Tropical coastal ecosystems in the Western Indian Ocean region are under enormous pressure from increasing resource use, environmental degradation, and global climate change. This impedes their huge potential for mitigating the effects of climate change and their provision of a wide range of economic and non-monetary values to local communities. PAMO provides policymakers with decision support tools to improve the implementation and planning of Nature-based Solutions (NbS) and to identify needs and scenarios of an optimised use of local ecosystems for and with local communities in the Western Indian Ocean region. The primary outcome of this project is the development of a decision support system that will facilitate the direct engagement between local decision makers and local communities. The project aims to produce both a framework for local policymakers and coastal communities which fosters a shared understanding of the role of the interconnectedness of NbS as socio-ecological systems as well as concrete examples of pilot studies.
