Abstract

The role of coffee (Coffee arabica L.) in supporting producers had been closely to ancient practices, currently and the hope of next generation. It is the only crop which more than 25 million people in the world depend on, and the second most important commodity next to oil. However, in recent decades, coffee production has been influenced by severity of climatic changes. Agronomic practices have great function in sustain coffee production due to their attribution in buffering climatic change. Thus, this review conducted with the intension of agronomic practices task in buffering of climatic change impacts in coffee production and productivity. Because of climate change, the optimum production zone for coffee is projected to decrease up to 40% and at the end of this century, temperature will rise by 4-6°C. This severity and hazardless will tremendous in developing countries which extremely vulnerable to the risk. Furthermore, deforestation due to over population and absence of awareness in agroforestry are another problem increases the risk of climate change. Familiarity of contributions of agronomic practices in mitigating climate change is less recognizing and practiced informally than improve and scientific way. However, shading has capacity to reduce air temperature by 4°C, banana intercropping with coffee contributed as sources of income in off season for coffee yield. Finally, agronomic practices such as shading, mulching, irrigation, intercropping, pruning and soil conservation practices are the best option for sustaining coffee production and for buffering the direct and indirect impacts of climatic changes.

Summary

Introduction

More than 141 species of coffee are found and originated in different belt of tropical African countries. Coffee arabica is originated in south western parts of Ethiopia and the most cultivating among the three coffee species due to its quality, rich aroma, and low caffeine content (Santos et al, 2016). Coffee canephora is the contributing coffee production which is used as sources of disease resistance and high yielder but less priority on the market due to high in caffeine content and woody bitter (Reyes, 2010). Coffee is one of the most important global crops and provides a livelihood of more than 25 million of people whose living in developing countries (DaMatta et al, 2018). Despite its principal contribution in economic development, coffee arabica is more vulnerable to climate change due to adapt a very narrow of daily temperature (18-23oC), hate cold and frost temperature and highly sensitive to rainfall variability and drought
