study was conducted on the impact of climate variability on household water security and sustainablernlivelihoods in Shebel Berenta Woreda, East Gojam zone in the Amhara region. The objective is to explore andrnassess what real conditions characterize the area with regard to the water security status of the households andrntheir livelihoods coincided with their income levels. The study also aims at identifying causes of water insecurityrnfor the households, the extent to which climate variability and change affect livelihoods sustainability. The wordarnhas two broad agro climatic zones known as the Southeast Woinadega Teff (SWT) and the Abay Beshillo Basinrn(ABB) Livelihood zones. To achieve the objectives a household survey was carried out by purposefully selectingrnthree PAs in the woreda from the two livelihood zones based on their water access and availability. Samplernhouseholds were selected from each PA and wealth group. The data obtained through FGD, key informantrninterviews and questionnaire methods have been analyzed by the applications of modern computer softwarernmainly SPSS and MS Excel to process quantitative data and present in the form of cross tabulation, frequenciesrnand/or percentages and graphs. The study found that many of the households are at present under great pressurernof food and water insecurity dilemmas mainly due to variability of rainfall and recurrence drought episodes. Thernproblem varies in space and time and based on the households resilience or adaptive capacity. In ABB livelihoodrnzone, many households are in a state of low level of food and water security as compared to that of the midlandrnhouseholds, and are highly vulnerable due to their excessive dependence on rain fed agriculture, which itself is arnhighly vulnerable sector. The available water sources are highly seasonal and HHs are forced travel 5-10hrs per dayrnto collect water for home consumption and to water their livestock in the ABB Zone. Crop as well as livestockrndiversity is not common especially for the poor households, which is a clear manifestation of vulnerability. Fromrnthe sample poor households, for example, 67.8% do not have any livestock holding and a considerable number ofrnhouseholds harvest only one type of crop with less than 5 quintals annual yield. With regard to water access fromrnthe surveyed middle and better off wealth group households of the WSZ, 38.5% and 33.3% say that there is arncritical water problem for their household where as about 62.5 % and 66.7% respectively respond the absence ofrnany water shortage for them .Thus, intervention shall involve through: the development of ground waterrnresources in the midland livelihood zone as a mechanism of copping and mitigation to climate change related risksrnand vulnerability, and must also be considered from a livelihoods perspective. Up-to-date data on water sources,rnwater related conflicts, and facilities to market principally transportation and communication networks must bernkept for development planners and researchers. Thirdly, the geographic features and social settings of the arearnintegrating livelihood activities mainly farming, livestock rearing, and a combination of the two attracts furtherrnresearch. So that it is possible to clearly identify risk and vulnerability factors and effects across the transects.rnKey words: households, livelihood, resilience, Climate change,, seasonality, water security, Impact, sustainabilityrnand adaptation
