This paper describes some of the most challenging ocean inequities faced by SIDS, as well as successes in ‘turning the tide’ – where SIDS have already challenged unfair structures and practices and developed their own solutions. Recommendations for development partners to enhance ocean equities and deliver for SIDS and for oceans include ensuring equity issues are at the centre of the international agenda on the blue economy, supporting SIDS to diversify their ocean economies and expand access to new technologies, and supporting SIDS on negotiations and the implementation of international agreements. For the private sector and impact investors, there is an opportunity to help SIDS generate value through sustainable and equitable use of their ocean resources.
