摘要

棕榈油 (PO) 生产国正在扩大油棕种植面积,以满足日益增长的需求,但却牺牲了热带森林及其提供的生态系统服务 (ES)。对于日益高涨的可持续棕榈油贸易的呼声,目前的应对措施主要基于对环境的影响,如砍伐森林,部分原因是大多数社会影响尚未得到研究。这些应对措施以亚洲和南美洲的信息为基础,因为非洲的研究很少。本研究通过综合同行评审和灰色文献中有关 PO 贸易对 ES 的影响,填补了这些空白。我们的案例研究对象是喀麦隆,该国拥有刚果盆地的部分森林,森林砍伐速度很快。本研究使用了 53 种文献来源(53% 为同行评审文献,47% 为灰色文献)。我们发现,油棕种植对 15 种生态系统服务产生负面影响的有 147 例(85%),对 7 种生态系统服务产生正面影响的有 25 例(15%)。大部分负面影响涉及碳固存和气候调节(20%)、栖息地质量(13%)和遗传多样性(13%)。最积极的影响是对粮食供应的影响(8%)。这些结果凸显了粮食供应与其他环境服务之间的权衡。虽然当前的政策应对措施侧重于环境影响,但许多负面社会影响与 PO 贸易有关,应在新的政策工具中加以解决。

Impacts of palm oil trade on ecosystem services: Cameroon as a case study
Palm oil (PO) producing countries are expanding oil palm cultivated areas to meet growing demands at the expense of tropical forests and the ecosystem services (ES) they provide. Current responses to the growing call for sustainable PO trade are based on environmental impacts such as deforestation, partly because most social impacts have not been studied. These responses are based on information from Asia and South America since little has been done in Africa. This study fills these gaps by synthesizing the impacts of PO trade on ES from peer-reviewed and gray literature. Our case study is Cameroon, which harbors part of the Congo basin forest and experiences fast deforestation rates. Fifty-three sources of literature were used for this study (53% peer-reviewed and 47% gray literature). We found that oil palm cultivation was reported to negatively affect 15 ecosystem services in 147 instances (85%) and positively affect seven ecosystem services in 25 instances (15%). The majority of negative impacts were on carbon sequestration and climate regulation (20%), habitat quality (13%) and genetic diversity (13%). The most positive impact was on food provision (8%). These results highlight the trade-offs between food provision and other ES. While current policy responses have focused on environmental impacts, many negative social impacts are associated with PO trade that should be addressed within new policy tools.
