As the consumption of animal protein and products rises along with global standards of living, CRD will require transformations in livestock-centred livelihoods. Livestock are a key contributor to global food security, especially in marginal lands where animal products are a unique source of energy, protein and micronutrients . However, they also contribute disproportionately to total annual anthropogenic GHG emissions globally and influence climate through land use change, processing and transport through emitting CO2, animal production by increasing methane emissions, and feed and manure production by emitting CO2, nitrous oxide, and methane, . Mitigation of livestock emissions can be achieved by implementation of various technologies and practices such as improving diets to reduce enteric fermentation, improving manure management and improving animal nutrition and genetics ; altering land use for grazing and feed production, altering feeding practices, improving manure treatment and reducing herd size . Adaptation strategies in the livestock sector include changes in animal feeding, genetic manipulation, alterations in species and/or breeds , shifting to mixed crop-livestock systems , production and management system modifications, breeding strategies, institutional and policy changes, science and technology advances, and changing farmers' perceptions and adaptive capacity .
