Growing
predominance of
livestock and its
impacts
• 1/3 of all cropland used to
produce feed crops
• 1/4 of ice-free land area
occupied by pastures
• 60% of mammals are livestock
• 70% of birds are poultry
• 40% of agricultural water use
Massive impacts on land, water,
air and biodiversity

(Data Source: FAOSTAT)
• 95% of enteric
fermentation
emissions in Asia from
19 countries
• 75% from: India
(38%), China, (18%),
Pakistan (13%), and
