The Kainji Dam across the Niger in Nigeria was closed in 1968. In this book, Wolf Roder evaluates the Nigerian development in areas such as population, agriculture, pastoral nomadism, subsistence fishing, housing and public health, over the past twenty-five years. This study finds that the effects of the man-made lake have, on occasion, been benign. Rather, secular changes have had the largest impact on the Nigerian economy.
