摘要

本文从总面积、地区和社区三个尺度探讨了秘鲁亚马逊地区25个土著社区土地(ICLs) 40年来415,749公顷的森林砍伐和再造林动态。我们将icl作为分析的领土单位,因为它们对保护的重要性越来越多地被讨论。此外,土著社区(ic)是亚马逊地区一个过于边缘化的群体,值得更多关注。这类分析通常是短期的,只使用大规模的地球观测方法。我们使用多方法方法将遥感与地面验证联系起来,并将定性的历史政治生态学工作与ic联系起来。我们发现,总体累计毁林率低至5%,但考虑到再造林,净毁林率仅为3.5%。在社区层面,森林砍伐和造林动态是复杂的,除了一个时期表明该地区的宏观国家驱动因素。结果表明,在毁林分析中对森林再生的考虑不足,并挑战了向利益攸关方提供森林累积损失价值在森林和人口动态变化的热带地区有帮助的观念。此外,我们在与社区的合作中强调,将社区及其土地笼统地归类为亲环境或不亲环境,无助于确定ICLs用于环境或发展目的的资金流。

Forty-year multi-scale land cover change and political ecology data reveal a dynamic and regenerative process of forests in Peruvian Indigenous Territories

This article explores deforestation and reforestation dynamics over 415,749 hectares of 25 titled Indigenous Community Lands (ICLs) in the Peruvian Amazon over forty years at three scales: total area, regions, and communities. We focus on ICLs as the territorial unit of analysis, as they are increasingly discussed regarding their importance for conservation. Additionally indigenous communities (ICs) are a too-marginalized group in the Amazon that merit more attention. Analyses of this kind are often short-term and use only large-scale Earth Observation methodologies. We use a multi-method approach linking remote sensing with ground verification, and qualitative historical political ecology work with ICs. We find that overall accumulated deforestation was low at 5%, but that when reforestation is considered, net deforestation was only 3.5%. At the community level deforestation and afforestation dynamics are complex, except for one period that indicates a macro state driver in the region. Results suggest inadequate accounting for forest regeneration in deforestation analyses and challenge the notion that presenting stakeholders with accumulated forest loss values is helpful in tropical areas where forests and people are dynamic. Furthermore, our work with communities highlights that categorizing them and their lands as pro-environment or not in general terms is unhelpful for determining fund flows to ICLs for environmental or development purposes.

期刊介绍: Global Environmental Change is a prestigious international journal that publishes articles of high quality, both theoretically and empirically rigorous. The journal aims to contribute to the understanding of global environmental change from the perspectives of human and policy dimensions. Specifically, it considers global environmental change as the result of processes occurring at the local level, but with wide-ranging impacts on various spatial, temporal, and socio-political scales. In terms of content, the journal seeks articles with a strong social science component. This includes research that examines the societal drivers and consequences of environmental change, as well as social and policy processes that aim to address these challenges. While the journal covers a broad range of topics, including biodiversity and ecosystem services, climate, coasts, food systems, land use and land cover, oceans, urban areas, and water resources, it also welcomes contributions that investigate the drivers, consequences, and management of other areas affected by environmental change. Overall, Global Environmental Change encourages research that deepens our understanding of the complex interactions between human activities and the environment, with the goal of informing policy and decision-making.
