The saline intrusion in the Mekong Delta region during this year’s dry season would occur earlier and be worse than previous years, warned the Department of Water Resources Management under the Ministry of Natural Resources and Environment.

The level of saltwater intrusion may be approximately at the level of 2015-2016, which saw historic salinity and drought in the region.

This forecast was based on the data of water levels in the upper Mekong River’s reservoirs, the water resources of the Mekong River, especially the capacity of Cambodia’s Tonle Sap Lake, and the tides in the downstream area.

According to the data, the capacity of reservoirs in the upper Mekong River was estimated at 65 billion cu.m but by the end of September, the total capacity of reservoirs just reached nearly 70 percent.

At Cambodia’s Kratie station, in the first half of the dry season which is from November 2021 to January 2022, the average flow will be only about 5,600 cu.m per second, 20 percent lower than the same period in 2020-2021, but still higher than the years 2015-2016 and 2019-2020 by 26 percent and 40 percent, respectively.

In the second half of the dry season from February to May 2022, average flow at the station will be at 3,100cu.m per second, 10 percent lower than the same period in 2021 and equivalent to 2016, but about 15 percent higher than in 2020.

Regarding the water source in Tonle Sap Lake – a decisive factor in the regulation of water in the Mekong River Delta – the highest water volume forecast in 2021 is about 28-30 billion cu.m, which was 17-19 billion cu.m lower than the average capacity for many years and 1-2.5 billion cu.m of 2020.

In the dry season, tides from November to December this year will be higher than the average peak tide level for many years but from January to March 2022, the peak level will decrease gradually to the average levels of many years.

In 2022, there will be three high tides, from January 2 to 4, from January 31 to February 3, and from March 1 to 6, in which the first high tide is the largest in the dry season.

Meanwhile, the southwest monsoon that starts at the beginning of the dry season is a factor pushing saline intrusion deep into the canal system in the Cửu Long Delta provinces.

According to the Department of Water Resources Management, the saline intrusion in this dry season would affect 210,000ha of rice, orchards and rice-shrimp combination fields of the region.

Specifically, in the peak time, saltwater intrusion will likely affect 60,000ha of rice in the coastal provinces in the region, 11,900ha of which is in Tien Giang provice, 12,000ha of Ben Tre province, 15,000ha of Tra Vinh and 20,000ha of Soc Trang.

For fruit growing areas, the saline intrusion will affect nearly 43,300 ha; in which, Long An is 3,100ha, Tien Giang 21,800ha, Ben Tre 16,000ha and Soc Trang 3,400ha.

The saltwater will cause damage to 107,400ha of rice-shrimp combination fields in Kien Giang, Cà Mau, Soc Trang and Bac Lieu.

It was still quite early to accurately forecast saline intrusion in the dry season because the water source to the Mekong Delta depended greatly on the flow from upstream of the Mekong River including rain and water storage capacity of upstream reservoirs, the department said.

However, the possibility of small floods and low flows in the first months of the dry season may cause early saltwater intrusion, so the department recommends localities which are likely to be affected by saline intrusion must prepare irrigation solutions and production plans to minimise damage to agricultural production.

For the fruit growing areas, the farmers should store fresh water at maximum capacity in canals and ponds.

Provinces of Long An, Ben Tre, Tien Giang, Tra Vinh, Soc Trang, Bac Lieu and Kien Giang were recommended to complete the sowing of 400,000ha of winter-spring rice crop by October to avoid drought and salinity.

At the same time, the provinces must dredge the canal system to store fresh water and gradually close the sluices from the sea to the upstream from November.

Ben Tre province particularly may face difficulties in fresh water sources in this dry season because of incomplete water source control infrastructure so it should dig more ponds and lakes to store water.

The localities that are not directly affected by saline intrusion, should still prepare preventive measures for drought and water shortage due to insufficient rainfall and low water resources from upstream, the department said./.

Netflix denies purchase of phimmoi domain name

Published

on

Vietnamese users were surprised when they were redirected to Netflix.com when they tried to access phimmoi.net, a website that provides pirated movies.

Netflix denies purchase of phimmoi domain name

When typing or copying the URL of phimmoi.net on Facebook, the social network’s function of previewing content also gave images of Netflix.

It’s unclear why the users of phimmoi, an unlicensed website, were redirected to a provider of copyrighted films. Phimmoi was listed among the top 20 websites with the highest number of visits in Vietnam, about 60-100 million a month. Netflix only provides copyrighted products, to 150,000 users in the country.

In late August, the investigation agency of the HCM City Police filed charges in a criminal case over copyright infringement related to phimmoi.net.

Investigators found that since 2014, one man in Lam Dong province has been operating a website showing movies for free on the internet. He hired two individuals with high IT qualifications in Dong Nai province to develop, administer and operate the website.

The team copied, exploited, used, broadcasted and disseminated movie products to the public without the consent of copyright holders. Phimmoi was also engaged in illegally advertising products and services on copyrighted films in order to gain illicit profits, which were large amounts of money.

This is the first criminal prosecution case against a website providing pirated movies in Vietnam. After phimmoi.net was blocked, the owner of the website continued providing services with other domain names, such as Phimmoiz.net, Phimmoizz.net, iphimmoi.net or ephimmoi.net most recently, maintaining illegal activities.

The information about redirection to Netflix.com caused a rumor hat Netflix had bought the phimmoi.net domain name.

However, a spokesman for Netflix, contacted by VietNamNet, denied this. “No business of Netflix has bought the phimmoi.net’s domain name,” the spokesman said.

On November 30, it was impossible to access phimmoi.net, even with a VPN. However, when typing the URL of phimmoi.net on Facebook, one still could see the information about Netflix’s website on previewed links.

In related news, in mid-November, Netflix announced the launch of free Netflix package reserved for Vietnamese users. Vietnam is the first market in Asia and one of a few markets in the world where Netflix is offering a free package.

This service package is specifically offered to Android users. Users need to be over 18 years old and have never had Netflix accounts to be eligible. They just need to register via phone or email.

Vietnam has yet to receive signal from NanoDragon satellite

Published

on

Two out of nine satellites have yet to receive signal from the earth station 22 days after they were launched into orbit, said Deputy General Director of the Vietnam National Space Centre (VNSC) Le Xuan Huy.

Gần 1 tháng phóng lên quỹ đạo, chưa thu được tín hiệu vệ tinh NanoDragon

NanoDragon satellite is developed by a group of scientists from the Vietnam Space Center (VNSC).

They are ARICA test satellite developed by Aoyama Gakuin University of Japan and Vietnam’s NanoDragon satellite.

Studied, designed and manufactured in Vietnam, NanoDragon was successfully launched into outer space at a height of 560km from the Uchinoura Space Centre in Japan’s Kagoshima prefecture on November 9.

Before the launch, NanoDragon underwent four rounds of safety inspection by the Japan Aerospace Exploration Agency (JAXA) with the strictest standards and important environment, shock and functional tests. It also passed rounds of examination in Vietnam and was sent to Japan for launching under JAXA’s plan on August 6.

All tests in Japan were closely monitored by its developer VNSC, the Kyushu Institute of Technology, JAXA, High-Reliability Engineering and Components Corporation (HIREC) and MEISEI – partner of VNSC in Japan and supplier of test equipment for NanoDragon.

VNSC also discussed eventualities that could happen to NanoDragon and sought measures with MEISEI and JAXA, Huy said, adding that VNSC’s engineers are actively seeking signal from the satellite./.
