The island of Bali has several traditional Aga villages that survive under the pressures of an intense tourist industry and agricultural changes. In order to understand possible impacts on traditional ethnobotanical knowledge (TEK) in Bali, we interviewed local people living in 13 traditional villages regarding the number of known plants and their uses. We analyzed socioeconomic factors influencing change of such knowledge at both individual (informant) and community (village) level. We identified a total of 149 food and nutraceutical plants being used in the study area. Neither gender, occupation, income, nor level of formal education had a significant effect on TEK. However, informant’s age and village status were found to play an important role in the retention of TEK at an individual level. At the village level, the use of Internet/smart phones was an important predictor of cultural erosion
