了解经济作物扩张对天然林的影响至关重要。然而，对于大多数作物来说，没有遥感全球地图，全球森林砍伐影响是使用模型和外推法来估计的。天然橡胶是森林砍伐影响高度不确定的主要商品的一个例子，估计值相差五倍以上。在这里，我们利用地球观测卫星数据和云计算来制作东南亚的高分辨率橡胶地图（10 米像素大小）和相关的森林砍伐（30 米像素大小）。我们的地图表明，政策、公众和最近的报告都大大低估了与橡胶相关的森林损失。我们的直接遥感观测表明，为橡胶而砍伐森林的情况比目前广泛用于制定政策的数据所显示的数字至少高出两到三倍。自 1993 年以来，已有超过 400 万公顷的森林因橡胶而消失（自 2000 年以来至少有 200 万公顷），并且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可能是广泛的。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立法中得到更多关注。用于生成整个东南亚高分辨率地图的卫星数据显示，与橡胶相关的森林砍伐至少比制定政策所估计的高出两到三倍。
Understanding the effects 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 principal commodity for which deforestation impacts have been highly uncertain, with estimates differing more than fivefold. Here we harnessed Earth observation satellite data and cloud computing to produce high-resolution maps of rubber (10 m pixel size) and associated deforestation (30 m pixel size) for Southeast Asia. Our maps indicate that rubber-related forest loss has been substantially underestimated in policy, by the public and in recent reports. Our direct remotely sensed observations show that deforestation for rubber is at least twofold to threefold higher than suggested by figures now widely used for setting policy. With more than 4 million hectares of forest loss for rubber since 1993 (at least 2 million hectares since 2000) and more than 1 million hectares of rubber plantations established in Key Biodiversity Areas, the effects of rubber on biodiversity and ecosystem services in Southeast Asia could be extensive. Thus, rubber deserves more attention in domestic policy, within trade agreements and in incoming due-diligence legislation. Satellite data used to generate high-resolution maps across Southeast Asia show that rubber-related deforestation is at least twofold to threefold higher than suggested by estimates used for setting policy.
