National food security depends above all other factors on a resilient global food system. Understanding this system is crucial to effective decision-making and the avoidance of crisis.
One of the great deficiencies of our education is that few of us are taught systems theory. Yet everything of material importance to us – the human brain, the human body, human society, ecosystems, the atmosphere, the oceans, the financial system, the food system – is a complex system[1]. The behaviour of these systems, because so few of us study them, repeatedly takes us by surprise.
