Agriculture is central in order to achieve nutrition goals through the provision of food, energy and essential micronutrients for the physical and mental development of humans. Dietary diversity is a good indicator of human food security status. Using a dataset obtained from the World Bank’s Living Standards Measurement Study—Integrated Surveys on Agriculture (LSMS-ISA), this paper examines the linkages between crop diversity and food security (measured as dietary diversity) among farming households in Nigeria using ordinary least squares, Poisson regression, and instrumental variables (IV) Poisson regression to estimate the relationship. In addition, we investigate the determinants that lead to the consumption of each food groups considered for generating dietary diversity using a logit regression model. The results show that food expenditure, asset ownership and location of households are the key factors driving the types of food consumed by the households. Furthermore, increased food expenditure and access to credit were found to positively influence food security. The result established a positive and significant relationship between crop diversity and dietary diversity. Our findings call for more attention to diet diversity, as well as the need to harmonize the roles of rural income improvement, especially through non-farm livelihood diversification in tackling multiple nutritional deficiencies in Nigeria.

Issues related to malnutrition, broadly defined, have received a growing attention in recent years, not only in connection with the Sustainable Development Goals but also recently with the unprecedented Covid-19 pandemic. At the same time, there exists a complex interaction between institutions, capital flows, and food and nutrition security that has received less attention in the relevant literature. In this paper we estimate a series of dynamic panel data models to examine the impact of institutional quality and capital flows on food security, nutrition security and undernourishment by using panel data for 25 SSA countries over the period 1996 to 2018. One of the key contributions of the paper is the use of both aggregate and disaggregated capital flows to examine the impact on both food and nutrition security, a dimension that has been surprisingly neglected in most of the relevant literature. We combine this with the interaction of various types of capital flows with an institutional quality index we constructed from various governance indicators to examine the impact of institutions on the overall nexus. Finally, we examine the impact not only on food and nutrition security but also on undernourishment. Our findings clearly demonstrate the importance of a heterogeneity approach and reflect on earlier work regarding the role of institutional quality in the overall nexus between external capital flows and various measures of food and nutrition security which leads, and as expected, to an interesting variation in the results obtained, depending on the type of capital flows and the interaction with the governance indicators.

The paper focuses on the impact of food aid and governance quality (the latter disaggregated in different components) on both food and nutrition security in the SSA region and for a sample of 25 countries over the period 1996 to 2018. The main novelty and contribution of the paper in the relevant literature is by providing macro-level evidence in the SSA region to complement country-specific evidence in this research area. We also use different food and nutrition security outcome measures, which include the average value of food production, average dietary energy supply adequacy, and prevalence of undernourishment. Furthermore, we combine the above with the use of both aggregated and disaggregated governance indicators to examine the impact of governance quality on the outcome variables. We find evidence of a robust relationship between food aid, governance quality, and food and nutrition security outcomes by employing the GMM estimator. We also find that food aid increases food and nutrition security while it reduces undernourishment. Among the various governance quality indicators we have employed, the control of corruption and political stability show a significant relationship with the measured outcomes. However, the composite governance index and food aid jointly have no significant effect on food security, but they significantly increase nutrition security and reduce undernourishment across the various empirical models we have employed in our empirical analysis. An important policy lesson emanating from our empirical findings is that controlling corruption and maintaining political stability may have significant implications for enhancing the impact of food aid on food and nutrition security in the region.
