Abstract

“Tapajós” narrates the field campaign of two researchers studying forest fragmentation in the Brazilian Amazon. It addresses a contemporary conflict in the region, where an Indigenous people, the Munduruku, are resisting efforts by the Brazilian State to channelize the Tapajós River and exploit its hydropower potential. Development here represents an existential threat to the Munduruku, whose homeland resides in the river valley. It also represents an ecological threat to the global community. Although the rate of deforestation dropped after the turn of the millennium, it has begun to climb again and would no doubt accelerate with development in the Tapajós watershed and the opening of Central Amazonia to colonization and resource extraction. This would push the forest past its tipping point, a magnitude of deforestation capable of compromising rainfall recycling, and thus precipitating the transformation of the Amazonian forest into a patchwork of fireadapted shrubs and grasses. “Tapajós” describes how such an ecological catastrophe would occur. It also argues that the assertion of Indigenous territorial rights is key to the conservation of Amazonian biodiversity. The account unfolds against a background of conflict between Amazonia’s Indigenous peoples and the Brazilian State. In so doing, it brings to life the realities of frontier violence involving both land conflict and the unrestrained behaviors of individuals living outside the institutional constraints of law. Such violence complicates the execution of field research in the region and contributes to its gathering ecological crisis.
“Tapajós”讲述了两位研究人员在巴西亚马逊地区研究森林破碎化的实地活动。它解决了该地区当前的一场冲突,在那里,土著人民蒙杜鲁库人正在抵制巴西国家为Tapajós河开凿水道和开发其水电潜力所作的努力。这里的发展对蒙杜鲁库人的生存构成了威胁,他们的家园居住在河谷中。它也对全球社会构成了生态威胁。虽然森林砍伐率在千禧年之后下降了,但它又开始攀升,毫无疑问,随着Tapajós流域的发展和中亚马逊地区向殖民化和资源开采的开放,它将加速。这将使森林越过它的临界点,大规模的森林砍伐可能会影响降雨的循环,从而加速亚马逊森林的转变,变成一个由适应火灾的灌木和草组成的拼凑物。“Tapajós”描述了这样的生态灾难是如何发生的。它还认为,土著领土权利的主张是保护亚马逊生物多样性的关键。故事以亚马逊土著人和巴西政府之间的冲突为背景展开。在这样做的过程中,它使涉及土地冲突和生活在法律制度约束之外的个人不受约束的行为的边境暴力的现实栩栩如生。这种暴力使该地区实地研究的执行复杂化,并助长了其日益严重的生态危机。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
