    Investigating the impact of Climate Variability on Crop: In Case of Wag Himera, North and South Wello Zones in Amhara Region
    (Addis Ababa University, 2024-02) Ayele Tadele; Hamere Yohannes (PhD)
    Climate variability like temparture and rainfall is a common characteristic in Ethiopia and it exceedingly affects agricultureparticularly in the northenparts of the country where rainfall is relatively scarce. Hence, understanding the spatio-temporal variability of rainfall is indispensable for planning mitigation measures during high and low rainfall times. This study examined the spatio-temporal variability and trends of rainfall in the WagHimera, North and South Wello Zones in Amhara region Ethiopia. The coefficient of variation (CV) was employed to analyzerainfall variability while Sen’s slop estimator were employed to examine thetrend and magnitude of the rainfall changes, respectively. The association between rainfall, temperature and crop yield was also evaluated by the Pearson correlation coefficient (r) results. The area-averaged minimum and maximum temperature of the region is 26.2mm and 62.9 mm, and it varies from 10.46 to 39.34 mm and 24.06 to76.7 mm respectively. The average annual temperature in the region is about 44.5 mm. The region is characterized by a diverse climate, which ranges from dry and hot lowlands to wet and cold highlands. The area-averaged annual minimum and maximum rainfall of the region is 629.33°C and 855.12°C, and it varies from 313.7°C to 660.7°C and 426.7°C to899.3 °C respectively
