How Much Food Will Be Needed In 2050?

There have been many articles that compare the population of 2050 and the food requirements needed by that population. Examples include "Making Safe, Abundant Food Supply a Global Reality" and "Food Needs and Population" (additional resources). Dr. Terry Etherton highlights some of the approaches to population estimates and then seeks to translate into the quantity of food that would be needed to feed that 2050 population.
The question emerges, then, of whether there is more accurate approach for estimating projected food needs in 2050?

Two issues facing the world: food versus population

Population growth and increased per-capita consumption are driving global changes to how food is produced and distributed.

In particular, higher incomes have caused per-capita consumption of livestock products (and feed grains) to increase. However, these trends, like population growth, will not continue indefinitely.

Dr. Douglas Southgate, Jr. Professor of Agricultural, Environmental, and Developmental Economics, The Ohio State University, highlights several of the issues that will cause stress in the system of food production to support a slowing growing population. From the 2011 Annual Conference of the National Institute for Animal Agriculture, April 11 - 14, San Antonio, TX USA.
