This book brings together contributions on the challenges of the environment, agriculture and cross-border migrations in Africa; key areas that have become critical for the continent's development. The central theme running through these contributions is that Africa's development challenges can be attributed to its human and natural ecology. Contrasted with the Cold War epoch, current developments have ushered us into a world of long and uncertain transitions characterized by a search for new pathways including investment in large-scale agriculture by big finance, attempts to revitalize existing agriculture and reworking of social policy. A major twist relates to environmental questions, especially climate change and its global effects, leading to all forms of cross-border migrations and the emergence of new areas of strategic interest such as sub-regional developments as in the Gulf of Guinea. This book provides some intellectual clues on how to interpret these emerging predicaments and chart a way forward into a new era for Africa.
