Rural movements have made diverse demands related to unequal land distribution, displacement at the hands of development projects and dams, environmental and indigenous concerns, neoliberal agricultural restructuring, and insufficient means of livelihood. These movements have benefited considerably from transnational support from conservationists and INGOs. The Movement of Rural Landless Workers (MST) is perhaps the largest contemporary Latin American social movement. As indigenous populations are primarily rural, indigenous movements account for a large portion of rural social movements, including the Zapatista rebellion in Mexico, the Confederation of Indigenous Nationalities of Ecuador (CONAIE), indigenous organizations in the Amazon region of Ecuador and Bolivia, pan-Mayan communities in Guatemala, and mobilization by the indigenous groups of Yanomami peoples in the Amazon, Kuna peoples in Panama, and Altiplano Aymara and Quechua peoples in Bolivia. Other significant types of social movements include labor struggles and strikes, such as recovered factories in Argentina, as well as gender-based movements such as the Mothers of the Plaza de Mayo in Argentina and protests against maquila production, which is largely a women's issue because of how it draws on women for cheap labor.
