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.

“An urgent and at times terrifying dispatch from a distinguished reporter who has given heart and soul to his subject.”—Hampton Sides In The End of Plenty, award-winning environmental journalist Joel K. Bourne Jr. puts our fight against devastating world hunger in dramatic perspective. He travels the globe to introduce a new generation of farmers and scientists on the front lines of the next green revolution. He visits corporate farmers trying to restore Ukraine as Europe's breadbasket, a Canadian aquaculturist, the agronomist behind the world's largest organic sugarcane plantation, and many other extraordinary farmers, large and small, who are racing to stave off catastrophe as climate change disrupts food production worldwide. A Financial Times Best Book of the Year and a Finalist for the PEN / E. O. Wilson Literary Science Writing Award.

Since the 1960s, breakthroughs in agriculture have made it possible to satisfy the world's increasing requirements for food. Can this trend continue over the next thirty years when the world population is projected to exceed eight billion? This book takes a critical look at the immediate challenges for feeding the population just a generation from now. Based on the 10th International Symposium sponsored by the Nutrition Committee and the Trustees of the Rank Prize Funds, the volume examines the full range of related issues, from food economics to resource allocation and crop yields. Beginning with an analysis of future food needs, the articles cover basic resources and constraints, applications of science to increase yield, the role of animal products in feeding eight billion people, and diverse social issues. The book provides insights into some of the most important questions we will be faced with in the coming years, making it an invaluable resource for a wide range of researchers in agriculture, the environment, and public policy.

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.

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

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.
