Livestock contribution to climate change – A review

Livestock production system is a contributor to the climate change. Responding to the challenge of climate change requires formulation of appropriate long term adaptation strategies and mitigation options for the livestock sector. Factors affecting variability in enteric CH4 production requires urgent attention and efforts to decrease the uncertainty in GHG emission inventories. It is very essential to identify viable GHG reduction strategies. Clarity is required concerning the benefits of livestock, the negative impacts they can have on greenhouse-gas emissions and the environment, and the effects of climate change on livestock system. Although the reduction in GHG emissions from livestock industries are seen as high priorities, strategies for reducing emissions should not reduce the economic viability of enterprises. | Int.J.Curr.Microbiol.App.Sci 2019 8 9 1099-1107 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 09 2019 Journal homepage http www.ijcmas.com Review Article https doi.org 10.20546 ijcmas.2019.809.127 Livestock Contribution to Climate Change - A Review Ramandeep Kaur1 Parteek Singh Dhaliwal2 and S.S.

Introduction Livestock contribute 14.5 percent of the total annual anthropogenic greenhouse gas GHG emissions globally Gerber et al. 2011 . Livestock influence climate through land use change feed production animal production manure and processing and transport. Feed production and manure emit carbon dioxide CO2 nitrous oxide N2O and methane CH4 which consequently affect climate .
