This book (published in French) consists of nine articles written by environmental lawyers from the region, regrouped around three themes: Chapter I deals with “convergences and divergences of national legal frameworks”, and provides illustrations from a number of countries and subjects; Chapter II considers a selection of legal frameworks for three types of ecosystems (forests, a river basin, and marine and coastal areas); Chapter III considers the implementation of international law and regional integration, as well as the revised African Convention on the conservation of nature and natural resources as a new framework for integrated development of environmental law in Africa. An introduction and a conclusion place these contributions in their international and regional context. The publication is the result of a joint UNEP-IUCN project.
