Agriculture is critical for human welfare, providing food, employment, income, and assets. In the past, agricultural research and development largely focused on improving production, productivity, and profitability of agricultural enterprises. Nutrition and other benefits of agriculture were not always optimized, while the negative impacts on health, well-being, and the environment were often ignored. This was especially problematic for livestock systems, with especially complex negative and positive impacts on human health and well-being.
