Five region-specific case studies in FAO's report suggest that GHG emissions can be significantly reduced by marginally improving production practices, while keeping production levels constant:
- In South Asian mixed dairy farming systems, emission can potentially be reduced by 38 percent by improving feed and feeding practices, as well as animal health and husbandry.
- For specialized beef production in South America, feasible improvements in forage quality, animal health and husbandry and grazing management could lead to an emission reduction of 19 to 30 percent.
- Similar mitigation interventions could reduce emission from West Africa's small ruminant sector by 27 to 41 percent.
- Improved manure management, adoption of energy efficient technologies, sourcing of low carbon energy and upgrading of feed, health and animal management in commercial systems can reduce emissions of pig production by 28 to 36 percent in East and Southeast Asia.
- In mixed dairy systems in OECD countries, reductions of emission by 14 to 17 percent are possible, through feed supplements, treatment of manure in anaerobic digesters and energy efficiency.
