IN THIS ISSUE: Hope for the World's Hungry /2 (Although the world population is certain to increase for the next twenty to twenty-five years, starvation is not inevitable, maintains Kenneth L. Robinson, professor of agricultural economics at Cornell. If population control is combined with agricultural expansion and improvement and if sufficient low-cost energy for fertilizer production is available, food production could increase at rates comparable to population growth.) ... Food and Energy: Their Interdependence /8 (Changes in agricultural methods could enormously reduce the current agricultural dependence on fossil fuels, points out Donald R. Price, associate professor of agricultural engineering.) ... Natural Gas from Agricultural Wastes /14 (Anaerobic fermentation of agricultural wastes such as cow manure can provide a renewable source of clean energy as well as a solution to a waste-disposal problem. The technology and its implications are discussed by William J. Jewell, associate professor of agricultural engineering.) ... Chicken Manure to Chicken Feed: A Recycling of Agricultural Chicken Manure Nutrients /25 (The development at Cornell of a waste-to-protein conversion scheme by a controlled microbial process is explained by Michael L. Shuler, assistant professor of chemical engineering.) ... Fermentation Alcohol: A New Look at an Old Process /32 (The prospects for production of ethanol from agricultural materials rather than from petroleum, and for the use of ethanol as liquid fuel, are discussed by Robert K. Finn, professor of chemical engineering, who is directing research on improved fermentation processes.) ... Faculty Publications /39
