Research, assessment and management on the Mascarene Plateau: a large marine ecosystem perspective

Management of marine resources over the large ocean areas provides a great challenge, albeit one with hope for sustainable governance. Despite extensive studies in many of these large ocean areas, the interaction of physical and biological processes in large shallow mid-oceanic areas, such as the Mascarene Plateau in the Western Indian Ocean, is not yet well enough understood to influence management practices. The Mascarene Plateau arches across the Western Indian Ocean from the Seychelles down to Mauritius, with water depths up to 100 m. Such a large shallow mid-oceanic area supports a wide diversity of ecosystems with potential for exploitable resources. A recent marine research programme by the Royal Geographical Society of London led to the establishment of a research framework for long-term research and assessment of the Mascarene Plateau. This paper presents an extension to this approach, with a particular focus on the management, governance and socio-economics of this area.
