The dynamics of adaptive tourism sustainability in Hanjeli Tourism Village, Sukabumi Regency, Indonesia, were investigated to assess how local communities respond to tourism-induced transformations and how such responses influence economic resilience. A qualitative research design employing a case study approach was adopted to compare socioeconomic conditions prior to and following the village’s transition from a primarily agriculture- and mining-based economy to one centered on tourism. Historically reliant on subsistence farming, labor migration, and unregulated gold mining, the village has undergone a significant shift towards the cultivation of Hanjeli (Coix lacryma-jobi) and the implementation of educational tourism. Although initial resistance to tourism development was observed, a gradual adaptation was facilitated through the mobilization of endogenous resources, the implementation of community-based tourism (CBT), and the application of the sustainable livelihood framework (SLF). The involvement of stakeholders in homestay management, agro-tourism services, and local product development was found to significantly enhance economic resilience and reduce dependency on extractive and unsustainable income sources. The findings indicate that when adaptive strategies are rooted in local resource management and reinforced by active community engagement, long-term tourism sustainability becomes attainable. It is further suggested that policy frameworks should prioritize capacity-building programs and the diversification of economic activities to buffer against fluctuations in tourism demand, particularly under the influence of global uncertainties such as climate change and economic downturns.
