Consequences of coastal recession on communities Flashcards
The 3 categories of costs of coastal recession
- Economic
- Social
- Environmental
Economic costs of coastal recession
- loss of property in the form of homes, businesses and farmland.
- easy to quanitfy
Why are economic losses due to erosion small?
- erosion happens slowly, small number of properties affected over a long period of time
- property at risk loses its value long before it is destroyed due to erosion
- areas of high density population can be protected by coastal defences
Social costs of coastal recession
Costs of relocation and loss of livelihood/jobs (can be quantified), and impact on health (stress/worry), harder to quantify.
Environmental coasts of coastal recession
Loss of coastal ecosystems and habitats. Impossible to quantify economically, but likely to be small
Amenity value
The value in cultural, human wellbeing and economic terms of an attractive environment people enjoy using.
Costs to a whole village at risk of coastal recession
- falling property values
- inability to sell property
- inability to insure against the loss
- loss of their major asset, hard to buy new home
- increasingly unattractive environment
Differences in losses depend on
Type of loss
- location specific, some homes more expensive than others
- farmland less likely to cost as much
- roads very expensive to replace £150,000-£250000
Case study help with losses due to erosion
UK- coastal change pathfinder. Very little help
Case studies coastal flooding in developed and developing nations
Developed - Netherlands, UK, USA, Phillipines
Case study coastal engineering project to reduce risk from future storm surges
Netherlands - Deltawerken hard engineering megaproject
case studies environmental refugees
Maldives, Tuvalu, Seychelles
