Edited by Hussein Shihab. The Maldives are vulnerable to sea level rise because they are not vulnerable to storms. Although that statement may sound like a paradox, it is roughly analogous to our discussion of wetlands, in which we noted that areas with low tidal ranges are more vulnerable than areas with large astronomic and storm tides.
Because storm surges are rarely over 30 cm, it has been safe to develop land that is only about 40 cm above high tide, and most of the population lives on land within two meters of sea level; virtually the entire nation is within four meters of sea level.
In FebruaryI had the pleasure of visiting about 20 islands in the Republic of Maldives along with Dr. Colin Woodroffe and a number of engineers from Delft Hydraulics Laboratory over a period of about 10 days. Particularly useful was Dr. Woodroffe's decision to bring along a rod and transom, which made it possible to measure the elevations of a typical transect across several of the islands.
The following sections recount some of my observations and courses of action that seem reasonable given what I was able to learn. The capital of the Maldives appears to be generally about 2 meters above sea level, although some of the reclaimed areas are somewhat lower.
During storms in andthe reclaimed areas were flooded by low-period waves. Although the damage was minimal, the experience was a forceful reminder of how vulnerable the Maldives can be to even a small rise in water levels, and is generall viewed as the catalyst that prompted officials to begin considering the implications of higher sea level.
The initial response to this threat was to begin construction of a series of breakwaters on the outer coast of Male, which will protect the capital from damaging storm waves. Nevertheless, they would not prevent a flooding from a sustained rise in water levels.
Fortunately, even a one meter rise in sea level would leave Male somewhat above the level of high tide.
A more immediate concern is the dwindling of the freshwater table. With over 50, residents on one square kilometer of land, the annual recharge into the aquifer is much less than annual withdrawals for consumption. As a result, fresh water is only available in the center of the island, and even there, the freshwater lens is narrowing.
Fortunately, there is ample rooftop collection to supply drinking water; but cleaning and commercial uses still depend on groundwater.
Because the groundwater table will be largely "mined" in the next decade, one might view saltwater intrusion do to sea level rise as irrelevant. Certainly a policy response will be necessary in the near term even without sea level rise, such as importing water from another island.
Nevertheless, once these responses are in place, the groundwater would continue to supply some of Male's needs. Sea level rise, however, would reduce the freshwater storage capacity of Male, as well as any adjacent islands that might be a supplemental source.
In response to dwindling water supplies and overcrowding in general, the Maldives have embarked on an ambitious plan to create a number of new cities on islands that are relatively uncrowded today.
The first island we visited was Eydhafushi, a well planned community in the Baa atoll where freshwater is still plentiful.
The island also has a reasonable elevation.
With people, this island is less crowded than Male but more so than most islands in the Republic. It is probably the most vulnerable we visited.Use the interactive map by entering in any number of inches – the map will show what areas would be flooded or at risk and the left side bar will display the number of people displaced.

In early August, the heaviest flooding moved southward along the Indus River from severely affected northern regions toward western Punjab, where at least 1,, acres (, ha) of cropland were destroyed, and toward the southern province of Sindh.
The affected crops included cotton, sugarcane, rice, pulses, tobacco and animal fodder. The Maldives, consisting of over 1, islands to the west of India, is the world's lowest-lying nation.
