Argentine

El objetivo del trabajo es realizar un análisis sobre la construcción del poder político post-independiente en la campaña de Buenos Aires. Para ello se examinan conjuntamente dos variables significativas: la política de tierras públicas -especialmente las donaciones ejidales y condicionadas- y la distribución de la riqueza.

En el presente trabajo se realiza un análisis comparativo de la dinámica del pastoreo en dos comunidades de la puna o altiplano jujeño, a fin de identificar las diversas estrategias empleadas para reducir los riesgos y la incertidumbre asociada a la actividad pastoril.

El objetivo del trabajo es examinar la revisión oficial de las “donaciones condicionadas” implementadas en el partido de Azul y la respuesta de la sociedad rural durante la segunda mitad del siglo XIX.

Governments in a number of countries are trying to address concerns about land grabbing by closing their borders to foreign investors. Are these restrictions effective?

How have Latin American countries been using Environmental Impact Assessments in order to build more sustainable extractive industries? A focus on Peru provides some interesting lessons.

Liu, X., Burras, C. L., Kravchenko, Y. S., Duran, A., Huffman, T., Morras, H., Studdert, G., Zhang, X., Cruse, R. M. and Yuan, X. 2012. Overview of Mollisols in the world: Distribution, land use and management. Can. J. Soil Sci. 92: 383–402. Mollisols – a.k.a., Black Soils or Prairie Soils – make up about 916 million ha, which is 7% of the world's ice-free land surface.

A methodological protocol of strategic environmental assessment was developed to incorporate the valuation of ecosystem services in land use plans. The protocol was applied in rural land planning at Balcarce, a department representative of the Southeast Pampas Region (Argentina).

Vegetation exerts a strong control on water balance and key hydrological variables like evapotranspiration, water yield or even the flooded area may result severely affected by vegetation changes. Particularly, transitions between tree- and herbaceous-dominated covers, which are taking place at increasing rates in South America, may have the greatest impact on the water balance.

We assessed the extension of natural habitat conversion into croplands and grazing lands in subtropical NW Argentina and its impact on two key ecosystem functional attributes. We quantified changes in remotely sensed surrogates of aboveground net primary production (ANPP) and seasonality of carbon gains.

The sunflower (Helianthus annus L.)-soybean [Glycine max (L.) Merr.] intercrop has emerged as an option that increases land productivity in the southern Pampas of Argentina, compared with sole crops, because of complementary use of resources between species.

Policies play a pivotal role in determining land change. Uruguay has been subject to first a rise and then decline in plantations of exotic trees as a result of internal Uruguayan government policies, and a recent substantial increase in soybean cultivation that may be attributed to Argentinean policies.

Notwithstanding the increasing cattle activity on the South American temperate forests, its impacts on the forests regeneration are yet poorly understood. We investigated the influence of cattle on the regeneration of monkey puzzle tree (Araucaria), an endangered conifer of the temperate forests of Chile and Argentina, on properties of small landowners and of timber companies.
