Boat-shaped houses of the indigenous Li people on Hainan Island, China: plant resources and ecological adaptations.
Article in Journal of ethnobiology and ethnomedicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe traditional boat-shaped houses of the Li people on Hainan Island, China, reflect centuries of ecological adaptation to the tropical rainforest. These vernacular dwellings are now threatened by rural depopulation and rapid modernization. We explore the ecological function, material use, and cultural value of the boat-shaped houses of the Li people and support their nomination as a site of UNESCO World Natural and Cultural Heritage.
methodsWe combined ethnobotanical surveys, environmental measurements, and literature analysis to evaluate plant-based construction, house-environment interactions, and traditional knowledge.
resultsThe study identified four types of traditional boat-shaped houses of the Li people on Hainan Island, constructed using 26 plant species across 13 families. Environmental monitoring showed that in natural conditions, boat-shaped houses had lower indoor air temperatures (by 1.3 °C in Chubao Village), reduced relatively humidity (by 7.3% in Baicha Village), and significantly lower wet bulb globe temperatures (by 9.6 °C in Baicha Village), compared to modern brick houses. Boat-shaped houses thus provided a more thermally comfortable environment than modern brick houses, particularly during the dry season. The results emphasize the green, low-carbon construction cycle of boat-shaped houses and highlight the urgent need to conserve this ecologically sustainable traditional knowledge system.
conclusionsLi boat-shaped houses demonstrate a low-carbon, climate-adaptive building system rooted in indigenous knowledge. Their preservation offers critical insights for sustainable design and biocultural conservation in tropical regions.
