Climate change has arisen due to "enhanced greenhouse effect", as a result of human activities and lifestyle. Mitigation of greenhouse gases is dependent on climate change risk perception. Therefore, the present study aimed to provide a conceptual model to determine risk perception and explore whether knowledge about causes and consequences of climate change influence individuals’ environmental attitudes, beliefs in the happening of climate change, and risk perception. The study was designed as a cross-sectional survey. The study sample consisted of 320 undergraduate students who were selected through random sampling. Structural Equation modeling showed that the relationship between knowledge of causes and consequences and risk perception was mediated by environmental attitude and beliefs. Respondents with higher knowledge about the causes and consequences of climate change are significantly more likely to consider climate change as a risk. Knowledge of causes and consequences has a direct effect on the belief that climate change is happening and on environmental attitude, and indirect effect on risk perception. Environmental attitude and belief have a significantly positive effect on risk perception. The suggested model could account for about half of the variance (49%) in risk perception. The results showed that the suggested framework is an effective tool for the prediction of risk perception.

Integrated Pest Management (IPM) is well known as a pro-environmental technology in agriculture. Therefore, investigating adoption of IPM mechanisms is crucial for agricultural products such as pistachio in Iran. The main purpose of this study was to assess the role of factors affecting IPM adoption by pistachio growers in Kerman Province. Survey was the research method and it was executed using researchers-designed questionnaire. Totally, 225 pistachio growers were selected as sample size, using two-stages random cluster sampling method. Validity of the questionnaire items was entirely approved by a panel of experts. Cronbach’s alpha coefficient was used for reliability approval. Findings revealed that individual factors including age, education, farming experience, motivations, participation and innovative spirit in conjunction with economic factors such as income, and technological costs affect IPM adoption procedure. In addition, educational services along with IPM technical knowledge and environmental attitude positively changed IPM adoption. The result of structural equation modeling illustrated that education, innovative spirit, life motivation, welfare motivation, income, technological costs, educational services and IPM technical challenges can significantly predicte IPM technical knowledge by direct effects. Indeed, IPM technical knowledge promotes environmental attitude and directly improves IPM adoption. Some practical recommendations are presented based on the research findings.
