Rural tourism is considered a viable strategy for achieving sustainable rural economic development and poverty reduction, offering significant economic, social, cultural, and ecological benefits. However, as an external force, rural tourism disrupts the livelihood capital and strategies of farmers, significantly influencing their sustainable livelihoods. This paper uses the sustainable livelihood analysis framework from a micro perspective to assess rural tourism's impact on farmers' livelihoods, particularly in Jiwodu Village, Guangxi, China. By categorizing farmers based on the proportion of rural tourism income in their total household income—Tourism-related, Tourism-dominated, and Tourism-exclusive livelihoods—the study constructs a farmer livelihood capital scale, employs a participatory assessment method, and compares changes in the five major livelihood capitals before and after rural tourism development, exploring farmers' perceptions of its impact.
