《生物多样性公约》设定的2020年全球保护区空间目标已基本实现，但管理效率仍然不足。人员短缺被广泛认为是主要原因，但以前没有量化。利用来自176个国家和地区的数据，我们估计目前全世界陆地保护区最多有555，000人（每37公里（2）一人），其中包括286，000名护林员（每72公里（2）一人），远远低于所需密度的出版指南。到2030年将保护区的覆盖率扩大到30%，并采取其他有效的区域保护措施，这是保护生物多样性和生态系统服务的最低要求。我们预计，有效管理这一扩大的系统将需要大约300万人（每13公里2人），包括150多万名护林员或同等人员（每26公里2人）。要进行有效、公平和可持续的管理，就必须同时改善资源、工作条件和能力，但在实现保护区的全球空间目标时，管理质量却没有得到相应的提高。这项研究量化了目前这些地区护林员和其他人员的短缺情况，并评估了随着更多地区被留出而未来的需求。
The 2020 global spatial targets for protected areas set by the Convention on Biological Diversity have almost been achieved, but management effectiveness remains deficient. Personnel shortages are widely cited as major contributing factors but have not previously been quantified. Using data from 176 countries and territories, we estimate a current maximum of 555,000 terrestrial protected area personnel worldwide (one per 37 km(2)), including 286,000 rangers (one per 72 km(2)), far short of published guidance on required densities. Expansion by 2030 to 30% coverage of protected areas and other effective area-based conservation measures is widely agreed as a minimum for safeguarding biodiversity and ecosystem services. We project that effective management of this expanded system will require approximately 3 million personnel (one per 13 km(2)), including more than 1.5 million rangers or equivalents (one per 26 km(2)). Parallel improvements in resourcing, working conditions and capacity are required for effective, equitable and sustainable management.Achievement of global spatial targets for protected areas is not being matched by quality of management. This study quantifies current shortfalls in numbers of rangers and other personnel for those areas and assesses future requirements as more areas are set aside.
