了解经济作物扩大对天然林的影响至关重要。然而，对于大多数作物，没有遥感全球地图，全球毁林影响是使用模型和外推法估计的。天然橡胶是毁林影响高度不确定的主要商品的一个例子，估计数相差五倍以上。在这里，我们利用地球观测卫星数据和云计算制作了第一张覆盖整个东南亚的橡胶和相关森林砍伐的高分辨率地图。我们的地图表明，与橡胶有关的森林损失在政策、公众和最近的报告中被大大低估了。我们的直接遥感观测表明，橡胶砍伐量比目前广泛用于制定政策的数字高出两到三倍。自1993年以来，超过376万公顷的森林因橡胶而消失（自2000年以来为277万公顷[2.5-3 95% CI]），在关键生物多样性地区建立了超过100万公顷的橡胶种植园，橡胶对东南亚生物多样性和生态系统服务的影响是广泛的。因此，橡胶值得在国内政策、贸易协定和即将出台的尽职调查条例中得到更多关注。
Understanding the impacts of cash crop expansion on natural forest is of fundamental importance. However, for most crops there are no remotely-sensed global maps, and global deforestation impacts are estimated using models and extrapolations. Natural rubber is an example of a major commodity for which deforestation impacts have been highly uncertain, with estimates differing more than five-fold–. Here we harnessed earth observation satellite data and cloud computing to produce the first high-resolution maps of rubber and associated deforestation covering all Southeast Asia. Our maps indicate that rubber-related forest loss has been significantly underestimated in policy, by the public and in recent reports–. Our direct remotely-sensed observations show that deforestation for rubber is two to threefold higher than suggested by figures currently widely used for setting policy. With over 3.76 million hectares of forest loss for rubber since 1993 (2.77 [2.5-3 95% CI] million hectares since 2000), and over 1 million hectares of rubber plantations established in Key Biodiversity Areas, the impacts of rubber on biodiversity and ecosystem services in Southeast Asia are extensive. Thus, rubber deserves more attention in domestic policy, within trade agreements and in incoming due diligence regulations.
