Climate change is a critical issue in Bangladesh. [1] as the country is one of the most vulnerable to the effects of climate change. [2] [3] In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. [4]
Rice production was particular affected, decreasing from 0.3 million tons to 0.1 million tons from 2008 to 2010. If the sea levels rise as predicted in a "moderate" climate scenario, Bangladesh is predicted to produce 0.2 million fewer crops. This number is predicted to be doubled for a "severe" climate scenario.
This corresponds to reaching 1.5 °C (2.7 °F) and 2 °C (3.6 °F) thresholds under that scenario: earlier research suggested that for maize, this would increase risks for multiple simultaneous breadbasket failures (yield loss of 10% or more) from 6% under the late-20th century climate to 40% and 54%, respectively.

The flood originated from the major rivers flowing into the Jamuna, (the lower stream of the Brahmaputra River), Meghna, Padma, and Ganges basins, following continuous rainfall that began in June and lasted until September. [1] [2] [3] It reportedly affected 32–45 out of a total of 64 districts, including Dhaka, the capital of Bangladesh. [3] [4]
Climate change has forced many people in Bangladesh living in rural areas to migrate to cities that has caused a sharp rise in the slum population of Dhaka. [8] As Bangladesh is only less than 20 feet above sea level, there are fears and concerns that by the end of the 21st century, more than a quarter of the country will be inundated and 15 million people will be displaced due to sea level ...
Agriculture is the largest employment sector in Bangladesh, making up 14.2 percent of Bangladesh's GDP in 2017 and employing about 42.7 percent of the workforce. [1] As of the financial year 2022 to 2023, the agricultural sector contributed to more than 12% of GDP. [2]
[3]: 1508 While total food production to date had been increasing, climate risks to agriculture and food security are expected to accelerate after 1.5 °C (2.7 °F) is exceeded. [3]: 1490 These risks will be regionally uneven, as food security is expected to improve in some countries or even country sub-regions, while declining in others.
Paddy field in rural Bangladesh. Rice production in Bangladesh plays a critical role in the nation's economy, affecting various sectors and socioeconomic factors. As the primary crop and staple food, rice is central to agricultural production, employment, and nutritional needs. It is a major contributor to Bangladesh’s national income.
