Abstract

Climate change and livestock production are deeply interconnected. Livestock contributes significantly to climate change while simultaneously being heavily impacted by it, creating a critical sustainability challenge for our planet. Globally, livestock are responsible for about 14.5% of anthropogenic greenhouse gas (GHG) emissions, primarily methane and nitrous oxide, which are potent warming agents. Methane, produced during the digestive process (enteric fermentation) of ruminants like cattle, sheep, and goats, accounts for a significant portion of livestock emissions. Nitrous oxide emissions mainly arise from manure management and fertilization processes in feed production. Additionally, land-use changes, driven by increasing demands for grazing and feed crops, further exacerbate carbon emissions.
