Abstract

Haor is a well-known wetland feature in Bangladesh because of its dynamic ecosystem which is changeable with the seasonal variation. The majority people of the community are critically dependent on the haor. This paper attempts to analyse the provisioning ecosystem services of Aral Haor of Sylhet District, their changes and why the changes occurred during the last 30 years since 1990 to 2020 through community assessment. The papers argues that the community based approach integrates the local people to reveal the actual scenario of the livelihood dependency on the provision ecosystem services as they are the main user of the provisioning services. Thus the primary data were collected through observation, FGD, Community Mapping and interview with experts. The study found that community the service providing area of the Aral haor have not been changed in mentionable level over the 30 years, however the shape of the haor have been changed slightly due to high sedimentation. Along with rice cultivation during dry season, natural irrigation, fishing and bird nesting were most important to provisoing services to the community which have been changes due to both natural and anthropogenic activities. The study concludes that even having importance of the Aral hoar, not any measurer has been taken by local authority to conserve the Aral hoar ecosystem services those are very vital for the livelihood of the thousands of community people living nearby.
