Production of Global Livestock system

Wenguo Wang

The global livestock sector is rapidly changing in response to globalization and growing demand for animal-source foods, driven by increase and increasing wealth in much of the developing world. The rapid rate of urbanization seen in many countries is not only linked to growing affluence but also gives rise to changes in people’s food preferences; usually tending towards greater convenience and higher standards of safety. As well because the many benefits and opportunities related to rapid sector transformation and growth, they're also related to social, environmental and public health risks. Moreover, there is a growing appreciation that the livestock sector needs to operate in a carbon-constrained economy, resulting in increasing competition for land and water resources, and growing pressure for the sector to be managed cleanly, safely and sustainably.
