About the Cover

The haor basin at northeast Bangladesh covers almost one fifth of its total land area, produces about 20 percent of country’s total staple food grain (rice) and supports livelihood for twenty million people. However, the areas are regularly affected by flood hits with enormous loss of crops, fodders, and other food commodities, and earning sources that make the people live therein vulnerable. Proper attention is not paid yet to explain the disaster occurs in the areas and overcome from the hazard risks with a holistic model. Therefore, the aim of the study is to explain the progression of vulnerability and hazards situation due to flood shocks in haor areas with a popular conceptual framework like the Pressure and Release (PAR) model. Important drivers of the root causes, dynamic pressures and unsafe conditions responsible to progress the vulnerability (Pressure model) are identified through collecting both secondary and primary sources of data from published, unpublished and grey literatures, consulting with various categories of stakeholders, and focus group discussion meeting with flood victim’s farmers. The possible determinants (relief drivers) towards the progression of safety and disaster mitigation as a whole are pinpointed in the Release model which can be utilized in the Disaster Risk Reduction (DRR) or Management (DRM) programmes.
