A unique and accessible account of the interaction between population growth and agricultural innovation.

A realistic yet encouraging look at how society can change in ways that will allow us to feed an expanding global population. This book addresses the question of how we can best feed the ten billion or so people who will likely inhabit the Earth by the middle of the twenty-first century. He asks whether human ingenuity can produce enough food to support healthy and vigorous lives for all these people without irreparably damaging the integrity of the biosphere. What makes this book different from other books on the world food situation is its consideration of the complete food cycle, from agriculture to post-harvest losses and processing to eating and discarding. Taking a scientific approach, Smil espouses neither the catastrophic view that widespread starvation is imminent nor the cornucopian view that welcomes large population increases as the source of endless human inventiveness. He shows how we can make more effective use of current resources and suggests that if we increase farming efficiency, reduce waste, and transform our diets, future needs may not be as great as we anticipate. Smil's message is that the prospects may not be as bright as we would like, but the outlook is hardly disheartening. Although inaction, late action, or misplaced emphasis may bring future troubles, we have the tools to steer a more efficient course. There are no insurmountable biophysical reasons we cannot feed humanity in the decades to come while easing the burden that modern agriculture puts on the biosphere.

By 2050, we will have ten billion mouths to feed in a world profoundly altered by environmental change. How will we meet this challenge? In How to Feed the World, a diverse group of experts from Purdue University break down this crucial question by tackling big issues one-by-one. Covering population, water, land, climate change, technology, food systems, trade, food waste and loss, health, social buy-in, communication, and equal access to food, the book reveals a complex web of challenges. Contributors unite from different perspectives and disciplines, ranging from agronomy and hydrology to economics. The resulting collection is an accessible but wide-ranging look at the modern food system.

Global food prices have eased significantly from their record highs in the first part of 2008. As a worldwide economic downturn has gathered pace, commodity markets have weakened significantly. By October 2008, the UN Food and Agriculture Organization's Food Price Index stood at 164, the same level as in August 2007, and 25% lower than the Index's high of 219 in June 2008. However, this does not mean that policy-makers around the world can start to breathe a sigh of relief. For one thing, even at their somewhat diminished levels current prices remain acutely problematic for low-income import-dependent countries and for poor people all over the world. The World Bank estimates that higher food prices have increased the number of undernourished people by as much as 100 million from its pre-price-spike level of 850 million.

Deforestation. Desertification. Species extinction. Global warming. Growing threats to food and water. The driving issues of our times are the result of one huge problem: Us. As the population continues to grow, our problems will increase. And this means that every way we look at it, a planet of ten billion people is likely to be a nightmare. Stephen Emmott, a scientist whose lab is at the forefront of research into complex natural systems, sounds the alarm. TEN BILLION is a snapshot of our planet, and our species, approaching a crisis, and a stark analysis of where this leaves us. TEN BILLION is not another climate book. TEN BILLION is a book about us.

Nearly a third of the world’s population suffers from hunger or malnutrition. Feeding them – and the projected population of 10 billion people by 2050 – has become a high-profile challenge for states, philanthropists, and even the Fortune 500. This has unleashed a steady march of initiatives to double food production within a generation. But will doing so tax the resources of our planet beyond its capacity? In this sobering essay, scholar-practitioner Eric Holt-Giménez argues that the ecological impact of doubling food production would be socially and environmentally catastrophic and would not feed the poor. We have the technology, resources, and expertise to feed everyone. What is needed is a thorough transformation of the global food regime – one that increases equity while producing food and reversing agriculture’s environmental impacts.​
