Between 1971 and 2014, storms played a significant role in increasing the land area of Tuvalu, a small island nation in the Pacific Ocean. The study, led by the University of Auckland and published in Nature Communications in February 2018, found that storms contributed to a net gain of 73.5 hectares of land, which represents a 2.9% increase in Tuvalu's total surface area. This growth occurred despite the local sea level rising at twice the global average, reaching 3.9 mm per year. The researchers analyzed 101 islands in the Tuvalu archipelago by comparing aerial photographs from 1971 and 1984 with satellite images taken between 2004 and 2015. Tuvalu is a group of nine atolls spread across an oceanic area roughly five times the size of New Zealand, with only about 26 square kilometers of land above water. It is the fourth smallest country in the world, with just 11 islands inhabited permanently and only two having more than 600 residents. The country has often been portrayed as a "drowning nation" due to its vulnerability to rising sea levels and climate change, but this study suggests a more complex picture. According to the study, eight of the nine atolls in Tuvalu have gained land, with nearly three-quarters of the 101 islands expanding in size. Some islands grew by as much as 113%, while others saw smaller increases. However, about 27% of the islands—mainly the smaller, sandy ones—actually shrank. The only atoll in decline, Nanumea, lost less than 0.01% of its surface area. The overall trend shows a positive balance, but the changes were not uniform across all islands. The researchers suggest that extreme weather events, such as the powerful cyclone Bebe in 1972, contribute to the growth of larger islands. These storms erode sand and gravel from coral reefs, and waves then deposit this material on the shores. Paul Kench, one of the study's authors, explains that this process may explain the expansion of islands composed of a mix of sand and gravel. Smaller, sandy islands, however, are more prone to erosion and tend to lose land more significantly. The study clarifies that rising sea levels alone are not responsible for the islands' growth. Instead, it is the storms that bring in sediment, and the researchers emphasize that sea level rise is just one factor among others, including sediment supply and wave patterns. The study does not cover developments after 2014 or address issues like fresh water availability or flooding. The authors conclude that Tuvalu's islands are likely to remain habitable throughout the century, even though land loss could affect certain areas. They highlight the need for adaptive strategies that consider the varied characteristics of different islands. Notably, only one of the 101 islands has disappeared entirely, with a loss of just 0.08 hectares on the Nukufetau atoll.
