The depletion of forests in conservation hotspots is a poorly known societal concern of the post‐conflict society of Angola. Rapid economic and population growth, fragile environmental regulation, enforcement, and planning threat these invaluable forests and their biodiversity. By mitigating climate change through a sustainable management of forests, Reducing Emissions from Deforestation and forest Degradation (REDD+) could also favour the preservation of biodiversity. This study addresses the depletion of forests in Angolan conservation ‘hotspots’ under a REDD+ perspective. In the escarpment forest, a centre of endemism, activity data, and emission factors were assessed between 2001 and 2014. Next, spatial factors associated with deforestation were identified using generalized linear modelling, and it was provided a view on how REDD+ may support sustainable forest management in conservation hotspots. Activity data based on an error‐corrected estimate indicated a deforested area of 4856.3 ± 653.1 ha between 2001 and 2014. Field mean above‐ground carbon content amounted to 89.4 ± 126.4 tCha‐1. Among the most relevant factors associated with deforestation were elevation, density of bare land, north–south exposure (aspect), and distance to trails. All negatively related to deforestation. Overall, the threatened escarpment forest conservation hotspot seems to have significant potential for reducing carbon emissions and beneficiate from REDD+. Yet the considerable uncertainty in our estimates limited the discussions in the magnitude of forest depletion and carbon emissions. In view of performance‐based payments for development, additional field surveying is necessary to boost the accuracies presented by new forest monitoring tools that can reduce technical difficulties and sustain the eligibility of Angola for international REDD+ funding sources.

减少安哥拉森林砍伐和森林退化 (REDD+) 的排放:来自悬崖森林保护热点的见解

保护热点中森林的枯竭是安哥拉冲突后社会鲜为人知的社会问题。快速的经济和人口增长、脆弱的环境监管、执法和规划威胁着这些宝贵的森林及其生物多样性。通过可持续管理森林来缓解气候变化,减少森林砍伐和森林退化所致排放量 (REDD+) 也有利于保护生物多样性。本研究从 REDD+ 的角度解决了安哥拉保护“热点”中森林的枯竭问题。在悬崖林中,2001 年至 2014 年间评估了一个特有现象、活动数据和排放因子的中心。接下来,使用广义线性模型确定了与森林砍伐相关的空间因子,并提供了关于 REDD+ 如何支持保护热点地区的可持续森林管理的观点。基于误差校正估计的活动数据表明,2001 年至 2014 年间森林砍伐面积为 4856.3 ± 653.1 公顷。实地平均地上碳含量为 89.4 ± 126.4 tCha-1。与森林砍伐最相关的因素包括海拔、裸地密度、南北暴露(方面)和到小径的距离。所有这些都与森林砍伐呈负相关。总体而言,受威胁的悬崖森林保护热点似乎具有减少碳排放的巨大潜力,并受益于 REDD+。然而,我们估计中相当大的不确定性限制了对森林枯竭和碳排放量的讨论。鉴于以绩效为基础的发展付款,
