Guarani Kaiowa Indian Dilcia Lopes and her children watch a truck pass from their makeshift camp squeezed between highway BR 463 and their ancestral land called Tekoha Apika'y, where they have been since 2009 when they last failed to take back the land from farmers, near Dourados, Mato Grosso do Sul state, August 8, 2013. The Guarani tribe is immersed in a bloody conflict with farmers over possession of their ancestral land that has characteristics of a territorial war, in spite of Brazil's indigenous policy being considered one of the most progressive in the world. The conflict highlights the risks being run by an agricultural superpower whose leftist government is trying to sort out centuries of ethnic disputes over ownership of the land from which much of the nation's wealth sprouts.
