Geography Unit 2 - coping with climate change - TUVALU CASE STUDY

TUVALU


Location:
  • 9 small islands in the pacific ocean.
  • north-east of Australia




Background:
  • in 2005, population was 10,500, none more than 5m above sea level
  • The economy relies on semi-subsistence farming&fishing, as well as foreign aid.

Risks:
  • The low lying islands are being flooded more frequently due to sea level rises of 1-2m per year.
  • Coral atolls flood from below, pushing salt water up through the ground, poisoning pulaka pits where Tuvalians grow starchy tubers for food.
  • Poor coastal management & building materials
  • Road bulding has tripped the region of much vegetation

Options:
  • Relocate - in 2001, NZ agreed to accept 75 Tuvalians per year, possibly untill 2050.
  • Change behaviour - in 2000, Tuvalu joined UN to bring it's climate change plight to the worlds attention.
  • Modify the threat - Beach mining regulated to reduce erosion risk.
  • Prevent the loss - Salt-tolerant crops to replace traditional pulaka.
