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.

For decades, women in fishing communities along Lake Victoria were expected to stay on shore, selling fish rather than catching them. In Kagwel village in Kenya’s Kisumu County, stepping into a fishing boat was seen not only as unusual but as a violation of deeply rooted social beliefs.

That changed in 2002 when Rhoda Ongoche Akech, then a 39-year-old mother of seven, decided to enter the lake herself.At the time, Akech had spent years working as a fishmonger, buying fish from male fishermen and reselling them in local markets.

But rising costs for fish purchases, cooking oil, firewood and transport were reducing her earnings and making it harder to support her family.“People were alleging that when women go into the waters accompanied by men, they would engage in sexual intercourse,” Akech, now 61. She said community members initially treated her decision with suspicion, but after realising she was determined to learn fishing rather than challenge morality, opposition gradually faded.

Her decision followed an encounter in 2001 when women from neighbouring Homabay County came to Kagwel and began fishing. Watching them convinced her that the work was possible despite local resistance.“I sought the help of two young men by then to assist me with fishing as I learned,” she said.The cultural restrictions around women fishing in Lake Victoria communities are rooted in longstanding beliefs tied to gender and ritual purity.

According to Kagwel village elder William Okedo, one of the strongest taboos concerned menstruation.“It was believed that if women went into the lake while on period, they would scare away the fish and that would cause losses to people who are fishing,” Okedo said.The restrictions extended to men as well. Fishermen were traditionally discouraged from having sexual relations with their wives the night before fishing trips, based on beliefs that it would reduce their catch.

For 16 years, Akech remained the only woman fishing regularly in Kagwel, working alone among male crews.It was not until 2018 that another woman joined her. Faith Awuor Ang’awo, a 37-year-old mother of four, had also been working as a fishmonger and was facing similar financial strain.“My husband refused the idea at first,” Ang’awo said, citing fears of social backlash from the fishing community.

“But later on allowed me to join Rhoda.”In 2020, Dorcas Awiyo, then a 22-year-old mother of three, followed. Her husband, himself a fisherman, initially opposed the decision but later agreed after the family’s need for additional income became more urgent.“At first, my husband was not receptive to the idea, but later on allowed me,” she said.By 2022, when Janet Ndweyi joined the group, resistance had largely disappeared.

“I didn’t face any challenge or receive any warning when joining them because the community around was used to seeing Rhoda and Faith fishing,” Ndweyi said.Without a husband to support her and with fish trading becoming less profitable, fishing offered her a more stable income. She now uses her earnings to pay college fees for both of her children.

“Through fishing, I am able to cater for my household’s basic needs and also pay for children’s school fees that are in college,” she said.Economic necessity has been the strongest force behind the social shift.According to Wilson Onjolo, fisheries officer for Seme subcounty, boat owners at Kagwel Beach can earn between 6,000 and 8,000 Kenyan shillings ($46 to $62) on productive days. Crew members earn between 500 and 800 shillings ($3.88 to $6.20), while traders such as fishmongers may earn up to 1,000 shillings ($7.75).

That compares favourably with the roughly 500 shillings women like Akech earned daily when they relied solely on fish trading.Village elder Okedo said the economic pressure facing households has made communities more willing to reconsider long-held norms.“This is all because of economic hardships that the community is facing; it is pushing women to break the taboo,” he said.

Fisherman Dalmas Onyango said most male fishermen now support women entering the trade.“The majority of my fellow fishermen now support their decision to fish,” he said, adding that changing economic realities have made old restrictions less practical.At the same time, the lake itself is becoming less reliable.

Lake Victoria, which supports more than 42 million people for food, employment and drinking water, is under increasing pressure from overfishing, pollution, invasive species and climate change. Annual harvests remain around one million tonnes, but per capita catch rates have declined significantly.Akech said she has seen the change directly over the past two decades.

The amount of fish she catches today is noticeably lower than when she first entered the lake in 2002.Chris Mutai, senior meteorologist in charge of the Kisumu meteorological station, said rising water temperatures are contributing to the decline by encouraging algae growth and reducing oxygen levels in the lake.

“To reverse this, people should keep off riparian land to allow undergrowth that will serve as the breeding ground of fish, and avoid pollution of the lake that traps more heat than plain, clear water,” Mutai said.He warned that temperatures could rise by another 0.5 degrees Celsius over the next 10 to 20 years, reaching between 29.5C and 31C.

Without stronger environmental controls, including protection of riparian zones and regulated fishing, fish stocks are expected to continue falling.Weather forecasting has become increasingly important for fishing communities. Mutai’s office distributes five-day forecasts through WhatsApp groups and local government channels, helping fishermen and fisherwomen prepare for dangerous lake conditions.

Despite their success, Akech and her team still operate in a legal grey area.Susan Claire, acting director of fisheries and blue economy for Kisumu County, said women officially participate as boat owners and fish traders, but not as night fishermen or crew members.“We have women who own boats and women traders, but they are not involved in night fishing or as boat crew members,” Claire told Al Jazeera.

That leaves women like Akech without formal recognition or equal access to support available to male fishermen.However, Christopher Aura of the Kenya Marine and Fisheries Research Institute said in 2023 that Lake Victoria had more than 47,000 fishermen, including 1,000 women, suggesting official county records may not fully reflect women’s participation.

Claire acknowledged that declining fish stocks remain a major concern and said the county is working with meteorological services and Beach Management Units to improve awareness, climate adaptation and enforcement against illegal fishing.For Akech, the debate is less about recognition than survival.She continues to leave before dawn with the same determination that first took her to the water more than two decades ago.

Some days the catch is poor, and the income barely covers the effort. On better days, it is enough to keep going.The lake has changed, but so has the community around it.

For nearly two decades, Tim Friede, a 58-year-old resident of Wisconsin with no formal scientific training, deliberately subjected himself to hundreds of snakebites and venom injections in an effort to build immunity that could contribute to the development of a broad-spectrum antivenom.

His self-directed experiment, conducted largely in the basement of his home, has now drawn scientific attention as researchers attempt to translate his immune response into a scalable medical solution.

Friede reported that his actions were motivated by the global burden of snakebite envenoming, which accounts for an estimated 138,000 deaths and around 400,000 cases of permanent disability or disfigurement annually. Available data indicate that as many as 5.5 million people are bitten by snakes each year, with the majority of cases occurring in low-income regions of Asia and Africa where access to timely treatment remains limited.

According to Friede, the process began in 2001 with controlled self-injections of diluted venom mixtures. Over time, he escalated exposure by allowing venomous snakes to bite him directly, typically on the forearm or fingers. The repeated exposure nearly proved fatal on multiple occasions, resulting in severe physical harm including the risk of limb loss and at least one episode that led to a coma.

Friede stated that he was aware of the risks involved but continued due to the lack of effective and widely accessible treatments for snakebite victims. “People said I was crazy,” he said, adding that some individuals attempted to dissuade him. He maintained that his actions were driven by frustration over preventable deaths in vulnerable populations.

His efforts have since intersected with formal research through his association with Centivax, a California-based biotechnology company working to develop a near-universal antivenom. The company is focusing on antibodies derived from Friede’s immune system, which were developed through repeated exposure to a wide range of snake venoms.

Jacob Glanville, chief executive of Centivax, said Friede had been exposed to venom from highly lethal snake species, describing the toxins as potent enough to kill large animals under normal circumstances. A study conducted last year found that replicated antibodies based on Friede’s immune response were capable of neutralizing toxins from 19 species within the elapid family.

This group includes a significant proportion of medically important venomous snakes such as cobras, mambas, taipans, coral snakes and kraits.The findings suggest potential for broader application compared to conventional antivenoms, which are typically species-specific and require precise identification of the snake responsible for a bite.

This limitation has long complicated treatment, particularly in regions with diverse snake populations and limited diagnostic resources.Centivax plans to begin trials of the experimental antivenom on animals in Australia, with initial testing focused on pets. Human trials would follow pending further validation of safety and efficacy.

Friede said he hoped the research would demonstrate that his prolonged exposure to venom had not been in vain.The urgency of developing more effective antivenoms is underscored by environmental and demographic trends. Studies indicate that climate change may increase interactions between humans and snakes as rising temperatures alter the habitats and behavioral patterns of both.

Warmer conditions can expand the active range of snakes and shift human activity patterns, raising the likelihood of encounters.Recent incidents reflect this trend. In California’s Ventura County, six people have reportedly been bitten by rattlesnakes during an unusually warm spring season.

While isolated, such cases are consistent with broader projections that environmental change may elevate snakebite risk in certain regions.Despite the scale of the problem, global antivenom supply remains uneven. A 2021 review of antivenom resources identified insufficient manufacturing capacity to meet clinical demand, particularly in regions where production infrastructure is limited.

The report highlighted gaps in distribution systems and funding constraints, noting that antivenoms are often unavailable or unaffordable in the areas where they are most needed.Friede’s case represents an unconventional approach to a longstanding public health challenge.

Researchers emphasize that snakes themselves are not inherently aggressive toward humans and typically bite only in self-defense. From an ecological perspective, snakes play a critical role in maintaining balance within ecosystems, including controlling pest populations.Scientific understanding of venom has evolved significantly, with researchers viewing it as a complex product of evolutionary adaptation.

Venom systems have developed over more than 100 million years, predating modern mammals and reflecting highly specialized biological functions.Friede described a personal fascination with snakes that persisted despite early encounters. He said that even as a child, after being bitten by a non-lethal species, he did not develop a fear of them.

Over time, this interest evolved into sustained interaction and eventually into his self-imposed immunization effort.He characterized snakes as biologically remarkable, noting their ability to survive without limbs and to produce highly potent venom. His prolonged exposure to these animals, he said, fostered both respect and curiosity, even as it carried significant personal risk.

The broader implications of his experience are now being evaluated within a formal scientific framework, with researchers attempting to determine whether his antibodies can be adapted into a standardized treatment capable of addressing a wide spectrum of snakebite cases.

In the high-altitude grasslands of Colorado, known for their dense summer blooms of corn lilies, aspen sunflowers and sub-alpine larkspur, a decades-long ecological experiment is providing new evidence of how climate change is altering fragile mountain ecosystems.

Established in January 1991, the study is among the earliest and longest-running efforts to examine how rising temperatures influence plant and soil systems in alpine environments.Scientists initially expected that warmer conditions would extend the growing season and increase vegetation density.

Instead, the experimental plots showed a steady decline in grasses and wildflowers. Over time, these species were replaced by sagebrush, transforming sections of the meadow into landscapes resembling arid scrubland. Researchers also observed significant changes below ground, where fungal communities in the soil shifted in response to sustained warming.

The findings, published in the Proceedings of the National Academy of Sciences, indicate that such ecosystems may not respond to warming in ways previously anticipated. The study concludes that these meadows could largely disappear in the coming decades if global temperatures rise by 2°C above preindustrial levels.

The transformation observed in Colorado is part of a broader ecological process increasingly documented in cold regions worldwide, commonly referred to as “shrubification.” This process involves the gradual replacement of grasses and low-lying vegetation with woody shrubs and, in some cases, trees.

According to Sarah Dalrymple, a conservation ecologist at Liverpool John Moores University who studies similar changes in Iceland, warming temperatures are reducing environmental constraints that historically limited plant growth in cold climates.

She said that as conditions become less severe, plant communities shift from grasslands or heath ecosystems toward shrub-dominated landscapes, with potential progression to forested environments.

Dalrymple noted that grasses and alpine plants are adapted to short growing seasons and harsh climatic conditions. As these constraints ease, shrubs and trees, which require longer periods to establish leaf and stem structures, gain a competitive advantage.

This transition represents a fundamental reorganization of ecosystems that have remained relatively stable for thousands of years.

While the expansion of shrubs and trees can provide benefits such as increased shelter for wildlife, livestock and human activity, researchers say the broader implications are more complex. Dalrymple said that the spread of woody vegetation in cold regions is associated with processes that can accelerate climate change, particularly through the thawing of permafrost.

Permafrost contains large quantities of stored carbon, and its melting can release greenhouse gases into the atmosphere. Dalrymple said that afforestation in these environments can intensify this process, contributing to increased carbon emissions. She emphasized that the rapid pace of ecological change is a key concern, particularly given its potential effects on the global carbon cycle.

Researchers stress that shrubification itself is not inherently negative but is indicative of broader systemic changes driven by rising global temperatures. Dalrymple said the primary issue lies in the inability to control carbon emissions, with vegetation shifts representing a downstream consequence rather than a direct cause.

Scientists involved in the Colorado study and related research warn that the rate of change appears to be faster than earlier projections suggested. The assumption that ecosystems would respond gradually to warming is being challenged by evidence from long-term observations, which show rapid and sometimes irreversible transitions.

Dalrymple said these changes are not confined to a single region but are occurring across multiple high-altitude and high-latitude environments. This suggests that similar transformations could take place in mountain systems globally, affecting biodiversity, water cycles and land use patterns.

Despite these trends, parts of the Colorado meadows continue to display the dense, insect-rich floral landscapes that have drawn visitors for decades. Souza, who has been visiting the research area since 2012, described the environment as unusually vibrant, noting the intensity and abundance of flowers during peak bloom periods.

She said the visual richness of the landscape remains striking but acknowledged concerns about its long-term stability under continued warming.

The contrast between present-day conditions and projected future changes underscores the uncertainty facing ecosystems that have historically depended on stable climatic conditions.
