摘要

中非的刚果盆地是世界上仅次于亚马逊的第二大雨林的所在地。这些森林吸收的碳比任何其他热带森林都要多,无论是在地上的生物量还是在世界上最大的泥炭矿床中。这些生态系统对生物多样性以及当地人民的生计和福祉至关重要,它们在地方、区域和全球水循环中发挥着至关重要的作用。这项对气候变化和生物多样性科学的跨学科分析被用来汇集多种信息来源,以评估气候风险对中非森林和生活在那里的人们的危害、暴露和脆弱性。通过整合多种来源的气候数据和文献综述,开发了量身定制的气候信息。对这些信息进行了分析,同时对刚果盆地森林的生物多样性进行了审查,以便评估森林生态系统功能面临的气候风险。很明显,气候变化的可能影响需要与中非广泛的人为压力一起理解,并根据其相互作用来理解。中非森林的生态系统服务对全球至关重要,但却面临着相互竞争的压力,而且在传统经济条件下被低估了。石油和天然气勘探是对全球气候变化减缓协议和生物多样性的挑战。狩猎已经导致一些地区的退化,扰乱了生态系统并威胁到标志性物种。不受管制的采伐和用于农业和油棕种植园的森林砍伐也是对森林生态和生物多样性的主要威胁。这项研究的联合方法表明,专业知识的整合对于支持气候主流化和满足日益增长的对证据的需求是必要的,这些证据可以为全球生物多样性地区的保护战略提供信息,特别是在中非森林等观测稀疏地区。

Insights on Climate Risks to the Central African Forest Ecosystems: An Interdisciplinary Review

Insights on Climate Risks to the Central African Forest Ecosystems: An Interdisciplinary Review

The Congo Basin in Central Africa is home to the second largest rainforest in the world after the Amazon. These forests sequester more carbon than any other tropical forest both in the above-ground biomass and in the world's largest peat deposits, located in the Cuvette Centrale. These ecosystems are important for biodiversity and the livelihoods and wellbeing of local people, and they play a crucial role in local, regional and global water cycles.

This interdisciplinary analysis of climate change and biodiversity sciences was used to bring together multiple sources of information to assesses the hazard, exposure and vulnerability dimensions of climate risks to Central Africa's forests and the people who live there. Tailored climate information was developed by integrating multiple sources of climate data and literature reviews. This information was analysed alongside a review of biological diversity in the Congo Basin forests so that climate risks to the functioning of forest ecosystems could be assessed. It is clear that the possible impacts of climate change need to be understood alongside and in terms of interactions with a wide range of anthropic pressures in Central Africa.

The ecosystem services of Central Africa's forests are globally essential but face competing pressures and are undervalued in conventional economic terms. Oil and gas exploration is a challenge to global climate change mitigation agreements and to biodiversity. Hunting has led to defaunation in some areas, disturbing ecosystems and threatening iconic species. Unregulated logging and forest clearance for agriculture and oil palm plantations are also major threats to forest ecology and biodiversity.

The joint approach of this study demonstrates that integration of expertise is necessary to support climate mainstreaming and to meet the growing demand for evidence to inform protection strategies for biodiverse regions worldwide, particularly in observation sparse areas such as Central African forests.
