非常大的土地所有者主导了car登记区域，森林砍伐受土地所有者类型的影响。特大土地所有者、大土地所有者、中等土地所有者、小土地所有者和极小土地所有者对森林砍伐的累积贡献分别为2 916 245.96、1 234 216.79、2 871 400.36、2 805 058.62和2 637 485.60 ha。非常大的土地所有者(占财产总数的1.7%)在他们的财产上有更多的森林，但造成了最大的毁林总量，通常与农业综合企业有关。小型和非常小的土地所有者数量较多(分别占财产总数的21.0%和68.3%)，但他们拥有的总面积较小，对森林砍伐的贡献较小。在森林砍伐控制政策和对可持续发展目标议程的承诺中，应考虑财产规模和土地所有权不对称。

Assessment of the effect of landowner type on deforestation in the Brazilian Legal Amazon using remote sensing data

Summary The Brazilian Legal Amazon contains important reservoirs of forest that are threatened by stakeholders’ behaviour. The Cadastro Ambiental Rural (CAR; Rural Environmental Registry) database was used to define the limits and classes of landowner according to private property size. For each class, we identified the annual forest-cover/cover-loss profile at 2-year intervals from 2000 to 2020 based on Brazilian Annual Land Use and Land Cover Mapping Project (MapBiomas) and Program for Deforestation Monitoring (PRODES) data. The analysis revealed that very large landowners dominate the CAR-registered area and that deforestation is influenced by landowner type. The cumulative contributions to deforestation were 2 916 245.96, 1 234 216.79, 2 871 400.36, 2 805 058.62 and 2 637 485.60 ha for very large landowners, large landowners, medium landowners, small landowners and very small landowners, respectively. Very large landowners (1.7% of the total number of properties) had more forest on their properties but caused the greatest amount of deforestation in total, often associated with agribusiness. Small and very small landowners were more numerous (21.0% and 68.3% of the total number of properties, respectively), but they owned a small total area and contributed less to total deforestation. Property size and landownership asymmetry should be considered in deforestation control policies and commitments to the Sustainable Development Goals agenda.

期刊介绍： Environmental Conservation is one of the longest-standing, most highly-cited of the interdisciplinary environmental science journals. It includes research papers, reports, comments, subject reviews, and book reviews addressing environmental policy, practice, and natural and social science of environmental concern at the global level, informed by rigorous local level case studies. The journal"s scope is very broad, including issues in human institutions, ecosystem change, resource utilisation, terrestrial biomes, aquatic systems, and coastal and land use management. Environmental Conservation is essential reading for all environmentalists, managers, consultants, agency workers and scientists wishing to keep abreast of current developments in environmental science.
