Abstract

Ecosystem-based management recognizes the variety of spatial interactions within an area, including humans, rather than considering single issues, species, or ecosystem services in isolation. To implement such an approach, a diversity of social, economic and environmental information from all existing sources is needed in a format that is both appropriate and accessible to all stakeholders. A participatory geographical information system (PGIS) approach was employed in the transboundary Grenadine Islands as a conceptual framework to integrate, analyze and share multi-disciplinary and multi-knowledge information to assist ecosystem-based management. The resulting Grenadines Marine Resource and Space-use Information System (MarSIS) brings together a variety of information and can be used to uniquely identify areas important for conservation and livelihood, ultimately assisting ecosystem-based management and transboundary marine spatial planning. Here the potential of the MarSIS is showcased using the newly established Sandy Island Oyster Bed Marine Protected Area (SIOBMPA) in Carriacou, Grenada as a case study. The utility of PGIS specifically the ways in which information can be brought together, visualized and analyzed to create practical baseline inventories on marine habitats, resources and associated human activity of the SIOBMPA is illustrated.
