The current global food crisis presents a puzzle, thus raising concerns among researchers and policymakers. A number of causes have been identified. However, the relative importance of each factor is still uncertain. In this study, the link between food prices and the various interconnected factors are modelled. The study also quantifies the current and future poverty impacts of rising food and energy prices under a number of scenarios. In general, it was observed that rising food and energy prices have adverse effects on the Nigerian economy and household welfare. Thus, the need for appropriate policy responses cannot be overstressed.
