The economy of Swaziland is depended on agriculture. In 2009, it wasreported that agriculture, forestry, and manufacturing contributed 42% ofSwaziland’s Gross Domestic Product GDP. Besides economic importance, animalagriculture is important for food production and life sustenance. It is alsoviewed as a symbol of wealth and high social status particularly for the ruralfolks. Despite the merits of agricultural activities, agricultural production,particularly animal production, has been incriminated for an acceleratedemission of greenhouse gases. These gases are responsible for global warmingand climate change. The aim of this study was to determine the contribution ofanimal agriculture to greenhouse gases production and to elicit adaptationstrategies to climate change and the role of modern technologies as mitigatingmeasures. The minor and major greenhouse gases produced by farm animals werecomputed using the IPCC spread sheet for calculation of greenhouse gasesemissions. The minor greenhouse gases produced by farm animals were NOx and CO2 and the major gasses included CH4 and N2O.The greenhouse gas that was emitted the most by farm animals was CH4,24 Gg or 600 CO2e per annum. Ruminants were the major producers ofmethane. The producers of the least greenhouse gases emissions were nonruminants. Livestock produced 0.87 Gg of N2O per annum, a globalwarming potential of 259 CO2e. Feeding ammoniated straw and silageinoculating with transgenic rumen bacteria, animal breeding and manure storagetechniques, use of biogas digester with methane gas recovery and emphasis onnon ruminant production were possible strategies that could be employed toreduce greenhouse gases production from the livestock sector. It wasrecommended that feed preservation technologies, selection strategies, waterharvesting, storage and recycling strategies and intensive livestock productionsystems could be used as adaptation strategies to climate change in livestockproduction.
