Being one of five risky stormy areas, Vietnam is warned of suffering from the worst influences of calamity at present and in the future.
About 12 to 15 millions people might be lost their land because of climate changing.
According to the considering of UNO, Vietnam is one of five nations having the riskness of climate changing.
The spell of disasters haven’t followed the normal rules any more, currently, they often happen unexpectedly , bring about serious losses and damages for people. The nation centre of hydrometeology told that, this year, storms on Oriental sea maybe have influence to our country much and early.
People said that, all of research projects also confirm Vietnam is one of countries will be suffered from the strongest effect of climate changing, the phenomenon of sea level rising.
Follow the results of survey, within 40-50 years recently, the average of temperature per year of Vietnam has increased about 0.5 – 0.7 C degree, the sea level raising has been higher about 20cm. For the country has over 3200 km length of seaside, lies directly with oriental sea and being in tropical area, annually, Vietnam has been suffered at least 8-10 terrible storms.
Because of influence of climate changing, the phenomenon of flood-tide in 20 to 30 years ago was met with very hardly in Vietnam but recently, it often occurs complicatedly in the centre of central part of Vietnam, the Mekong river delta and Hochiminh city.
At present, scientists are fllowing, estimating 3 scenariuos of climate changing in Vietnam, includes: the sea level increases 70 cm; 1- 1,5m; 3m.
If according to the least scenario that the sea level increased 70cm, 10% of the Mekong river delta would be flooded with water. Besides, over 80% area of Mekong river delta and 30% area of Red river delta is only higher than the level sea about 2-2.5 m. And if followed the scencario that the sea level increases 3m, all of area of red river and Mekong river delta would be flooded.
The sea level higher will influence strongly to almost of aspect, firstly, to agriculture. Up to now, 75%of Vietnamese are living, working on agricultural land. If this one flooded, it would influence to15% people, is equivalent about 12- 15 millions people. Besides, the sea level increasing also effects to traffic, infrastructure, construction and environment.
Over 1 million km square area, over 3000 islands, many low areas near sea have been suffered from strong flooding in rain season. And suffering drought in dry season. Climate changing just makes the situation above more seriously.
Maybe 10% rate of land will be deeply flooded, salted, difficlulties in irrigation…
The sea level increasing also leads to the risk for construction near the seaside like the dykes of sea, line of communications, ports, factories, urban areas near the sea…
