Addressing the question of how to feed the world population in the future, this text covers land & crop nutrients & sustainability, water usage, applications of science to increase yield, and social aspects such as the use of new technology.

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.

As the world's population approaches seven billion people, some fear that Earth's citizens face a catastrophic food crisis in the near future. Furthermore, experts place the globe's population in 2050 at more than nine billion, a potentially overwhelming figure for the world's resources. Some worry how everyone will be fed as land, water, and other natural resources become more scarce. Others are concerned that not everyone will be able to afford food, and starvation may take hold of the world's population. However, some scientists are more optimistic, believing that the hunger problem will be erased from the planet by 2050. Feeding a Hungry World explores the problem of world hunger, how experts propose to cure this problem, and what booming population growth means for the future of food.

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.

“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.

The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. They are used in the calculation of many of the key development indicators commonly used by the United Nations system, including for more than one third of the indicators used to monitor progress towards the achievement of the Sustainable Development Goals. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections, which have been prepared since 1951 by the Population Division of the Department of Economic and Social Affairs. The 2019 revision presents population estimates from 1950 until the present for 235 countries or areas, which have been developed through country-specific analyses of historical demographic trends. It builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as information from vital registration and recent nationally representative household sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. These Highlights summarise key population trends described by the estimates and projections presented in World Population Prospects 2019.
