Globally, deforestation continues, and although protected areas effectively protect forests, the majority of forests are not in protected areas. Thus, how effective are different management regimes to avoid deforestation in non-protected forests? We sought to assess the effectiveness of different national forest-management regimes to safeguard forests outside protected areas. We compared 2000-2014 deforestation rates across the temperate forests of 5 countries in the Himalaya (Bhutan, Nepal, China, India, and Myanmar) of which 13% are protected. We reviewed the literature to characterize forest management regimes in each country and conducted a quasi-experimental analysis to measure differences in deforestation of unprotected forests among countries and states in India. Countries varied in both overarching forest-management goals and specific tenure arrangements and policies for unprotected forests, from policies emphasizing economic development to those focused on forest conservation. Deforestation rates differed up to 1.4% between countries, even after accounting for local determinants of deforestation, such as human population density, market access, and topography. The highest deforestation rates were associated with forest policies aimed at maximizing profits and unstable tenure regimes. Deforestation in national forest-management regimes that emphasized conservation and community management were relatively low. In India results were consistent with the national-level results. We interpreted our results in the context of the broader literature on decentralized, community-based natural resource management, and our findings emphasize that the type and quality of community-based forestry programs and the degree to which they are oriented toward sustainable use rather than economic development are important for forest protection. Our cross-national results are consistent with results from site- and regional-scale studies that show forest-management regimes that ensure stable land tenure and integrate local-livelihood benefits with forest conservation result in the best forest outcomes.
在全球范围内,森林砍伐仍在继续,尽管保护区有效地保护了森林,但大多数森林并不在保护区内。那么,不同的管理体制在避免非保护区森林砍伐方面的效果如何呢?我们试图评估不同国家森林管理体制在保护保护区外森林方面的有效性。我们比较了喜马拉雅地区5个国家(不丹、尼泊尔、中国、印度和缅甸)温带森林在2000年至2014年期间的森林砍伐率,其中13%的森林受到保护。我们查阅了文献以描述每个国家的森林管理体制,并进行了准实验分析,以衡量印度各国和各邦未受保护森林的砍伐差异。各国在总体森林管理目标以及未受保护森林的具体权属安排和政策方面存在差异,从强调经济发展的政策到专注于森林保护的政策各不相同。即使在考虑了森林砍伐的当地决定因素,如人口密度、市场准入和地形之后,各国之间的森林砍伐率差异仍高达1.4%。最高的森林砍伐率与旨在实现利润最大化的森林政策和不稳定的权属制度相关。强调保护和社区管理的国家森林管理体制中的森林砍伐率相对较低。在印度,结果与国家层面的结果一致。我们在关于分散的、基于社区的自然资源管理的更广泛文献背景下解读了我们的结果,我们的研究结果强调,基于社区的林业项目的类型和质量以及它们面向可持续利用而非经济发展的程度对于森林保护很重要。我们的跨国研究结果与实地和区域尺度研究的结果一致,这些研究表明,确保稳定土地权属并将当地生计利益与森林保护相结合的森林管理体制会带来最佳的森林保护成果。
