Abstract

This study
analyzes the causal and spread effects of extreme flood on food availability
and affordability, as the two dimensions of food security in Nigeria.
Multi-stage sampling procedure was adopted to collect primary data from 420
farming households. Statistical methods, regression model and descriptive statistics,
were used to analyze data. It was found out that household mean food security
index is 0.32 (32%) and it was significantly influenced by flood hazards in the
short run. Results suggest that the flood hazards directly lead to a fall in
the food availability, food consumption and welfare of vulnerable rural
households. This indicates that the more the flood severity the more the food
security challenge among indigenous farming households. Spillover (indirect)
effects of flood hazards show the extent of spread of the hazards in the form
of disease outbreak, increased dependency ratio, mass migration of flood
victims, food scarcity and increase in prices of food stuffs. 

Keywords
