摘要

墨西哥的蓝碳项目或潮汐湿地(如红树林)的保护和恢复可减少碳排放,同时为当地社区提供额外的生态系统服务。然而,在全国范围内,由于近期森林砍伐速度放缓,红树林项目的 "额外性"(或附加项目效益)难以体现。虽然墨西哥的森林砍伐速度放缓,但红树林退化却普遍存在并不断蔓延。扭转或终止红树林退化可迅速保护储存的碳,减少未来温室气体排放。在此,我们探讨了墨西哥在应对红树林退化和实现成功恢复成果方面所面临的概念、方法和社会挑战。我们发现,第一个挑战是建立一个全国公认的红树林退化定义,该定义应与早期的方法相兼容,并可通过空间成像技术进行测量。其他挑战还包括:使实地监测与遥感退化评估相一致,包括参考地点,使国家项目与全球数据集相一致,以及使信息标准化以满足蓝碳项目的认证要求。最后,知识共享、合作以及报告失败和成功的项目对于快速推进可靠、可验证的蓝碳项目至关重要,这些项目将有效促进墨西哥红树林退化趋势的扭转。

The role of blue carbon in reversing mangrove degradation trends in Mexico

Blue carbon projects in Mexico, or the conservation and restoration of tidal wetlands such as mangroves, can reduce carbon emissions while providing additional ecosystem services for local communities. However, at the national scale, the “additionality” (or added project benefits) of mangrove projects is difficult to demonstrate due to recent slowing deforestation rates. While deforestation in Mexico decelerates, mangrove degradation is pervasive and spreading. Reversing or ending mangrove degradation could rapidly protect the carbon stored and reduce future greenhouse gas emissions. Here, we explore Mexico's conceptual, methodological, and social challenges for tackling mangrove degradation and achieving successful rehabilitation outcomes. We identified that the first challenge is establishing an accepted national definition of mangrove degradation compatible with earlier methods and measurable with spatial imaging techniques. Other challenges are aligning on-ground monitoring with remotely sensed degradation assessments, including reference sites, harmonizing national programs with global datasets, and standardizing information to meet blue carbon project accreditation requirements. Finally, knowledge sharing, collaboration, and reporting failed and successful projects are crucial for fast-forwarding reliable and verifiable blue carbon projects that effectively contribute to reversing mangrove degradation trends in Mexico.

期刊介绍: Biological Conservation is an international leading journal in the discipline of conservation biology. The journal publishes articles spanning a diverse range of fields that contribute to the biological, sociological, and economic dimensions of conservation and natural resource management. The primary aim of Biological Conservation is the publication of high-quality papers that advance the science and practice of conservation, or which demonstrate the application of conservation principles for natural resource management and policy. Therefore it will be of interest to a broad international readership.
