实现森林的可持续性是一项已宣布的可持续发展目标（SDG 15）。衡量全球森林的安全运作空间-地球边界-对于确定全球森林压力和可持续地管理森林至关重要。在这里，我们量化了森林的地球边界（FPB）和国家森林边界。结果表明，2015年，FPB为71亿m3森林蓄积增量。全球木材收获量占FPB的58.7%。47个国家的木材收获量已超过其国家森林边界，其中大部分在非洲和亚洲。它们的越界采伐主要是受发达国家最终需求的驱动（例如，美国和日本）和新兴经济体（例如，印度和中国）通过全球供应链。这项研究强调了FPB在全球森林管理和贸易相关决策中的重要性。这些发现可以指导全球和国家的森林采伐活动，并有助于促进国际合作，以减轻全球森林砍伐。
Achieving forest sustainability is a declared sustainable development goal (SDG 15). Measuring the safe operating space─planetary boundaries─of global forests is essential to determine global forest pressure and manage forests sustainably. Here, we quantify the forestry planetary boundary (FPB) and national forestry boundaries. Results show that, in 2015, the FPB was 7.1 billion m3of forest stock increments. Global timber harvests account for 58.7% of the FPB. Timber harvests of 47 nations, mostly in Africa and Asia, have exceeded their national forestry boundaries. Their boundary-exceeding timber harvest is mainly driven by the final demand of developed nations (e.g., the United States and Japan) and emerging economies (e.g., India and China) through global supply chains. This study highlights the importance of the FPB in global forest management and trade-related policymaking. The findings can guide global and national forest harvesting activities and help promote international cooperation to mitigate global deforestation.
