Today the Sem Terra are recognized by the Brazilian government as interlocutors of the claims of rural workers: present in almost all states of the country, they are about a half million members and, through their struggles, on the edge of legality, 350 thousand families have conquered the land and other 150 thousand are fighting for recognition of their temporary settlements (assentamentos). Maria de Jesus and the other women we meet, living in the Brazilian state of Cearà, are convinced that with the action they can change the world. Maria de Jesus reviews his adventurous life, between jobs and great loves born from politics. in Brazil, 1.6% of the landowners possess 46.8% of the arable land, and that 51.4% of these large estates are unproductive. Brazil is among the first places in the rankings of global inequality and the concentration of capital. Despite holds 6 times more arable land of China, Brazil can not feed many of its inhabitants. And here, in the semi-arid area or “Sertao” of Ceará (among the poorest areas of the country), the sustainable use of resources and biodiversity conservation have become the watchwords of the Sem Terra.
