This paper examines the hypothesis that social capital at the individual level affects environmentally friendly practices. Social capital represents the social connectedness of the individual. An individual with higher social capital is more likely to have better exposure and access to information about the importance of environmentally friendly practices. We study sustainable agricultural practices among Georgia farmers and examine whether their social capital levels have any effect on, (1) their adoption of sustainable agricultural practices, and (2) the extent to which they engage in these practices. Using the Georgia Social Capital Survey our measure of social capital is associational activities. We address a number of econometric issues: potential endogeneity of the social capital variable, peer-group effect in the form of social pressure, and a sorting issue.
