Bangladesh - First Jamuna River Sustainable Management Project : Climate Change Technical Note (English)

Bangladesh is extremely vulnerable to the effects of climate change. The Global Climate Risk Index ranks Bangladesh as the world's seventh most affected country over the period 2000-2019. Rising temperatures leading to more intense and unpredictable rainfalls during the monsoon season and a higher probability of catastrophic cyclones are expected to result in increased tidal inundation. It is estimated that a one-meter rise in sea levels would submerge 18 percent of arable land in coastal areas. Recent studies estimate that by 2050 Bangladesh could have 13.3 million internal climate migrants. Additional rural-urban migration would have significant consequences for air and water pollution and unsustainable consumption of natural resources, while putting additional pressure on urban labor markets. Addressing climate risks is increasingly urgent to ensure sustainable economic development of the country.
