Abstract
The undesirable conversion of land from natural to human-induced landscape has been increasing in this century because of many interrelated factors thereby increasing the frequency and intensity of flooding. Data collection techniques employed in this study were questionnaires, key informant interviews, group discussions, and personal observation. Sample sizes of 310 households were contacted for the questionnaire survey using systematic sampling techniques while purposive sampling technique was applied for identifying participants of group discussions and interviews. Landsat imageries of 1991, 2001, 2011, and 2020 were utilized for studying land cover dynamics and the classification was done by using a supervised maximum likelihood classifier algorithm. The results of the study demonstrate that in the past three decades (1991-2020), vegetation and grassland severely diminished aggravating the severity of flooding on livelihoods of the local communities. Thus, the results obtained from the image reveal that the settlement and cultivation land of the study area has been by 202.15 and 640.22 ha respectively. The collapse of grass and vegetation has been minted mainly because of the absence of integrated land use planning in the country. The results of the study also show that standing crops, livetraps production, grazing land, housing conditions, sources of drinking water and school attendance have been adversely affected by flooding events leading to the disturbance of livelihoods. Therefore, the study recommended the development of integrated land use planning and locally applied flood control measures.
