Resumen:
In the 1950s, and with greater emphasis since 1970, has been detected in large part of Argentina
and especially in the vast Chaco plain a "positive climate jump". This has had a
major impact on natural and man-made ecosystems. The changes associated with the new
demands of international markets for food, enabled the launching of new agricultural activities,
especially soybean crops, which advanced displacing other crops and primarily to
natural forest. The aim of this paper is to analyze the changes in land use under the observed
climate jump in the Dry Chaco of Argentina in the last decades. Using data from the
official network of meteorological stations show the long-term variations in precipitation
and temperature in the Dry Chaco region of Argentina, that covers part of the provinces
of Salta, Formosa, Chaco, Tucuman and Santiago del Estero, in northern Argentina. We
are also considering changes in land use with data coming from the national agricultural
census. The results show that the climate jump in the Dry Chaco is associated with an important
advance of the agriculture, including oilseeds and grains, which together increased
by almost 442,000 hectares the area under cultivation between 1988 and 2002. In return,
the deforested area was almost 910,000 hectares.
