Abstract

ABSTRACT This study reviews the progress of disaster mitigation measures against tropical cyclones (TCs) in three Asian countries with different historical, social, and economic backgrounds: Bangladesh, Vietnam, and Japan. In Bangladesh, an average of 6,600 people was killed by a single TC in the 1960s, but this number had decreased to 30 in the 2010s; this reduction was due to a clear improvement in soft measures, such as weather forecasting, warning systems, and mass evacuation coordinated by volunteers. In Vietnam, several strong TCs have recently made landfall, leading to improvements in national disaster management. Although Vietnam's current disaster management budget is smaller than those of the two other countries, large-scale evacuation by local authorities is believed to have minimized casualties. In Japan, shortly after Typhoon Vera in 1959, a comprehensive law on disaster prevention was enacted, and coastal dikes were constructed nationwide, resulting in a considerable reduction in fatalities due to TCs. However, the disaster prevention facilities built in this period are now deteriorating, while Japan’s budget for disaster management is projected to be decreasing. The three countries have advanced their disaster preparedness in response to past TCs and storm surges, but new challenges have also arisen.

热带气旋和风暴潮减灾的进展:孟加拉国、越南和日本的比较研究

摘要:本研究综述了孟加拉国、越南和日本这三个具有不同历史、社会和经济背景的亚洲国家在热带气旋减灾措施方面的进展。在孟加拉国，20世纪60年代，平均有6600人死于一种TC，但这一数字在2010年代已降至30人;这一减少是由于软措施的明显改善，例如天气预报、预警系统和志愿者协调的大规模疏散。在越南，几次强台风最近登陆，导致国家灾害管理得到改善。虽然越南目前的灾害管理预算比另外两个国家要少，但据信，地方当局的大规模疏散将伤亡降到最低。1959年“维拉”台风发生后不久，日本就制定了全面的防灾法，在全国范围内修建了海岸堤坝，使台风造成的死亡人数大大减少。然而，在此期间建造的防灾设施现在正在恶化，而日本用于灾害管理的预算预计将减少。为应对过去的台风和风暴潮，这三个国家已经提高了备灾能力，但新的挑战也出现了。

期刊介绍： Coastal Engineering Journal is a peer-reviewed medium for the publication of research achievements and engineering practices in the fields of coastal, harbor and offshore engineering. The CEJ editors welcome original papers and comprehensive reviews on waves and currents, sediment motion and morphodynamics, as well as on structures and facilities. Reports on conceptual developments and predictive methods of environmental processes are also published. Topics also include hard and soft technologies related to coastal zone development, shore protection, and prevention or mitigation of coastal disasters. The journal is intended to cover not only fundamental studies on analytical models, numerical computation and laboratory experiments, but also results of field measurements and case studies of real projects.
