Using stochastic frontier and cost-benefit analysis, a sample of 316 smallholder farmers in Dak Lak was chosen to analyze the economic impacts of sustainable and conventional coffee farming on farmers’ welfare. In addition, we conducted field observation and key informant interviews to describe several farming practices. The results highlight the fact that farmers’ decisions to participate in sustainable coffee farming are mainly driven by economic benefits. Sustainable farming is more cost-effective and profitable than conventional farming, despite the insignificant difference in production efficiency. Improvement of education, farming knowledge, and collective actions could mitigate negative effects of small-scale production for sustainable coffee farmers. Pesticide management, shade coffee encouragement, and reduction of excessive fertilization, over-irrigation, and unproductive coffee varieties are recommended for sustainable development of the sector.

Introduction Despite the fact that Vietnam remains the world’s most competitive coffee producers, thousands of rural coffee farmers are now struggling with price volatility and are losing hope of improving their main source of income.
