This French‑language volume offers a comprehensive overview of the Société d'aménagement foncier et d'établissement rural (SAFER), the public agency responsible for managing and developing rural land in France. Drawing on legal frameworks, policy analysis, and case studies, the work explains how SAFER intervenes in land transactions, protects agricultural territories, and promotes sustainable rural development. Readers gain insight into the mechanisms of land tenure, the balance between private ownership and public interest, and the legislative tools that guide land use planning. The text serves as a practical reference for professionals in land management, policymakers, and anyone interested in the intersection of law, agriculture, and rural economics.
