Customary tenure refers to locally derived systems with norms, rules, institutions, practices and procedures that have evolved over time and use. They govern the use, allocation, access and control over natural resources that are held – not owned – in common by groups of people, such as pasture, forest and water. Customary tenure systems have gained social legitimacy and are negotiated, sustained and changed by local communities. (FAO, NRI and AWARD. 2026. The status of women in agrifood systems in sub-Saharan Africa. Rome. https://doi.org/10.4060/cd9262en)
