Global flooding has become one of the most pressing issues in the context of climate change. The latest data shows that the frequency and intensity of floods is increasing in various parts of the world. According to a report from the Intergovernmental Panel on Climate Change (IPCC), increasing extreme rainfall, deforestation and uncontrolled urbanization contribute to the high risk of flooding. One of the significant impacts of climate change is increasing global temperatures, which serves to accelerate evaporation and change weather patterns. Countries like Pakistan and Bangladesh experience major floods due to excessive rainfall. In 2022, Pakistan faces floods that cause economic losses running into billions of dollars and affect millions of people. Research shows that climate change plays a major role in these extreme weather conditions, which add pressure to infrastructure and settlement systems. In Europe, flooding is also a serious threat. Countries such as Germany and Belgium experienced severe flooding in 2021 that killed hundreds of people. Changes in river flow patterns and soggy soil due to deforestation are the main causes of this disaster. Data from the European Environment Agency (EEA) shows that central Europe is in the zone most vulnerable to flooding due to climate change. In the Southeast Asian context, floods are often combined with other impacts such as landslides and coastal erosion. Indonesia, which is located in a strategic position, faces the threat of tidal floods due to rising sea levels. Predictions show Jakarta’s coastal areas will sink in the next decade if mitigation measures are not taken. Investment in green infrastructure such as rain gardens and storage reservoirs is a much-discussed solution. Meanwhile, countries in Africa were also not spared from the impact of flooding. Payment for climate components through nature-based solutions is a strategy to mitigate the impacts of climate change. Research shows that planting trees and restoring ecosystems can help reduce water flow and flood risk. Climate change not only affects the environment but also affects public health. Floods can cause the spread of disease, contaminate clean water sources, and damage sanitation systems. For example, following major Floods in Mozambique in 2019, the risk of cholera and other infectious diseases increased sharply. Quick and effective treatment is needed to reduce post-flood health risks. With all the impacts, community outreach and education are important components in mitigating flood disasters. The community needs to be involved in spatial planning and management, to reduce the risk of flooding in the future. Educational efforts regarding climate change and its impacts are very relevant to increasing awareness and preparing communities to face disasters. By integrating climate change policies with holistic planning, we can strengthen community resilience to flood risk. Government offices around the world are expected to work together to fund research and implement sustainable innovation. Only with a collaborative approach that targets social, economic and environmental aspects can the effects of climate change be minimized.
