Abstract

Climate change is a topic of discussion worldwide including in Ethiopia. Ethiopia is one of the country’s most vulnerable to the impacts of climate variability and change on agriculture. This study investigates were to examine crop water requirements under climate changes scenarios for maize crop at Mirab-abaya woreda which is situated in 6.18◦ N latitude and 37.77◦E longitude. Dynamically downscaled climate model outputs were obtained from the CORDEX-Africa program for (RCP) Representative Concentration Pathway of both scenarios which were used for future climatic conditions of the future periods; (2021 – 2050). The projected data was quality checked, biased corrected and model performance was evaluated. Mann Kendall's trend detection and Sen.’s slope estimator were used by XLSTAT software to evaluate the trends of projection and to detect changes. Hargreaves method was used to estimate current and future crop evapotranspiration of Maize. The result for observed and future revealed that the maximum and minimum temperatures increase in all time horizons. However, Projections of future rainfall suggest that annual rainfall decreases in both scenarios, the current and future potential evapotranspiration show that increasing trend in both cases except the observed Mirab-abaya station.
