Resumen
Descripción
By 2050 the world will need to feed an additional 2 billion people and will require 70 per cent more meat and milk. The increasing future demand for livestock products, driven by increases in income, population and urbanization will impose a huge demand on feed resources. Sustainability of feed production systems is being challenged due to biophysical factors such as land, soil and water scarcity, food-fuel-feed competition, on-going global warming and frequent and drastic climatic vagaries, alo ng with increased competition for arable land and non-renewable resources such as fossil carbon-sources, water and phosphorus. A key to sustainable livestock development is efficient use of available feed resources including reduction in wastage, and enlargement of the feed resource base through a quest for novel feed resources, particularly those not competing with human food.
