Document Summary
Enteric fermentation in livestock: emissions associated with microbial fermentation during digestion of feed by ruminant (mostly cattle and sheep) and some non-ruminant domestic livestock. Manure management: emissions associated with the decomposition of animal wastes while held in manure management systems. Rice cultivation: methane emissions from anaerobic decay of plant and other organic when rice fields are flooded. Agricultural soils: emissions associated with the application of fertilisers, crop residues and animal wastes to agricultural lands and the use of biological nitrogen-fixing crops and pastures. Prescribed burning of savannas: emissions associated with the burning of tropical savanna and temperate grasslands for pasture management, fuel reduction, and prevention of wildfires. Field burning of agricultural residues: emissions associated with the burning of cereal, sugar cane and crop stubble. Requirement to increase production in less predictable climate. Global production of meat is thought to double from 229 million tonnes in 1999/2001 to.
