AbstractThe destructive impacts of oil exploitation on the natural environment, which the inhabitants of the Niger Delta depend on for their livelihood, pose major threats to food security. Environmental damage alienates the local people from their ancestral lands and erodes their sources of livelihood. This study examines the effect of oil exploitation on the local people's access to sufficient, safe and culturally acceptable food. The study is based on data collected through interviews with key informants and Focus Group Discussions in the oil communities in Bayelsa, Delta and Rivers States. Environmental and livelihood sustainability are intricately interconnected. They have significant implications for food security of people in the oil-rich region. Nutritional adequacy is a necessary but not a sufficient condition for food security because cultural acceptability is also required. This study addresses the interplay between these factors and their implications for household food security in the Niger Delta.
