- 5.5C: Impacts of flooding
- Environmental
- Soils
- Wildlife in the soils can be poisoned by polluted flood water
- Ecosystems
- In a natural ecosystem, flooding is good! It replenishes groundwater, fills wetlands, can trigger breeding
- However, if an ecosystem has been impacted by human activities then flooding can become negative
- Excessive overland flow can lead to excess in nutrients causing eutrophication and destruction of aquatic plants
- However, if an ecosystem has been impacted by human activities then flooding can become negative
- In a natural ecosystem, flooding is good! It replenishes groundwater, fills wetlands, can trigger breeding
- TLD, river banks eroded adding to future flood risks. Rivers also choked with debris/sewage
- Soils
- Social impacts
- Post-flood morbidity from disease such as cholera
- Structural damage to property
- Extremely high in megacities such as Mumbai, where growth has outstripped flood defence systems
- TLD 2015
- 5,200 homes flooded
- Local services closed
- Economic impacts
- Escalating food prices due to shortages of products as agriculture is impacted
- Services/busineses being flooded mean people are out of jobs
- E.g. 1,000 lost their jobs in 2015 TLD flooding due to flooding of a factory
- May reduce income from tourism
- Cumbria experienced dry tourism for a year after 2015 floods
- TLD
- £400-500 million in costs
- £250 million in insurance
- Flooding statistics
- Between 1990-2010, there were 3,000 flooding disasters globally
- 90% of flood deaths in Asia
- 50% of economic damage via floods in Asia
