SDG14 is one of the most ambitious of the 17 SDGs particularly in terms of the accelerated time frames for achieving several of the targets. Successful implementation of SDG14 requires replication and rapid scaling up of proven strategic approaches that can deliver on one or more SDG14 targets. Drawing from the UNDP/GEF International Waters and Biodiversity portfolios, this side event will present a series of short ‘case studies’ highlighting such proven approaches that have succeeded in reversing large scale dead zones, moved global tuna stocks towards sustainability, reduced the impacts of shipping on the marine environment, and introduced integrated, ecosystem-based approaches to sustainable ocean and coastal management at both local and multi-country scales. Speakers will highlight the strategic planning and other ocean policy and management tools and methodologies used, lessons learned and opportunities for replication and upscaling.
