Although there exists considerable evidence assessing the effectiveness of various livelihoods interventions and other social protection programmes, as well as some evidence on the effectiveness of various direct nutritional interventions, little research directly assesses how an integrated livelihoods and nutrition programme might compare with livelihoods support alone. There are several reasons why the combination of nutrition and livelihoods support may have nutritional benefits over and above livelihoods support only. First, a key constraint to improved nutritional status may be insufficient knowledge of appropriate infant and young child feeding practices (for example, the appropriate duration of exclusive breastfeeding, the appropriate frequency and diversity of child feeding thereafter, etc.). If this is the case, then improving income alone will not necessarily lead to improved feeding practices. Second, there may be synergies between the two types of support. For example, even if a mother's knowledge of infant and young child feeding practices improves, she may still need access to sufficient resources for undertaking those practices (such as income to purchase the recommended types of food), which can be facilitated through a livelihoods intervention. Third, there may be other dynamics shifted through the direct nutrition intervention that mediate how the livelihoods intervention affects nutritional status. For example, if a direct nutrition intervention targeting women improves women's bargaining power within the household, and if women tend to prefer devoting more resources to young children's nutrition (e.g., Quisumbing and Maluccio 2003), the result may also be larger impacts on nutritional status than livelihoods support alone.
