“…The basin is already subject to water stress, with higher water demand than supply. For instance, a study by [4] estimated an average annual runoff of 4640 MCM (million cubic meter) while the average annual demand is 4670 MCM. The basin is subject to high intra-annual variability, with dry season water shortage recognized as a challenge for various activities such as irrigation and domestic water supply by the Awash Basin Authority [5].…”

Rapid growth of agriculture, industries and urbanization within the Awash basin, Ethiopia, as well as population growth is placing increasing demands on the basin’s water resources. In a basin known for high climate variability involving droughts and floods, climate change will likely intensify the existing challenges. To quantify the potential impact of climate change on water availability of the Awash basin in different seasons we have used three climate models from Coupled Models Inter-comparison Project phase 5 (CMIP5) and for three future periods (2006–2030, 2031–2055, and 2056–2080). The models were selected based on their performance in capturing historical precipitation characteristics. The baseline period used for comparison is 1981–2005. The future water availability was estimated as the difference between precipitation and potential evapotranspiration projections using the representative concentration pathway (RCP8.5) emission scenarios after the climate change signals from the climate models are transferred to the observed data. The projections for the future three periods show an increase in water deficiency in all seasons and for parts of the basin, due to a projected increase in temperature and decrease in precipitation. This decrease in water availability will increase water stress in the basin, further threatening water security for different sectors, which are currently increasing their investments in the basin such as irrigation. This calls for an enhanced water management strategy that is inclusive of all sectors that considers the equity for different users.

“…The hydrological water balance analysis of the Lake Tana Basin in Ethiopia indicated that base flow is an important component of the total discharge within the study area that contributes more than the surface runoff [18]. Radar rainfall data is useful in distributed hydrologic studies and was used as data input in the SWAT for application in flood analysis and prediction [19,20], and in addressing model response to extreme weather events and improving water resources distribution [21].…”

The soil and water assessment tool (SWAT) is a well-known hydrological modeling tool that has been applied in various hydrologic and environmental simulations. A total of 206 studies over a 15-year period (2005–2019) were identified from various peer-reviewed scientific journals listed on the SWAT website database, which is supported by the Centre for Agricultural and Rural Development (CARD). These studies were categorized into five areas, namely applications considering: water resources and streamflow, erosion and sedimentation, land-use management and agricultural-related contexts, climate-change contexts, and model parameterization and dataset inputs. Water resources studies were applied to understand hydrological processes and responses in various river basins. Land-use and agriculture-related context studies mainly analyzed impacts and mitigation measures on the environment and provided insights into better environmental management. Erosion and sedimentation studies using the SWAT model were done to quantify sediment yield and evaluate soil conservation measures. Climate-change context studies mainly demonstrated streamflow sensitivity to weather changes. The model parameterization studies highlighted parameter selection in streamflow analysis, model improvements, and basin scale calibrations. Dataset inputs mainly compared simulations with rain-gauge and global rainfall data sources. The challenges and advantages of the SWAT model’s applications, which range from data availability and prediction uncertainties to the model’s capability in various applications, are highlighted. Discussions on considerations for future simulations such as data sharing, and potential for better future analysis are also highlighted. Increased efforts in local data availability and a multidimensional approach in future simulations are recommended.

Competing Water Resource Demands in Ethiopia’s Federal System: Infancy of the Law toward Integrated Management

The Federal Democratic Republic of Ethiopia Constitution confines the power of regional states over water to administration of watercourse that flows within their respective territories. Various proclamations introduce an integrated approach to water resources management through the application of proper and integrated master planning. To this end, a new institutional framework is established through the creation of Basins" Development Authority at national level. The previously established Basin High Councils and Authorities were implementing integrated water management within their respective basins and the powers and obligations of the basin based high councils and authorities are transferred to the newly established National Basin High Council and Basins Development Authority. Some adjustments are necessary due to federalism and issues related to the constitutional framework of water resources that have been overlooked. When the Water Resources Management Proclamation and other water laws are read together with the various provisions of the FRDE Constitution, they lack clarity save the power of the federal government to enact framework legislation over water resources within states" territories. Works undertaken by the federal profit-oriented public enterprises transforming water into an economic good on the lands that are administered by the regional states is an area of on-going controversy. I argue that regional states should claim their constitutional right to levy and collect land use fee from profit making federal public enterprises that are engaged in transforming water into economic good within the framework of integrated water resources management system.
