Household food insecurity and cooking energy access in Nigeria: A panel data approach

Access to sources of cooking energy has potential impacts on food security, however, there is a paucity of information and empirical evidence on their linkages. This study sought to ascertain the impacts of access to cooking energy on household food security in Nigeria, using the nationally representative Living Standards Measurement Study data. The data covered the period 2010/2011 to 2015/2016. The Household Dietary Diversity Score (HDDS), and the Household Food Insecurity Access Scale (HFIAS) were used to measure household food security, while the major cooking fuel type utilized by households was used as a proxy for cooking energy access. To unravel the effects of access to different cooking energy sources on food security, inferential analysis was conducted using the Generalized Estimating Equations (GEE). The findings of the study revealed that traditional/biomass (firewood, grass and charcoal) cooking energy sources are still widely used by households across Nigeria. The empirical analysis showed that households that use transition and clean cooking energy sources were eating more diverse diets than those that use biomass. Furthermore, households using clean cooking energy sources had lower HFIAS than those using biomass. It is imperative that more households in Nigeria should have improved access to cleaner sources of cooking energy to reduce carbon emissions and enhance health outcomes, and food and nutrition status. This will significantly improve the national food security outlook, and foster the attainment of national and SDG (2 and 7) goals.
