The understanding of the genetic mechanisms of livestock adaptation to environmental challenges is becoming an important research topic in this time of rapid climate change. New tools and approaches are now available to investigate this complex phenomenon. Low-cost high-throughput technologies have opened the genomic era to agricultural species. All major farm animals have been completely sequenced and HapMap projects are completed or in progress. Low, medium and high-density SNP panels are available or under construction. Molecular information on many thousand markers has initiated the era of population genomics, which is the application of genomic approaches to population genetics. The comparison of patterns of diversity along the genome in animals originating in different environments and new GIScience-based models able to associate molecular markers to environmental variables promise to discover genomic regions associated to traits important for adaptation and to pave the way to the identification of causative genes. Local breeds adapted to a sustainable production in extreme and harsh environments will play a fundamental role in this process.
