About this course

Despite the advancement in economic development and food technology, there are people living without the basic supply of sufficient and clean foods require for their physiological well-being. The World Food Summit of 1996 defined food security as existing “when all people, at all times, have physical, social and economic access to sufficient food which meets their dietary needs and food preferences for an active and healthy life”. This course introduces the factors affecting the sustainability of the contemporary food systems. It will also explain the consequences associated with food insecurity. Areas including technological advancement, economic drive, political stability, as well as socio-cultural influences will be analysed critically as insights to tackle the challenge of future food crisis.
