A study of coffee growers in Guatemala illustrates the effect of fair trade practices on growers. In this study, thirty-four farmers were interviewed. Of those thirty-four growers, twenty-two had an understanding of fair trade based on internationally recognized definitions, for example, describing fair trade in market and economical terms or knowing what the social premium is and how their cooperative has used it. Three growers explained a deep understanding of fair trade, showing a knowledge of both fair market principles and how fair trade affects them socially. Nine growers had erroneous or no knowledge of Fair Trade. The three growers who had a deeper knowledge of the social implications of fair trade all have responsibilities within their cooperatives. One is a manager, one is in charge of the wet mill, and one is his group's treasurer. These farmers did not have a pattern in terms of years of education, age, or years of membership in the cooperative; their answers to the questions, "Why did you join?" differentiate them from other members and explain why they have such an extensive knowledge of fair trade. These farmers cited switching to organic farming, wanting to raise money for social projects, and more training offered as reasons for joining the cooperative, other than receiving a better price for their coffee.
