The prime objective of this study is to assess the socio-economic impact of wetlands in the study area; the secondary objective is to establish the condition of the wetlands and to propose remedial measures. Primary and secondary data were used for this study. As primary data, we employed direct observation, questionnaire survey and group discussion. As secondary data, we utilized statistical data from Navithanveli DS Division, previous researches and general ecological works. In Navithenveli DS Division, inhabitants are benefitted by wetlands in many ways. Paddycultivations, vegetable cultivation, small-scale fishing, biodiversity, groundwater recharge, gardening, Tule mat industry and water for domestic usages. Indiscriminate activities of inhabitants, unplanned and improper infrastructure have caused many challenges for the wetlands in the study area. Many remedial measures have been recommended to conserve the wetlands in the study area.
