SummarySubtropical dry forests are among the largest and most threatened terrestrial biomes worldwide. In Argentina, the Native Forest Law (NFL) was passed in 2007 to regulate deforestation by mandating the provincial zonation of forested areas, while the erection of fences has been an increasingly common mechanism of private-land control reinforcement in the region; this is mainly fuelled by imminent land-use changes, recent land transactions or subsidies from the NFL. We explored the dynamics between the erection of fences and deforestation in the Northern Argentinian Dry Chaco (NADC) during the implementation of the NFL. We found that a third of land deforested during 2000–2017 had been previously fenced, with the highest percentage (44%) occurring during the sanction of the NFL (2007) and the completion of the forest-zonation maps (2011). Only 34% of deforestation within fenced areas occurred in zones where deforestation was legally permitted. In total, 327 386 ha of forests had been fenced within NADC by 2017, representing areas of potential access restriction for local people, who historically used forest resources for survival. Additionally, 57% of the fenced area occurred in zones where deforestation was restricted. A novel remote-sensing application can serve as an early-warning tool for deforestation.

阿根廷北部旱查科地区实施土著森林法背景下的私有土地控制和森林砍伐动态

摘要亚热带干旱森林是世界上最大和最受威胁的陆地生物群落之一。在阿根廷，2007 年通过了《本土森林法》（NFL），通过强制对森林区域进行省级分区来规范森林砍伐，而围栏的架设已成为该地区日益普遍的私有土地控制机制；这主要是由于即将发生的土地使用变化、最近的土地交易或 NFL 的补贴。我们探讨了在 NFL 实施期间在阿根廷北部干查科 (NADC) 竖立围栏和砍伐森林之间的动态。我们发现，在 2000 年至 2017 年期间砍伐森林的土地中有三分之一以前被围起来，其中百分比最高 (44%) 发生在 NFL（2007 年）制裁和森林分区图（2011 年）完成期间。只有 34% 的围栏区域内的森林砍伐发生在法律允许砍伐森林的区域。到 2017 年，NADC 内总共有 327,386 公顷的森林被围起来，这代表了当地人可能进入限制的区域，他们历来使用森林资源谋生。此外，57% 的围栏区域发生在限制森林砍伐的地区。一种新颖的遥感应用可以作为森林砍伐的预警工具。57% 的围栏区域发生在限制森林砍伐的地区。一种新颖的遥感应用可以作为森林砍伐的预警工具。57% 的围栏区域发生在限制森林砍伐的地区。一种新颖的遥感应用可以作为森林砍伐的预警工具。
