How to Feed the World

February 1, 2025
Food for thought. To begin a book about food with the word "Catastrophism" and a quotation from Thomas Robert Malthus' 1798Essay on the Principle of Population--as this book does--is to invite pessimism. Malthus famously wrote that "the power of population is infinitely greater than the power in the earth to produce subsistence for man." Now in the wake of global climate change and soaring world population, Malthus' words seem more prescient than ever. "Inevitably," Smil writes, "rising temperatures and increasing CO2 concentrations will have substantial plant-specific and regional differences," possibly cutting corn and rice yields in Asia and Latin America. The author of dozens of books and a professor emeritus at the University of Manitoba, Smil aims to be fair. Indeed, he insists that he's "agnostic about long-term prospects of the global food supply." But when push comes to shove, he chooses optimism and insists that "it is rational to argue that, barring mass-scale conflict and unprecedented social breakdown, the world will be able to feed its growing population beyond the middle of the 21st century." Malthus would disagree. So would recent authors who have written books that sound alarms about food insecurity and famine. Pessimists point to deforestation, the erosion of democratic institutions, and war. Smil, though, offers a quantitative approach. "Many books about agriculture and food do not contain many numbers, but this book is teeming with them," he writes. "Numbers are the antidote to wishful thinking and are the only way to get a solid grasp of the modalities and limits of modern crop cultivation, food, and nutrition. With this foundation it is far less likely you will make incorrect interpretations or misunderstand the basic realities of food." A sensible vision of the future that calls for "incremental changes."

Researcher and policy analyst Smil (Invention and Innovation, 2023) takes readers on a scholarly and accessible exploration of the history, key concepts, and important questions about what we eat. Smil unpacks challenges for eaters (famine, malnutrition, waste). He pointedly asks why we are not upset that one-third of food produced is wasted and asks the related question of why the planet's food supply is so uneven. He notes that the history of cultivation provided more available calories for eaters but also resulted in today's problem of a mere 20 species accounting for 75 percent of crops. Smil's book has answers and prescribed actions to "change the way the world feeds itself" in the form of incremental changes (less waste, more organic farming, cultured meat) and in the pursuit of agricultural practices beyond reliance on current staple crops. Smil is serious in his assessments and calls to action but cautions readers against food catastrophism that lurks in the collective consciousness. A necessary book for readers seeking authoritative information on the future of successfully nourishing the world's growing population.
