The impact of global flooding on ecosystems creates significant changes in various aspects of the environment. One of the biggest impacts is increasing salinity in coastal areas. Flood water mixed with sea water can cause damage to natural habitats such as mangroves, coral reefs and seagrass beds, which serve as homes for various species. Flora and fauna that cannot tolerate high salinity have the potential to experience population decline, affecting the local food chain. Additionally, global flooding often results in the stripping of fertile land. When water flows through agricultural land, organic matter and important nutrients can be removed, thereby reducing soil fertility. This has a negative impact on agricultural productivity, which risks threatening food security. Farmers may face difficulties recovering their land after flooding, complicating agricultural processes and triggering migration of rural residents to cities. Another impact of flooding is pollution of freshwater ecosystems. Waterways contaminated by industrial waste, chemicals and dirt from residential areas result in a decrease in water quality. This not only kills various species of fish and other aquatic organisms, but also creates problems for local communities who depend on clean water for daily needs. Then, floods also change species distribution patterns. Some species can adapt easily to environmental changes, while others may be endangered. Flora and fauna moving to new habitats can create an imbalance in the ecosystem, paving the way for invasive species. This can lead to conflict between local and foreign species, which in turn affects biodiversity. Climate change and flooding influence each other. As global temperatures increase, the frequency and intensity of flooding is expected to increase. This creates a cycle that is difficult to overcome, in which ecosystems are increasingly stressed by competition for dwindling natural resources. Ecosystem adaptation is becoming increasingly difficult, and many species are having to adapt faster than they are capable of. From a social perspective, the impact of flooding on ecosystems also touches the cultural and economic aspects of local communities. The loss of natural resources due to flooding can be detrimental to communities that depend on these natural resources for their daily lives. Ecosystem preservation is important not only for the survival of species, but also for supporting local economies and community culture. Effective flood risk management is crucial to reducing these negative impacts. Ecosystem restoration efforts, creating buffer zones, and sustainable water resource management can help create balance. In addition, increasing public awareness regarding the importance of protecting the environment and utilizing environmentally friendly technology will greatly help mitigate future disasters. By considering the entire spectrum of flood impacts on ecosystems, holistic measures in environmental protection become more important. In addition, public policy support that encourages sustainability and rehabilitation of natural resources must be prioritized to ensure ecosystem resilience to face global flood challenges in the future.
