The Second Report of the State of the World’s Animal Genetic Resources (AnGR) and analysis of Sub-regional reports on AnGR in Asia and the progress report of Global Plan of Action for AnGR in Southwest Pacific suggested that vigorous efforts still need to be made to strengthen the main elements of sustainable management of AnGR. It has been amply highlighted that to check erosion and loss of AnGR, to achieve food security, improve human nutritional status, and enhance rural development, the efforts to conserve, develop, improve and sustainable use of AnGR needs to be enhanced at national, regional and global level. APAARI under its APCoAB program thus organized a Regional Workshop on Underutilized AnGR and their Amelioration from March 4-6, 2019 at MARDI, Malaysia. The Workshop provided a platform for sharing experiences/knowledge relating to underutilized AnGR of Asia-Pacific that have food and nutritional value, gave a sub-regional assessment of the importance of most potential AnGR and also provided a status of their R&D for exploring the possibilities of their commercial use and eventual benefit to smallholder farmers.
