“…The results of future LULC could have many impacts on water resources in the NRB. As reported by Mechal et al (2022), the expansion of bare land could highly increase the discharge and decrease infiltration due to the higher curve number. It could also increase floods occurrence due to peak discharges .…”

Understanding land use / land cover (LULC) dynamic is of great importance to sustainable development in Africa where deforestation is a common problem. This study aimed to assess the historical and future dynamics of LULC in the Nakambé River Basin. Landsat images were used to determine LULC dynamics for the years 1990, 2005 and 2020 using Random Forest classification system in Google Earth Engine while the predicted LULC of 2050 was simulated using the Markov Chain and Multi-Layer-Perceptron neural network in Land Change Modeler. The findings showed significant changes in LULC patterns. From 1990 to 2020, woodland and shrubland decreased by -45% and -68% respectively while water body, cropland and bare land/built-up increased by 233%, 51%, and 75%, correspondingly. From 2020 to 2050, the results revealed that under the Business-as-usual scenario, bare land/built-up and water bodies could continue to increase by 99% and 1% respectively. However, cropland, shrubland, and woodland could decrease by -32.61%, -33.91%, and -46.86%, respectively. Under the afforestation scenario, the contrary of Business-as-usual could occur. While woodland, shrubland, and cropland would increase by 22.24%, 51.57%, and 18.13%, correspondingly, between 2020 and 2050, the area covered by water bodies and bare land/built-up will decrease by -6.16% and -39.04%, respectively. The results of this research give an insight into past and future LULC dynamics in the Nakambé River Basin and suggest the need to strengthen the policies and actions for better land management in the region.

“…Area (km In a similar research conducted by [115] on LULC change of the watershed of Lake Ziway for the period between 1985 and 2020 depicted an increase in cultivated land from 2,598.07 km 2 to 3,588.68 km 2 . Similarly, settlement increased from 365.00 km 2 in 1985 to 1,007.4 km 2 in 2020.…”

“…Eighty-nine percent of the total watershed areas consist of < 30% slopes, and the remaining > 30% slopes (steep to very steep hills and mountains). Thus, the watershed of Lake Ziway is characterized by rugged terrain and geological and structural complexities in which the principal features in the rift margin are dominated by chains of mountains, step faults, horst-graben structures and river channels [115].…”

Morphological study of lakes defines the sensitivity of their watershed. Moreover, it plays important role in safeguarding the lake’s ecosystem services through proper planning and utilization of the lakes’ resources. In the last few decades, the morphology of lakes in Ethiopian and Kenyan Rift (EKR) valley are experiencing contradicting morphological changes. Being in the same system, some are shrinking and others are expanding beyond their natural boundaries. The objective of this review is to shed light on the trends in spatio-temporal water level fluctuation and their contributing factors for lakes to the academia and decision makers. Peer reviewed article journals, conference proceedings, thesis, and book chapters collected from online sources and supplied by authors on request formed a database of 346 documents where 226 are critically assessed. The review indicated that lakes in Ethiopian rift are shrinking and expanding, while Kenyan lakes are expanding. The en-dorheic lakes suffered the most fluctuations due to anthropogenic factors at the expense of loss of forest and woodlands in their watershed. While the lakes’ water quality related to the morphological changes are given less attention, the predicted 12 m drop of Lake Turkana due to projects in the Omo catchment did not materialize.
