The historic and ongoing dispossession of land and resources from First Nations and indigenous communities throughout the Americas is both a site of intensive academic and scholarly investigation, and social mobilisation and resistance. Today, the threat posed by extractivist industries to the health and survival of First Nations and the environment have prompted coalitional and solidarity activism at sites such as Standing Rock Indian Reservation in the U.S., and the Unist’ot’en Camp in Northern British Columbia, Canada. These protests embody a resurgence of indigenous claims for sovereignty over their land, and a rejection of the colonial settler property relations and legal forms that are at the root of their dispossession. At the same time, people in Europe and Latin America (as elsewhere) have been confronting an intensification of forms of dispossession in urban sites, particularly in the aftermath of the 2008 financial crisis. The housing crisis in many European and Latin American cities, a result of speculative practices in the realm of real estate, gentrification, and the intensified privatisation of social goods such as water and transport, have led to challenges to both the private ownership model and public enterprise that privileges privatisation and deregulation. The efforts to push back against these different forms of dispossession, from indigenous sovereignty movements in North America to practices of commoning in Latin America and Europe, and the theoretical concepts they give rise to, cohere around a strident critique of private property relations and the desire to re-imagine relations of ownership that offer the possibility of more collective, equitable and just forms of land use, urban space and resources. For the first time, this workshop will bring together leading scholars in the fields of political theory, law, and sociology to consider these two trajectories of scholarship and activism together.
