Tuvalu has been brought to international attention as a country in danger of submerging due to the impact of global warming, because most of its landmass is low-lying atoll only 1 to 3 meters above sea level. On the other hand, a study report says that the main cause of the existing coastal erosion and tidal surge impact is the increase of environmental load by population growth (sand supply decrease due to deterioration of water quality, and constructing barriers for accretion of sand) and sprawl of residential area (inhabitation in flood prone areas, and extracting earth and sand from coastal areas) rather than precipitation change or sea level rise due to global warming. Therefore, a comprehensive study on the impact of human activities is needed for the island’s long-term sustainability. |
