Bangladesh along with its neighbouring India and Pakistan could see extreme increase in heat and humidity, which may significantly affect workability and liveability, according to a global report.
The McKinsey Global Institute (MG) launched the report on Wednesday that also said the three countries could face increased likelihood of lethal heat waves than the rest of Asia by 2050.
The report titled 'Climate risk and response in Asia' categorised Bangladesh, India, and Pakistan as parts of the Frontier Asia.
These rapidly urbanising economies have historically seen low levels of regional integration and have a diverse global base of trading partners and investors, the report observed.
"For example, by 2050, Frontier Asia could face increased likelihood of lethal heat waves than the rest of Asia," the MGI said, adding "We estimate that by 2050, between 500 million and 700 million people in Frontier Asia could live in regions that have an annual probability of a lethal heat wave of about 20 per cent."
The report also estimated that by 2050, in an average year 7.0 to 13.0 per cent of the gross domestic product (GDP) could be at risk as a result.
The report estimated that there is high risk probability in Bangladesh's liveability and workability as growing number of population may be exposed to lethal heat waves.
According to the report, lethal heat waves are defined as three-day events during which the average daily maximum wet-bulb temperature exceeds the survivability threshold for a healthy human resting in the shade.
Bangladesh's water stress risk will decrease in the coming days, the report said.
The term 'water stress' is used to indicate when demand for water is greater than the amount of water available at a certain period in time, and also when water is of sub-standard quality and this restricts its usage.
While different parts of Asia are affected differently, countries with lower levels of per capita GDP are probably most at risk from the impacts of climate change, the report mentioned.
