This report presents a global overview of the role of livestock in nutrition and food security, and discusses ways of meeting the expected increase in demand for livestock as a source of food with limited resources. It examines how livestock contributes to food security in three population groups — livestock-dependent societies, small-scale mixed farmers and urban dwellers — and the main challenges they face in producing enough food.

The first section of the report discusses how livestock contributes to food security, including economic factors that affect the choice of foods, and the stability of livestock food supplies. The second section examines the contribution of livestock as a source of food in each population group, and the last part of the report looks to future prospects for producing enough food in the context of risks such as water shortages. It concludes that careful management of livestock food systems will be key in building a stable livestock food supply to meet future needs.
