Abstract

Tropical peatlands are a globally important carbon store. They host significant biodiversity and provide a range of other important ecosystem services, including food and medicines for local communities. Tropical peatlands are increasingly modified by humans in the rapid and transformative way typical of the “Anthropocene,” with the most significant human—driven changes to date occurring in Southeast Asia. This review synthesizes the dominant changes observed in human interactions with tropical peatlands in the last 200 years, focusing on the tropical lowland peatlands of Southeast Asia. We identify the beginning of transformative anthropogenic processes in these carbon-rich ecosystems, chart the intensification of these processes in the 20th and early 21st centuries, and assess their impacts on key ecosystem services in the present. Where data exist, we compare the tropical peatlands of Central Africa and Amazonia, which have experienced very different scales of disturbance in the recent past. We explore their global importance and how environmental pressures may affect them in the future. Finally, looking to the future, we identify ongoing efforts in peatland conservation, management, restoration, and socio-economic development, as well as areas of fruitful research toward sustainability of tropical peatlands.

人类世的热带泥炭地:现在与未来
热带泥炭地是全球重要的碳储存库。它们拥有丰富的生物多样性,并提供一系列其他重要的生态系统服务,包括为当地社区提供食品和药品。热带泥炭地越来越多地被人类以“人类世”典型的快速和变革的方式改造,迄今为止人类驱动的最重大变化发生在东南亚。本文综述了近200年来人类与热带泥炭地相互作用的主要变化,重点介绍了东南亚热带低地泥炭地。我们确定了这些富碳生态系统中变革性人为过程的开始,绘制了这些过程在20世纪和21世纪初的强化图,并评估了它们对当前关键生态系统服务的影响。在有数据的地方,我们比较了中非和亚马逊地区的热带泥炭地,它们在最近的过去经历了非常不同规模的扰动。我们将探讨它们在全球的重要性,以及未来环境压力对它们的影响。最后,展望未来,我们确定了泥炭地保护、管理、恢复和社会经济发展方面的持续努力,以及热带泥炭地可持续性研究的成果领域。

期刊介绍: Anthropocene is an interdisciplinary journal that publishes peer-reviewed works addressing the nature, scale, and extent of interactions that people have with Earth processes and systems. The scope of the journal includes the significance of human activities in altering Earth’s landscapes, oceans, the atmosphere, cryosphere, and ecosystems over a range of time and space scales - from global phenomena over geologic eras to single isolated events - including the linkages, couplings, and feedbacks among physical, chemical, and biological components of Earth systems. The journal also addresses how such alterations can have profound effects on, and implications for, human society. As the scale and pace of human interactions with Earth systems have intensified in recent decades, understanding human-induced alterations in the past and present is critical to our ability to anticipate, mitigate, and adapt to changes in the future. The journal aims to provide a venue to focus research findings, discussions, and debates toward advancing predictive understanding of human interactions with Earth systems - one of the grand challenges of our time.
