The economic impact of substantial sea-level rise. NASAâs is still holding that thereâs been some acceleration â but the proven global tide gauges will have none of it. The capital of the Maldives appears to be generally about 2 meters above sea level, although some of the reclaimed areas are somewhat lower. Because of the low elevation of the Maldives, this island nation is especially at risk. Since the 1950s, sea level in and around the Maldives has been rising at a rate of 0.03–0.06 inches (0.8–1.6 millimeters) per year.7,8,9 Because of the Maldivian topography, small changes in sea level translate into extensive land inundation. A 20th century acceleration in global sea–level rise. Of these, just 199 islands are inhabited with a population of slightly over 300,000 people. This map viewer illustrates the scale of potential coastal flooding after varying amounts of sea level rise. The Republic of Maldives comprises 1,190 islands in 20 atolls spread over 900 km in the Indian Ocean. Known as the “ Treasure Island”, Maldives is made up of 26 ringed shaped atolls and with a population of 450,000. Church, N.J. White, P.J. More than 90 of the inhabited Maldives islands experience annual floods.5 In 2007, a series of swells forced the evacuation of more than 1,600 people from their homes and damaged more than 500 housing units.10, Sea level rise is also likely to place added stress on the Maldives' already scarce freshwater resources.

Malé, Republic of Maldives: Ministry of Environment, Energy and Water. (The Republic of Kiribati, in the Pacific Ocean, is not far behind—see the Kiribati hot spot.3) The lack of topography in the Maldives makes it one of the nations most vulnerable to rising sea level and coastal flooding.4, Some 191 of the country's 358 inhabited islands have fewer than 5,000 people,5 and about one–third of all residents live in the capital city of Malé on North Malé Atoll. With more than 80 percent of Maldives' land area being less than one metre above mean sea level, the country is one of the lowest-lying nations in the world, leaving it vulnerable to sea swells, storm surges and other severe weather events influenced by sea level rise. Church, J.A., N.J. White, R. Coleman, K. Lambeck, and J.X. There are also tide gauge data for these islands which make direct comparison possible. 2007. Cambridge, UK, and New York, NY: Cambridge University Press. The Maldives has no hills, but some islands have dunes which can reach 2.4 meters (7.9 feet) above sea level, like the NW coast of Hithadhoo (Seenu Atoll) in Addu Atoll. Ocean Sciences 5:193–201. Tol. 7,8,9 Because of the Maldivian topography, small changes in sea level translate into extensive land inundation. Sea level has been rising by 0.07 inch (1.7 millimeters) per year since 1950, on a globally averaged basis.12 However, an average rise of 0.13 inch (3.3 millimeters) per year from 1993 to 2008 suggests that the pace of sea level rise is accelerating.13, Sea level rise is attributed to two main processes. Talley, and A. Unnikrishnan. The Maldives, one of the most stunning yet fragile nations on earth, faces the growing threat from rising sea levels and coastal storms. Population displacement indicated bottom right. Migration is also a potential solution for Maldivians. Rising seas pose a looming threat to homes and industries near the coast. New York, NY. However, in order to determine local sea level rise (SLR), one has to take into account local coastal flood levels which could be 2.8m above Mean Higher-High Water (MHHW) at extreme forecasts.

Not quite paradise: Inadequacies of environmental impact assessment in the Maldives. Rio vs Kolkata). Much of its housing and critical infrastructures, such as hospitals, airports and harbours, are concentrated on the coastline. The highest point in the country is only two feet above sea level, and 80% of the countryâs land is less than three feet below sea level. Land scarcity due to population pressure is also a major issue. Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, edited by M.L. Shum, L.D. Only 11 percent of the Maldives' inhabited islands had potable groundwater before the 2004 tsunami in the Indian Ocean.10,11 Transient seawater inundation during that event contaminated these groundwater supplies as well as soils. National Adaptation Programme of Action (NAPA), Republic of Maldives. Earth.Org has modelled what mild and extreme flooding events could look like in the Maldives’ most populous island, Malé by 2100 under a high emissions scenario as a call for awareness. Domingues, C.M., J.A. The Maldives are the exposed top of a long, narrow submarine ridge whose average height is 1 to 2 m (3 to 6 ft) above sea level. 2007.
