由于地球表面的大部分地区已经受到人类的严重影响，因此有必要了解需要在哪里进行恢复以实现全球保护目标。在这里，我们表明，至少有190万平方公里的土地，跨越190个（27%）陆地生态区和114个国家，需要恢复，以实现目前的17%的全球保护区目标（爱知目标11）。针对轻度改造土地的恢复可以弥补高达三分之二的缺口，这将对农业产生每年至少2.05亿美元的机会成本影响（平均为159美元/平方公里）。然而，64个（9%）生态区，主要位于东南亚，将需要恢复已经严重修改的地区的具有挑战性的任务。这些结果突出表明，全球保护战略需要认识到许多生态区目前的人为退化水平，并在更大的保护区目标与更具体的恢复目标之间取得平衡。
With much of Earth's surface already heavily impacted by humans, there is a need to understand where restoration is required to achieve global conservation goals. Here, we show that at least 1.9 million km2 of land, spanning 190 (27%) terrestrial ecoregions and 114 countries, needs restoration to achieve the current 17% global protected area target (Aichi Target 11). Restoration targeted on lightly modified land could recover up to two‐thirds of the shortfall, which would have an opportunity cost impact on agriculture of at least $205 million per annum (average of $159/km2). However, 64 (9%) ecoregions, located predominately in Southeast Asia, will require the challenging task of restoring areas that are already heavily modified. These results highlight the need for global conservation strategies to recognize the current level of anthropogenic degradation across many ecoregions and balance bigger protected area targets with more specific restoration goals.
