Ho Chi Minh City is forecast to be one of the Southeast Asian cities most heavily affected by global warming, said the World Bank (WB) in Vietnam at a ceremony to announce its latest scientific report on June 20.
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, Regional Impacts and the Case for Resilience”, analyses the risks the region faces when the earth warms by 2 degrees Celsius, said Anjali Acharya, Environmental Team Leader of the WB Vietnam.
It said that Southeast Asian countries, including Vietnam, are particularly vulnerable to sea-level rises, increases in heat extremes and tropical cyclones, ocean warming and acidification.
The three river deltas of the Mekong, Irrawaddy and Chao Phraya – all with significant land areas 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 as 2040, could result in a 12 percent loss of the Mekong Delta’s rice production. The area produces around 50 percent of Vietnam’s total agricultural output and contributes significantly to the country’s rice exports.
The report forecasts that one of the biggest impacts in Vietnam will be flooding in urban areas caused by sea intrusion in the Mekong 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
