Final answer:
Non-structural flood protection measures focus on policies and practices rather than physical barriers. Zoning regulations and early warning systems are examples, along with ecosystem conservation which can naturally mitigate flooding.
Step-by-step explanation:
Examples of non-structural flood protection measures include:
- Creating floodplain zoning regulations
- Implementing early warning systems
Unlike building levees or constructing flood walls, which are structural measures, non-structural approaches often involve policies, practices, and planning strategies. Establishing zoning regulations that prevent construction in high-risk flood areas can significantly reduce the impacts of flooding. Additionally, early warning systems provide critical information allowing communities to prepare and respond more effectively to flood events.
Promoting ecosystem conservation, such as wetlands and mangrove forests, is another crucial non-structural strategy. These ecosystems act as natural barriers against flooding and storm surges, reducing the need for engineered solutions. Studies have shown that the presence of natural forests can reduce flood risks significantly. In contrast, non-native plantations may not have the same flood mitigation effects and could even increase flood hazards.
