The study assessed the association between rainfall variability and cereal output in Gozamen Woreda. It employed mean, standard deviation, the coefficient of variation and precipitation concentration index measures in analyzing the variation of rainfall over time. Correlation analysis was used to establish the association between inter-seasonal rainfall variability on each of the six major cereals output for the last ten years (2005–2014). Rainfall data analysis revealed a general decreasing of spring, summer, and annual rains, while autumn rainfall showed increasing trend. “Teff” registered more or less constant performance. Sorghum and “engido” exhibited declining performance, however maize and wheat had an increasing performance. Teff and barley negatively correlated with summer rainfall whereas maize and sorghum revealed a strong positive correlation with spring rainfall. “Engido” recorded negative correlation with autumn rainfall. From the result it is suggested that having recognized the physical potentials and demands, efforts should be made in areas of irrigation, traditional soil fertility maintaining practices. General environmental resources, conservation works should be done to realize sustainable development in the cereal production sector in particular and overall efforts of the inhabitants of the site in general.
