5m sea level rise, Vietnam can lose 16% of the area

If sea level rises by 5m, Vietnam could lose 16% of the area, along with more than 35% of the population and about 35% of the total GDP affected. Meanwhile, according to calculations, if the ice in the Greenland region melted, the world sea level would be 7m higher than it is today.

A study published by the World Bank (WB) has just named ' Impact when sea level rises in developing countries - comparative analysis' by author Susmita Dasgupta, Benoit Laplante, Craig Meisner, David Wheeler and Jianping Yan show that the Red River Delta and Mekong Delta regions are most affected if sea levels rise.

'Sea level rise of only 1 meter will affect about 10.8% of Vietnam's total population, especially in the Red River and Mekong River Delta'. - The team confirmed.

This study also shows that sea level rise due to global warming has the strongest impact on developing countries around the world.

Study to use satellite map with comparative parameters of 84 developing coastal countries to calculate the impact of sea level rise on people, economy, urban and agricultural areas career in 5 different regions in the world.

'When this happens, only scientific research can identify it,' said Susmita Dasgupta, senior economist and co-author of the study. But it is important that countries know if the sea level rise by 1 meter will affect what area will be submerged, how much damage to GDP, how much agricultural and urban land will be lost. ' .

According to the study, Egypt's Nile Delta will also be affected nearly as much as Vietnam, with 10.5% of the total population affected and 25% of the total area being submerged.

'There are a few countries that have preventive programs, but the pace of progress is slow. We hope the information in this study will be the driving force for faster action, ' Ms. Dasgupta said.
