Bangladesh

Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting Bangladesh.

Vulnerability

Overall risks from climate-related impacts are evaluated based on the interaction of climate-related hazards (including hazardous events and trends) with the vulnerability of communities (susceptibility to harm and lack of capacity to adapt), and exposure of human and natural systems. Changes in both the climate system and socioeconomic processes -including adaptation and mitigation actions- are drivers of hazards, exposure, and vulnerability (IPCC Fifth Assessment Report, 2014).

This section provides a summary of key natural hazards and their associated socioeconomic impacts in a given country. And it allows quick evaluation of most vulnerable areas through the spatial comparison of natural hazard data with development data, thereby identifying exposed livelihoods and natural systems.

Natural Hazard Statistics

The charts provide overview of the most frequent natural disaster in a given country and understand the impacts of those disasters on human populations.

Natural Hazard / Development Nexus

This tool allows the overlay of different natural hazard maps with social economic datasets by sliding the bar horizontally, which provides a broad sense of vulnerable areas.

Key Vulnerabilities

  • Earthquakes: Bangladesh is located in a seismically active and high-risk region. The northern and eastern regions of the country are particularly susceptible to earthquakes.
  • Droughts: Seasonal droughts in Bangladesh most commonly affect the northwestern region, as it receives lower rainfall than the rest of the country. These droughts have a devastating impact on crops thereby also affecting the food security of subsistence farmers.
  • Floods: Floods and riverbank erosions affect some one million people annually in Bangladesh. Once every three to five years, up to two-thirds of Bangladesh is inundated by floods. Floods affect a greater population base than any other natural hazard in the country.
  • Cyclones: Sixty percent of the worldwide deaths caused by cyclones in the last 20 years occurred in Bangladesh. The cyclone that struck the coastal areas of Bangladesh in November 1970 caused over 300,000 deaths and US$ 2.5 billion worth of damage to property.

  • Defining and redefining the risk environment, entailing systematic and improved hazard analysis and vulnerability/community risk assessments, and risk treatment and ranking, including incorporation of climate change impacts.
  • Managing the risk environment, including achieving a good balance of risk reduction options, moving from generic hazard to risk specific programs, and mainstreaming risk reduction across sectors through advocacy, policy and planning reform, and capacity building.
  • Responding to the threats to the environment, including activating systems and mobilizing resources, utilizing vulnerability and risk databases for emergency response planning, and maintaining effective communications and early warning systems.
