重叠的土地用途分配，即一块土地有意或无意地被分配两次或多次用于不同用途，在全球范围内很常见。我们使用秘鲁政府的亚马逊低地数据评估重叠的土地利用分配如何影响森林覆盖变化。结果基于倾向得分匹配双重差分法，使用 2000-2014 年 1 公顷分辨率的森林损失数据以及秘鲁政府土地利用分配数据。我们发现，重叠地区的森林砍伐率低于同类型、非重叠地区的森林砍伐率。这一发现在所有类型的重叠土地利用分配中都是一致的。这些结果支持了多重用途管理减少森林砍伐的假设，并且没有提供任何证据表明重叠分配是一种可能增加森林砍伐的权属不安全形式。我们的研究结果为与多重用途管理、土地保有权安全和避免冲突相关的保护政策提供了信息。
Overlapping land use allocations, in which one parcel of land is allocated two or more times for different uses, either intentionally or unintentionally, are common globally. We assess how overlapping land use allocations impact forest cover change using Peruvian government data for the lowland Amazon. Results are based on propensity score matched difference-in-differences methods using 1-ha resolution forest loss data for 2000-2014, along with Peruvian government land use allocation data. We find that deforestation is lower in overlapping than in same-type, non-overlapping allocations. This finding is consistent across all types of overlapping land use allocations. These results support the hypothesis that multiple use management decreases deforestation, and provide no evidence indicating that overlapping allocations are a form of tenure insecurity that might increase deforestation. Our findings inform conservation policy related to multiple use management, land tenure security, and conflict avoidance.
