Abstract

Climate change has become a distressful event throughout the world in recent years. Long term rainfall and temperature variations are one of the main determinants of climate variability of one’s area. The frequency and severity of climate related shocks has increased in many parts of Ethiopia and are likely to continue with increasing trend in global warming. The aim of this study is to determine trends of variation in temperature and rainfall at Wuchale station in South Wollo Zone of Amhara regional state. Monthly rainfall and temperature record data was obtained from National Meteorological Agency for the period of 1986–2018. Mann-Kendall's test and Sen’s slope estimator were used to detect the trend and magnitude of changes, respectively. The results revealed that a significant declining trend of annual rainfall by the rate of 108.86mm and a significant increasing trend of maximum temperature by the rate of 0.2°C per decade was observed. However, non-significant decreasing trend of belg rainfall by 16mm and minimum temperature by 0.1°C per decade and increasing trend of kiremt rainfall by the rate of 40mm per decade was observed over the study period. The coefficient of variation ranged from 25.64 to 60.29, indicates moderate to high rainfall variability and precipitation concentration index ranged from 11.77 to 20.66, indicates moderate to strong distribution of rainfall in the study area. Therefore, development planners should develop and provide high-value crop varieties that resist uncertain rainfall during crop maturation period for accelerating adaptive processes and adopt short maturing crop varieties that can escape early season droughts and be able to mature earlier than the existing varieties.
