The debate on health, nutrition and food security could not have arisen at a more opportune time. The recent pandemic has given rise to increased food and nutrition insecurity for individuals, families, and communities. The crisis threatened the food security and nutrition of millions of people, many of whom were already suffering. We face possible disruptions to the functioning of food systems, with severe consequences for health and nutrition. Pandemics create a greater burden for poorer countries and countries since they are already pressure of inadequate food supplies. With concerted action, we can not only avoid some of the worst impacts but do so in a way that supports a transition to more sustainable food systems that are in better balance with nature and that support healthy diets – and thus better health prospects for all. This book aims to highlight the impact of pandemics in food systems and nutrition security. It draws on the experience from the past and present pandemics to better prepare the world for future crises.
