Climate change has affected coffee planting, and the coffee crisis is brewing. Changes in temperature and precipitation will reduce the yield and quality of coffee and increase the pressure of diseases and pests. Research shows that an average increase of 2  degree in temperature will increase the risk of diseases (coffee leaf rust) and pests (coffee longicorn beetle). In fact, most possible solutions are either expensive or have negative consequences. 
The economic effect of coffee is significant. It can increase capital investment to build shading system or widely control diseases and pests.
 More economical and feasible solutions need to be studied.
