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.


To address the critical issue of climate change and its impacts on the environment and society, the Government of Bangladesh (GOB), with active support from multilateral development agencies has taken several creditable initiatives placing emphasis on adaptation measures targeted at its key priority sectors. The country ratified the Paris Agreement in September 2016 and has recently established two innovative funds: Bangladesh Climate Change Trust Fund (BCCTF), which are from the Government’s own budget; and the Bangladesh Climate Change Resilient Fund (BCCRF) with the support of development partners. Its priority sectors include agriculture, disaster management, coastal zone, infrastructure, urban planning, LULUCF, and ecosystem. As a result, it prioritized adaptation actions such as early warning system improvement, research and knowledge management, and ecosystem conservation.

Adaptation Options for Key Sectors

  • Development and dissemination of climate-resilient crop varieties and cropping systems for water-logging and salinity-affected coastal areas
  • Cultivation of vegetable crops in floating gardens and raised beds
  • Research and dissemination of drought-tolerant crop varieties; better storage mechanisms, and crop diversification
  • Improve knowledge and agricultural extension services
  • Sugar crops and other high value crops (HVC) improvement for adverse climate conditions through biotechnology
  • Agronomic manipulations such as shifting planting dates, using short duration crop cultivars
  • Modernization of existing irrigation schemes and demand management aimed at optimizing physical and economic efficiency in use of water resources and recycled water in water-stressed areas
  • Protection of groundwater resources and water catchment areas
  • Rainwater harvesting, creation of water reservoir, low cost filter in salinity affected areas
  • Increasing surface water storage and restoring natural water courses
  • Better irrigation water management to reduce mosquito breeding sites; improved diseases/vector surveillance and monitoring; education, training & awareness campaign on public health issues
  • Improved housing and living condition in climate vulnerable zones
  • Livelihood protection in ecologically fragile areas and protection of vulnerable socio-economic groups
  • Monitoring of internal and external migration and providing support for rehabilitation
  • Improving the education and work skills of migrants and financing of resettlement costs and rehabilitation
  • Construction of Multi-purpose Cyclone Shelter Centres for people and of raised platforms for livestock
  • Livelihood support and diversification to the coastal community
  • Flood protection coastal defense structure
  • Integrated project with promoting micro-finance in the vulnerable coastal areas; involvement of private sectors in the coastal areas through promoting micro-enterprise development

Gaps and Needs

  • Research the linkages between climate change, poverty, health, and vulnerability in order to ascertain how the resilience of the most vulnerable households may be improved
  • Analyze the impacts of climate change on Bangladesh’s macro-economy as well as key sectors
  • Model the likely hydrological impacts of climate change in the Ganges-Brahmaputra-Meghna system in order to assess future system discharges and river levels to feed into flood protection embankment measures
  • Improve climate change modeling scenarios for Bangladesh by applying methodologies at the regional and national levels
  • Create a Centre for Research and Knowledge Management on Climate Change to ensure that Bangladesh has access to the most current ideas and technologies available globally.
  • Enhanced efforts to disseminate forecast and meteorological data into information that can be translated into action at the local level.
  • Strengthening of efforts to raise public awareness and reach remote inaccessible areas through better communication systems, especially during times of extreme events.
  • Mainstreaming seismic risk awareness, mitigation, and reduction into the country’s core disaster management agenda and strategy.
  • Addressing existing knowledge gaps about climate change across sectors by mainstreaming climate change in development planning and implementation.
  • Although Bangladesh is participating in a multi-country project focused on mainstreaming gender considerations into climate change policy, it would appear that there is room to more significantly address the gender-based implications of future climatic changes.
  • Revise all government policies to ensure they consider climate change and its impacts.
  • Build the capacity of key government ministries and agencies to move forward on climate change adaptation
  • Improve the capacity of the government to undertake international and regional negotiations on climate change
  • Build the capacity of government, civil society, and the private sector on carbon financing
  • Build the capacity for education and training of environmental refugees to ease migration to other countries and integration into new societies
  • Because the country is in the very early stages of mainstreaming adaptation into their plans and strategies, specific capacity-development efforts would perhaps provide useful skills for application in this endeavor.
  • To better inform disaster management response and for sub-national planning, improved baseline field data collection, analysis and dissemination is required. Coupled with the unpredictability of coarse GCMs, it becomes imperative to have fine-scale data to support decision making in agriculture, water, energy, and disaster management.
  • There is need for data collection and analysis on various aspects of socio-economic vulnerability and resilience to climate change and other neglected sectors like health and manufacturing.
  • A centralized climate change database, which includes hydro-meteorological data, forecasts and warnings and also archives, needs to be developed.
