The researchers underlined that the question of how climate change would alter the already "fragile relationship" between human beings and livestock was "fraught with uncertainty". About 70 percent of the world's 1.4 billion "extreme poor" - people earning less than US$1.25 per day - are known to depend on livestock for their livelihood. The livestock population is exploding as demand for meat and milk products grows in developing countries - by 2007 developing countries had overtaken developed countries in meat and egg production, and were closing the gap in milk production, the report said.
To meet rising demand, global annual meat production is expected to expand from 228 million tons to 463 million tons by 2050, with the cattle population estimated to grow from 1.5 billion to 2.6 billion, and that of goats and sheep from 1.7 billion to 2.7 billion, according to FAO estimates. "During the early stages of intensification of livestock production, large-scale livestock production units tend to be established near to growing urban centres, which places large livestock populations in close proximity to large human populations."
The report noted that city residents in poor countries often kept livestock in cramped and unsanitary conditions close to their homes. "This can foster the emergence and spread of diseases affecting both animals and humans." Highly infectious diseases that originated in animals, such as severe acute respiratory syndrome (SARS) and the influenza caused by the A (H1N1) virus have recently hit the headlines…..
