The pathways and principles explored in this brief provide a summary of the current state of knowledge of ways to use agriculture to improve nutrition. Broadly accepted among development partners, these concepts are based on the best evidence available from the literature on food security, health, and nutrition and are supported by the experiences of field practitioners, including those implementing activities under Feed the Future. These concepts can aid in the design and implementation of nutrition-sensitive agriculture programs. This brief does not assume that all agricultural development activities are "nutrition sensitive."
