Abstract:
... In Brazil the total area of native and cultivated pasture used for livestock is around 180 million hectares, and selenium (Se) is absent from mineral fertilizer formulas. Nutritional supplementation of this element takes place along with provision of mineral salts in the form of sodium selenite. In the present work, the effects of adding selenate and selenite on Se biofortification, antioxidant ac ...

Abstract:
... In this paper, we analyze the political dynamics of the contemporary 'transnational peasant network' through a comparison of two movements: the Brazilian Movimento Dos Trabalhadores Rurais Sem Terra (MST) and the South African Landless People's Movement (LPM). We argue that transnational visions of 'peasants' often obscure relations between or within rural movements. One tangible benefit of the tr ...

Abstract:
... The Brazilian Movimento dos Trabalhadores Rurais Sem-Terra (MST) is one of the best-known and most prominent rural social movements. The unequal distribution of land in Brazil, and the neglect of this problem by successive Brazilian governments contributed greatly to the organisation of rural movements striving for the implementation of land reform in the country. The struggle for land therefore f ...
