1. 'My land, your social transformation': Conflicts within the landless people movement (MST), Rio de Janeiro, Brazil

Author:
Caldeira, R.

Subject:
land reform; Brazil
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 ...

Castanea; Fagus; Quercus; correlation; pollen; rain; relative humidity; spring; temperature; wind; Spain
Abstract:
... The concentration of airborne Fagaceae pollen in Salamanca and the correlations with some meteorological parameters have been examined. Castanea and Quercus pollen grains were collected from 1998 to 2004 using a Burkard spore trap. No pollen grains of Fagus were found. The main pollen season took place in April and May for Quercus and in June and July for Castanea. Yearly variations on these dates ...

Abstract:
... This paper examines the usefulness of the new social movements (NSMs) paradigm in the changing context of East European post-communist societies and their agricultural systems and rural communities. Starting with statements formulated in Western sociology in the context of Western democratic societies about NSMs as a protest against modernity, the paper analyses the role of such movements in the s ...

Abstract:
... Deep chiseling in heavy drained soils can help increase infiltration and hence reduce erosion, potentially enhancing growth by reducing excess water in the root zone and reducing nutrient losses through the reduction of runoff to surface waters. The goals of this study were to apply DRAINMOD-K s -STMAX, a modified form of the water management model, DRAINMOD 1) to predict the effects of deep chise ...

Abstract:
... Microorganisms are increasingly exploited as a source of new pharmaceuticals. Soil fungi are particularly promising to this regard since their biocenotic competitiveness is often based on the production of antibiotics and other inhibitory substances. About 15 Penicillium strains possessing some extent of antifungal ability were evaluated as a possible source of antitumor products based on the anti ...
