Australian agriculture is a key part of the world's food supply system. The challenges of a rapidly growing population, climate change, and the limitations of land and fresh water all impact on the ability of agriculture to meet the demand for food, fiber and fuel. To address this demand an understanding of the complex factors that shape agricultural systems is necessary. Agricultural Science provides the research, technology and information for the sustainable, profitable and ethical development of the agricultural industry. Studies in agriculture include soil science, genetics, cropping and pasture systems, soil-plant interaction, livestock production, agricultural economics and agribusiness. Teaching methods consist of lectures from leading experts and industry representatives, weekly practical and laboratory classes and tutorials. This major also includes field work and two 3-day field trips. Teaching in agricultural science is also supported by the outstanding research and outreach activities of the Institute of Agriculture, the Centre for Legumes in Mediterranean Agriculture (CLIMA), the International Centre for Plant Breeding Education and Research (ICPBER) and the Australian Herbicide Resistance Initiative (AHRI).
