  • As already mentioned, the livestock sector is large and growing rapidly.
    People in developing countries are consuming an increasing share of their diets in the form of meat, milk and eggs. While staple foods such as cereals and roots and tubers have declined as a share of the diet, per person consumption of milk has doubled, meat more than trebled, and eggs quintupled.
    Per capita consumption:
    Eggs: 5-fold increase
    Meat: 3-fold increase
    Milk: almost double
    This growth has been particularly striking since the 1980s, driven by rapid economic and social change.
    Rising incomes, urbanization and commercialization are transforming the demand for livestock products and hence the entire livestock sector.

    16. 16. US Dairy trends • Today, there are 9 million dairy cows in the US, 16 million fewer than existed in 1950. • Even though cow number have decreased dramatically (1950 versus 2013), milk production nationally has increased 60 percent. • The carbon footprint of a glass of milk is 2/3 smaller today than it was 70 years ago.
    17. 17. China Swine Example • China’s five year plan focuses on making farms larger and more efficient • Half of the world’s pigs live in China • 50 million sows w/ 20 piglets born alive • Equals annual production of 1 Billion pigs • Pre-weaning mortality causes 400 Million pigs to never make it to the market • One more pig per sow would mean 1 Million tons of feed saved
    18. 18. Sustainable Intensification is key! • Production intensity enhances biological efficiency • Production intensity and emission intensity are inversely related
    19. 19. Partnership on Livestock Environmental Assessment & Performance (LEAP) • Globally harmonized methodology for environmental footprints • LEAP = national governments, livestock industry, non-governmental and civil society organizations, leading researchers
