|Description=Food production will have to increase in order to feed the world’s growing population. However, with increasing prosperity and falling production costs, dietary patterns are shifting to include a higher proportion of meat and milk. In the last few decades, traditional mixed farming systems have not been unable to raise production levels sufficiently to meet increasing demand. Consequently, modern livestock production systems are expanding rapidly particularly for poultry and pork, creating growing demand for crops. This trend started in high-income countries and is now observed in emerging and developing countries ([[Bruinsma, 2003]]). | |Description=Food production will have to increase in order to feed the world’s growing population.

Key policy issues
- What are the impacts of increasing livestock production on land use, greenhouse gases and other emissions to air and surface water?
- How does the use of marginal lands for grazing increase the risk of degradation and loss of productivity, inducing more forest clearing?
