SIDS face a complex “polycrisis” of climate change, biodiversity loss, pollution, economic shocks and rising debt burdens, all in a context of weakening multilateralism and geopolitical fragmentation. Their small size, exposure to climate hazards and limited diversification potential, are structural vulnerabilities that limit development opportunities and drive high costs, even where headline income levels appear relatively high. These challenges define the special circumstances of SIDS. At the same time, the extent of their Exclusive Economic Zones (EEZs) make many SIDS large ocean states with unique environmental, cultural and strategic assets.
The Antigua and Barbuda Agenda for SIDS (ABAS), adopted at the Fourth International Conference on SIDS (SIDS4), sets out a comprehensive framework for achieving sustainable development in the decade ahead. The agenda emphasises resilience, justice, partnerships and the need to reform global rules so that they recognise and respond to SIDS’ special circumstances. The ABAS calls for a ’10-year sprint’ with the planet reaching critical thresholds and tipping points, there is a sense of urgency for SIDS to invest in action now that will safeguard their islands for decades to come.
The post‑war liberal international order is increasingly under strain. This shift is deeply consequential for SIDS who have long relied on predictable trade routes and a rules-based multilateral system. It creates both risks and opportunities. There is a risk that their voices are drowned out as multilateral institutions become less relevant. There is an opportunity for SIDS to use digital tools and AI to tell their own stories, generate their own data and shape global narratives on climate, oceans, justice, health and trade.
The SIDS special case for sustainable development has been repeatedly affirmed, yet a question that was repeatedly raised was: “what is the ‘special’ in the special case?” amidst geopolitical competition, shrinking development assistance, and the claims of other groups to special treatment. Speakers stressed that SIDS cannot simply wait for the international system to adapt. They must continue to shape narratives, invest in partnerships that deliver, and be agile in the way they implement the ABAS and other international commitments. They acknowledged the important but changing role of international organisations that support SIDS, as they face deepening global changes.
