-General use of water resources: Vietnam has about 2/3 of the total amount of water is flowing into the territory from the outside. The use of water upstream, the construction of irrigation, hydropower of the countries on the big River upstream (Red River, the Mekong River) will be a very great difficulties for us in the use of water resources and protect the environment. CLIMATE CHANGE will degrade water resources, while the water needs of the country are increased, increasing disagreements and conflict may have in general use of water resources.-Environmental/climate refugees (domestic and international) due to take place in or by disease and poverty. There is the warning that the climate refugee problem, not merely social, economic problems that could also be a political issue, the war.-Ecological security due to the perturbations of numerous HST, the encroachment of exotic organisms and genetically modified organisms.The impact of CLIMATE CHANGE to the infrastructureThe infrastructure here is understood as the construction works in all areas of life and production such as construction, energy, transportation, industry, agriculture, tourism, services. Characteristic of the object is relatively long time, centuries and can withstand direct impact and continuity of climate, weather, and CLIMATE CHANGE is now with the growing trend.CLIMATE CHANGE will affect the computer facilities, usefulness, load, endurance, safety of the designed works.So, the need of CLIMATE CHANGE impact assessment for each type of infrastructure in each specific local to have proper adaptation solutions is important.Source: http://moitruongviet.edu.vn/tac-dong-crab-bien-doi-when-hau-den-tu-Max Kane-va-far-http:////moitruongviet.edu.vn/tac-dong-cua-bien-doi-khi-hau-den-tu-nhien-va-xa-hoi/GS.TSKH, hoi. Zhang, optical presentation of the program of cooperation Vietnam-Sweden (SEMLA), 10/2015.III. EFFECTS OF CLIMATE CHANGE TO THE MEKONG DELTAIn Vietnam, for about 50 years, the average temperature has increased by about 0, 7oC, sea level has been rising by about 20 cm. El-Nino phenomenon, La Nina-drastic impact increasingly to Vietnam. Climate change (CLIMATE CHANGE) really did for the disasters, particularly typhoons, flooding, drought intensified. According to calculations, the average temperature in Vietnam could increase to 3oC and sea levels could rise 1 m by the year 2100. If the sea level rises 1 m, approximately 40 thousand km2 coastal plain of Vietnam will be flooded annually, of which 90% of the land area in the province in the MEKONG DELTA (according to the Ministry of natural resources and the environment).At present there are over 18 million people living in Vietnam Mekong Delta (MEKONG DELTA). Natural tragedy will huỹ ruined the MEKONG DELTA environment. According to the forecasts to 2030 about 45% of the area of the MEKONG DELTA face risk of salty. Most recently, drought, saltwater intrusion in the Mekong River Delta increasingly complicated happenings, directly affects the lives of people living around the region and threatened the food security of the country.The MEKONG DELTA is one of the most developed regions of Vietnam, located in the lower Mekong basin, amounting to about 5% of the whole area of the Mekong River basin. Have the system streams and rivers, canals, and beachfront grass ligament the sea's vast resources, the land is flat, fertile and are annual inning, abundant seafood resources with many ... Besides the advantages which naturally bring the MEKONG DELTA also must always face difficulties and restriction on the flow conditions and the resources, silted due to suffer the impact, no small challenge and immeasurable from upstream activities, climate change and sea level rise. The risk of shortages of water, the average flow per month total, smallest in the Cuu Long River Delta can be reduced to 3.5 billion m3 of water; The average flow of the smallest three months total in the cuu Long River Delta can reduce to 13 billion cubic meters of water. The average flow of the shallow season total in the cuu Long River Delta can reduce up to 30 billion cubic meters of water. Sources of fresh water shortage problems will impact negatively the utmost in every economic and social life. Particularly for agriculture and rural development, the lack of water resources is causing big losses in the difficulties the main issues as follows: lack of water for agricultural production, planting fruit trees and livelihoods; Lack of fresh water resources serves for aquaculture; According to the forecasts in the coming years, sea levels will rise high in a day, salt infiltration ability will be very large. Water flow upstream of decreasing traffic will not be enough to push saline, saline water will penetrate deep into the hinterland. On the issue of flooding, the average flow of the biggest one-month total in the cuu Long River Delta can rise to 3.6 billion m3 of water. The average flow of the flood season in total in the cuu Long River Delta can rise to 40 billion m3 of water. Flooding will increase in the Dong Thap Muoi region and the Long Xuyen Quadrangle, especially the region between two River and Hau River more serious. In addition to the cities/towns were inundated flood currently as Chau doc, Long xuyen, Cao Lanh, there will be more Permanent, Pigneau L
