Closing the Feed Gap in Drylands for Enhanced Livestock Productivity and Efficient Resource Use
MetadataShow full item record
Livestock is the world’s fastest-growing highest-value agricultural sub-sector already accounting for about 40 % of agricultural GDP globally. By 2050 massive increases over 2005/7 amounts of cereals, dairy and meat will be needed: an extra of 2–3 Gt cereals, 0.66–1 Gt dairy products and 258–460 Mt meat. To meet this demand, large productivity increases are required as expansion of animal numbers and croplands is no longer an option. Hence, food and feed production will compete for land and water resources, particular in the drylands.
