Abstract
In Ethiopia, where vulnerability to climate change and variability is high, studying the impact of climate change at a local scale is critical for designing appropriate strategies for adaptive capacity. The study was conducted in Bishoftu area to examine the extent of climate change effects on the production of two chickpea varieties (Arerti and Habru) in the upcoming periods (2050’s and 2080’s) under two climate scenarios, RCP4.5 and RCP8.5. Future climate data were downscaled using an ensemble of two climate models (CSIRO-Mk3-6-0 and MIROC-ESM-CHEM0) with RCP4.5 and RCP8.5. Twelve years of crop data were collected from Debre Zeit Agricultural Research Center (DZARC). Soil data were also adopted from published documents of DZARC. Decision Support System for Agrotechnology Transfer (DSSAT) model was used for this study. The model employs all collected data to simulate days to flowering (DF), days to maturity (DM), and yield. Prior to simulations, the model was validated for its performance in simulating the yields of both chickpea varieties. The study revealed that the yield of Arerti will increase by 22% from the baseline yield of 2846 kg/ha by 2050’s under RCP 4.5. In contrast, by 2050’s under RCP 8.5, the yield of Arerti will reduce by 33%. Moreover, the study depicted that 2% yield increment of Habru from the baseline yield of 2787.5 kg/ha will be expected by 2080’s under RCP 8.5.The reason for yield increment and decrement could be due to the combined effects of mainly rainfall and maximum temperature versus the tolerance of respective chickpea variety. In general, RCP 8.5 has resulted in more reduction of yield of Arerti variety than RCP 4.5 scenario. However, Habru variety will benefit more from RCP 8.5 scenario. Therefore, chickpea production under a changing climate is possible with appropriate variety choice. The study appreciates similar studies to be conducted on other leguminous crops.
