This paper examines the ex-post impact of the combination of cropping- system diversification (CSD) and the adoption of improved maize varieties on child stunting and household nutritional security. To control for selection and endogeneity bias, arising from time-variant and time-invariant individual heterogeneity, the study employs a fixed-effects multinomial endogenous switching regression using large, on a panel data set collected in maize-growing areas of Ethiopia between 2010 and 2013. Results highlight the significant effect of adoption of CSD and improved maize varieties on child stunting; per capita consumption of calories, protein, and iron; and dietary diversity. The greatest impact was achieved when farmers adopted CSD and improved maize varieties jointly rather than individually. Our results are a validation of the need to strengthen smallholder diversification in the face of subsistence production and limited access to food markets. In these scenarios, production of a diversified crop portfolio among low-income rural families should be encouraged, given the limited opportunities for specialization and constrained access to diversified diets through local food markets. Howerver, in the long run, market access to diverse food types is likely to provide more sustainable diet diversification and nutrition.
