the "safe development" paradox Flashcards
what is the coupled-system argument?
building defences tend to destroy natural “defensive” environments. this tends to make hazard impacts worse, which encourages more defences.
what happens if more homes and infrastructures get built in a hazardous environment?
the more they drive investment in hazard defences. the more defence- the more development behind them.
what happens to levee when an event occurs?
levee hight increases and the tax revenue decreases when this occurs.
why is the coupled system a continuous circle?
as the next disaster that happens is more severe bur recovers more rapidly, and then more protection comes up which further increases causes of events.
why are these events becomes more important?
as the coastal watershed and shorelike countries are increasing massively.
how many countries per person/mile squares has been added in coastal shoreline?
125
how many countries per person/mile squares has been added in coastal watershed?
99
what percentage have house size increased at the coast?
125% since 1960
what natural hazards come to the coast?
sea-level rise, storm frequency, magnitude increase. only make storms worse.
what is the disaster paradox?
greater losses in part due to hazards getting worse, more people in harm’s way, generally more infrastructure.
what is driving this development of housing?
positive feeback between development and protection.
how many properties in England are at rsk of damage from coastal flooding?
520,000
how many propterties in Uk are at risk of being lost through coastal erosion?
8,900
what is the samage sum from flooding and erosion on an average year?
260 million pounds
by 2080, how many more properties will be at significant flood risk?
1.5 million
