Family farming system is the most important agrarian system in Kermanshah province. The review shows that few studies have focused on vulnerability in Kermanshah's family farming system; while assessments of vulnerability can provide an important guide to programmers and decision makers on resource allocation at various levels, and it can improve public awareness of risks. So, the main purpose of this paper is to assess economic, social, and environmental vulnerability by Fledbrugge & Von Braun formula. Wheat farmers in Kermanshah province were the target population for this study. Using a three-stage sampling, 247 wheat farmers were selected. A five point Likert scaling showed that coping of farmers are less than their hazard perception in the farming, Also more investigation revealed that family farming system have more vulnerability in the environmental (mean of 3.25), economic (mean of 3.20) & social (mean of 3.11) aspects.
