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 frames the MST collective action and legitimates its raison d'être as a social movement.

Este artículo pretende poner en discusión el tema del crecimiento económico, la demanda energética que este requiere, y los impactos territoriales que provocan las infraestructuras necesarias para suplir esta demanda. Esto desde la óptica del caso chileno, que por sus características energéticas la mayoría de estas se localizan en entornos rurales, sin embargo es en los territorios urbanos donde esta es mayormente consumida.

This paper compares and contrasts patterns of land tenure, property boundaries, and dispute resolution regarding property using examples from two diverse social and economic regions: Bolivia and Norway. The goal of the paper is essentially a comparative one. By placing the examples of Bolivia and Norway side by side, the authors hope to shed light on common strategies while recognizing the diversity to be found in the ways that people relate to land. It is hoped that readers will be able to compare the material here with examples from other regions.

Groundwater vulnerability assessment is an important task in water resources and land management. The most sophisticated among the vulnerability assessment techniques is the GIS-based DRASTIC model. However, despite its popularity, it is marred with excessive subjectivity glitches; little research has been conducted to address the shortcomings associated with this method. This study investigates various issues regarding the application of the GIS-based DRASTIC model through a critical review of relevant literatures.

Approximately 80% of the world’s agricultural landpresents moderate levels of erosion. In Chile, the risks related to soil erosion are greater in thepre Andean mountain areas or coastal dry-lands. However, there are also indications of low levelsof erosion in the Central Valley which, given the importance of this region for the country’sagricultural sector, should be taken seriously to avoid a worsening of the situation. This articleexamines the association of natural, social, human and fi nancial capital variables with the adoptionof soil conservation practices in Linares, Chile.

Patterns of land-use and land-cover change are usually grouped into one of two categories defined by the dominant trend: (1) deforestation resulting from expanding agriculture and (2) forest expansion, usually related to the abandonment of marginal lands. At regional scale, however, both processes can occur simultaneously even in the absence of net change. Given the focus on net change, such redistribution of agricultural and natural and seminatural lands has been generally overlooked.
