 Around the world, nearly one billion people rely on livestock for their livelihoods. They must be able to adapt to future changes in their environment and withstand the challenges that will arise, and so must their animals. How can we ensure livestock are more resilient in a changing world? A key solution is safeguarding animal genetic diversity. Genetic diversity provides the raw material for evolution as it allows livestock to adapt to challenges such as climate change, emerging diseases and pressure on feed and water resources. But this diversity is under threat. Out of 8,900 livestock breeds, 2,400 are at risk of extinction while 600 are already extinct. The Intergovernmental Technical Working Group on Animal Genetic Resources for Food and Agriculture advises countries and FAO in the Sustainable Management of Livestock Diversity. Identifying breeds at risk and implementing programs for their sustainable use and conservation are just some of the solutions. With more countries on board to manage livestock diversity, we can help ensure sustainable livelihoods and a food secure future for all.
