Animal source foods can play an important role in improving nutrition, particularly in areas like the Sahel, where livestock is a key dietary resource and source of livelihood. This paper asserts that limited animal source food interventions are incorporated into development programming, using USAID Feed the Future initiatives as an example. The study used interviews and a regional participatory workshop to identify the primary opportunities and barriers for animal source food adoption in development programs based in the West African Sahel. The paper argues that more evidence is needed to effectively link the livestock and nutrition sectors.
