Natural disasters, such as earthquakes, tsunamis, and tropical storms, have a devastating impact on small islands around the world. These islands often have dense populations and limited infrastructure, making them particularly vulnerable to climate change and extreme weather events. In facing such disasters, mitigation and adaptation strategies are very important to ensure the survival of existing communities and ecosystems. In many cases, the impact of natural disasters on small islands can be more severe than on the mainland. For example, islands in the Pacific Ocean, such as Tuvalu and Kiribati, have experienced rising sea levels caused by global warming. This phenomenon threatens the existence of these islands, which have the potential to disappear in the next few decades. When sea water rises, not only land is threatened, but also clean water sources and agricultural land which support people’s lives. Tsunamis, as another form of devastating natural disaster, can destroy vital infrastructure in a matter of seconds. Small islands located near fault zones, such as Aceh in Indonesia, are often targets of deadly tsunamis. Loss of housing, health facilities and schools can worsen social and economic conditions. In situations like this, recovery efforts require a long time and support from the government and international institutions. Tropical storms and strong winds also pose a significant threat to small islands. Heavy rains can cause landslides and floods, damaging agriculture and causing food shortages. In addition, damage to coral reefs and marine ecosystems due to storms has a direct impact on the fishing industry, which is the main livelihood of many island residents. Monitoring and disaster management activities are very important on small islands. Strong infrastructure, such as early warning systems, can save lives by alerting residents to impending danger. Training for local communities in evacuation and first aid is also a key factor in reducing the impact of disasters. Community participation in disaster management planning must be increased. Education about climate change and disaster risk mitigation must be the main agenda, so that people can equip themselves to face existing challenges. In addition, cross-country cooperation and support from international institutions can strengthen the capacity of small islands to respond to the challenges of natural disasters. Overall, natural disasters have the potential to devastate small islands with dire impacts. However, with proper planning and community involvement, people on these islands can be better prepared to face and reduce the risks posed by natural disasters. and well-planned climate adaptation.
