UNESCO Expands Heritage Protection in Island Nations as Climate Risks Threaten Traditional Knowledge

“Living heritage is not only cultural memory — for many island communities, it is also a practical system of survival.”

UNESCO is expanding efforts to protect living heritage across Small Island Developing States (SIDS), arguing that traditional knowledge systems are increasingly essential to disaster preparedness and climate resilience as island nations face rising environmental threats.

From the Pacific to the Caribbean, communities are using inherited practices such as cyclone-resistant housing, traditional medicine, oral storytelling, food preservation and weaving not only to preserve cultural identity, but also to respond to increasingly severe climate pressures including rising sea levels, volcanic activity, floods, cyclones and displacement.

UNESCO said these practices, often passed down through generations, represent both vulnerable cultural assets and practical tools for survival, particularly in remote communities with limited access to formal infrastructure.

Small Island Developing States account for less than 1% of global greenhouse gas emissions, yet remain among the most exposed to the consequences of climate change because of their geography, dependence on natural resources and vulnerability to extreme weather events.

In response, UNESCO, with financial support from the Government of Japan, launched a regional project involving communities in Fiji, Tonga, Vanuatu, Belize and The Bahamas to strengthen the role of intangible cultural heritage in disaster risk reduction.

The project focused on documenting community practices, supporting transmission of traditional knowledge and connecting local communities with disaster management authorities so cultural knowledge could be integrated into formal resilience planning.

UNESCO said the approach reflects a broader recognition that living heritage can serve as both a safeguard and a response mechanism during emergencies.On Vanuatu’s Tanna Island, for example, community member Warau Frederick described traditional cyclone shelter construction as both cultural preservation and physical protection.

Vanuatu is among the countries most exposed to climate-related disasters in the Pacific, regularly facing cyclones, volcanic eruptions and displacement pressures. Communities there continue to rely on long-established building methods using local materials and inherited techniques to construct shelters capable of withstanding severe weather.

Frederick said he learned the process from his uncle and chose to build a shelter for his family before cyclone season, reflecting how traditional architecture remains embedded in everyday preparedness.Traditional weaving also remains economically significant in the same communities.

Eva Namri, a community member on Tanna Island and a knowledge bearer of traditional weaving, said the practice serves as a financial safety net during periods of hardship.“Weaving brings a great deal of income to my family,” Namri said. “It supports us whenever we face financial difficulties.

The biggest challenge for weaving comes from natural disasters.”UNESCO said such examples show how cultural practices operate simultaneously as economic resilience tools and heritage systems, particularly where formal income opportunities are limited.

Across the Caribbean, communities participating in the project focused on preserving food systems and traditional medicine as part of local resilience strategies.

In Fiji, where flooding and environmental changes increasingly threaten food security, communities relied on traditional fishing, farming methods and collective cooperation to maintain access to food.

In Vanuatu, people facing repeated displacement from volcanic activity and cyclones used early warning knowledge, gardening systems and traditional housing practices to reduce vulnerability.In Tonga, communities displaced by a volcanic eruption and tsunami emphasized the importance of oral traditions and craft practices not only for cultural continuity but also for mental well-being and livelihood recovery after disaster.

UNESCO said the project also created longer-term institutional foundations by identifying community members to serve as Intangible Cultural Heritage ambassadors, responsible for helping sustain and transmit traditional practices beyond the duration of the program.These local ambassadors were tasked with ensuring knowledge transfer, particularly in communities facing relocation or demographic shifts that risk interrupting intergenerational learning.

For many participants, the initiative also had direct economic implications.Feleti Akauola, a community member from Atata in Tonga, said relocation after disaster created uncertainty over how families could rebuild sustainable livelihoods.

He said guidance from Sitiveni Fehoko, a community trainer and intangible cultural heritage ambassador, helped communities think about traditional knowledge not only as preservation, but as a source of income and long-term stability.

“One of the key aspects of the project was that it strengthened me in many ways,” Akauola said. “It explained ways we could earn a living, especially for those of us who had been relocated. This was very encouraging, and it gave me and my wife the idea to start our work and make a living for our family.”UNESCO said this illustrates how cultural safeguarding increasingly intersects with economic adaptation, particularly in island states where environmental shocks can quickly translate into displacement, unemployment and food insecurity

.The agency has argued that disaster planning should not treat heritage solely as something to be protected after crisis, but as an active component of prevention and recovery strategies.As climate risks intensify globally, UNESCO said living heritage offers continuity that extends beyond formal emergency responses, helping communities retain identity while adapting to rapidly changing environmental conditions.

The organization said the project also raised awareness of vulnerable traditions that may otherwise disappear as migration, urbanization and repeated disasters disrupt local transmission systems.Even in cases of displacement, UNESCO found that communities continued practicing oral traditions, crafts and local environmental knowledge, reinforcing the adaptability of living heritage under pressure.

The initiative aligns with broader United Nations Sustainable Development Goals related to climate resilience, cultural sustainability and inclusive development, particularly in regions where environmental vulnerability and cultural preservation are closely linked.UNESCO said future efforts will continue to focus on integrating heritage protection into national disaster reduction policies while supporting local ownership of cultural safeguarding.

For Small Island Developing States, the agency said, resilience increasingly depends not only on infrastructure and funding, but also on whether communities can retain the knowledge systems that have helped them survive for generations.
