Implications of quality based agri food supply chains on agri social systems

The present research aimed at deriving the conditions under which high-valued coffee can significantly increase household incomes and therefore enhance living conditions of people in rural areas by using the example of small-scale coffee producers from south Colombia; the study was based on the analysis of specialty coffee farm systems. In the center of consideration was the family farm system; the theoretical basis consists of the decision making behaviour of small-scale coffee farmers. Moreover, the theoretical framework was described by the rational choice theory. The outcome of the conceptual framework was the differentiation of objective environment in social environment, physical environment, and the belif system of farm managers.
