Greenhouse gas emissions in Malaysia quantifying methane emissions from livestock

Abstract

The rearing of animals for domestic consumption and export invariably lead to the production of methane as a product if digestion. This study investigated the emission of methane from Malaysian livestock between 1980 and 2008. Seven categories of animals identified were camel, buffalo, sheep, goats, horse, pigs and poultry. The estimation of methane was based on the IPCC Tier 1 and Tier 2 methods. Methane emission from cattle rose by 44% within the period from 45.61Gg to 65.57Gg. Buffalo recorded a drop in methane emission by 54% from 17.12Gg to 7.86Gg while the methane emission from sheep initially rose by 350% in 1992 only to drop by another 56% by 2008. Goats emission only declined by 17% from 1.79Gg to 1.49G. Methane emission from horse has been consistent at around 0.14Gg. The decreasing stock of pigs has led to a drop in methane emission from these set of animals with most of the emission coming from manure management. Poultry production has seen a rise in methane emission by 274% from 2.18Gg to 8.17Gg. The overall increase in methane emission from all the livestock is 20% from 81.83Gg to 98.76Gg. With the aggressive drive of government to boost cattle and goat production, there is the likelihood of an increase in methane emission in the future and mitigation options will have to be applied.
