Why have we organized winter school? We believe everyone should be able to understand how important is Food Environment and Health Risk Assessment in Danube Region. The environment plays a crucial role in people’s physical, mental and social well-being. The degradation of the environment, through air pollution, noise, chemicals, poor quality water and loss of natural areas, combined with lifestyle changes, may be contributing to substantial increases of civilisation diseases. The production and consumption of sufficient, affordable and nutritious food, while conserving the natural resources and ecosystems on which food systems depend, is vital. Food systems play a central role in all societies and are fundamental to ensuring sustainable development. Sustainable food systems are critical to resolving issues of food security, poverty alleviation and adequate nutrition, and they play an important role in building resilience in communities responding to a rapidly changing global environment. 13 students from around the world joined our 2- week Winter School Programme in Slovak republic, Slovak University of Agriculture in Nitra, Faculty of Biotechnology and Food Sciences. CASEE Online Winter School was multidisciplinary, encompassing chemistry, environment, microbiology, nutrition, quality assurance, sensory analysis, management, food engineering and manufacturing and also about very actual problematic Covid-19 and its impact on agri-food sector.
