Abstract

The concerns about potential energy shortages and food shortages are addressed relative to needs of an increasing world population. Interacting relationships between available energy supplies and food supplies are reviewed from different aspects, including the increasing competition for water and land as such relate to energy, crop and livestock production. This overview should aid researchers, producers and consumers to better understand the complexities in making choices to meet the challenge of assuring ample amounts of energy to produce food in optimum quantities.
