Characterization of Local Climate and Its Impact on Faba Bean (Vicia faba L.) Yield in Central Ethiopia

Climate change is a major threat to agricultural production and undermines the efforts achieve sustainable development goals in poor countries such as Ethiopia that have climate-sensitive economies. The objective of this study was assess characterization local climate its impact on productivity faba bean (Vicia L.) varieties (Gora Tumsa) Welmera watershed area, central Ethiopia. Historical (1988–2017) eight years crop yield data were obtained from National Meteorological Agency Holeta Agricultural Research Center. Trend, variability, correlation, regression analyses carried out characterize area establish association between change. received mean annual rainfall 970 mm with SD 145.6 coefficient variation (CV %) 15%. earliest latest onset April 1 (92 DOY) July 5 (187 DOY), whereas, end date rainy season September 2 (246 October 31 (305 respectively. average length growing period 119 days, CV% 35.2%. probability dry spell less than 7 days high (>80%) until last decade May (151 DOY); however, sharply declined reached 0% first (192 DOY). Kiremt (long occurs June September) belg (short falls February April/May) had increasing trends at rate 4.7 2.32 mm/year, maximum temperature showed trend 0.06°C per year by factor 0.34°C, which not statistically significant. 2014 exceptionally drought while 1988 wettest year. (JJAS) start rain day strong correlation negative Gora (r = −0.407 −0.369), findings suggests large constraints production. Investment sector enhance farmer’s adaptation capacity essential reduce adverse impacts variability yield. More research combines household panel long-term necessary better understand
