为东非创建了一个沿海变化脆弱性指数，整合了社会脆弱性和沿海灾害暴露指数，以确定减少风险的“优先关注领域”。目前，东非22%的海岸线和350万人面临更高水平的沿海灾害，如果红树林、珊瑚礁和海草消失，这一比例将分别增加到39%和690万人。马达加斯加和莫桑比克的海岸线比例最大，暴露程度较高，而肯尼亚和坦桑尼亚从自然海岸保护中受益最大。珊瑚礁保护了250万人免受更高的暴露，主要是在蒙巴萨，桑给巴尔和达累斯萨拉姆。考虑到莫桑比克、肯尼亚和坦桑尼亚，后者是最少的，前者是最脆弱的。在目前情况下，86个沿海地区中有17个被认为是“优先关注地区”;其中4个地区受到严重暴露，因为其90%以上的海岸线长度处于较高暴露状态（扎瓦拉、因哈里梅、曼希萨和曼德拉卡泽，均位于莫桑比克南部）。这些地点对任何目前或未来的沿海开发都至关重要，因为它们对弱势群体和投资都有很高的风险。生境的丧失将使“优先关注”地区的数量增加到24个;有些地区的受影响人口将大幅增加（例如莫桑比克的奔巴和Mossuril）。在东非，应用这些知识来确定应优先考虑哪些基于生态系统的管理，以促进社会和环境复原力是及时和紧迫的。在线版本包含补充材料，可通过10.1007/s12237-021-00930-5获得。
An index of vulnerability to coastal change, integrating indices of social vulnerability and exposure to coastal hazards, was created for East Africa to identify ‘areas of priority concern’ for risk reduction. Currently, 22% of East Africa’s coastline and 3.5 million people are at higher levels of exposure to coastal hazards, which would increase, respectively, to 39% and 6.9 million people if mangroves, coral reefs and seagrasses are lost. Madagascar and Mozambique show the largest proportion of the coastline at higher exposure, while Kenya and Tanzania benefit the most from natural coastal protection. Coral reefs protect 2.5 million people from higher exposure, mostly in Mombasa, Zanzibar and Dar es Salaam. Considering Mozambique, Kenya and Tanzania, the latter is the least, and the former is the most vulnerable. Under current conditions, 17 (out of 86) coastal districts are considered ‘areas of priority concern’; four of these are critically exposed as over 90% of their shoreline length are at higher exposure (Zavala, Inharrime, Manhiça and Mandlakaze, all in southern Mozambique). These locations are of critical concern for any present or future coastal development due to the high level of exposure posed to both vulnerable people and investments. Habitat loss would increase the number of ‘priority concern’ districts to 24; some would show great increase in the population exposed (e.g. Pemba and Mossuril in Mozambique). Applying this knowledge to identify where ecosystem-based management should be prioritised to promote social and environmental resilience is timely and urgent in East Africa.
