摘要：Globally, wetlands are recognized as the most productive ecosystems due to sustaining a wide range of biodiversity and for providing goods and services to nearby communities. The study was carried out in three wetlands in Ethiopia; namely, Adele, Teneke and Haramaya. The data was collected from January 2016 to May 2016 in the villages which are in proximity to the wetlands to determine the degree of dependency on the wetland. Wetland physicochemical data was collected onsite using portable kits for the work. The study revealed that annual service rendered by the wetlands is 34956.62 in Ethiopian Birr. The biological oxygen demand, which is taken as an indicator for pollution was greater in all the sampling sites of Adele. The highest concentration (6.3 mg/L) was recorded at Adele 3(A3). The conservation practice designed by the local community initiative was low. From the five measures recommended, only one activity is done to conserve the wetland. The consumers' willingness to conserve services suggests that they are not willing to conserve the wetland. The study indicates that the socio-economic structure of the society is significant in their willingness to conserve and also to restore the wetlands. Educational level of the respondents is significantly affecting their willingness for conservation scheme.
