The organization describes the Movement:
The Brazil’s Landless Workers Movement, Movimento dos Trabalhadores Rurais Sem Terra (MST) in Portuguese, is a mass social movement, formed by rural workers and by all those who want to fight for land reform and against injustice and social inequality in rural areas.The MST was born through a process of occupying latifundios (large landed estates) and become a national movement in 1984. Over more than two decades , the movement has led more than 2,500 land occupations, with about 370,000 families - families that today settled on 7.5 million hectares of land that they won as a result of the occupations. Through their organizing, these families continue to push for schools, credit for agricultural production and cooperatives, and access to health care.
Currently, there are approximately 900 encampment holding 150,000 landless families in Brazil. Those camped, as well as those already settled, remain mobilized, ready to exercise their full citizenship, by fighting for the realization of their political, social economic, environmental and cultural rights.
Here are a few links to learn more about the MST:
The MST is also a founding member of Via Campesina which is:
... the international movement [bringing] together millions of peasants, small and medium-size farmers, landless people, women farmers, indigenous people, migrants and agricultural workers from around the world. It defends small-scale sustainable agriculture as a way to promote social justice and dignity. It strongly opposes corporate driven agriculture and transnational companies that are destroying people and nature.
La Via Campesina comprises about 164 local and national organizations in 73 countries from Africa, Asia, Europe and the Americas. Altogether, it represents about 200 million farmers. It is an autonomous, pluralist and multicultural movement, independent from any political, economic or other type of affiliation.
Comprised of 150 organizations from 70 countries and representing 200 million members, Via Campesina is the World's largest social movement. This global movement introduced the concept of food sovereignty:
Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. It puts those who produce, distribute and consume food at the heart of food systems and policies rather than the demands of markets and corporations. It defends the interests and inclusion of the next generation. It offers a strategy to resist and dismantle the current corporate trade and food regime, and directions for food, farming, pastoral and fisheries systems determined by local producers. Food sovereignty prioritises local and national economies and markets and empowers peasant and family farmer-driven agriculture, artisanal fishing, pastoralist-led grazing, and food production, distribution and consumption based on environmental, social and economic sustainability. Food sovereignty promotes transparent trade that guarantees just income to all peoples and the rights of consumers to control their food and nutrition. It ensures that the rights to use and manage our lands, territories, waters, seeds, livestock and biodiversity are in the hands of those of us who produce food. Food sovereignty implies new social relations free of oppression and inequality between men and women, peoples, racial groups, social classes and generations.
