珊瑚礁可以为人民和财产提供重大的沿海保护利益。在这里，我们表明，如果没有珊瑚礁，洪水造成的年度预期损失将增加一倍，频繁风暴造成的损失将增加两倍。对于100年一遇的风暴事件，如果没有珊瑚礁，洪水损失将增加91%，达到2720亿美元。从珊瑚礁管理中获益最多的国家是印度尼西亚、菲律宾、马来西亚、墨西哥和古巴;这些国家每年预计节省的洪水费用超过4亿美元。海平面上升将增加洪水风险，但如果没有更好的近期管理，珊瑚礁损失本身就可能产生重大影响。我们在（次）国家一级对整个海洋生物群落的生态系统服务进行全球性的、基于过程的评估。这些明确的空间效益为关键风险和环境管理决策提供了信息，政府可以直接考虑预期效益（例如，国民账户、恢复计划）和企业（例如，保险）。
Coral reefs can provide significant coastal protection benefits to people and property. Here we show that the annual expected damages from flooding would double, and costs from frequent storms would triple without reefs. For 100-year storm events, flood damages would increase by 91% to $US 272 billion without reefs. The countries with the most to gain from reef management are Indonesia, Philippines, Malaysia, Mexico, and Cuba; annual expected flood savings exceed $400 M for each of these nations. Sea-level rise will increase flood risk, but substantial impacts could happen from reef loss alone without better near-term management. We provide a global, process-based valuation of an ecosystem service across an entire marine biome at (sub) national levels. These spatially explicit benefits inform critical risk and environmental management decisions, and the expected benefits can be directly considered by governments (e.g., national accounts, recovery plans) and businesses (e.g., insurance).
