非洲海岸被认为是全世界最敏感的地区之一，因为它们易受自然灾害的影响，而且社会脆弱性很高。这项研究提出了东非的第一个区域评估，结合了沿海灾害和社会脆弱性的暴露程度，并考虑到对教科文组织世界遗产的影响。结果表明，东非海岸线的1340公里（12%）显示出高或非常高的暴露于沿海灾害，主要是在莫桑比克（625公里）和马达加斯加（614公里）。坦桑尼亚的受影响程度最低，其57%的海岸线被归类为极低或低受影响。然而，沿海栖息地的丧失可能会大大增加肯尼亚和坦桑尼亚的暴露水平。虽然侵蚀可能是当地的一个问题，但60%的东非海岸相对稳定。相对于区域指数，教科文组织遗产地并不处于暴露程度高的地区，但如果侵蚀率增加或自然保护丧失，有些遗产地可能处于暴露程度高的地区。
Africa’s coasts are considered one of the most sensitive areas worldwide due to their exposure to natural hazards and high social vulnerability. This study presents the first regional assessment for East Africa that combines level of exposure to coastal hazards and social vulnerability, and considers implications to UNESCO World Heritage Sites. Results indicate that 1340 km (12%) of the Eastern Africa coastline show high or very high exposure to coastal hazards, mainly in Mozambique (625 km) and Madagascar (614 km). Tanzania shows the least level of exposure with 57% of its coastline classified as very low or low exposure. However, coastal habitat loss could increase dramatically the exposure levels in Kenya and Tanzania. Although erosion may be an issue locally, 60% of the Eastern Africa coast is relatively stable. Relative to the regional index, the UNESCO Heritage Sites are not in areas showing high levels of exposure, but some may be if erosion rates increase or natural protection is lost.
