The Ocean is profoundly influenced by a number of factors, including climate change, the subsequent sea-level rise and the associated impact on biogeochemical processes. The implementation of marine biomass, energy sources and mineral exploitation in the context of globalisation have also influenced the ocean economy. In this framework, a wide range of crucial issues has emerged calling for close co-operation between science and policy. International policy, sustained by the law of the sea, has made strong, but insufficient efforts to provide useful tools to deal with these considerations. This topical book examines ocean governance from a perspective which has taken shape as a result of efforts made in the international arena. Adalberto Vallega offers a unique view, considering the ocean as a spatial complex system which cannot be described in detail but must be represented as a whole and argues that scientific approaches must change to achieve progress and co-operation between science and policy. The text focuses on the cardinal aspects and issues of ocean governance and studies ecological, economic and legal management dimensions in their proper context. Making use of an interdisciplinary approach and non technical language, this book will be a useful tool for understanding the present conditions of the ocean and the design of its future. It will be an invaluable resource for professionals and advanced students alike.
