Future scenarios of land use change in the Gran Chaco: how far is zero deforestation?
(Springer, 2022-09-12)
The Gran Chaco (Argentina, Paraguay, Bolivia and Brazil) has turned into a global deforestation hotspot as a consequence of the agricultural expansion. These land use changes can lead to large socio-ecological conflicts. ...
Ecosystem loss assessment following hydroelectric dam flooding: The case of Yacyretá, Argentina
(Elsevier, 2015-10)
The Yacyretá dam is one of the most important hydroelectric projects in La Plata Basin. As a consequence of the filling of the reservoir to its final height of 83m, approximately 1,076km2 of terrestrial and riparian ...
Genetic variability in populations of the terrestrial isopod Armadillidium vulgare living in soils with different land uses
(Elsevier Gmbh, 2018-11)
The Argentine Pampas region is recognized by its high productivity and fertility, which make its soils suitable for agricultural use. However, the intensification of agricultural activities over the last forty years has ...
Multi-Temporal analysis of remotely sensed information using wavelets
(Scientific Research Publishing, 2012)
Land cover changes (LCC) are an important component of Global Change. LCC can be described not only by its occur-rence, but also by the land cover replacement, causal agent and change duration or recuperation. Nowadays, ...
Crop intensification, land use, and on-farm energy-use efficiency during the worldwide spread of the green revolution
(National Academy of Sciences, 2018-03)
We analyzed crop production, physical inputs, and land use at the country level to assess technological changes behind the threefold increase in global crop production from 1961 to 2014. We translated machinery, fuel, and ...
Roads and land tenure mediate the effects of precipitation on forest cover change in the Argentine Dry Chaco
(Pergamon, 2022-01)
Dry forests are among the most threatened ecosystems globally, due to agricultural expansion driven by the increasing demand for food, fibers, and energy in developed and emerging countries. Among these, the forests of the ...
Land use change and commodity frontiers: Perceptions, values, and conflicts over the appropriation of nature
(University of California Press, 2020-12)
Argentina is experiencing an expansion of soya and maize cultivation that is pushing the agricultural frontier over areas formerly occupied by native Chaco forest. Subsistance farmers use this dry forest to raise goats and ...
Land-use changes in the periurban interface: Hydrologic consequences on a flatland-watershed scale
(Elsevier Science, 2020-06)
The aim of this work was to analyze the hydrologic effects on surface runoff and infiltration of changes in land use and land coverage. The periurban-flatland watershed of El Pescado Creek (Argentina) was the study site ...
Social Perspectives on Deforestation, Land Use Change, and Economic Development in an Expanding Agricultural Frontier in Northern Argentina
(Elsevier Science, 2019-11)
The idea that agricultural production and environmental conservation are almost incompatible has divided nature protectionists, advocates for indigenous peoples, and agricultural producers. Discourses seem to cluster along ...
Temporally-Consistent Annual Land Cover from Landsat Time Series in the Southern Cone of South America
(MDPI, 2022-08)
The impact of land cover change across the planet continues to necessitate accurate methods to detect and monitor evolving processes from satellite imagery. In this context, regional and global land cover mapping over time ...
