This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities.
To foster this strategy at a national level the World Bank recommends the following. Do: regularize land tenure; expand land registration; privatize public housing stock; establish property taxation. Don't: engage in mass evictions; institute costly titling systems; nationalize land; discourage land transactions.
