Agriculture in Bangladesh Bangladesh is an agrarian country. About 20% GDP comes from agriculture. Few years ago, it was a food deficit country but at present it stands as a food sufficient country. On the other hand, it is a densely populated country. Main food is rice. Also it is most vulnerable in Climate Change issues.
Bangladesh Agricultural Development Corporation (BADC) was established on 16 October 1961 with the mandate to supply the most vital agricultural inputs like seed, fertilizer and irrigation and to provide services to the farmers.

BADC is mandated to monitor two important Climate hazards: • Groundwater table monitoring; • Saline water intrusion monitoring Collected data is used to make information to give message to the people, researcher and also to the Government through publication of booklet, bulletin and 3D-DEM map.

Rec ecomme ommend ndation tions Early forecasting of rainfall is needed to increase crop productivity as well as food security; Forecasting may be location and time specific; Need the accurate early forecasting and should be available in the website of BMD; Forecasting should be user friendly. 10/20/2015 18
