nr 2-4

This paper presents the findings of the socio-economic impact of household-level water harvesting technology. Before water harvesting was introduced, onions were not grown in the area due to lack of seedlings. Thus onion seedlings were grown on 100 m2 plots using water from the ponds in the dry season, then sold or planted under rainfed conditions during the rainy season. The results obtained show that the average net income from onion seedlings was 155 US$ per 100 m2 plot, while those from bulb onions grown rainfed in the field was 1848 US$ per ha, making the contribution to farmer incomes by onions alone about 2003 US$ per year which is higher than from rainfed teff and wheat combined.

Since the trends of adverse climate change and integrated urban water management have continued in the twenty-first century, governments and other institutions seek reliable predictions as water resource requirements arise. Although uncertainty is never cut off from the need for a probabilistic movement, through current developments in science and the technology of hydrological modeling on urban water management analysis, researchers can improve the ability to create realistic scenarios that will benefit the water sector it adapts to these changes. Model studies on the combined effects of climate change and the water sector have found that the change can be significant, depending on scenarios and the assumptions of climate change, as well as the degree of urban development. In this work, conceptual analysis of urban water management has been applied to several scenarios of climate change in order to obtain new insights and uncertainties.
