Abstract

This paper examines the nature and causes of September 2004 hazardous flood that affected the dry and drought prone southwestern region of Bangladesh. It also examines human perception of this new hazard and their methods of adjustments to its negative impacts. Field research for this study includes personal interviews of 453 victim families living in four thanas (lowest administrative units) in Jessore and Satkhira districts of southwestern Bangladesh. Findings of the study suggest that all victim respondents viewed this flood event as a natural hazard, which has caused severe damage to standing crops, fish ponds, permanent trees and homesteads, and deteriorated human health and sanitation conditions. Its long-term impacts on fish farming, soil quality degradation, as well as changing land use/land coverage are also noteworthy but yet to be adequately explored. Both perceived and scientific causes of this flood event include high rainfall for a week before the flood, unusual movement of low pressure system into the affected area, cloudy weather and low evaporation, siltation of the regional riverbeds, and rolling back of the Ganges River water through the Ichamati and Bhagirati rivers. These factors also caused hazardous flooding at the same time in the Ichamati and Bhagirati Rivers and their floodplains in the West Bengal province of India. To release the over flow of flood water inside India, the Indian border patrol breached the Ichamati river embankment in several places along Satkhira and Jessore international border which had aggravated the flood situation in the study area.
