Book Description
Excerpt from Population and Land in World Agriculture: Recent Trends and Relationships In the fourth and final part, a general theory of the growth of the agricultural labor force is presented. Three hypotheses to explain the growth of the agricultural population are developed on the basis of the material presented in the earlier sections and other evidence, and then tested by means of regression analysis. A substantive discussion of the regres sion results leads us to a generally satisfactory explanation of the growth of the agricultural labor force.

Book Description
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.

Book Description
Extract: Technological change will be essential in increasing crop production to meet the future world food needs because the world's population is increasing at a much faster rate than is the increase in usable agricultural land. Although only about half of the world's estimated 3 billion hectares of arable land is currently used for crop production, the remainder is generally believed to be only marginally productive. Cropland area has actually decreased in some regions of the world. This study measures agricultural land availability and trends and provides specific land constraints to world food production projections.

Book Description
This timely collection of 15 original essays written by expert scientists the world over addresses the relationships between human population growth, the need to increase food supplies to feed the world population, and the chances for avoiding the extinction of a major proportion of the world's plant and animal species that collectively makes our survival on Earth possible. These relationships are highly intertwined, and changes in each of them steadily decrease humankind’s chances to achieve environmental stability on our fragile planet. The world population is projected to be nine to ten billion by 2050, signaling the need to increase world food production by more than 70 percent on the same amount of land currently under production—and this without further damaging our fragile environment. The essays in this collection, written by experts for laypersons, present the problems we face with clarity and assess our prospects for solving them, calling for action but holding out viable solutions.
