Scientists predict that the sea level could rise up to 90 centimeters over the next hundred years. This will cause affected both the physical and biological models. Many of the Thailand Environment Institute estimated in a study to prepare a plan of action with the national climate change of that. There is obviously the possibility of water shortages in the country's largest watershed. And flooding more frequent and more severe in wetlands. Considering the possibility of higher water levels in the oceans. Especially in the coastal areas of Bangkok. Which is the capital and economic center. It also has a high population density. And above sea level is one meter only the saltwater intrusion will come in the river to 40 kilometers a serious impact on agricultural areas that are sensitive to the balance of fresh and salt water in this city. the risk of damage from events Inundation and Flood. To cause damage to the infrastructure. Homes of many people. Including the impact on the economy will follow the coastal areas will be affected as well. Thailand has a coastline of about 2490 km, including the agricultural area. Aquaculture resources The area is a tourist attraction And housing The impact of climate change on coastal areas varies is the case because the country has many coastal areas, such as coastal areas, cliffs. The collapse may have happened to the rock that is not solid enough. However, this process will happen slowly. The beach from Phetchaburi to Songkhla, which looks at the narrow coast will disappear. And the beach is retracted into the plains, the sea, the mangrove area has reduced thickness and may be replaced by Lane Beach. Because dead plants from sea level rise. Saltwater pools dropped and replaced by Lane Beach. At the mouth of the river to submerge cause erosion of the basin side. Lake shore, the water will have more space and may have more saltwater intrusion.
