ABSTRACT

The study was conducted during the period from June to December 2013 to investigate the nature and impact of river erosion and to identify the indigenous adaptation practice to cope with the natural calamities. To perform these study two char villages (Radhanagar and Bashuria of Pingna union) were selected from Sarishabari upazila of Jamalpur district. A semi-structured questionnaire survey, key informant interview (KII) and field observations were carried out for data collection.

The study focused on the socio-demographic profile of the victims and the physical environmental conditions with a special attention to natural disasters of the region. The study found that, erosion was a great impact on livelihood, agriculture, environment and other sectors. Population displacement was a common phenomenon in the study area. This study revealed that, about 54 and 48% people loss 6 to 10 acres agricultural land in Radhanagar and Bashuria village, respectively. During the river erosion, 86 and 71% people took temporary migration and, 14 and 16% took permanent migration in Radhanagar and Bashuria villages.

Household’s ability to adapt with flood and river erosion depends on people’s socioeconomic and environmental conditions, such as education, income and occupation. The study also stated that along with organizational support, the people of the villages were to formulate and undertake various adaptation techniques in their own way. They used their indigenous knowledge to adapt through this diverse situation. Results found that almost 66% residents didn’t take any measures to purify drinking water. Finally, the study recommended to the policy planners and implementers for the future development of the river erosion victims in Bangladesh.

Key words: River erosion, adaptation techniques, livelihood, Jamuna river.
