Resumen:
This paper correspond to the project “Updating the geographic knowledge for the social economic development of Northwestern Patagonia, Argentina” of La Plata National University, Argentina. An analysis of the northwestern Patagonia was performed because this region has also the water sources of the rivers that sustain the most important productive in irrigated agricultural activities and the hydroelectric power of the region. The water has been the great limiting factor, conditioning the development of the region. For that, the population has been settled near the watercourses to fulfil the needs of potable water and eventually satisfy other requirements, from either the agriculture or the industry. The study area from Northwestern Patagonia includes part of Neuquén, Río Negro and Chubut provinces, where are located very important human activities. Population and Housing Census 1991 and 2001 are studied in the sixteen departments of the study area, with the aim of carrying out a comparative analysis of both temporary cuts in the field of study. Three departments, Confluencia, Bariloche and Futaleufú, present the most important concentration of population. The used meteorological stations correspond to the National Meteorological Service and the hydrological stations to the National Water Resources. The analysis of daily air temperature shows significant changes in maximum temperatures of January in Esquel (42° 54’ S, 71° 09’ W, 785m) and minimum temperatures of July in Neuquén (38° 57’ S, 68° 08´ W, 271m) for the period 1980 - 2006. Mean annual precipitation presents an important interdecadal variability.
