Food Security, Agriculture and Climate Change

Food security is achieved when all people have access to an adequate supply of safe and nutritious food. Currently there are around one billion people who are inadequately fed and this number is likely to double in the next 30 years. In this module you will look at the food system and the range of issues that ultimately determine who eats what. It addresses issues contributing to variation in food availability, the access that people have to food and the different ways in which food is utilised, and you will examine ways in which crops accumulate biomass and undergo reproductive development. You will consider why crop plants are so sensitive to biotic and abiotic stress and why there is so much concern about the effects of climate change on food availability and food prices. The impact of the food production system on the environment is considered along with the tensions arising from our quest for both food security and energy security. Factors impacting food safety and quality are discussed. The approach to the study of these issues is interdisciplinary in nature. The course takes an international perspective on GFS (Global Food Security)
