Global flooding is one of the most pressing challenges in facing climate change. This threat is not just limited to one country, but affects the entire world, and its impact is becoming increasingly evident. Rising global temperatures cause melting of polar ice and rising sea levels, which contribute to the frequency and intensity of flooding in many regions. One of the main factors contributing to global flooding is climate change. Rising atmospheric temperatures allow seawater to absorb more water vapor, increasing the amount of extreme rainfall. According to the IPCC report, by 2100, sea levels could rise from one to two meters if greenhouse gas emissions are not reduced. This increase will cause coastal areas to become more vulnerable to flooding, damaging ecosystems, infrastructure and socio-economic processes. Additionally, rapid urbanization increases the risk of flooding. In many large cities, poor water management and land compaction result in ineffective drainage. Heavy rain can cause water bodies to overflow, disrupting residents’ daily lives. For example, Jakarta, known for its flooding problems, has faced a number of major flooding events that have cost billions of dollars to recover from. The increase in population also worsens the situation. With more people living in flood-prone areas, the risk of loss of life and economic loss is higher. Regions like Bangladesh and Thailand have a long history of flooding, and climate change is only exacerbating the problem. Here, evacuation and disaster mitigation become very crucial. Social inequality also affects society’s ability to deal with floods. Underprivileged communities often do not have access to the resources to build flood-resistant infrastructure. This creates a vicious circle in which they are most vulnerable to experiencing the adverse impacts of climate change. Various technologies are starting to be developed to reduce the risk of flooding. For example, early warning systems and flood risk mapping using satellite data can help communities to prepare and reduce losses. In addition, implementing sustainable water resource management policies is also very important to overcome this challenge. Collective awareness regarding the threat of global flooding must be strengthened. Education about climate change and mitigation practices can be the first step to creating a more resilient society. Communities that are actively involved in flood risk planning and mitigation have a greater chance of coping better with disasters. From a policy aspect, governments around the world must work together to address this problem effectively. Law enforcement to preserve the environment and sustainable development initiatives need to be integrated into city planning. In addition, climate change adaptation must also be a priority in development policies, ensuring that preventive measures are taken before the situation gets worse. The need for coordinated action between parties is also very important in overcoming the threat of flooding. Collaboration between governments, non-governmental organizations and civil society can form a more holistic approach. This is not only about mitigation, but also post-disaster preparedness and recovery which must be well designed. By understanding the threat of global flooding, it is hoped that all parties will be more alert and prepared to face existing challenges. Awareness and preparedness are the keys to protecting various valuable assets, from human life to the surrounding environment.
