Structural Approaches in Building Community Resilience to Climate Change
How It Works
Seawall
Wall that is constructed along the coast to prevent the sea from advancing onto the land
Protects people, properties and environments from coastal floods
Polnder
Low-lying land that is surrounded and protected by barriers known as dykes
Excess water is then pumped out of the polnder
Protects people, properties and environments from sea level rise and coastal floods
Water Storage Tanks
Infrastructure to store excess stormwater during periods of excessive rainfall to slow water from rushing into canals and drains, prevents flooding of canals and drains
Limitations
Economic: Costly to build structures, especially for developing countries
Must be regularly monitored and enhanced regularly
Social: May require the eviction of informal communities
