World’s Challenge : Feeding 9 Billion People (Reprint) (Paperback) (Marion Guillou)
about this item
If a global population of 9 billion by 2050 is to be fed adequately, more food must be produced and this in keeping with increasingly stringent standards of quality and with respect for the environment. Not to mention the land that must be set aside for the production of energy resources, industrial goods, carbon storage and the protection of biodiversity.
