dc.description.abstractWetlands provide multiple ecosystem services such as water and water quality storage and regulation, providing unique habitats for flora and fauna, and regulating micro-climate conditions. Wetland conversion to settlement, agricultural use and industrial development are anon stopping practice in periurban area and becomes a treats of wetland. This research examined the effects of anthropogenic factors on a wetland ecosystem in Suluta Oromia region Ethiopia. Mixed approaches such as key informant interviews, focus group discussion and household survey (396 respondents) were employed to collect relevant data. A three year’s satellite image (1986, 2000, and 2020) analysis was also made to understand the trend of land use land cover change in the area. The LULC imagery data were checked accuracy assessment and kappa statics, which is 85.71 and 0.878 percent, respectively. The LULC rate of change of sululta from an initial year to final (1986 to 2020) that is, both wetland land and vegetated land were decreased by 843 ha (18 percent), and 1704 ha (37 percent) respectively. While Settlement, bare land and cultivated lands increased by 1935 ha 42 percent, 488 ha 11 percent and 124 ha 3 percent respectively. This indicates that the LULC of settlement, bare land and cultivated lands were increased at the cost of wetland and forest class. The past 34 years satellite image analysis reveals that the current situation of sululta wetland is characterized by highly degraded and depleted because of population dynamics and settlement expansions. The researcher suggests the administrations should consider these anthropogenic activities.en_US
