Freshwater under stress as acidity rises, scientists say

Friday, 12 January 2018 16:49 GMT

The first manifestation of freshwater acidification could be poor water quality due to a bacteria known for producing toxins

By Thin Lei Win

ROME, Jan 12 (Thomson Reuters Foundation) – Some freshwater ecosystems are acidifying rapidly as carbon dioxide emissions rise, according to research by German scientists, raising fears over fish stocks and water quality.

Only 1 percent of the world’s water is freshwater, but 40 percent of all fish are found there. Tiếp tục đọc “Freshwater under stress as acidity rises, scientists say”

Groundwater in the Mekong River Basin

3.11. Vietnam

• Salinization of groundwater in the coastal area

• Ammonium contamination in groundwater

• Groundwater level drops in Hanoi (-1 m/yr, total 30 m drop), Ho Chi Minh City (total 30 m), and in many other places in the Mekong River Basin; groundwater levels also decreased greatly.

• Land subsidence in Hanoi because of over-extraction

• High and increasing amount of arsenic in groundwater

Lives Behind Hydropower Dams

Published on Oct 19, 2017

There are more than 3,000 rivers in Vietnam, provide resources to feed millions of people and bring livelihoods to hundreds of communities. When the rivers change, fishermen and farmers are the first to be affected. By September 2013, more than 800 hydropower projects were planned, more than 250 hydropower projects operated, and more than 200 hydropower projects under construction. By 2013, due to only 21 hydropower projects in 12 provinces, more than 300,000 people were displaced and resettled. How are their lives now…? Tiếp tục đọc “Lives Behind Hydropower Dams”

The world is facing a global sand crisis

September 7, 2017 9.22pm BST

theconversation_When people picture sand spread across idyllic beaches and endless deserts, they understandably think of it as an infinite resource. But as we discuss in a just-published perspective in the journal Science, over-exploitation of global supplies of sand is damaging the environment, endangering communities, causing shortages and promoting violent conflict.

Skyrocketing demand, combined with unfettered mining to meet it, is creating the perfect recipe for shortages. Plentiful evidence strongly suggests that sand is becoming increasingly scarce in many regions. For example, in Vietnam domestic demand for sand exceeds the country’s total reserves. If this mismatch continues, the country may run out of construction sand by 2020, according to recent statements from the country’s Ministry of Construction.

Vietnam seeks solutions for “smart water use”

Last update 07:20 | 07/09/2017

VietNamNet Bridge – Environmental experts say HCMC needs to find solutions to smart water use, an important part of the plan to develop a smart city.

HCMC is now under pressure as demand for clean water is increasing while Sai Gon and Dong Nai rivers, the main sources of raw water for the city, are getting more polluted because of the increased number of industrial production workshops and animal farms.

The water supply plants, which have total clean water production capacity of 2.4 million cubic meters per day in HCMC, sometimes have to stop using raw water from Sai Gon and Dong Nai rivers because of the high salinity. Tiếp tục đọc “Vietnam seeks solutions for “smart water use””

Thirsty world must wake up to looming water crisis, expert says

We are really facing a global crisis… More than one-third of humanity is water-stressed every year or season, while drought crises are on the rise from California to EthiopiaBy Megan Rowling

STOCKHOLM, Aug 24 (Thomson Reuters Foundation) – The world needs to use water more efficiently rather than exhausting invisible underground supplies and blindly exporting “virtual water” to avert a global crisis that would undermine food and energy systems, a leading expert warned.

More than one-third of humanity is water-stressed every year or season, while drought crises are on the rise from California to Ethiopia as the planet warms, said Fred Boltz, who leads The Rockefeller Foundation’s work on science and environment.

Can technology help Bangladesh end mass arsenic poisoning?

Monday, 28 August 2017 06:00 GMT

An estimated 5 percent of deaths in Bangladesh are attributable to drinking water with high levels of arsenic, researchers sayBy Thin Lei Win

BANGKOK, Aug 28 (Thomson Reuters Foundation) – Almost a quarter of a century after public health experts discovered mass public poisoning in Bangladesh caused by water contaminated with arsenic, the government is planning a new push to end the scourge, while researchers are designing an app to find safe sites for new wells.

About 20 million Bangladeshis, or one in eight, have been drinking water with arsenic levels higher than the government’s limit of 50 microgrammes (μg) per litre, said Kazi Matin Uddin Ahmed, geology department chair at the University of Dhaka.

SOC TRANG, Vietnam: With a flashy gold watch and a chunky matching ring, Tang Van Cuol looks a far cry from the average Vietnamese farmer as he slings back a shot of rice wine and boasts about his projected earnings.

After years scratching a living growing rice and onions or farming ducks, the 54-year-old says his life was transformed in 2000 – by shrimp.
