Vietnam SINKING PROOF:
/ The Mekong Delta provinces was 70 kilometers deep saltwater intrusion. According to the Institute of Water Resources South, from the mid to late March / 2012, salt water salinity 0.1 ‰ penetrated 70 kilometers deep in the Cuu Long River Delta provinces. /
/ Forest is dying, sea is marching into mainland. Coastal forest in the Mekong Delta is being narrowed while the sea is infiltrating deeply into the mainland. Mr. Tran Kim Chuong, head of the Natural Resources and Environment Department of Cu Lao Dung, said that the district’s An Thanh Nam commune is expanded by 50 hectares yearly towards the sea while An Thanh 1 commune loses 1,000 to 2,000sq.m of land per year because the sea encroachment. Meanwhile, in Bac Lieu province, the preventive forest has narrowed by nearly 10 percent in the last three years, to 4,600 hectares. With 56km of coast, this area of protective forest is not enough to prevent the sea from encroaching into the mainland.

Forest is dying, sea is marching into mainland
VietNamNet Bridge – Coastal forest in the Mekong Delta is being narrowed while the sea is infiltrating deeply into the mainland.

Coastal forest retreats
In mid-May, 2012, correspondents followed a group of experts of the Center for Preservation and Development of Water Resources to make a survey of mangrove forest and sea dikes in the Mekong Delta.
They visited Cu Lao Dung district, in Soc Trang province. This is the largest and the last islet of the Hau River. The islet fronts the East Sea in one side.
Mr. Tran Kim Chuong, head of the Natural Resources and Environment Department of Cu Lao Dung, said that the district’s An Thanh Nam commune is expanded by 50 hectares yearly towards the sea while An Thanh 1 commune loses 1,000 to 2,000sq.m of land per year because the sea encroachment.
An Thanh Nam is expanded to the sea because it has maintained 1,200 hectares of coastal preventive forest. Local people said that thousands of bats have appeared in the local forest. This is a good sign, showing environmental improvement.
Meanwhile, in Bac Lieu province, the preventive forest has narrowed by nearly 10 percent in the last three years, to 4,600 hectares. With 56km of coast, this area of protective forest is not enough to prevent the sea from encroaching into the mainland.
Nha Mat ward in Bac Lieu province was a preventive forest in the past. Today, this area has become a crowded residential area. Mr. Nguyen Kim Huynh, 49, in Nha Mat ward, pointed to a concrete dike and said that this sea die was broken several times by powerful waves.
Huynh said that in the season of northeast wind, sea waves are several meters high and the dike could not stand these waves. Since the coastal forest was destroyed, the sea has had less fish, the man said, adding that he could earn several USD a day from catching fish.
Dr. Duong Van Ni, lecturer of the Environment and Natural Resources of the Can Tho University, said that in this situation, preventive forest outside sea dikes will gradually disappear.
Ni explained that coastal forest is a closed ecological system, which can move forward and backward. The construction of concrete dikes has broken the living vessel and the way to move backward of forest.
The sea encroaches upon the mainland
Ganh Hao dike.
The Ganh Hao River, which separates Bac Lieu and Ca Mau provinces in southern Vietnam, is around 50km long. The river runs to the sea, making it become a busy fishing port.
Several decades ago, Ganh Hao was a wild area, covered by jungle. Nowadays, the forest has nearly disappeared.
Mr. Nguyen Van Be, from Ganh Hoa town, Bac Lieu province, who has lived here since the 70s, said that his home was removed several times because of landslides. “The entire hamlet 1 at the Ganh Hao estuary disappeared totally because of landslides. Landslides have become serious since 1997.”
After a fierce landslide, a concrete dike was built along the Ganh Hao River, which is called the shield to protect the town. Mr. Be said at present, the dike can defend his house but he was not sure about the future.
Be’s house is near the dike and he said that during the northeast wind season, waves were 1-2m higher than the dike.
In late 2011, the sea water rose high in Bac Lieu, which was said to be an abnormal phenomenon, and flooded the Ganh Hao fishing port, isolating hundreds of families.
According to the Bac Lieu Hydrometeorology Center, the highest flood tide measured at Ganh Hao estuary
Perhaps the time that people encroaching into the sea has ended. Dr. Le Anh Tuan from the Institute for Climate Change Research of the Can Tho University said that research works showed that the sea will continue rising in the future.
Impacts from climate change on the Mekong Delta are anticipated to be huge and they will be fiercer if hydro-power plants are built on the main stream of the Mekong River.
Upgrading sea dikes is considered an urgent task in the Mekong Delta to confront the rise of sea levels. In addition, planting preventive forest along the coast is very important, experts said.
Rural clean water - still much to do
Ben Tre has 65 km of the coast districts of Ba Tri, Binh Dai, Thanh Phu and is surrounded by four major rivers are Tien, Ba Lai, Ham Luong and Co Chien. In recent years, due to the impact of climate change from sea salt water should penetrate deeper into the land, with over two thirds of the province land salinization. 4% o salinity of the estuaries of about 60km, 1% o salinity almost covers the entire province.
Actually it was causing difficulties for production and people's lives. Moreover, according to the Center for Clean Water and Rural Environment, Ben Tre, only a few communes in Chau Thanh, Thanh Phu have groundwater at depths from 40 - 120m and 350 - 450m. Water quality is only temporary for daily use for measuring salinity from 0.35 to 0.8% o - beyond the standards of the Ministry of Health regulations (less than or equal to 0.3% o).

According to the Department of Agriculture and Rural Development (MARD), Ben Tre currently has 228,000 households with about 800,000 rural people affected by salt water, most concentrated in the districts of Ba Tri, Binh Dai, Thanh Phu , Giong Trom, Mo Cay Nam, Mo Cay North. Over the years, from the programs and projects of the province and other international organizations, the Center has focused on building 52 factories rural water supply with a total capacity of 870m3 / h, serving about 30,000 households. At the time of saline as in April every year, there are about 40% of plants were not affected by saltwater intrusion. Specifically, from 2010 onwards, the Center has put into operation and exploitation of some plants such as Water Factory Tan Hao (Giong Trom), capacity 40m3 / h, providing Long My Commune, Tan Loi Thạnh WTP An Ngai Chinese phrase, An Phu Trung (Ba Tri), Binh Thanh water plant capacity
20m3 / h for both Chau Binh upgrade and expand the Long Dinh Water Plant from 20m3 / h to 60m3 / h for the Long Hoa, Long Dinh, Phu Thuan Chau Hung (Binh Dai); Upgrade water plant Tan My (Ba Tri) from
165m3 / h to 330m3 / h, water supply for 15 villages and town of the district. Water plant in Thanh Phu is also upgrading and expanding investment, with a capacity of 60m3 / h to 120m3 / h, is completing expansion phase supply network for Hung commune, Quoi Dien, Binh Thanh District, town. Phu Duc Water Plant (Chau Thanh) are being constructed with a capacity of 50m3 / h serves Tien Thuy, Quoi Thanh, Tan Phu.
This year, the center also plans to deploy the water plant construction Yonghe capacity of 100m3 / h of water to meet the needs of Phuoc My Trung, Thanh Ngai, Phu My, Phu Son, betterments and Thuy Tien wide Water Plant (Chau Thanh), from
20m3 / h to 60m3 / h for Tien Long, Tien Thuy. Upgrade Water Plant Hung Franchise (Giong Trom), from 10m3 / h to 30m3 / h give Tan Thanh.
Along with the construction, upgrading factories, the Center has invested and built over 8,000 pipe supply reservoirs for poor households, poor beyond the scope of water supply plants; allocation of 2700 freshwater tanks for 2700 households of 36 communes policies in the province. What is remarkable is that organizations that manage and operate the plants are particularly interested in, the Center has operated a total of 49 extraction plants in Giong Trom District, Thanh Phu, Binh Dai, Ba Tri, European Thanh, Mo Cay Nam, Ho. Ben Tre with a total capacity of 1.000m3 / h, equivalent 24.000m3/ngay - night, serving more than 30,000 rural households. Under the plan, the period 2012-2015, the Centre urgently expand the water supply network for the construction of new rural communes, especially the sea Thanh Phuoc commune, Thoi Thuan, Thua Duc (Binh Dai), from The fresh water supply projects from the reservoir Ba Lai. WTP works Thanh Phuoc province has been approved, the Center is surveying, project investment. Expected plant capacity 120m3 / h will serve about 5,000 households in Thoi Thuan Commune, Thua Duc Thanh Phuoc. Initially, raw water pumping center has for over 300 households, and households in order to guide the engineering process with alum, chlorine or PAC bags before putting into use to ensure safety. According to DARD, although the advantage of using multiple sources of capital for construction and upgrading of some plants to gradually raise the living standards of rural people but capital is not much so far the rate of rural people water used by Qui 02 of the Ministry of Health standards reached only 34%.
Meanwhile, the situation of salinization is increasing every year, lasting, causing difficulties for people's daily life. So, to solve many pressing problems of rural water, PPC has directed the agricultural sector continue to ensure maximizing the capacity of existing plants to ensure good water quality. At the same time, promoting rural people more aware of drinking water for people to adapt to climate change conditions increasingly shown more clearly. The province has also agreed to advocate the construction of the plant raw water supply from Cho Lach District in Thanh Phu by DARD as an investor. But according to the Center, clean water programs and rural environmental hygiene for many years but there is much work to do but have not achieved positive goals. In part due to lack of funds, because every year from central funds to support only a few billion, just back from 2010 is about 15 billion. However, by 2020 the planned investment needs upgrading and building new water plant is estimated at 2,000 billion. So, Ben Tre is required by the Government, central ministries, the support of international organizations.
To operate small power plants are good in the dry season, the Danish government has approved funding for 12 Mekong delta provinces, including Ben Tre, each province three power generation systems using solar energy heaven. This model can operate the plants of small capacity. Lien Aid (Singapore) through the National Center for Water and Sanitation towards rural development funding and system model treatment technology for reverse osmosis water plant Phu Khanh (Thanh Phu ) to handle salt water. Oxfam also noted, considered in the financing of mobile systems can handle the water from polluted water due to floods, high tides, especially water treatment salt into fresh water supply for households in areas near river dunes, coastal areas. In addition, the Center also collaborates with many local solutions, different forms families to serve as movement of people invest their own containers, building tanks, pipes reservoirs. Also, experimental research and modeling applications, new solutions such as filtration of household organization Hemispheres (Singapore), water purification equipment using solar energy for desalination technology does not generate wastewater F.Cubed (Australia).
Soc Trang field the salt, rice death
(VOV) - Despite tough as the previous year, but so far, has done more acres of saltwater spring-summer and summer-autumn rice in the province soon dried up.
Unlike previous years, this year in Soc Trang province have appeared more season rains reduce salinity in the estuary, estuary, significant limitations salinity conditions in the locality. But in the last days of April and early May, the hot sun again, salt water began marching into the field of Soc Trang province, making it difficult for the production of her children.
Many hectares of paddy crop is in danger because of the salt
Anh Nguyen Tan Go, a farmer in Vinh Bien, Nga Nam district, said the summer test his family nearly 1 ha of summer rice cultivation. Stood paddy growing quite well but he did not hide his fears upcoming water shortage due to prolonged heat and salt water intrusion into the infield, "We are worried farmers, in the days to water River will diminish further, when he had no water to pump up. We expect local authorities to take measures to help farmers to pump water to land ".
Currently, in the Vinh Bien, Vinh Quoi (Nga Nam Town, Nga Nam district), salt water from the canal Bac Lieu Quan Lo - Phung Hiep penetrate deep into the sweet zone of the district, affecting more than 14,000 hectares of rice-summer collection.
According to Agriculture and Rural Development Department Nga Nam district, salinity measured at the crossroads town area up to 9.6 ‰ year, sometimes even higher. If in addition to salt water only 5 stages in the rivers spill into the district, the first 4 months of this year to 6 round attack salt water into the land make it difficult for agricultural production.
All nine culverts to prevent salt Nga Nam district was closed, but the difficulty is that many households in Bac Lieu province (bordering areas with Lieu Nga Nam district) brought salt water into canals for shrimp to salinity. Currently, large areas of rice-summer collection in Russian in the foot dry fields, but farmers can not pump water into the rivers, canals saline.
Local government and agriculture Nga Nam district are closely monitoring the evolution of salt water, and she recommended me to carefully consider the sowing of summer rice.
Mr. Nguyen Van Tien, deputy chairman of DPC, added: "We recommend that farmers need some water to the area early to pump water storage to prevent the Bac Lieu in the salty water will overflow into the Nga Nam. Recommendations relative water storage measures should be taken to produce the highest triumph. "
For the coastal district of Soc Trang province like Long Phu, Cu Lao Dung, Tran Vinh Chau and irrigation systems but fairly complete but state salt intrusion is threatening the spring-summer and summer-autumn rice in the districts this particular channel east of the district Tran Next Japan and some social end of the sweetness of the district such as Phu My Tu, My Thuan.
For township Dai Ngai, Long Phu district has salt water encroachment into the infield. At Vam Dai Ngai sometimes up to 3 ‰ salinity. This is a clue estuary should continue if saltwater intrusion it may cause salination of rice whole area Long Phu district and part of the district Tran. For irrigation of summer rice, one of the temporary measures are being implemented in Long Phu district is pumping about 2 ‰ salinity in rice research. At the Tan Thanh, Long Phu district, the authorities are taking advantage of mobilizing the field to pump water into the drain reserve are due to be closed to prevent saltwater.
According to Nguyen Thanh Truc, Chairman Tan Thanh: "I propose functional bodies running well the drain. When the salt water down, for water and salt water to rise again recommended closing the drain. Learning from Rice died last year, this year suggested that more care industry functions. "
Although not severe as the previous year, but by this time, salt water has also made several hectares of rice spring-summer and early autumn have withered Nga Nam district. If prolonged heat today and continue into the deep saline land, the Soc Trang province will have dozens of hectares of rice production shortage of fresh water and dried. /.
Soil erosion -- natural or human calamity?
Soil erosion has shrunk Chau Ma Island by 15-20 meters on each side every night, sweeping away five or six houses close to the bank
Numerous islanders in Vietnam’s Mekong Delta have lost their lives, relatives, houses, land and other belongings due to rampant soil erosion that has caused many islands to disappear.
Those who survive blame God for adding disasters to their miserable fate, but the problem has been partially caused by human beings.
Unbridled exploitation of sand in the two major rivers of the Mekong Delta -- the Tien and Hau rivers -- is counted as one of the factors leading to the calamity as it has created changes to the tidal flow, which had been stable for centuries.
Mechanical leveling of alluvial ground along the banks of rivers has also forced changes to the water flow, causing further erosion.
Disasters on islands
The family of Nguyen Thanh Liem, 84, which lives on Chau Ma Island in Hong Ngu District of Dong Thap Province is one example of victims of land erosion.
He lost his son, his house and all of his land. The disaster has caused his family to break up as each member has had to leave their homeland to work as hired laborers in different provinces.
The entire island of Chau Ma is three kilometers long and initially began to erode in the 1990s. It has now become an immense surface of water in the Tien River. His two-hectare piece of land fell to the bottom of the river overnight last year.
“Every night, the island shrunk by 15-20 meters on each side, sweeping away five or six houses close to the bank,” said Liem.
His son, Nguyen Van Khon, who was deputy chairman of the People’s Council of Hong Ngu District, was killed 20 years ago by the soil erosion.
“On the night of his death he was working late in his office when the water nymph came to take him away. His office building collapsed into the water. The guest house and State Treasury buildings of Hong Ngu fell on a night in 1992,” Liem recalled.
“When he was alive, he pursued his dream of going to school to gain knowledge and build construction sites to modify the tidal flow to prevent erosion. But he was finally killed by the problem he wanted to solve.
“After leaving the office, his wife took her three children to buy a house deep in the center of the island, but erosion has gradually approached. They have no place to move,” Liem added.
Formerly, Chau Ma Island and its 5,000 inhabitants belonged to Phu Trung Commune, but it has almost been eliminated and the commune was merged into Phu Thuan B of Hong Ngu District.

In similar cases to that of Chau Ma, other islands such as Tao, Beo, and Thuong Thoi Tien in the Mekong Delta have encountered increasing soil erosion, with Tao and Beo having totally disappeared. Sections of river banks have also faced threats of soil erosion.
Apart from damage caused by human being as sand exploiters, Ph.D Ha Quang Hai -- chief of the Environment Department of the Ho Chi Minh City National University -- noted that soil erosion is a natural and inevitable process during the steady and non-stop history of forming the earth’s crust.
“The Mekong Delta sits on a weak structure of land and thus it is easily affected by the complicated winding tidal flow of Tien and Hau rivers. It is a certain process in flood plains,” said Hai.
However, the scientist said he has paid attention to the recent abnormal rate of soil erosion in the Mekong Delta.
Every year, hundreds of hectares of land once used for cultivation in the region have disappeared, causing severe damage to houses, public infrastructure and crops in Can Tho, An Giang, Dong Thap, and Tien Giang.
Ph.D Nguyen Huu Chiem, chief of the Environment Department of Can Tho University, said local authorities should carry out comprehensive plans to survey, measure and map out the bottoms of rivers, as well as their tidal flows in different seasons.
This will provide a base to produce precise forecasts in the future, he said.
The Mekong Delta provinces was 70 kilometers deep saltwater intrusion
According to the Institute of Water Resources South, from the mid to late March / 2012, salt water salinity 0.1 ‰ penetrated 70 kilometers deep in the Cuu Long River Delta provinces.
Little Shop River, Cua Dai and Ham Luong seawater salinity 0.4 ‰ (crop damage) penetrate 50km deep, to the city of My Tho (Tien Giang), Tan Thach Commune (Chau Thanh District), My Hoa (Ba Tri District) of Ben Tre province. Also at the three river water salinity 0.1 ‰ salinity intrusion 70 km deep.
The Mekong Delta provinces have saltwater intrusion
On the Co Chien River, Cung Hau, salt water with salinity from 0.4 ‰ up to 55km deep penetration Duc My (Cang Long district, Tra Vinh). Salt water salinity 0.1 ‰ to penetrate deep 70km Long Thoi commune (Tieu Can district, Tra Vinh) and Trung Thanh Tay (Vung Liem district, Vinh Long).
Dinh An river, Tran, salt water salinity 0.4 ‰ to 60 km deep intrusion An Phu Tan (Tieu Can district, Tra Vinh) and Nhon My Commune (Sach District, Soc Trang province). Salt water salinity 0.1 ‰ penetrate deep Tra town 70km (Tra district, Vinh Long province) and Phu Huu Commune (Chau Thanh District, Hau Giang).
In Ca Mau, the Ong Doc River, Cai Lon, salt water salinity from 4-29 ‰ penetrate deep U Minh town 65km (U Minh district) and lavish Pomegranate (Vi Thanh Town, Hau Giang) . Salt water has high salinity (over 29 ‰), which appears on both rivers during the period from the date of 21-25/3.
Water Resources Institute of the South said that the salt water will overflow into a focal point of the channel in the Mekong Delta affects the pumping of water into the plowed field during summer-autumn rice sowing. Institute recommends that salinity affected provinces should actively placements season, plants and animals appropriate to minimize damage caused by salt water.
In particular, the provinces need to regularly check and close the drain when the large dams and mobilizing farmers to reinforce the dike line suspended by the canals, rivers and salt water to prevent overflow into the field for the rain to fall tillage sowing of summer rice crop up.
Landslides kill six in Kasese
Six more people have died in separate landslides in Kasese district.
This brings the number of landslide victims in the district to 11 over a period of seven months.
In October 2011, mudslides killed five children and destroyed several houses in the area.
The latest mudslides that hit Butalimuli village in the Rwenzori Mountains on Thursday night killed three children from the same family.
The tragedy occurred during a heavy overnight downpour.
The water-soaked soil on the steep Mahango slopes rolled downhill, burying Feridina Baluku Kyamukagha’s children.
By the time the family and neighbours woke up and tried to save Belivin Bwambale, 9, Constance Muhindo, 7 and Winfred Biira, 5, they were already dead.
Kyamukagha’s brother Mathias Masereka said the children were sleeping in the upper room when the wall collapsed, narrowly sparing their mother, baby brother and father, who were in the lower part of the house.
Elsewhere, a female resident of Katumba village, Kyalhumba sub-county, a man in Bibwe village, Muhokya sub-county and a nine-year-old girl of Nyakabingo village, Rukoki sub-county were also confirmed dead.
However, their identities could not be established.
The district environment officer, Augustine Kooli, warned that similar disasters were likely to reoccur as the rains continue in the steep mountainous areas.
“The soils have been weakened due to poor cultivation practices which have left most of the mountain areas bare,” Kooli said.
Mahango sub-county chairperson Stephen Muthekengwa said 23 houses had collapsed with dozens of people narrowly escaping death on the fateful night.
Kasese Woman MP Winfred Kiiza Bihande urged the Government to quickly help the affected families.
