El propósito de este artículo es el estudio del proceso de gravamen sobre el latifundio durante las décadas de 1940 y 1950 como parte de un conjunto de políticas agrarias en torno a la propiedad y tenencia de la tierra (arrendamientos y colonización) que contemplan los niveles de producción, de…
La deforestación en Sudamérica afecta principalmente a tres ecosistemas: El Cerrado en Brasil, la selva de Chiquitanos en Bolivia y el Gran Chaco en Bolivia, Paraguay y Argentina, siendo en estos dos últimos países en donde ocurren las mayores transformaciones del paisaje para la producción de…
El presente trabajo es un ejercicio empírico que describe y analiza la dinámica de las tierras en la colonia agrícola de Pigüé, Provincia de Buenos Aires, durante fines del siglo XIX y comienzos de XX. Para ello se utilizaron, como fuente principal, mapas rurales (1884, 1913 y 1929) pobre los…
Land-use land-cover (LULC) changes are one of the major threats to biodiversity worldwide, since their principal consequences are the loss, fragmentation or degradation of the habitat available for most species. Therefore, in order to provide guidelines for environmental management at the…
In recent years, there has been an increasing interest in the study of climate change effects on plant phenology. However, the effects of other more localized components of global change such as land degradation have been almost completely ignored. In this paper we evaluate the phenological…
This work addresses increasing concerns about water management for rural productive activities in the vast dry regions of Latin America by assessing renewable energy technologies (RETs) that could be suitable for localized needs. Forecasted trends in climate change and variability make this…
Fire management requires an understanding of the spatial characteristics of fire ignition patterns and how anthropogenic and natural factors influence ignition patterns across space. In this study we take advantage of a recent fire ignition database (855 points) to conduct a comprehensive…
Studies to assess the relationship between agriculture production and biodiversity conservation usually focus on one gradient ranging from a natural reference land cover type (typically forest) to an intensive productive land use. However, many semi-arid ecoregions such as the dry Chaco are…
PURPOSE: Land use in dry lands can result in a final stage where land is completely depleted or entirely degraded causing the desertification phenomenon. The first part (part 1) of this series of two articles proposed a methodology to include desertification in life cycle assessment (LCA). A set…
The distribution of mosquito populations is spatially heterogeneous and influenced by factors acting at a wide range of scales. The aim of this study was to assess the role of environmental heterogeneity at the landscape level in shaping the composition of immature mosquito communities…
Around 11.5∗10⁶m³ of rock detached from the eastern slope of the Santa Cruz valley (San Juan province, Argentina) in the first fortnight of January 2005. The rockslide–debris avalanche blocked the course, resulting in the development of a lake with maximum length of around 3.5km. The increase in…
En todas las regiones áridas y semiáridas del mundo se considera a “las tunas”, como proveedoras de usos múltiples con notables condiciones para zonas marginales. Los tunales, fueron siempre de interés para Santiago del Estero, Argentina, desde su fundación, iniciándose luego una serie…
