Consequences of rising sea levels
Case Study: Tuvalu
|
|
Describe the location:
It is located in in the Pacific Ocean, midway between
Australia and Hawaii. It’s some of it’s nearby neighbors are Fiji and Samoa.
They are formally known as Ellice Island

Location map + sea level rise
|
Explain why it is vulnerable to sea level rise…
The island is only 5m in height which makes it extremely vulnerable
to rising sea levels, experts predict that Tuvalu will disappear by 2050.
·
The highest wave called King Tide is 3m high
·
Tuvalu is located in a area where the sea
levels are particularly high
·
Most of the island are made of coral reefs,
since they are porous, water can seep into inland areas
·
Most of Tuvalu’s infrastructure such as the
airport is located by the coast, so it poses an extreme risk
·
They have very little fresh groundwater and
have to rely on rainwater for fresh water

Predicted IMPACTS (SEEP) Evidence please..
Social
-Evacuation of people to the main island of Funafuti,
which now host half of Tuvalu’s population.
-Overcrowding due to the huge inter migration to the main
island.
- People are forced to leave islands such as Tipuku
Salvilivili has already been abandoned due to the rapidly rising sea levels
swallowing the island
-The island main source of food, Pulaka is being killed by
the intrusion of saltwater, this leads to diminish in food supply.
-Travelling on the island becomes a problem as it is
constantly flooded
Economic
-Coconut plantations are being killed off, this is
concerning as dried coconut meat plays a large part in Tuvalu’s economy
-Hotels and buildings are constantly being flooded, this
hampers trade, business and tourism
- Access to the island becomes limited due to the seawater
covering the runway, this hampers materials from being imported into Tuvalu
Environmental
-Groundwater will become undrinkable as the sea water
heads inland
-Crops cannot be planted as the seawater intrudes into the
plantations
-The world would be alerted to global warming by using the
sinking of Tuvalu as an example
Political
-The G3 might be held responsible for not rectifying the
Kyoto protocol
|
What is being done to prevent OR manage the threat?
-Houses and buildings are being improved to combat
flooding such as implementing ten foot stilts and raise the house to prevent
it from being damaged by floods.
-The citizens are Tuvalu are being evacuation to either
the mainland or to nearby countries such as New Zealand
In general terms, the government is planning to evacuate
the entire population of Tuvalu before in sinks into the ocean, the current
outlook for Tuvalu is looking bleak
