'Ain Ghazal, an archeological site located on the outskirts of Amman, Jordan, is one of the largest early villages known in the Near East. The site dates to the Neolithic period, during which mankind made one of its most significant advances, the adoption of domestic plants and animals as primary subsistence sources. Recent excavations at 'Ain Ghazal have(More)
In South Asia, and throughout the developing world, the predominant official approach to livestock development has been improvement of production by means of upgrading local breeds via cross-breeding with exotic animals. This strategy has led to the replacement and dilution of locally adapted breeds with non-native ones. This has resulted in an alarming(More)

SUMMARY Domestic animal diversity in developing countries is embedded in traditional farming and pastoral communities who manage their livestock according to their indigenous knowledge (IK) and in tune with local ecological constraints. Especially in marginal environments, local livestock breeds are crucial for sustaining rural livelihoods by producing a(More)
Background The FAO (FAO, 1999; FAO/UNEP, 1995) is alerting the global community to the alarming figures in respect to domestic animal diversity. It estimates that about one third of the world's recognized 5000 livestock and poultry breeds are endangered and that breeds become extinct at the rate of one per week. Nevertheless, the subject has received much(More)
SUMMARY This paper aims to suggest an alternative, or supplementary, conceptual and practical framework for livestock genetic resource conservation in developing countries. In a paradigmatic shift away from the reductionist approach of regarding 'breeds' as manifestations of certain genes that deserve to be either saved or not saved, an evolutionary model(More)
Pastoralists have a rich tradition of 'innovation', as continuous adaptation to new ecological and economic scenarios has been a prerequisite for their survival through the millennia. One of their greatest assets is the large number of locally adapted livestock breeds they have developed, which represent a major resource for climate change adaptation as(More)
Many local livestock breeds and minor species are in decline and may be lost because they cannot compete with high-yielding exotic breeds. Conserving these breeds is important: many have unique traits, such as hardiness and disease resistance, that are vital for future livestock production. One way to help ensure their survival may be to sell products from(More)
