Abstract Considerable proportions of the remaining global forest areas are currently harboured in tropical countries. Reducing deforestation in this region is important to help mitigate climate change. Effective forest conservation approach is needed to reduce deforestation and degradation in these countries. Here, we investigated the forest conservation effect of community forests and protected areas using country scale data in Cambodia. In addition to these two forest conservation approaches, we also evaluated the effectiveness of protected forests, which are similar to protected areas but managed by different authorities. We compared deforestation between 2006 and 2016 in areas under the three forest conservation approaches and a non-conserved area by applying the inverse probability of treatment weighting with the propensity score minimizing confounding effects. The results showed that community forest, protected areas, and protected forest significantly decreased deforestation compared with non-conserved forests. Out of the three forest conservation approaches, protected forest was the most effective and community forest was the least effective. We conclude that all of the policies we evaluated are effective for forest conservation but the effectiveness varies depending on the approach. Our findings also suggest that the authority managing the given approach plays an important part in its effectiveness.

一项国家规模分析揭示了影响柬埔寨森林覆盖变化的有效森林政策

摘要 目前,全球剩余的森林面积中有相当大的比例位于热带国家。减少该地区的森林砍伐对于帮助缓解气候变化非常重要。需要有效的森林保护方法来减少这些国家的森林砍伐和退化。在这里,我们使用柬埔寨的国家尺度数据调查了社区森林和保护区的森林保护效果。除了这两种森林保护方法外,我们还评估了受保护森林的有效性,这些森林类似于保护区,但由不同的部门管理。我们通过应用处理加权的逆概率和最小化混杂效应的倾向评分,比较了 2006 年至 2016 年在三种森林保护方法下的区域和非保护区域的森林砍伐。结果表明,与非保护林相比,社区森林、保护区和保护林显着减少了森林砍伐。在三种森林保护方法中,受保护的森林是最有效的,而社区森林的效果最差。我们得出结论,我们评估的所有政策对森林保护都是有效的,但有效性因方法而异。我们的研究结果还表明,管理给定方法的权威对其有效性起着重要作用。保护区和受保护森林与非保护森林相比,森林砍伐显着减少。在三种森林保护方法中,受保护的森林是最有效的,而社区森林的效果最差。我们得出结论,我们评估的所有政策对森林保护都是有效的,但有效性因方法而异。我们的研究结果还表明,管理给定方法的权威对其有效性起着重要作用。保护区和受保护森林与非保护森林相比,森林砍伐显着减少。在三种森林保护方法中,受保护的森林是最有效的,而社区森林的效果最差。我们得出结论,我们评估的所有政策对森林保护都是有效的,但有效性因方法而异。我们的研究结果还表明,管理给定方法的权威对其有效性起着重要作用。我们得出结论,我们评估的所有政策对森林保护都是有效的,但有效性因方法而异。我们的研究结果还表明,管理给定方法的权威对其有效性起着重要作用。我们得出结论,我们评估的所有政策对森林保护都是有效的,但有效性因方法而异。我们的研究结果还表明,管理给定方法的权威对其有效性起着重要作用。
