2000 年至 2010 年，油棕扩张导致全球森林面积减少 200 万公顷 (Mha)。尽管油棕种植面积占世界总面积的 24%（4.5 Mha），但撒哈拉以南非洲地区的扩张动态却被忽视了。我们发现，在非洲最大的产区喀麦隆西南部，2000 年至 2015 年期间 67% 的油棕扩张是以牺牲森林为代价的。与工业规模扩张的公开说法相反，大多数油棕扩张和相关的森林砍伐都发生在大型农工业特许权之外。非工业生产者进行的扩张和森林砍伐发生在低效率的非正规工厂附近，不受高效率公司自有工厂位置的限制。这些结果凸显了蓬勃发展的非正规经济部门在推动土地利用快速变化方面的关键作用。撒哈拉以南非洲地区的高人均消费量和不断增长的棕榈油需求凸显了在确定区域相关可持续发展路径时考虑非正规经济的必要性。
Oil palm expansion resulted in 2 million hectares (Mha) of forest loss globally in 2000-2010. Despite accounting for 24% (4.5 Mha) of the world's total oil palm cultivated area, expansion dynamics in sub-Saharan Africa have been overlooked. We show that in Southwest Cameroon, a top producing region of Africa, 67% of oil palm expansion from 2000-2015 occurred at the expense of forest. Contrary to the publicized narrative of industrial-scale expansion, most oil palm expansion and associated deforestation is occurring outside large agro-industrial concessions. Expansion and deforestation carried out by non-industrial producers is occurring near low-efficiency informal mills, unconstrained by the location of high efficiency company-owned mills. These results highlight the key role of a booming informal economic sector in driving rapid land use change. High per capita consumption and rising palm oil demands in sub-Saharan Africa spotlight the need to consider informal economies when identifying regionally relevant sustainability pathways.
