Presently, hill-tribe coffee farmers across Northern area earn low income from coffee selling, due to the inefficient coffee transforming processes, which directly leads them to face indigent quality of life. Our project’s goal is to provide Raks Thai Foundation with effective research data in coffee transformation processes, as options for the hill-tribe farmers to gain better profits from selling coffee. In collaboration with Raks Thai Foundation, the team designed to identify the current limitation factors of coffee transformation processes in the target villages, Yod Phai and Huay Kee Per villages, which are located in Mae Chaem district, Chiang Mai, based on observation and interview. The team aimed to promote them the importance of coffee transformation processes using financial calculations as significant evidence, and provided possible approaches to overcome such barriers in term of realistic information, together with recommendations for the continuous use of approaches in the future.
