Nowadays attention to the environment is important in all parts of the country especially in rural areas. Therefore, environmental protection is considered as a public social responsibility that everyone, including the villagers contribute to. Villagers connect to environment and natural resources through their lifestyle and activity. Present study was conducted in spring 1395 with the aim of analyzing the social responsibility of villagers regarding environmental sustainability. For this purpose, descriptive-analytical methodology was used using library resources and field study (survey and questionnaire tool). The statistical population of the study consisted of 213 rural households in four districts of Khaf city. A randomized stratified sampling method was used to collect data using a researcher-made questionnaire, which was based on indicators and components of the five dimensions of social responsibility extracted from theoretical literature. Findings of this study indicate that rural households are poor in environmental, ethical and social dimensions, moderate in economic dimension, and good in legal aspects. Also, using Cooper's prioritization model, villages were ranked based on their level of social responsibility. The village of Mazraeh Sheikh obtained the highest score and the village of Barbad was ranked second. In other words, villagers living in these villages have more responsibility toward environment. Thus it can be said that in existing conditions, preservation of the environment has not formed as a social and moral concern and collective behavior among villagers. Such a situation could be due to the weakness in strict and principled implementation of environmental laws and lack of environmental awareness in rural environments.
