Food security in a changing world

Food security is defined as when all people at all times have access to enough food and a balanced diet. This depends on the production of food (agricultural yield), the availability of food (distribution, cost) and its nutritional value. Underpinning all food security are plants, whether eaten directly or consumed by stock animals.

This interdisciplinary unit will examine the factors that govern crop yields, e.g. how plants detect and respond to changing environments. The unit will also address the nutritional value of foods by exploring what is a balanced diet, how we get it and its effects on animal physiology and health.

The United Nations’ 17 Sustainable Development Goals (SDGs) are a challenge to the global community to improve human well-being, while also conserving Earth’s natural resources and the vital ecological functions on which we all depend. Goal Two, zero hunger, is relevant to the unit alongside many other interconnected goals. Meeting food production goals in the face of climate change, requires new approaches to agriculture and land management. The strengths and weaknesses of different agricultural systems (e.g. organic, subsistence, greenhouses or broadacre farming) and the role of GMOs, digital agriculture and robotics will be discussed. The unit will assist you to prepare for employment in food- and agriculture-related industries, with an awareness of sustainability principles and regenerative agriculture.
