This study examines the determinants of farmers’ behavioral change with regard to agricultural practices in Svay Rieng province, Cambodia, to understand why some farmers grow vegetables and why others do not. It tests the assumption that behavior change (the switch/diversification from just rice production to vegetable cultivation) is multi-dimensional, and is an outcome of several factors such as physical and social distance, assessments of risk, quality of relationships and status. This includes a lack of confidence among farmers, and other household members, in their capacity to do so. That is, they lack a knowledge base with which to compare their skills and have limited access to market information, water, labor and extension services.
