Sinking islands battle tides

Paradise lost

Small island nations around the world are already feeling the impact of rising sea levels. And probably none more so than the Maldives in the Indian Ocean, which is considered the lowest-elevation country on the planet. The average elevation of its 26 atolls is just 1.5 meters (5 feet) above sea level – so it wouldn’t take much for the country to be rendered completely uninhabitable.

Underwater property

Rising waters have already caused some islanders to flee their homes for higher ground. On the Kiribati islands in the Pacific, some villages have been completely flooded. Local farmers also have to worry about encroachment of saltwater on their crops. The ever-approaching sea means less surface area for agriculture, and a greater need to transport food from afar.

Temporary escape

Around 113,000 people call the Kiribati islands home. Locals who’ve been displaced often end up on the main island of South Tarawa, which has a sea wall to protect low-lying properties on the shore from rising waters – but that’s no permanent solution.

Floating in the floodwaters

Although Bangladesh is on the mainland of Asia, it faces a huge risk from climate change due to its low-lying geography and population density. A mere 1-meter (3-foot) rise in sea level would cause half the country be under water. Communities have started adapting to increased flooding by using floating agricultural technology to grow their crops.

Sinking world heritage

Venice in northeastern Italy is no stranger to flooding – and according to experts, the iconic city will continue to sink. The Italian government has invested 9.6 billion euros ($7 billion) in the “Moses” water barrier project, designed to protect the city – a UNESCO World Heritage site – from rising oceans and high tides. The barriers are expected to be completed by 2016.
