Effective protection of the marine and terrestrial environment increasingly requires cooperation between neighbouring States, international organizations, government entities and communities within States. This book analyses key aspects of transboundary environmental law and policy and their implementation in Asia, Australasia and Australian offshore territories, and surrounding areas beyond national jurisdiction including Antarctica. It discusses the potential for implementing key transboundary environmental mechanisms such as the 1991 Convention on Environmental Impact Assessment in a Transboundary Context (Espoo Convention) and its 1997 Protocol on Strategic Environmental Assessment (Kiev Protocol) in Australia and Asia drawing on experience from other regions and the potential application of these agreements to all UN member states. The book makes an innovative contribution to research in the area of transboundary environmental governance particularly as it applies to Asia, Australasia and international areas, supplementing similar research which has predominantly focused on Europe and North America.
