High Seas Governance: Gaps and Challenges identifies gaps in and challenges to the existing legal regime in the protection and preservation of the marine environment of the high seas, including sensitive marine areas. The gaps identified in the book include the failure of liability and compensation schemes to cover pollution of the high seas and the fact that no state has the responsibility to clean up pollution of the high seas. One common theme of the book is that it is necessary to identify a state other than flag states, port states or coastal states, which should have an obligation to exercise jurisdiction and control over certain activities on the high seas.

This study examines the shipmaster’s duty to render assistance at sea under international law. This duty is assessed in the light of contemporary challenges posed by the phenomenon of irregular migration by sea, a problem which has intensified in recent years. The approach undertaken gives special emphasis to the shipmaster’s responsibilities in rescue operations, and his role in the fulfilment of States’ international obligations in the rendering of assistance.
