摘要

撒哈拉以南非洲(SSA)标志性的生物多样性具有巨大的潜在全球价值,但正受到日益增加的人为压力的危害。富裕国家消费的增加和国际公司的需求表现在对SSA的大量资源开采。SSA的生物多样性也面临着越来越大的国内压力,包括人口的快速增长。人口结构向低生育率的转变在SSA比其他地方发生得更晚、更慢,到2100年,该大陆的人口可能会翻两番。因此,SSA的生物多样性将经历一个人为压力不断增加的瓶颈,同时也将经历气候变化的加剧影响。在未来几十年里,SSA的生物多样性可能会严重减少,许多物种将濒临灭绝。然而,从长远来看,南南亚地区的自然保护前景应该会有所改善,我们预测该地区最终将进入绿色人类世。在这里,我们概述了将SSA的生物多样性带入绿色人类世时代所需的关键步骤。

Shepherding Sub-Saharan Africa's Wildlife Through Peak Anthropogenic Pressure Toward a Green Anthropocene
Sub-Saharan Africa's (SSA's) iconic biodiversity is of immense potential global value but is jeopardized by increasing anthropogenic pressures. Elevated consumption in wealthier countries and the demands of international corporations manifest in significant resource extraction from SSA. Biodiversity in SSA also faces increasing domestic pressures, including rapidly growing human populations. The demographic transition to lower fertility rates is occurring later and slower in SSA than elsewhere, and the continent's human population may quadruple by 2100. SSA's biodiversity will therefore pass through a bottleneck of growing anthropogenic pressures, while also experiencing intensifying effects of climate change. SSA's biodiversity could be severely diminished over the coming decades and numerous species pushed to extinction. However, the prospects for nature conservation in SSA should improve in the long term, and we predict that the region will eventually enter a Green Anthropocene. Here, we outline critical steps needed to shepherd SSA's biodiversity into the Green Anthropocene epoch.

期刊介绍: The Annual Review of Environment and Resources, established in 1976, offers authoritative reviews on key environmental science and engineering topics. It covers various subjects, including ecology, conservation science, water and energy resources, atmosphere, oceans, climate change, agriculture, living resources, and the human dimensions of resource use and global change. The journal's recent transition from gated to open access through Annual Reviews' Subscribe to Open program, with all articles published under a CC BY license, enhances the dissemination of knowledge in the field.
