Decreasing food waste (FW) came to be an urgent need to achieve sustainable food ‎systems transformation. Measuring the youth's awareness towards FW represents an important ‎action to design an effective strategy intervention that aims reduction the percentage of FW. The ‎purpose of this paper is to explore the knowledge of youth regarding FW as well as identify ‎factors influencing this knowledge. To achieve the aim of this study, the primary data have been collected from 430 students at ‎Fayoum University, Egypt. The binary logistic regression (BLR) model was employed to ‎identify factors influencing FW knowledge among youth. Results showed that age, residence ‎place, and knowledge of social, economic and environmental impacts of food waste are significantly influencing knowledge about FW. The current results concluded and highlighted the ‎importance of designing an educational curriculum at universities including FW and sustainable ‎consumption concepts. So, youth's skills-building interventions through campaigns should be ‎regularly held to promote ‎changing norms and attitudes toward less FW and responsible ‎consumption behaviour to ‎accelerate the sustainable agri-food systems transformation in ‎developing countries.
