Land ownership is an essential pillar of development. In Madagascar, land is a symbol of wealth and security, making land control a major issue. Access to land, crucial to survival and well-being, remains a challenge, particularly in strategic areas such as Diégo-Suarez. This work aims to regulate the use of land, particularly private land, to balance private, public and environmental interests. Interviews with local authorities, notably the Commune Urbaine de Diégo-Suarez and the DIANA region's land use planning office, enabled us to analyze the conditions of access to land. The aim was to draw up an inventory of administrative procedures for the acquisition of private and public State domains, large-scale landholdings (over 250 ha), as well as specific procedures for mining or construction activities.
