 Scientists have listed three deltas in the world most affected by rising sea levels, namely the Ganges, Brahmaputra in Bangladesh, the Nile in Egypt, and a Mekong Delta in Vietnam. Sea level rises are destroying coastlines and protected forests, jeopardizing human lives and the food security of approximately 18 million people living along the Mekong Delta in Vietnam. Khamau is the southernmost region of the S-shaped country of Vietnam. Bordered on two sides by the East Sea and the Gulf of Thailand, its 254 kilometer long coastline spanning from east to west is hippified by its wetlands. The profits lies at a crucial strategic position along the Mekong Delta and serves as a critical biosphere reserve for the region and the world. Apart from its modern significance, every inch of the sacred land in Khamau cave that was discovered by the Vietnamese of antiquity has been preserved by generations through the peaks and troughs and the twists and turns of the country's long history. Scientists estimate that every year tens of meters of seawater intrude inland. The sea level rise in Khamau averages from 1 millimeter to 4 millimeters and is showing increasingly serious signs that this land is at risk of disappearing, jeopardizing the lives of millions of coastal residents who rely on the sea. In fact in 1997 when he first moved here, Mr. Thai's house was still a kilometer away from the estuary covered by other houses, but after only 25 years the house is now highly prone and vulnerable to rising ocean waves. The sea has been intruded at an exponential rate. The house could collapse amidst any fierce storm. Lying in the house, he can even hear the sound of waves crashing and can feel the shaking. Mr. Thai has hardly had a sound night of sleep for a month now. Only the children of the Hamlet remain carefree. They have become accustomed to putting up temporary accommodations around the village. They are also used to skipping school early when studying in the classroom leaves them in as precarious a situation as their families home before the storm. On the other side of the west bank of Khamau Sea, Mr. Lao often paddles his canoe to the area where the family's old house off the coast has been eroded. What is left now only includes an old broken boat and the foundation of his family's house after the evacuation. Previously this mud flat was home to his family and dozens of households earning their livelihood through local fishing. The west coast used to be miles away from the sea, but after only about 15 years the sea drowned these houses. Mr. Lao's family was the last family to leave here when the waves already flooded the floor. Now only the old floors remain with concrete piles, remnants of the days of living at the stormy estuary. Mr. Lao misses the old house so dearly where his three children grew up, where his grandchildren were born and where he lived by the sea to support his family. The sea has sustained the fishermen offering them an abundance of fish and shrimp, but it is also engulfed houses in stormy weather. For a few years now, Mr. Lao has had to move with other families in the village to a resettlement area deep inland. In previous years, fishermen like him could go fishing all year long. But now the time left to go out to sea is only about four months. During this violent swell, Mr. Lao cannot go fishing and has nothing to do but hang out with the other fishermen in the hamlet. To deal with such unexpected leisure time, many people in the hamlet bring fishing gear to prepare and get ready for the next sea trip. Every rainy season, the sea of Kamau becomes less gentle. The waves roar day and night, encroaching the coast, washing away the coastal protected forests. Where the highest forest belt is only 70 meters, in some places only 30 to 40 meters. More seriously, in many places on the west coast, the forest belt is only about 30 meters. This used to be the land of mangrove forests growing in the wetlands and brackish water of Kamau Province and accounting for more than 70% of the region's mangrove forests in the Mekong Delta, which spanned more than 100,000 hectares in 2011, but has gradually been shrinking. More seriously, out of the 254 kilometers stretching from the east to the west coast of Kamau Province, 189 kilometers have been deteriorated by landslides, which can be attributed to the impacts of coastal currents and tides, especially big waves and high winds from the rise in Silam. According to the latest climate change scenario issued by the Ministry of Natural Resources and Environment, climate change is forecasted to impose a strong impact on people's lives in Kamau. In particular, by 2040, Kamau is expected to have more than 4,600 kilometers squared of land flooded from 1 to 1.2 meters under the 25 centimeter sea level rise scenario, accounting for 85.4% of total natural area of this locality. Rising water and land subsistence processes occur simultaneously, while environmental pollution and excessive rain also affect the main livelihood activities in Kamau water such as fishing and aquaculture. This not only affects the sustainability of the master plans of Kamau Province and the Mekong Delta, but also affects the food security of the country and the region. The tides keep rising day by day. Rises in sea level will continue to make many areas of coastland and headlands more vulnerable, coping and adapting to even a small change to the natural environment can create a big impact. Not only on nature, but on the humble people living on the strip of land at the end of Vietnam who are dealing every day with the waves and winds. There has always been a persistent inner strength among them, deeply rooted, rising up strongly on this land amidst the harshness of natural disasters. Today, on the west coast of Kamau, Mr. Tai brought his grandson back to the old mudlands to remind the children of the house where they were born, the trauma that the coastal people have experienced to understand the ferocity of nature and to learn to live with it. The sea is fierce but also full of tolerance. The sacred cape is still preserved by the mangrove trunks that have risen out of the old house, although it will take more time for them to take root and stand firmly on this turbulent shore.
