1. Ocupações de terra, acampamentos e demandas ao Estado: uma análise em perspectiva comparada
Based on the observation that land occupations with camps currently place an unavoidable demand on the Brazilian state for land expropriation and redistribution, the article analyzes the sociogenesis of this discourse. The authors seek to: examine how the first landless camps emerged; understand how men and women mobilized to occupy land; and identify relati

2. Cedula da Terra Program : a rereading main results of evaluation studies / Programa Cedula da Terra : uma releitura dos principais resultados
In the 90 , when Brazil was retaking its land refonn, it was built a program complementary to the constitutional mode!. By using market mechanisms to make the access to land ownership speedier, the main goal ofthe Cédula da Terra Program (PCT) was to benefit 15.000 low income families leaving in the Brazilian northeast region countryside. Based on its chara

3. LAND-USE DECISION MAKING, UNCERTAINTY AND EFFECTIVENESS OF LAND REFORM IN ACRE, BRAZILIAN AMAZON
From 1970 to 1999, almost 700,000 families were settled through land reform programs in Brazil. However, lot turnover contributed to re-concentration of land and to the limited success of these programs. This dissertation explores land-use decision-making in an aging land reform settlement in the Amazon. It focuses on how farmers respond to limited access to

4. Soil fertility and 137Cs redistribution as related to land use, landscape and texture in a watershed of ParaÃba state / Fertilidade do solo e redistribuiÃÃo de 137Cs em funÃÃo da cobertura vegetal, relevo e classes texturais, em uma microbacia hidrogrÃfica do estado da ParaÃba
Intensive land use and growing deforestation of the natural vegetation in Northeastern Brazil have contributed to the degradation of resources, particularly the decrease of soil fertility. As a result, biodiversity and ecosystem capacity to restore its resources after disturbances have been diminished. The decrease in soil fertility is more substantial in ar

5. O uso da terra para finalidades agricolas no Brasil no periodo recente
This thesis deals with issues related to agricultural redistribution in a space perspective, since the 70 s. For this purpose, it was resorted to quantitative methods in order to obtain standards for the redistribution of agricultural activities in spacial terms, including comparative analyses among states, regions and farm sizes.

7. Interactions between Auxin Transport and the Actin Cytoskeleton in Developmental Polarity of Fucus distichus Embryos in Response to Light and Gravity1
Land plants orient their growth relative to light and gravity through complex mechanisms that require auxin redistribution. Embryos of brown algae use similar environmental stimuli to orient their developmental polarity. These studies of the brown algae Fucus distichus examined whether auxin and auxin transport are also required during polarization in early
