Achieving food security in a ‘perfect storm’scenario is a grand challenge for society. Unless 50% more food, 50% more energy and 30% more freshwater are available by 2030, a ‘perfect storm’is envisaged where there would be simultaneous shortages of all of these on a global scale [1]. This becomes an even more ‘wicked problem’when climate change and an expanding global population act in concert, making the challenge of achieving global food security even more complex and demanding.Food security ‘exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life’[2, Plan of Action no. 1]. It is determined by four factors:(i) availability (from agricultural production and land-use or exchange);(ii) stability of supplies (eg seasonally and from year to year);(iii) access (dependent on financial means but also physical access and social factors); and (iv) biological utilization of food (eg nutritional diversity and food safety issues)[3]. It is estimated that almost one billion people face hunger through lack of macronutrients [4], and a further one billion lack sufficient micronutrients, leading to both negative health and development outcomes [5].
