“…This, in turn, leads to flooding. Hence, land use -land cover change and flooding considerably caused by urbanization and population growth, it will be momentously essential to estimate and comprehend the rate of land consumption (Irham et al 2022;Naikoo et al, 2020;Astuti et al, 2019;Lacher, 2019). Equation ( 5) was used to calculate the land consumption rate, which was employed as an index to quantify how quickly an urban region expanded spatially in proportion to its population (Sharma, Pandey, and Nathawat 2012).…”

Land use land cover change (LULCC) is an imperative factor in global environmental change parallel with population growth and global warming. In many developing countries dynamics of land use land cover is significantly increasing, the main factors can be mentioned are prompt economic, and population growth along with globalization. The study area, Awash River Basin (ARB) faces several major challenges, including land degradation, depletion of water resources, rapid population growth, and urbanization. This paper aimed at analyzing the dynamics and correlation of land-use land cover change and population growth with respect to flood hazards in the study area. GIS and RS geospatial techniques was applied to develop a comprehensive supervised land use classification maps and to analyze LULCC disparities. The overall accuracy for the year 1990, 2000, 2010 and 2020 classification were 94, 97.6, 99 and 96, whereas the kappa coefficients for the same year were 0.92, 0.97, 0.99 and 0.95 respectively. In general, within three decades of time (1990 to 2020) agricultural land declined by 1.3%, in contrary, bare land is declined significantly by 50%, deep water bodies shows reduction by 43%, forest coverage registered positive value of 13.7%, the Wetland class has shown a significant increase of 191%, whereas urban area has been significantly increased to 121% of change rate. Results of Pearson correlation analysis demonstrated negative r value for bare land, deep water bodies, agricultural land, and forest coverage (-0.75, -0.49, -0.28, & -0.25 correspondingly). In contrary, urban area and wetland are correlated positively along with population growth (0.94 & 0.89) respectively. Moreover, estimated land consumption rate (LCR) is 0.29, 0.28, 0.26, and 0.34 in a year of 1990, 2000, 2010, and 2020 respectively. Henceforth, increment of population alongside with built-up area has potentially caused modifications of land use land cover and regularly results in flooding. Considering sustainable nature-based solution to mitigate spontaneous rapid land use change and flood impacts is invaluable.
