Abstract
The objective of this study was to estimate the greenhouse gas (GHG) emissions from practised cattle farming
systems (Stall, Semi-Intensive, Grazing, Tethering and Scavenging) and identify potential areas for GHG mitigation.
Using the Global Livestock Environmental Assessment Model (GLEAM-i), GHG emissions in 2016 were
2009 Gg CO2-eq/yr of which the Grazing system contributed 88.5%. Enteric fermentation produced about 75.8%
of the total GHG emissions. At an annual growth rate of 3%, the projected GHG for 2020 and 2025 would
increase by 12.6% and 30.7% respectively. The milk and meat emission intensities were far higher than the
global averages. A reduction in grazing by 10% and a 10% increase in use of anaerobic digesters to handle
manure resulted in a 4.4% reduction in annual GHG emission.
