FOOD SECURITY IN VULNERABLE COASTAL ZONES IN WEST AFRICA: THE CASE OF GHANA
The combination of increases in flooding and storm surge and sea level rise resulting from climate warming is causing significant damage to coastal communities globally. The vulnerability of coastal communities in Ghana may be exacerbated by inadequate food and other resources which limit community resilience when flooding occurs. And coastal erosion may undermine longer-term livelihoods from fishing, farming, and other sources, limiting households’ economic access to affordable foods. Understanding whether there exist food security differences between coastal versus non-coastal districts in Ghana due to coastal erosion is critical in order to identify factors that can help improve community resilience. This study uses two metrics of food security – food consumption score and cash food expenditures per capita - constructed from a national representative household survey data set for districts located along Ghana’s coast and interior. Using multivariate regression analysis, it was found that household size, education status of household head, employment, welfare, and marital status were strongly associated with household food security in the ways typically found in the food security literature. The innovative findings are of a strong negative correlation between location in a coastal district, but a positive correlation between prior (1974-2005) coastal erosion rates, and a household’s food consumption score.
