Small Island Developing States (SIDS) and AOSIS

Small Island Developing States, or SIDS, are a group of small island and low-lying coastal developing countries that the United Nations treats as a special case. They face similar problems: small size, remoteness, dependence on a few industries, and very high exposure to climate change and disasters. The Alliance of Small Island States, or AOSIS, is the negotiating group through which most of these countries speak together, especially in climate talks.

Why were they given special status?

Think of a small shop on a remote island. It must bring in almost everything by ship, so costs are high. It sells only one or two things, so one bad season can ruin it. A single cyclone can wipe out years of work. SIDS face this at the level of a whole country. A hurricane can destroy a big share of a small island's economy in one day.

Many depend heavily on tourism, fishing or imports of fuel and food. Rising seas threaten their very land. Because of all this, normal measures like income per person do not show how fragile they really are.

Where did the idea come from?

SIDS were first recognised as a distinct group at the UN Conference on Environment and Development (the Earth Summit) in Rio de Janeiro in June 1992. Chapter 17 of Agenda 21, the action plan adopted there, said small island developing states are "a special case both for environment and development". Since then, the world has adopted four action plans for them:

1. Barbados Programme of Action (1994)
2. Mauritius Strategy (2005)
3. SAMOA Pathway (2014), short for SIDS Accelerated Modalities of Action
4. Antigua and Barbuda Agenda for SIDS (ABAS), adopted at the fourth SIDS conference (SIDS4) in Antigua and Barbuda, 27 to 30 May 2024, covering the next ten years

Who are the SIDS?

The UN lists 39 states and 18 associate members of UN regional commissions (territories that are not fully independent UN members) as SIDS. They are grouped into three regions:

• the Caribbean (for example, Jamaica, Barbados, Haiti, Trinidad and Tobago)
• the Pacific (for example, Fiji, Tuvalu, Kiribati, Vanuatu, Palau)
• the AIS region: Atlantic, Indian Ocean and South China Sea (for example, the Maldives, Mauritius, Seychelles, Cabo Verde, Singapore)

Note that some SIDS, like Singapore, are rich. The group is based on shared geography and vulnerability, not only on income.

What is AOSIS?

The Alliance of Small Island States was formed in 1990. It has 39 members, drawn from the Pacific, the Caribbean, the Atlantic, the Indian Ocean and the South China Sea. AOSIS works as a negotiating bloc at the United Nations, above all in climate negotiations under the UN Framework Convention on Climate Change (UNFCCC). The chair rotates among its members.

Because its members are so exposed, AOSIS has pushed hardest for strict warming limits (it championed the 1.5 degrees Celsius goal), for loss and damage funding, and for legal protection of sea zones and statehood.

How does the UN support them?

Several UN bodies have SIDS in their mandate:

• UN-OHRLLS (Office of the High Representative for the Least Developed Countries, Landlocked Developing Countries and Small Island Developing States), set up by the General Assembly in 2001 through resolution 56/227, speaks for SIDS inside the UN system.
• The UN Department of Economic and Social Affairs (DESA) tracks progress on SIDS action plans.
• In August 2024, the General Assembly adopted the Multidimensional Vulnerability Index (MVI). It measures how exposed a country is to economic, environmental and social shocks, not just how rich it is. SIDS pushed for it for years, because many of them are classed as "middle income" and so lose access to cheap loans even though one storm can set them back years. The UN says using the MVI is voluntary.

India's role and Indian examples

India engages SIDS in several ways:

• Forum for India-Pacific Islands Cooperation (FIPIC): launched in November 2014 at Suva, Fiji, with 14 Pacific island countries. Summits have been held in Suva (2014), Jaipur (2015) and Port Moresby, Papua New Guinea (2023), where India announced a 12-point action plan.
• Infrastructure for Resilient Island States (IRIS): launched on 2 November 2021 at COP26 in Glasgow under the Coalition for Disaster Resilient Infrastructure (CDRI), an India-led body. It helps SIDS build infrastructure that can survive disasters.
• Indian Ocean neighbours: The Maldives, Mauritius and Seychelles are SIDS and key partners in India's maritime vision, with development help, disaster response and security cooperation.

India itself is not a SIDS, but its own islands (Lakshadweep, Andaman and Nicobar) face similar climate risks.

Commonly confused concepts

• SIDS vs AOSIS: SIDS is a UN category of countries recognised for special treatment. AOSIS is a political alliance that negotiates together. Most members overlap, but they are not the same list.
• SIDS vs LDCs vs LLDCs: Least Developed Countries (LDCs) are defined by low income and weak development. Landlocked Developing Countries (LLDCs) have no coastline. SIDS are defined by small size, island geography and vulnerability. A country can be in two groups; for example, some Pacific islands are both SIDS and LDCs.
• SAMOA Pathway vs ABAS: SAMOA Pathway (2014) was the SIDS plan for 2014 to 2024. ABAS (2024) is its successor for the next ten years.
• Pacific Islands Forum vs FIPIC: The Pacific Islands Forum is the Pacific countries' own regional group. FIPIC is India's platform for engaging 14 Pacific island countries.

Issues, criticism and the way forward

• Finance access: Many SIDS are counted as middle-income, so they struggle to get cheap loans and grants. The MVI aims to fix this, but it only works if lenders actually use it.
• Debt: Repeated disasters force SIDS to borrow for rebuilding, pushing up debt. Ideas like debt-for-climate swaps and disaster pause clauses in loans are being tried.
• Existential climate risk: Sea-level rise threatens land, fresh water and farming. Adaptation money is still far below needs.
• Small voice: Small populations mean small delegations and limited capacity in long negotiations. Coalitions like AOSIS help, but capacity support is still needed.
• Way forward: Faster emission cuts by major emitters, scaling up adaptation and loss and damage funds, legal certainty on statehood and sea zones, resilient infrastructure (such as IRIS), and full use of the MVI in lending decisions.

Concepts to Know

• Adaptation: Actions that help people live with climate change that is already happening, such as sea walls, early warning systems and drought-resistant crops.
• Loss and damage: Harm from climate change that adaptation cannot prevent, such as land lost to the sea. Countries set up a fund for it under the UNFCCC.
• Associate member of a UN regional commission: A territory that is not a full UN member (for example, some island territories linked to other countries) but can take part in the work of a UN regional commission.
• UNFCCC: The United Nations Framework Convention on Climate Change, the main global treaty for climate negotiations. Its yearly meeting is called the COP (Conference of the Parties).
