The cross-border nature of the Western Indian Ocean and the increasing challenges stemming from unsustainable ocean use, marine pollution and climate change, require harmonised and concerted approaches. This side event will showcase regional and national efforts that promote integrated ocean governance and an inclusive and sustainable Blue Economy, highlighting the connection between local and regional efforts. It will showcase how regional dialogues such as the Growing Blue Conference series hosted by Mozambique allow for exchange of lessons and partners and how multi-stakeholder initiatives such as the Our Blue Future Alliance can support harmonised approaches, technical guidance and financing to local Blue Economy transition. It will also present progress on blue economy efforts from countries in the region; discuss the role of innovative financing mechanisms for regional, national and local action and how to scale and catalase community-driven blue economies across the region through incubation support. The event will conclude with a call for action on how further collaboration can leverage sustainable ocean governance and blue economy solutions in the WIO region.
