Coral Reef Threats - Reefs at Risk

Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).

Like the original Reefs at Risk, this study evaluates threats to coral reefs from a wide range of human activities. For the first time, it also includes an assessment of climate-related threats to reefs. In addition, Reefs at Risk Revisited includes a global assessment of the vulnerability of nations and territories to coral reef degradation, based on their dependence on coral reefs and their capacity to adapt.

WRI led the Reefs at Risk Revisited analysis in collaboration with a broad partnership of more than 25 research, conservation, and educational organizations. Partners have provided data, offered guidance on the analytical approach, contributed to the report, and served as critical reviewers of the maps and findings.

Reefs at Risk Revisited is a project of the World Resources Institute (WRI), developed and implemented in close collaboration with:
The Nature Conservancy (TNC)
WorldFish Center
International Coral Reef Action Network (ICRAN)
United Nations Environment Programme - World Conservation Monitoring Centre (UNEP-WCMC)
Global Coral Reef Monitoring Network (GCRMN)

《重返风险海域》是一项针对原始全球分析《风险海域：世界珊瑚礁威胁的地图指标》的高分辨率更新。该研究采用500米分辨率的全球珊瑚礁地图，其细节程度是1998年分析中使用的4公里分辨率地图的64倍，并得益于许多全球数据集的改进，这些数据集被用于评估对珊瑚礁的威胁（大多数威胁数据为1公里分辨率，其细节程度是1998年分析中使用的16倍）。与原始《风险海域》相似，本研究从广泛的人类活动角度评估了对珊瑚礁的威胁。首次，它还纳入了对珊瑚礁气候相关威胁的评估。此外，《重返风险海域》还包括了对各国和地区对珊瑚礁退化脆弱性的全球评估，该评估基于其对珊瑚礁的依赖程度及其适应能力。

世界资源研究所（WRI）主导了《重返风险海域》的分析工作，并与超过25个研究、保护和教育组织广泛合作。合作伙伴提供了数据，提供了分析方法的指导，为报告做出了贡献，并作为地图和发现的重要审稿人。

《重返风险海域》是世界资源研究所（WRI）的项目，与以下机构紧密合作开发和实施：

自然保护协会（TNC）、世界渔业中心、国际珊瑚礁行动网络（ICRAN）、联合国环境规划署-世界保护监测中心（UNEP-WCMC）、全球珊瑚礁监测网络（GCRMN）。

许多其他政府机构、国际组织、研究机构、大学、非政府组织和倡议提供了科学指导、贡献数据并审查结果，包括：大西洋和墨西哥湾快速珊瑚礁评估（AGRRA）、印度洋沿海海洋研究与开发（CORDIO）、国际保护组织（CI）、珊瑚礁联盟（CORAL）、健康珊瑚礁与健康人类、国际珊瑚礁研究学会（ISRS）、国际自然保护联盟（IUCN）、法国发展研究研究所（IRD）、生态分析与综合国家中心（NCEAS）、海洋组织（Oceana）、行星珊瑚礁基金会、项目AWARE基金会、珊瑚礁检查、珊瑚礁环境教育基金会（REEF）、海网、太平洋社区秘书处（SPC）、太平洋区域环境规划秘书处（SPREP）、美国国家航空航天局（NASA）、美国国家海洋和大气管理局（NOAA）、南佛罗里达大学（USF）、南太平洋大学（USP）、野生动物保护协会（WCS）、世界自然基金会（WWF）。
