Climate change has become a crucial issue that affects various aspects of life, one of which is the intensity and frequency of global floods. This phenomenon is caused by various factors, including increasing global temperatures, reducing green land, and changes in rainfall patterns. The increase in temperature due to greenhouse gas emissions causes melting of polar ice, raising sea levels. This contributes to increasingly severe coastal flooding in various countries, especially those with low-lying areas. In addition to rising sea levels, increasingly unpredictable rainfall patterns are also causing more frequent flooding. More extreme weather systems, such as tropical storms and torrential rains, are triggered by climate change, causing rivers to overflow. In recent years, various regions throughout the world, from Southeast Asia, Europe to America, have experienced floods which have had significant social and economic impacts. The environmental impact of global flooding is increasingly worrying, causing ecosystem damage, loss of biodiversity and destroying agricultural land. Flooding accelerates the process of soil erosion and changes natural waterways, leading to loss of habitat for various species. Additionally, standing water resulting from floods often becomes a breeding ground for disease, increasing health risks for affected populations. The economic sector also feels a major impact due to climate change and flooding. Damaged infrastructure, such as bridges and highways, results in huge financial losses. The agricultural sector was also seriously affected, because floods damaged crops and reduced yields. This could lead to rising food prices and food security problems in some areas that depend on agriculture for livelihoods. Floods also cause social upheaval. People who lose their homes and livelihoods often have to move to other areas or rely on humanitarian assistance. Tensions between communities can increase, especially if resources are limited. In this context, the importance of spatial planning and flood risk mitigation must be considered by the government and related institutions to reduce wider impacts. Apart from mitigation, adaptation to climate change is also an important aspect in dealing with global flooding. The development of early warning systems, ecosystem restoration and the application of green technology can help reduce the risk of flooding. The community also needs to be involved in the planning and implementation process of mitigation strategies so that they are aware of potential risks and can contribute to protecting the environment. Overall, the impact of climate change on global flooding is a complex issue that requires serious attention from all parties. In facing this challenge, international collaboration, ongoing research, and concrete steps in mitigation and adaptation will be key in protecting society and the environment from the increasing threat of flooding.
