Given the projected increase in the demand for animal-source foods in developing countries, trends in livestock GHG emissions and other environmental impacts, there is an urgent need to change livestock production. Despite its significant role in global GHG emissions, the livestock sector also has a large potential to reduce its environmental impacts while increasing productivity. Mitigation practices also have other co-benefits, addressing land degradation (conservation of natural resources), livestock waste, resource efficiency and income generation for the rural poor. Progress in implementation of mitigation actions has been slow. There is limited information on emerging experiences with Nationally Appropriate Mitigation Actions (NAMAs) development and implementation, pointing to the need to better document what is being done and to share knowledge and experience among interested countries. In particular, interested countries would benefit from better knowledge of the technical and stakeholder processes through which NAMAs are being developed; links between NAMAs and other livestock sector policies and programs; barriers to adoption of promoted practices and means to address them and financing arrangements for NAMA implementation. Supporting interested countries to share experiences in these and other dimensions would help reduce the gap between ‘intent’ and actual NAMA implementation.
