Small Island Developing States, or SIDS, are a group of 38 island and low-lying coastal countries that face unique social, economic, and environmental challenges. These states share similar characteristics such as small populations, limited resources, remoteness, susceptibility to natural disasters, vulnerability to external shocks, excessive dependence on international trade, and fragile environments.
Key Characteristics of SIDS
SIDS have several defining features that set them apart from other developing countries:
- Small population: Most SIDS have populations under 1.5 million, with some as low as a few thousand.
- Limited land area: SIDS are typically small in land size, often less than 1,000 square kilometers.
- Geographic isolation: Many SIDS are located far from major markets and trade routes.
- Narrow resource base: SIDS have limited natural resources and arable land.
- Vulnerability to climate change: Rising sea levels and more frequent extreme weather events pose existential threats to many SIDS.
- Economic volatility: SIDS economies are often dependent on just a few sectors like tourism and agriculture, making them vulnerable to external shocks.
Examples of SIDS
SIDS are located across three geographic regions – the Caribbean, the Pacific, and the Atlantic, Indian Ocean, Mediterranean and South China Sea (AIMS). Some examples include:
- Caribbean: Jamaica, Trinidad and Tobago, Bahamas
- Pacific: Fiji, Samoa, Vanuatu
- AIMS: Maldives, Seychelles, Comoros
Climate Change Impact on SIDS
Climate change poses the single greatest threat to SIDS. The 2022 IPCC report highlighted that many SIDS could become uninhabitable by 2100 due to rising seas, with islands like Kiribati and Tuvalu at risk of complete submersion. Key climate vulnerabilities faced by SIDS include:
- Sea level rise, coastal erosion and flooding
- Damage to coral reefs and fisheries
- Saltwater intrusion into freshwater aquifers
- Increased intensity of tropical cyclones
- Prolonged droughts and reduced food security
Economic and Social Challenges
In addition to their environmental fragility, SIDS also grapple with economic and social development challenges:
- High cost of imports and limited export base
- Dependence on foreign aid and remittances
- Brain drain and shortage of skilled labor
- High unemployment, especially among youth
- Inadequate healthcare and education services
Biodiversity in SIDS
Despite their small land area, SIDS are home to a wealth of biodiversity, with many species found nowhere else on Earth. However, this biodiversity is under threat from climate change, habitat loss, and invasive species.
- SIDS are home to 20% of all plant species and 12% of all animal species.
- The Caribbean islands alone have over 13,000 plant species, of which 6,500 are found nowhere else.
- In the Pacific, 50% of bird species and 90% of reptile species are endemic.
Cultural Heritage and Traditional Knowledge
SIDS have rich cultural heritages and traditional knowledge systems that have evolved over centuries of living in harmony with their unique environments. This knowledge is vital for climate adaptation and sustainable development.
- In the Pacific, traditional agroforestry systems like the “taro-based multistorey system” in Vanuatu help maintain soil fertility and biodiversity.
- In the Caribbean, the Kalinago people of Dominica have used traditional building techniques to create hurricane-resistant homes.
- The Maldives has a long history of using traditional ecodesign techniques like “fengolu” thatched roofs and coral stone walls for climate-resilient construction.
Sustainable Tourism in SIDS
Tourism is a major economic driver for many SIDS, but it can also put pressure on fragile ecosystems and local communities. Sustainable tourism practices are crucial for balancing economic benefits with environmental and social sustainability.
- In Fiji, the “Duavata Sustainable Tourism Collective” brings together local communities, tourism operators, and conservation groups to promote sustainable tourism practices.
- The Caribbean Tourism Organization has developed a “Caribbean Sustainable Tourism Policy Framework” to guide sustainable tourism development in the region.
- In the Seychelles, the “Seychelles Sustainable Tourism Label” certifies hotels and tour operators that meet sustainability criteria.
Renewable Energy in SIDS
Transitioning to renewable energy is a key priority for SIDS to reduce their dependence on imported fossil fuels, improve energy security, and mitigate climate change.
- The Maldives has set a target of becoming carbon neutral by 2030, with plans to generate 60% of its electricity from solar power.
- Barbados has a target of generating 100% of its electricity from renewable sources by 2030, with a focus on solar and wind power.
- The Pacific Island Countries have set a collective target of generating 50% of their electricity from renewable sources by 2030.
International Efforts to Support SIDS
Recognizing the unique vulnerabilities of SIDS, the international community has taken steps to provide targeted assistance:
- The SAMOA Pathway, adopted in 2014, provides a framework for sustainable development in SIDS.
- The UN established the SIDS Accelerated Modalities of Action (SAMOA) Pathway to mobilize support.
- The Green Climate Fund aims to allocate 50% of adaptation funding to SIDS and LDCs.
- Sustainable development partnerships like SIDS DOCK focus on transitioning SIDS to renewable energy.
SIDS by the Numbers
| Indicator | Value |
| Number of SIDS | 38 |
| Total population | 65 million |
| Median GDP per capita (2023) | $11,136 |
| Median contribution of tourism to GDP | 30% |
| Population in low elevation zones | 29% |
| Renewable energy as % of power supply | 28% |
Small Island Developing States face a complex set of challenges, but they are also taking proactive steps to build resilience and chart a sustainable future. By leveraging their unique natural and cultural assets, promoting sustainable tourism and renewable energy, and working in partnership with the international community, SIDS can overcome their vulnerabilities and achieve their development goals.
