Changes in the regional climate have already been observed, says the UN environment programme assessment report on the region. “The number of hot days and nights is growing, sea level has risen 20cm in the last 50 years and by 2050, millions of its citizens will be at increased risk from regular and extreme climatic events such as floods, droughts, storm surges, and tropical storms,” it says.

Ho Chi Minh city (HCM) has been ranked as one of the 10 cities in the world most vulnerable to climate change. Parts have always flooded, but a 26cm sea level rise projected by the UN to hit by 2050 could swamp nearly 70% of the whole urban area costing its economy billions of dollars,” says the Asian Development Bank in a recent report.

"The Mekong and it's people are in trouble" : article from this weekend's Phnom Penh Post.
Pollution and dams are up, fish stocks are down.

And why large hydro projects are not as green as you would think. In fact, mega-dams are not green at all :

Dismal news for the Mekong and the people who live on it, with this pessimist report on fish conservation from the experts, in the face of Laos' plans to carry on with dam constructions without heed to environmental destruction.The dams are going ahead regardless.There has not been sufficient time for adequate assessment of the consequences on fish stocks, or how best to mitigate the damage.
The race for short-term profit is on and dam the consequences. :facepalm:

Mekong Dams Fish Passages ‘Problematic,’ Experts Say
by Aisha Down | November 19, 2016

As Laos forges ahead with plans to build 134 dams on the Mekong River and its tributaries over the next two decades, international experts have cast doubt on its proposals for averting devastation for the waterway’s estimated 850 species of fish.

Gathered at a conference in Vientiane this past week, the experts assessed—and largely dismissed—the feasibility of preserving the Mekong ecosystem through the construction of “fish passages” around the dams, a system of artificial streams and troughs that aim to let fish migrate from one side to the other...

A study on the environmental impact of Laos' latest Mekong dam proposal shows several fish species are particularly at risk, including the Mekong giant catfish. The Pak Beng dam will be situated in northern Laos, but all dams built upstream from Cambodia will result in some sort of environmental alteration downstream. One of the biggest concerns about damming the main Mekong river is the effect on fish spawning and the fish population.

World’s Largest Freshwater Fish Under Threat From Planned Dam
by Aisha Down | February 23, 2017

The world’s largest freshwater fish may go extinct as a result of the environmental impact of the newest dam proposed on the Mekong, according to documents released ahead of a consultation that began on Wednesday.

The Mekong giant catfish, which can grow up to 3 meters long and 300 kg in weight, is critically endangered with their populations decimated by overfishing, dams and habitat destruction, according to the environmental organization WWF.

The building of a massive 912-megawatt dam in their habitat would put them under further strain, warned a technical review posted to the website of the Mekong River Commission (MRC) ahead of a forum on Pak Beng dam in northern Laos.

“The Mekong giant catfish…is likely to be seriously and negatively impacted by the Pak Beng hydropower project…eventually or possibly leading to extinction,” the review says.

Further impacts on fisheries were unclear due to a lack of data on fish migrations, adds the document, which summarizes environmental impact assessments submitted by the dam’s developer, China Datang Overseas Investment Company. The summary was presented on Wednesday in Vientiane...

They always choose the Mekong catfish as if it were the sole victim when in fact many other species, imminently more edible, are migratory and will be more sorely missed by the rural poor. More aquaculture is needed not only because of the damned dams but because of pollution.

Point is that while the media will pick out one example like the Mekong giant catfish for simplicity, the impact on the other species of Mekong fish is also being studied. The text says they have identified 58 migratory species that are particularly threatened.
Most people can't be arsed reading the studies, and are not interested in the details, but that doesn't mean they don't exist.

Handsome beast though.

these fishes eat all shit, if the shit is good (organic shit) then the fish is good, not a tasty fish but it will solve part of the protein problem
