infrastructure
challenges

2. Urbanisation

3. Urbanisation
Impervious surface
Increased water enters river systems

4. New
Development

5. High rise, Shopping malls
Impervious surface
Weight on alluvial soil contributes to land subsidence

6. Informal
housing
settlements

7. Informal housing on river banks
Vulnerable to flood
Inadequate supply of piped water
Increased use of groundwater

unpredictable and severe weather events
Combined with a high tide and ocean swell creates
conditions for floods.

14. Land
Subsidence

15. Land subsidence
Result of pumping of groundwater
Weight of new development
Natural subsidence of alluvial soil
Increases the amount of land that is below sea level
Increases vulnerability to flooding

16. Cost of Aid

17. Cost of emergency aid and compensation for
