Increasing food prices have renewed concerns about long-term agricultural demand and supply in the global economy. This book looks at results, methods, and data on international agricultural productivity for a better understanding of long-run trends and the policies that determine them. By presenting an international assessment of total factor productivity growth in agriculture, including up-to-date empirical analysis for developed and developing countries and regions, it provides a response to the rising global scarcity of agricultural production. It is essential reading for researchers, poli.

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.

Recent volatility in agricultural commodity prices and projections of world population growth raise concerns about the ability of global agricultural production to meet future demand. This report explores the potential for future agricultural production to 2050, using a model-based analysis that incorporates the key drivers of agricultural production, along with the responses of producers and consumers to changes to those drivers. Model results show that for a percentage change in population, global production and consumption of major field crops respond at nearly the same rate. In response to a change in per capita income, the per-centage change in crop consumption is much lower, about one-third the percentage change in income. The model also suggests that the global economy absorbs changes in agricultural productivity growth through compensating responses in yield, cropland area, crop prices, and international trade.
