Nature-Based Solutions: Wetlands, Dunes, and Forests for Risk Reduction
Nature-based solutions use natural ecosystems like wetlands, dunes, and forests to reduce environmental risks such as flooding, erosion, and climate impacts. Wetlands absorb excess water, lowering flood risk; dunes act as natural barriers against storm surges and coastal erosion; and forests stabilize soil, prevent landslides, and regulate water flow. These approaches support biodiversity, enhance resilience, and offer sustainable, cost-effective alternatives to engineered infrastructure.

❓ Frequently Asked Questions
What are nature-based solutions in the context of risk reduction?
Nature-based solutions use natural ecosystems like wetlands, dunes, and forests to reduce environmental risks such as flooding and erosion, often complementing built infrastructure.
How do wetlands reduce flood risk?
Wetlands absorb and slow excess water, helping to lower flood peaks and delay runoff after heavy rainfall.
What role do coastal dunes play in protection?
Dunes act as natural barriers against storm surges and coastal erosion by absorbing wave energy and reducing the impact of high seas on shorelines.
How do forests contribute to risk reduction?
Forests stabilize soils and slopes, reducing erosion, and they can enhance climate resilience by supporting local hydrology and carbon storage.
Should nature-based solutions replace traditional infrastructure?
They are most effective when used alongside traditional measures as part of an integrated risk-management plan, tailored to the site and maintained over time.
