Study region: Awash River Basin, Ethiopia
Study focus: Many river basins in sub-Saharan Africa have become vulnerable due to the impact from climate change, weak governance and high levels of poverty. One of the primary concerns is the elevated salinity and the degradation of water quality in the Awash River. Located in the Great Rift Valley in Ethiopia, the Awash River has unique hydrochemistry due to water-rock interactions. However, in recent years, increasing anthropogenic activities including the discharge from saline Lake Beseka into the Awash River has caused some concern. This study used an Integrated Catchment Model to simulate chloride concentration in the Awash River Basin by taking both natural and anthropogenic sources of salinity into consideration. Future scenarios of climate change and Lake Beseka discharge were examined to assess the impact to the river water quality.
New hydrologic insights: Results show that Lake Beseka has made significant contribution to the rise of the salinity in the Awash River. If the trend of human interference (e.g. increased irrigation and unregulated water transfer) continues, the river downstream of Lake Beseka could see Cl increases up to 200 % in the near future (2006–2030). The modeling results are essential for generating long term plans for proper utilization of water resources especially in the region where the resources and the economic capacity to meet the water demand is lacking.

Ethiopia’s agriculture is dominated by small-scale rain-fed production in combinations of natural and manmade factors have resulted in serious poverty. Irrigation farming is increasing been used as a strategy in Ethiopia. However, lack of consensus on the role of the irrigation sector on the welfare of smallholder farmers and pitfalls in impact study methodologies resulted in mixed findings. This study evaluated the impact of Awash irrigation on the welfare of rural smallholder farmers. Two-stage stratified sampling technique employed to select sample households. Cross-sectional household level data from a survey of 315; 165 irrigation users and 151 non-users smallholder farmers in Asiyta district, Ethiopia used for the analysis. This study employed endogenous switching regression model to control for endogeneity problems associated with adoption decision. Accordingly, the correlation coefficient result proved that the existence of self-selection and endogeneity. Results indicated, irrigation users’ per capita consumption expenditure and income were 16 percent and 35 percent, respectively, higher compared to non-irrigation-users significantly. Endogenous switching regression model further identified amount of own land cultivated, education status, number of extension contact, livestock holding, nearest market distance, access to non-farm job and nearest canal distance significantly determine irrigation participation. The study concluded that Awash irrigation is one of the viable solutions to improve the welfare of smallholder farmers in the study area. Therefore, governmental and non-governmental organization should promote, improve and expand Awash irrigation in all areas of the Woreda in particular and irrigation agriculture in general.
