Collective land tenure is considered by many activists in Latin America and the Caribbean to be a key factor in protecting indigenous territory, promoting the social production of habitat, and consolidating urban communities. With the exception of the Caño Martin Peña Community Land Trust in San Juan, Puerto Rico, the CLT model has yet to be widely applied in the region, yet there are precursors and modern-day equivalents in the ejidos of Mexico, the communal territories of Ecuador, and in strategies for reclaiming the lands of indigenous peoples in Bolivia, Brazil, and several Caribbean countries. In urban areas, the cooperative ownership of both land and housing and the cooperative management of municipally owned reserves extracted from the market are found in the Cooperatives de Vivienda por Ayuda Matua in Uruguay and in various struggles and initiatives in Argentina, Brazil, and Venezuela.
