What case study relates to sea level change?
Kiribati.

What is happening in Kiribati ?
The president has had to buy 20km^2 of land in one of the Fijian Islands due to sea level rise. The sea level is rising at 1.2cm a year in some areas. Sea water is contaminating ground water.

The purchased land is being used for agriculture and farming projects to guarantee food security. The government launched a project to allow residents to move to neighbouring countries, NZ. Environmental refugees.

What can study relates to coastal flooding?
Bangladesh - 46% of the population live less than 10 metres above sea level.

What are the human impacts of the flooding in Bangladesh?
Embankments have been built to interrupt sediment deposition. Land-use zoning is used so locals know where is safest to build on without being flooded. The planting of 4km of mangroves.

What has occurred due to rising sea levels in Bangladesh.
2007 Cyclone Sidr in Bangladesh.

What were the short term impacts of the 2007 cyclone?
1.5 million houses damaged. $30 million worth of coastal defences destroyed. Freshwater sources were contaminated. Total cost of $1.7 billion. However, prevention strategies such as forecasting reduced casualties.

What are the social impacts of sea level rise in Bangladesh?
18% of Bangladesh is flooded per year. 15 million people displaced. 20 million people have contaminated water. 5,000 people killed per year.

What UK case study can be used for coastal recession?
The Holderness coast - 2 metres per year. £300 million in maintaining sea defences.
14 of 19
What management is in place in Mappleton.
2 rock groynes and rock revetment costing £2 million to protect the 50 properties and 2m erosion per year. However, erosion has sped up further south due to the groyne.

Kilnsea - Has now been completely lost as old management is destroyed and erosion speeds up.
