’This book from Simone Borg is a much needed and highly recommended study on conservation on the high seas and harmonizing international regimes for the sustainable use of living resources. This publication is very topical considering the continuous over-exploitation of the living resources. It is a very exhaustive study of many international instruments, the most importantly the 1982 The United Nations Law of the Sea Convention. The author in an admirable manner linked the issue of the conservation of living resources on the high seas to the fundamental principles underlying modern environmental law such as the precautionary principle. The unique feature which sets this book apart from the other similar publications is that it is firmly entrenched in general international law, i.e. deals in a very erudite manner with the issues of fragmentation and harmonisation of international law in the context of conservation. This book will appeal not only to the experts on the law of the sea, but also to general international lawyers.’- Malgosia Fitzmaurice, Queen Mary, University of London, UK
