The extensification onto upstream region can be regarded as a farmer’s behavioral adaptation to the climate change to look for the optimum temperature in growing coffee. This behavior is rampant for Robusta-dominant people agroforestry coffee (Coffea canephora) in Lampung Province, Indonesia. The negative impact certainly causes land degradation, while the positive impact on its quality has not been well-measured. This study aims to determine the effect on the upward shift on cropping area altitude to the coffee frruit quality using Ordinary Least Square (OLS) Regression Model. The field survey was conducted from June to August 2017. Samples of ripe cherry coffee collected from 32 sites in the approximate elevation of 300 to 1,170m ASL. The independent variables observed consists of sites elevation, slope steepness, and the exposition area of cultivation. Two indices of bean quality were used as the independent variables. First one was the index of [WD_1000]: the weight of 1000 dried coffee fruit. The other one was [FLOAT], the percentage of ripe coffee fruit floated in the water. Conclusion: For each a-100 m of upward elevation, the [WD_1000] was increased by 24.18g/1000 dried beans accompanied with the [FLOAT] by 1.99% of floating watered bean. It is recommended to conduct further research on revealing the effect on the coffee cup taste.
