This is a collection of three papers on systems agriculture, written in the early -mid 1980s. The first outlines some key concepts, methodologies and practices used within the systems approach to agriculture. It emphasises experiential learning, contrasting its application within the conventional, reductionist methodology and the systems methodology. Discussing varieties of systems approaches to problem solving, the author discusses in detail the distinctive approach used by Hawkesbury Agricultural College. The second paper discusses Hawkesbury's curricula initiatives, contrasting it with other learning and research paradigms used in Australia. These emphasise experiential learning to address complex problem solving. The final paper reflects on action research concerning the development of the School of Agriculture at Hawkesbury. Viewing the school as a purposeful sub-system within a complex macro-system of agriculture, the design of appropriate activities and structures in the School are discussed.
