Global flooding is a phenomenon that is increasingly occurring and is triggered by various factors. The main causes of global flooding include climate change, rapid urbanization and deforestation. Climate change, due to global warming, causes extreme weather such as heavy rains and storms, which can increase the volume of water flow in rivers and other waterways. Urbanization narrows water catchment space, causing puddles during high rainfall. Meanwhile, deforestation reduces the soil’s ability to absorb water, speeding up the flow of water into rivers. The impact of global flooding on the environment is very significant. One of the impacts is ecosystem damage. When floods hit, many natural habitats are destroyed, destroying the homes of various species of flora and fauna. This process can trigger the extinction of species, especially in areas that are already threatened. Apart from that, floods also bring pollution. Hazardous materials such as industrial waste and chemicals can be carried by currents to other areas, polluting soil and water sources. This threatens public health and disrupts the quality of water used for irrigation in agriculture. This pollution can cause long-term health problems for exposed residents. Global flooding also has implications for land changes. When water flows rapidly, soil erosion can occur significantly, removing the fertile layer that is important for agriculture. This has the potential to reduce agricultural yields and worsen the existing food crisis. One other impact that needs to be considered is increasing climate change. When floods occur, CO2 trapped in the soil can be released into the atmosphere, exacerbating global warming. This creates a dangerous cycle in which flooding and climate change reinforce each other. Mitigating the impact of global flooding can be done through various strategies. Forest rehabilitation is one solution, helping to increase water absorption and reduce the risk of flooding. Apart from that, good spatial management can help minimize the impact of urbanization on the environment. The development of green infrastructure, such as water storage parks, can also reduce the flow of puddles during heavy rain. Meanwhile, it is important for the government and society to increase awareness and preparedness for global flood risks. Through education and training, it is hoped that the community can increase their capacity to deal with emergency situations due to flooding, so that the impact on the environment can be minimized. Overall, global flooding has far-reaching impacts on the environment. The causes related to climate change, urbanization and deforestation must be addressed comprehensively to prevent more severe damage. Collaborative efforts from various parties are important to create sustainable solutions and reduce the risk of flooding in the future.
