Mekong Leaders Agree to Improve Cooperation on River

Daniel Schearf for VOA in Hua Hin, Thailand

Leaders of Mekong River nations meeting in Thailand have agreed to improve cooperation on using river resources.

The agreement comes after a severe drought dropped the Southeast Asian river’s levels to a 50-year low, raising pressure on China to provide regular information on its upstream dams.

Prime ministers from Cambodia, Laos, Thailand and Vietnam Monday agreed that better cooperation is needed to balance the economic benefits from the Mekong River and protect the livelihoods of tens of millions of people.

Thai Prime Minister Abhisit Vejjajiva stressed the importance of joint responsibility in managing the river’s resources.

“And, such high level cooperation could not have come at a better time…

China asked to supply data about hydro-power dam on Mekong River

VNN news

Le Duc Trung, Chair of the Vietnam Mekong River National Committee, has confirmed that Vietnam was invited to visit China’s Jinghong Dam.

Trung said that Vietnam will join this trip, but they have not yet received a detailed plan from China.

According to Trung, during this trip, Vietnam will ask China to:

1/ provide Vietnam and other countries located downstream along the Mekong River with information on the technical parameters and operating mechanism of the Xiaowan Dam – one of the four biggest dams upstream on the Mekong River.

2/ provide and have exchanges with Vietnam about hydrometeorological data related to the Xiaowan Dam and other Chinese dams on the Mekong River

3/ strengthen cooperation and exchange of information on Mekong River dams with all affected countries.

According to the Vietnam Mekong River National Committee and the Vietnam Big Dam Association, China has built and operated four big dams upstream on the Mekong River (Manwan, Xiaowan, Daichaoshan and Jinghong). There is no detailed report on the impact of these dams on countries located downstream from the dams.

China asks Mekong states to visit dam

The Bangkok Post

Wants to counter claims that it’s causing drought

China has invited countries from the lower Mekong subregion to visit its Jinghong dam in a bid to counter claims that its poor water management is causing drought in downstream countries.

Kasemsun Chinnavaso, director-general of the Water Resources Department, said China had invited representatives from Cambodia, Laos, Vietnam and Thailand early this year to visit the Jinghong dam, one of four dams it operates along the Mekong River, but the trip was postponed due to cold weather.

The new visit is expected to take place this month.

“This is a very significant step for closer bilateral cooperation between China and members of the lower Mekong subregion for effective river management to deal with recent unusual drought and floods,” Mr Kasemsun said.

The downstream countries blame China’s dams for unusual flooding along the Mekong two years ago and for this year’s severe drought.

Thai PM asks China to help sort out Mekong problem

MCOT

BANGKOK, March 8 (TNA) – Thai Prime Minister Abhisit Vejjajiva on Monday asked China to determine whether dam construction in its reaches of the Mekong River is among the factors that may have led to the record-low water level downstream in the river, which is severely affecting not only Thailand, but other countries in the region, the Lao PDR, Cambodia and Vietnam.

The Thai prime minister discussed with Chinese Assistant Foreign Minister Hu Zhengyue regarding the severe drought conditions and the record-low water level in Mekong River.

Mr Abhisit has expressed concern over the problems and asked China to convene an expert meeting to establish the facts as to whether the record low level in the Mekong was caused by drought or by China’s dam construction as some critics have observed.

The information will pave the way for joint Mekong management through the existing regional mechanism, the Thai premier said. Thailand believes that China, which plays an active role in regional development, does not want to see downstream countries suffering from the problem.

Thai PM believes China not withholding Mekong River water intentionally

MCOT

BANGKOK, March 6 (TNA) — China has no intention to bring suffering to countries in the Mekong River basin by withholding water although the river has dropped to its lowest level in 50 years, Thai Prime Minister Abhisit Vejjajiva said Saturday.

Mr Abhisit said the cause of the current water shortage must be investigated, especially in northeastern Thailand, emphasising that it is too early to conclude that China should be blamed for not releasing water retained upstream.

The prime minister said he believed that China had no intention to bring difficulty to the Mekong Basin countries, and that if requested, China would definitely cooperate.

Drought will worsen as temperature rises to 43C

The Bangkok Post

A severe drought is beginning to take its toll on parts of the country as temperatures are expected to hit 43C this summer.

Cargo barges can no longer ply the Mekong River due to a drastic drop in water levels, and farmers in some areas have begun to fight among themselves over water supplies.

The weather bureau predicts the highest temperature this year to reach 43C.

The Chiang Rai Customs Office said river freight to and from China would come to a halt because the Mekong River had become too shallow.

The goods are now transported overland along the 2,000km-long R3A route which links Thailand with Xishuangbanna prefecture in Yunnan province of southern China via Laos.

The office said the route was busy with the number of trailer trucks carrying cargo containers jumping to 50 a day, from 50 a month a few months ago.

China’s dams killing Mekong

The Bangkok Post

Like most rivers in this country which are fast drying up under the scorching summer sun, the Mekong is no exception. This otherwise mighty river has shrunk substantially in size and its once forceful flow is now down to a trickle in many lower stretches of the river, to the extent that navigation has become impossible.

Although the drying up of the Mekong River in the dry season has become a normal phenomenon, the situation this year appears to be much worse than that in previous years. The impact has already been felt by people depending on the river for water, transport and food. The Irrigation Department of late has reported that the river in Loei, Nong Khai and Nakhon Phanom provinces has already reached critical levels even though the peak of the dry season is still a month away. Tour boat operators in Chiang Rai’s Chiang Saen district have suspended their services because the water level is too shallow for navigation. Fishermen have reported fewer catches prompting many of them to turn to other manual jobs to make a living.

Less rainfall as a result of climatic changes may be partly to blame. But non-governmental organisations which have been closely monitoring ecological changes in the Mekong River have been quick to point accusatory fingers at China. They blame China for storing up water, especially at the newly-completed Xiaowan hydro-electric dam, to generate electricity. That is just part of the sad story. The damming of the Mekong’s tributaries in Laos and northeastern Thailand, such as the Pak Moon dam, also contribute to less water flowing into the Mekong.

JAPAN: Fresh Aid to Mekong Signals Rivalry with China — Experts

By Catherine Makino for IPS

TOKYO, Nov 11 (IPS) – There is more to Prime Minister Yukio Hatoyama’s pledge last week to extend at least 500 billion yen (5.6 billion U.S. dollars) in fresh assistance to the Mekong region than meets the eye, or so observers think.

Japan’s underlying intentions toward the Asian economies, especially in the Mekong delta regions, have not changed significantly, said Tomohiko Taniguchi, a foreign policy analyst and professor at the prestigious Keio University.

What has changed is that there is now a sense of urgency and crisis among many Japanese bipartisan policy makers that the Mekong sub-region is going to be a “playground” for the Chinese, he said.

The strategy of the new government, which was swept into power in September’s landslide election, is to build the Asian community like the European Union, he added.

“Unless Japan and other like-minded democracies do the job, it will be carried out solely by their giant neighbor, the Peoples Republic of China,” said Taniguchi “But rarely will Japan state its true intention.”

A river becoming a road to ruin

From The Nation | Bangkok

China is constructing a series of eight dams on the upper half of the Mekong, where the river passes through the high gorges of Yunnan. These include the recently completed Xiowan Dam which, at 292 metres high, is the world’s tallest. Its storage capacity is equal to all of Southeast Asia’s reservoirs combined, the UN report said. The dams are needed to meet China’s rapacious energy demands.

Laos, meanwhile, has started construction on 23 dams on the Mekong and its tributaries, expected to be finished by 2010, the UN said. They will act as a means to spur development and lift the country from poverty. Cambodia and Vietnam also have ambitious dam-building plans.

Climate Change from 1960 to 2000 in the Lancang River Valley, China

From the International Mountain Society and published via the BioOne Online Journal

He Yunling and Zhang Yiping from The Chinese Academy of Sciences concluded from their investigation published in 2005…

This study investigated long-term climate change at 19 stations across the Lancang River from the north to the south. Over the observation period of 41 years, mean annual air temperature increased at the rate of 0.01°C/yr to 0.04°C/yr at 12 stations at the significance level ? = 0.01. Precipitation change in different areas was very different. Mean annual precipitation decreased from ?2.86mm/yr to ?5.29mm/yr at 3 stations, and mean annual precipitation increased from 5.77mm/yr and 7.44mm/yr at 2 stations, statistically significant at the significance level ? = 0.05.

On a seasonal basis, the climate change trend in air temperature was more significant in the dry season than in the rainy season, with precipitation showing converse behavior. On a spatial basis, the lower reaches of the Lancang River experienced much more severe climate change (temperature increase, precipitation decrease, and drought development) than the upper reaches in the past 41 years.

The data was analysed using Sen’s Slope – Minitab informs us that

Sen’s Slope is a nonparametric alternative for estimating a slope for a univariate time series. This approach involves computing slopes for all the pairs of ordinal time points and then using the median of these slopes as an estimate of the overall slope. Sen’s slope is insensitive to outliers and can be used to detect if there is a trend in the data.
