The rainfall increase has partly contributed to a significant expansion of agricultural area, particularly in climatically marginal regions of the Pampas. However, it is unclear if current agricultural production systems, which evolved partly in response to enhanced climate conditions, may remain viable if (as entirely possible) climate reverts to a drier epoch. We assess the potential impacts of a plausible decreasing trend in precipitation on the economic sustainability of two contrasting agricultural systems in the Pampas: Pergamino, in the most productive subregion of the Pampas and Pilar, in the northern, semi-arid margin of the region. Also, we explore the scope for adaptation to changing climate. In the case of no adaptation, if precipitations decrease as projected, impacts may be quite different between locations: whereas in Pergamino crop economic returns do not change noticeably, the more marginal Pilar experiences a marked decrease of profits and an increase of production risks. However, potential negative impacts might be mitigated in part if farmers adapt their agronomic management using current available technology or know-how UCAR/NCAR - Library OpenSky Support PO Box 3000 Boulder CO 80307-3000 opensky@ucar.edu http://opensky.ucar.edu/ homepage pointOfContact PDF Text theme Resource Type 2016-01-01T00:00:00Z publication Copyright 2009 Inter-Research.
