The direct and indirect effect of climatic variability is one factor responsible for the oscillations and frustrations of the Coffee improvement in Ethiopia. The relationships between the climatic parameters and the agricultural production are quite complex, because environmental factors affect the growth and the development of the plants under different forms during the growth stages of the coffee crop. Over the last decades, the temperature in Ethiopia increased at about 0.2°C per decade, while the spatial and temporal variability of precipitation is high. Such rising temperature and erratic rain fall are threatening sustainable coffee production in Ethiopian by enabling outbreak of infection diseases (coffee leaf rust) and infestations of insect pests(coffee berry borer) that decrease the quality and yield of coffee. Hence different mitigation options are an absolute necessity, such as awareness of farmers about resultant treats of climate change, information on change in the biology of the pathogen and insect pests, shade tree planting and collaborative scientific research during development of stress resistance/tolerance variety with support of new molecular tools may help to reduce the vulnerability of Ethiopian coffee economy to continued changes in climate.
