Vietnam’s lowlands to go under with climate change, bank report says

By Nantiya Tangwisutijit

When it comes to climate change, Vietnam’s Ho Chi Minh City is one of the world’s 10 most vulnerable cities.

As a result, around 70 per cent of its urban area may experience severe flooding in coming decades, according to a recent Asian Development Bank report.

The bank’s assessment is based on the United Nations’ projections of a 26-centimetre sea level rise by 2050.

Local authorities are taking the threat seriously, recently announcing flood-prevention measures of almost $US7 billion ($9 billion) over the next five years.

But the southern economic powerhouse, formerly Saigon and one of the fastest growing and most polluted cities in the country, is not the only Vietnamese centre at risk.

About 60 per cent of the country’s urban areas are a mere 1.5 metres above sea level and extreme climate events are increasing and widespread.

Will China save its last undammed river?

By Nantiya Tangwisutijit

In a remote corner of southwestern China, close to the Myanmar border, the towering Nu River gorge narrows to a frothy boil of rushing water, its powerful flow creating swirling eddies.

Thrown across the river from one rock face to the other hangs a flimsy suspension bridge. “No entrance” reads a sign on its locked and rusting gate. “For construction only.”

The abandoned bridge is the sole hint here of a lengthy environmental battle that may be nearing its end. For more than a decade, activists have fought a state-owned hydropower company’s plans to build giant dams on the Nu, the last natural river in China. Now, dam opponents say they scent victory.

Energy evolution

By Nantiya Tangwisutijit

Growing awareness of the impact of air pollution and global warming have been driving more investments in energy from renewable sources and moving green energy to the top of many government policy agendas.

In Southeast Asia, finding the right energy mix is a major challenge as countries strive to ensure that economic growth and environmental protection are compatible.

“The challenge faced by developing countries is balancing the cost of electricity and conservation of the environment,” Dr Maximus Johnity Ongkili, Minister of Energy, Green Technology and Water of Malaysia, said at Sustainable Energy & Technology Asia (SETA) 2016 held in Bangkok late last month.

Holding back the sun: Thailand, solar energy and the “base load myth”

By Nantiya Tangwisutijit

Thailand’s Energy policymakers recently announced plans to allow the private sector more access to promote solar power in the Kingdom. But restricting the program to just 100 MW of roof-top installations runs counter to emerging advice from within and experience from abroad, that solar power, and renewables generally are the way forward— not the large, unnecessary energy projects at home and in neighboring countries now driving Thailand’s energy policy.

At the core of this transition is debunking the myth of what’s known as base load: managing that minimal amount of power that is needed 24 hours a day to meet demand. Since electricity demand fluctuates hourly, with peak production in the afternoon when offices, air conditioners, and factories are in full operation, versus the wee hours of the morning when things are more cool and quiet, some power plants run all day long and others just supplement supply when electricity needs rise. Traditional fossil fuel plants have longtime been advanced to service this base load, and Thailand is no different. But techniques in demand management and the ability of solar in particular to meet the high demands during the day can reduce the need for these plants.

Vietnam needs clearer windpower laws: experts

By Nantiya Tangwisutijit

These were among the petitions related to administrative procedures that were raised at a validation workshop held in HCM City last week.

The aim of the workshop was to create more opportunities for further wind power.

The Validation Workshop on “Wind Power Investment Guidelines” was co-hosted by the Deutsche Gesellschaft fur Inter-nationale Zusammenarbeit (GIZ) GmbH in Vietnam and the General Directorate of Energy (GDE) under the Ministry of Industry and Trade (MOIT) in Vietnam.

Aurelien Agut, a GIZ consultant, said that interest to invest in small wind turbines was strong, but there were no clear regulations on the import of small turbines as well as on relevant procedures.

China’s Sudden Dam Water Releases Killing Wildlife in Lower Mekong River Basin

By Nantiya Tangwisutijit

It’s not just humans but also animals downstream who are affected every time water is released from Chinese dams into the Mekong River.
“The survival rate of baby birds has dropped to less than 60% over the past three years, as their nests lie on the riverfront and the water level of the Mekong is so unpredictable,” lamented the administrator of a Facebook page devoted to bird lovers.
