Five reasons why Small Island Developing States are bigger than we think

The fourth International Conference on Small Island Developing States is not only a pivotal event for those nations, but also for the global community.

Ahead of attending, Karina Barquet reveals five compelling reasons why these states, despite their size, are crucial to worldwide climate resilience and biodiversity strategies.

From 27 to 30 May, over 2,000 delegates will convene in Antigua and Barbuda for the United Nations-led fourth International Conference on Small Island Developing States (SIDS4). This gathering, the first of its kind in ten years, occurs at a crucial time for these island nations.

Since their last meeting in Samoa in 2014, the challenges faced by SIDS have escalated severely. The growing impacts of climate change and rapid biodiversity loss have magnified their struggles, highlighting the pressing need for global attention and action.

Why are SIDS so important?

Here are five reasons why the role of SIDS extends far beyond their geographical boundaries:

1. SIDS are vital biodiversity hotspots.

SIDS host 40% of the world’s coral reefs, which are among the most biodiverse ecosystems globally. Occupying less than 0.5% of the Earth’s land surface, these islands are believed to support 20% of its terrestrial biodiversity, with many species unique to their locales.

Despite their ecological wealth, SIDS face numerous environmental challenges, including coral bleaching from warmer seas, coastal erosion, salinization and the threat of invasive species.

2. SIDS are disproportionately affected by climate change and biodiversity loss.

Positioned at the forefront of the climate and biodiversity emergencies, island states bear the brunt of rising sea levels, coral degradation and increasingly severe weather events. Caribbean islands, for instance, are seven times more likely to be hit by hurricanes compared to larger nations.

These environmental threats are interconnected, as the loss of critical ecosystems such as coral reefs, mangroves, and seagrass beds heightens their vulnerability to natural disasters.

3. The unique economic circumstances of SIDS must be considered.

SIDS are among the world’s most indebted nations, often due to factors beyond their control. The high costs associated with their isolation and small size mean that major investments, like constructing an airport, can amount to the entire GDP of a country. Frequent hurricanes exacerbate their economic challenges, with borrowing costs substantially higher than those in Europe or the USA.

The upcoming conference will emphasize strategies for fostering sustainable and diversified blue economies and improving financial accessibility.

4. SIDS are crucial custodians of both land and ocean.

SIDS oversee marine areas often 28 times greater than their land mass, making them pivotal in managing vast ocean expanses. This stewardship underscores the importance of considering these nations as “Large Ocean States”, reflecting their significant role in marine biodiversity protection, among others.

In many cases, traditional island cultures offer a deep understanding of marine and terrestrial ecosystems that are not well known to scientists. The importance of Indigenous and local knowledge in managing and conserving marine resources is now increasingly recognized, for example in the new BBNJ (Biodiversity Beyond National Jurisdiction) agreement. Institutions like the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services also advocate for integrating this knowledge into broader ecosystem assessments.

5. SIDS are exceptionally innovative and resourceful.

Despite a modest population of just 65 million, SIDS have a significant impact on international negotiations. They played a key role in establishing the 1.5°C target in the Paris Agreement and are leaders in advancing understanding of the ocean’s influence on climate dynamics.

SIDS are often at the forefront of climate change adaptation, testing innovative approaches that benefit not only themselves but also the rest of the world. These efforts, capable of generating new business opportunities, are crucial and require financial support to realize their full potential.

SEI at SIDS4

At the upcoming conference, SEI will collaborate with local experts to explore innovative climate change adaptation approaches that combine nature-based solutions with technologies such as gridless and multiuse systems. Some partners are already involved in joint activities, such as the new SEI-led project Resilient Coasts – Caribbean Sea.

In addition to exploring these approaches, I will participate in the conference to monitor the negotiations on a new programme of action for SIDS and engage with like-minded organizations and individuals. SEI will host a side event titled Unlocking multifunctional solutions: building climate resilience and sustainable blue economies, in collaboration with several regional and international partners, including the Dominican Institute of Integral Development and the Ministry of Economic Development of Grenada.

As I look forward to contributing to this dialogue, I am hopeful that the conference will not only address the immediate needs of the 39 participating island and low-lying states but also enhance global understanding of why their fate is intrinsically linked to ours.
