Ecosystem-based disaster risk reduction is when people work with nature to reduce the risk of disasters. By protecting and improving ecosystems, like forests and wetlands, people can help make the environment safer for everyone and protect them from harm when natural disasters strike. For example, forests can help reduce floods by trapping water and preventing it from coming down too quickly. Wetlands can absorb excess water and filter out harmful materials. People can also help protect homes and communities by planting trees around them, which provide shade, keep the air clean, and can help keep out strong winds.
