Serie Conservación de la Naturaleza (17) (2006): Climatic change in Tucumán (Argentina): Its impacts

Evidence of climatic change (CC) in the province of Tucumán (Argentina) was detected using statistical techniques applied to the analysis of temperature and precipitation data and other derived techniques like hydric balance. Statistical analysis was used in the analysis of climatic
series where the quality of information is known through previous investigation regarding data history and the application of systematic and aleatory errors control among others. These changes consist of an increase of: long term average precipitation, intense rainfall and cloudy associated with decreases in daytime temperature and increases in nighttime temperatures. All these changes are included in the concept of “tropicalización del clima”. Data showed that in the decades of 1950-1970,  substantial changes have happened in the mean parameters and the changes have geographically expanded in the different regions of Argentina for which, we can suppose a climatic change in a bigger scale. In this study we show the qualitative impact that climatic change will be produced on the natural and antropical ecosystems so as to early prevent about them. The knowledge of this information is important for the State or Companies to make decisions, for mitigating them, or to be fully aware about the application of favorable, reasonable policies to diminish the sys tem vulnerability levels.
