Climate variability and household food insecurity in Nigeria 1: Università Ca’ Foscari Venezia, Venice, Italy; 2: Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC), Venice, Italy; 3: Grantham Research Institute on Climate Change and the Environment, London School of Economics and Political Science (LSE), London, UK This paper examines the impacts of climate extremes and variability on food security in Nigeria, focusing specifically on the aspect of households’ access to food. Employing high-resolution climate data and five waves of household-level surveys from 2010 to 2024, we analyse how temperature and precipitation extremes and climate anomalies affect food security indicators. In Nigeria, temperatures have exhibited a rapid increase over recent decades, accompanied by an overall negative trend and substantial variability in annual precipitation. Moderate and severe food insecurity have substantially increased during the study period, with moderate food insecurity being highly prevalent nationwide. By using three different measures of food security - the Household Dietary Diversity Score (HDDS), the Food Consumption Score (FCS), and the Food Insecurity Experience Scale (FIES) - different aspects of households’ access to sufficient and nutritious food are analysed. Employing linear regression models, we find that climate extremes significantly negatively affect food access in Nigeria, with pronounced effects on female-headed and rural households. This study contributes to an improved understanding of the interconnections between climate change and food insecurity, emphasising the importance of policies directed at enhancing the resilience of households and agricultural systems to the adverse impacts of climate change. | |
