In recent decades, degradation of natural resources (soil, water etc.) due to human actions causes environmental movements like environmental ethics. Environmental ethic theories emphasize a value-base of environmental behaviors. It seems that value-based factors such as moral norms and value orientations can affect human’ attitudes and behaviors. Farmers have direct relationship with environment resources such as soil, water etc. therefore, their attitudes and behvaiors in relation to these resources are very important. This study intended to investigate value factors including moral norms and value orientations among farmers in Shiraz County, Iran; and predicting their environmental attitude and behaviors by these value factors. The research population of this study was the farmers of Shiraz County, Iran.
