SummaryProtecting tropical forests from deforestation is important for mitigating both biodiversity loss and anthropogenic climate change. In Amazonia, a common approach to protected area (PA) impact studies has been to investigate differences among broad PA categories, such as strictly protected, sustainable use and indigenous areas, yet these may be insufficient for the management of PAs at local scales. We used a matching method to compare impacts and carbon emissions avoided during 2011–2016 of individual PAs in the state of Acre (Brazil). Although most PAs had a positive impact and effectively prevented forest loss, we observed substantial variation among them in terms of impacts, pressures and emissions during our study period. The impacts varied from 3.6% avoided to 15.6% induced forest loss compared to expected levels of deforestation estimated for each PA using the matching method. All but a few PAs helped avoid substantial amounts of emissions. Our results emphasize the need for more PA impact studies that compare multiple PAs at the individual level in Amazonia and beyond.

个别保护区对巴西阿克里地区森林砍伐和碳排放的影响

摘要保护热带森林免受森林砍伐对于减轻生物多样性丧失和人为气候变化都很重要。在亚马逊流域，保护区 (PA) 影响研究的一种常见方法是调查广泛的保护区类别之间的差异，例如严格保护、可持续利用和土著地区，但这些可能不足以在当地范围内管理保护区。我们使用匹配方法比较了 2011-2016 年期间 Acre 州（巴西）各个保护区的影响和避免的碳排放。尽管大多数保护区都产生了积极影响并有效地防止了森林损失，但在我们的研究期间，我们观察到它们在影响、压力和排放方面存在很大差异。影响从避免的 3.6% 到 15% 不等。与使用匹配方法估计的每个 PA 的预期森林砍伐水平相比，造成 6% 的森林损失。除少数几个保护区外，所有保护区都有助于避免大量排放。我们的结果强调需要进行更多的 PA 影响研究，以比较亚马逊及其他地区个人层面的多个 PA。
