A mangrove tree grows on the Southern tip of the Funafuti Atoll. Tuvalu has a population just over 10,000 people, most of whom live in the country's capital Funafuti. Increasing urbanisation, along with climate change, pose big threats to this tiny Pacific country. Migration from the outer islands to the main island of Fongafale is placing increasing pressure on water supplies and land availability, while employment opportunities in the small formal sector are limited. Moreover, stronger 'King Tides', Saltwater intrusion into the groundwater and extreme weather events are making this island nation one of the most vulnerable countries in the world. The country's Prime Minister had asked Australia and New Zealand to consider taking in Tuvaluans when the low-lying islands eventually become uninhabitable.
