Study Notes
Nature-Based Solutions for Urban Resilience
- Nature-based solutions (NBS) are increasingly recognized for their role in urban resilience, endorsed by international agreements like the Sendai Framework for Disaster Risk Reduction and the Paris Climate Agreement.
- Mountainous cities are vulnerable to flash floods, erosion, and landslides due to steep slopes and extensive stream networks.
- River cities face seasonal water-level fluctuations and flooding, despite benefiting from fertile soils and river trading opportunities.
- Delta cities are flood-prone regions influenced by hydrological dynamics and home to productive wetland ecosystems and soils.
- Coastal cities benefit from coastal ecosystem services but face threats like sea level rise, coastal flooding, and erosion.
- Extensive green roofs consist of bioengineered growth medium, membranes, buffers, and insulation, with drought-resistant plants.
- Intensive green roofs have a thicker substrate layer, provide amenities, lower building energy bills, and offer habitats for species like birds and bees.
- Rooftop gardens are a type of intensive green roof, serving as productive urban farms with higher installation and maintenance costs.
- Smart green roofs use a crate system to store rainwater for irrigation, offering dynamic control over water drainage.
- Facade-bounded greening uses technology for irrigation and special substrates, while ground-based green facades consist of climbing plants rooted in ground planters.
- Phytoremediation forests clean polluted soils using trees and shrubs with specific metabolic qualities.
- Ecological forest corridors provide critical linkages, screening, and safe movement of species in urban landscapes, improving ecological conditions and facilitating movement of diverse species.
