The livestock sector accounts for around one third of global agricultural gross domestic product (GDP) and is growing faster than most other agricultural sectors. Livestock’s expansion has mostly been driven by a combination of population growth, urbanization and rising incomes in many developing countries, which has raised demand for meat, milk and eggs. Consumption of livestock products is expected to further increase in the coming decades, offering opportunities for the development of the sector, poverty reduction and food security gains. However, the rapid pace of change could further marginalize smallscale producers. The risks to natural resources and human health must also be addressed to ensure sustainability. The Food and Agriculture Organization of the United Nations (FAO) promotes and facilitates the sustainable development of the livestock sector through actions such as: facilitating the access of small-scale livestock producers, particularly in developing countries, to increasingly competitive markets for livestock commodities; contributing to safeguarding animal and veterinary public health; maintaining animal genetic diversity; and reducing the sector’s environmental impact. Within this framework, FAO has, over the past two decades, integrated livestock-focused Farmer Field Schools (FFSs) in several of its projects and programmes and has contributed to building the capacity of many development stakeholders (INGOs, NGOs, research institutes, etc.) on the FFS approach for the benefit of small-scale livestock producers across developing regions
