Livestock production provides food and raw materials in addition to being means of livelihoods to millions of people. However, their production is associated with pollution among which is greenhouse gas (GHG) emissions. Livestock contributes 80% of the total GHG emission from agricultural sector. These emissions are originated from enteric fermentations and manure management. Emissions from manure management are mostly Nitrous oxide. Five (5) sources of N O emission from livestock were identified and are dung 2 and urine from grazing animals deposited in pastures, indirect sources, animal wastes in stables and storages, application of animal wastes to land and burning of dung with emission proportion of 41, 27, 19, 10 and 3% respectively. IPCC developed methods for estimation N O emission designated as Tier 1, 2 and 3 respectively. Using Tier 1 method a total of 2 453.027 gigagrams of N O were emitted from livestock, considering class of livestock 2 ruminant dominated the emission with cattle alone emitted 47.83% of the total emission. Based on regions, Asia produces the highest emission from N O with 51% in the year 2016. 2 Tier 3 method can be used to get a relative accurate measurement of the emission as well as GLEAM model. Mitigation options should be explored in order to minimise GHG emission and environmental pollution from livestock as well as nutrients losses which translate to increase cost of production.
La production animale fournit de la nourriture et des matières premières en plus d'être un moyen de subsistance pour des millions de personnes. Cependant, leur production est associée à une pollution dont les émissions de gaz à effet de serre (GES). L'élevage contribue à 80% des émissions totales de GES du secteur agricole. Ces émissions proviennent des fermentations entériques et de la gestion du fumier. Les émissions provenant de la gestion du fumier sont principalement de l'oxyde nitreux. Cinq (5) sources d'émission de N2O provenant du bétail ont été identifiées et sont les excréments et l'urine d'animaux de pâturage déposés dans les pâturages, les sources indirectes, les déchets animaux dans les étables et les entrepôts, l'épandage de déchets animaux sur le sol et le brûlage des excréments avec une
