How do agro-pastoral policies affect the dietary intake of agro-pastoralists in Niger?

Abstract : We investigate the causal mechanisms underlying the effect of agricultural policies directed toward pastoralist households in Niger on their dietary intake. To do so, we conduct a causal mediation analysis while referring to theoretical agricultural household models. The presumed mediator of interest is the annual profit from pastoral activities. We decompose the total effect of selected policies on pastoralist dietary intake into an indirect effect, i.e., the effect that operates through profits, and a residual direct effect. Using an agro-pastoral survey conducted in Niger in 2016, the effects of extension services associated with better access to markets are found to be channeled through households’ annual profits from cattle and sheep raising, while this is not the case for private veterinary services and low-cost livestock feed programs. Extension services may foster specialization in cattle and sheep raising, which may incentivize households to move toward a nomadic lifestyle and change their food habits and thereby have detrimental consequences on their calorie intake. Besides, other life choices could be spurred or hampered by policies, such as migrations and radicalization.
