Introduction: This article examines the social, economic and institutional dynamics underlying the persistence of land-related conflicts associated with artisanal diamond mining in the villages of Bobi and Forona, located respectively in the sub-prefectures of Bobi and Diarabana, in the Séguéla Department of the Worodougou Region of Côte d’Ivoire. Particular attention is paid to the tensions arising from the coexistence of customary and statutory law in the governance of mining-related land. Methodology: The study adopts a mixed-methods approach combining documentary research, semi-structured and unstructured interviews, focus group discussions, and a questionnaire survey. The questionnaire was administered to 64 artisanal diamond miners, including 42 in Bobi and 22 in Forona. The analysis draws primarily on the theory of legal pluralism (Griffiths, 1986; Vanderlinden, 1972), complemented by social conflict theory (Marx, 1867; Dahrendorf, 1959) and the theory of access to resources (Ribot and Peluso, 2003). Results: The findings indicate that the respondents are predominantly married men (87.30%), while 67.18% are primarily engaged in mining activities. Access to land is organised through both open-ended arrangements, notably customary grants and theoretically prohibited sales, and time-limited arrangements, such as loans, tenancy agreements and leases involving the payment of rent. The conflicts identified are predominantly intra-family disputes (35.93%), followed by conflicts between indigenous community members (31.25%), boundary disputes (18.18%), and inter-village conflicts (14.06%). Conflict resolution remains overwhelmingly grounded in customary mechanisms (75% of cases), whereas administrative intervention accounts for only 25%.
