2019年3月1日，联合国大会（纽约）宣布2021-2030年为“联合国生态系统恢复十年”。这一行动呼吁的目的是认识到需要大规模加速全球退化生态系统的恢复，应对气候变暖危机，加强粮食安全，提供清洁水和保护地球上的生物多样性。修复的规模将是关键；例如，波恩挑战的目标是到2030年恢复3.5亿平方公里（几乎相当于印度的面积）退化的陆地生态系统。然而，国际上对恢复“蓝色”沿海生态系统的支持一直滞后，这些生态系统为人们提供了一系列令人印象深刻的好处。只有全球红树林联盟（https://mangrovealliance.org/）接近波恩挑战，其目标是到2030年将全球红树林面积增加20%。然而，红树林科学家对这一目标持保留态度，他们担心这是不现实的，可能会促使人们在试图达到这一目标时采取不适当的做法（Lee et al., 2019）。生态系统恢复十年宣言也与旨在扭转海洋健康恶化的联合国海洋科学促进可持续发展十年相吻合。如果以整体和协调的方式执行，签署国可以履行联合国的这两项行动呼吁。
On 1 March 2019, the United Nations (UN) General Assembly (New York) declared 2021–2030 the "UN Decade on Ecosystem Restoration." This call to action has the purpose of recognizing the need to massively accelerate global restoration of degraded ecosystems, to fight the climate heating crisis, enhance food security, provide clean water and protect biodiversity on the planet. The scale of restoration will be key; for example, the Bonn Challenge has the goal to restore 350 million km2 (almost the size of India) of degraded terrestrial ecosystems by 2030. However, international support for restoration of "blue" coastal ecosystems, which provide an impressive array of benefits to people, has lagged. Only the Global Mangrove Alliance (https://mangrovealliance.org/) comes close to the Bonn Challenge, with the aim of increasing the global area of mangroves by 20% by 2030. However, mangrove scientists have reservations about this target, voicing concerns that it is unrealistic and may prompt inappropriate practices in attempting to reach this target (Lee et al., 2019). The decade of ecosystem restoration declaration also coincides with the UN Decade of Ocean Science for Sustainable Development, which aims to reverse deterioration in ocean health. If executed in a holistic and coordinated manner, signatory nations could stand to deliver on both these UN calls to action.
