The book is a lucid study of the relationship between petroleum exploitation and the dynamics of labour force within the framework of population and environment inter-relationship. It examines the impacts of petroleum exploitation activities on the physical environment of the oil-rich Niger Delta Region, and the resultant impacts on spatio-temporal dynamics of occupations, labour input and output, and multiple occupations of the rural population. The study focuses on Delta, one of the oil-producing states of the region. The book would be of immense benefit to scholars in diverse disciplines including geography, population, environmental studies, rural development and planning, economics and manpower planning.
