This important and timely book provides a rigorous overview of the defining issues presently facing conservation at international level. The author provides detailed coverage of topics ranging from the classification of species right through to access and benefit sharing, drawing on his personal experience at intergovernmental level. Each question is examined through the prism of dozens of treaties and hundreds of decisions and resolutions of the key multilateral regimes, and the law in each area is supplemented by the necessary considerations of science, politics and philosophy--providing much-needed context for the reader.
