Livestock are important sources of methane. The United States Environmental Protection Agency calculated that livestock, especially ruminants such as cattle and sheep, account for approximately one-third of global anthropogenic emissions of methane (US-EPA, 2006). The methane is produced primarily through the process of enteric fermentation and released through the process of eructation (Crutzen, 1995). In addition, N2O emissions are generated by livestock through secretion of nitrogen through the urine and faeces.The technical mitigation potential per region for all management practices (i.e. restoration of degraded lands; cropland management; grazing land management/pasture management; management of agricultural lands) and all affected GHGs is shown in Figure 1. Clearly, mitigation through the different management practices can substantially contribute to global climate change mitigation efforts.
