In this synthesis report, the issue of tenure security is addressed and assessed in several countries where government, civil society, the private sector and development cooperation initiatives have been implemented for decades. The selected case studies from fifteen (Bangladesh, Bolivie, Brésil, Chili, Chine, Ethiopie, Ghana, Guatemala, Indonésie, Kenya, Nigéria, Ouganda, Philippines, Thaïlande, Zambie) countries ensure not only a geographic balance but they also represent countries with different socio-economic and land-related histories and that have followed different pathways. The studies’ key findings underline the still precarious state of tenure security in many countries.
