Bangkok, Jakarta, Manila and Yangon are among the other cities in the region that are projected to be affected.
The report, titled “Turn Down the Heat: Climate Extremes, RegionalImpacts and the Case for Resilience”, analyses the risks the regionfaces when the earth warms by 2 degrees Celsius, said Anjali Acharya,Environmental Team Leader of the WB Vietnam.
It said thatSoutheast Asian countries, including Vietnam, are particularlyvulnerable to sea-level rises, increases in heat extremes and tropicalcyclones, ocean warming and acidification.
The three river deltasof the Mekong, Irrawaddy and Chao Phraya – all with significant landareas less than 2 metres above sea level – are particularly at risk.
Agriculture, aquaculture, fisheries and tourism are the most exposed to climate change in these deltas.
Accordingly, a sea-level rise of 30cm, which could occur as early as2040, could result in a 12 percent loss of the Mekong Delta’s riceproduction. The area produces around 50 percent of Vietnam’s totalagricultural output and contributes significantly to the country’s riceexports.
The report forecasts that one of the biggest impacts inVietnam will be flooding in urban areas caused by sea intrusion in theMekong Delta.
The report was prepared for the World Bank by the Potsdam Institute for Climate Impact Research and Climate Analytics.
It follows the Bank’s first report, “Turn Down the Heat: Why a 4°C Warmer World Must be Avoided”, released in November 2012.-VNA
