CAMBIAMENTI CLIMATICI E CONSEGUENZE SUL DRENAGGIO E L’IRRIGAZIONE
2008
Giuseppe Taglioli | Riccardo Alessandri
In the last years, many scientists have discussed about climatic changes. In Italy an important decline of precipitation and a general increase of temperatures were registered at the end of the last century. The study of precipitations over a 65 years period in a part of the Province of Ferrara confirmed this trend. The SPI index was calculated with the rainfall data. The results of this study point out that we are going toward a period of drought, especially as regard of stratum water resources. Another important fact is the increase of evapotraspiration in summer periods. Finally, we demonstrate that an increase in rain intensity will lead to a necessary change in the distance between ditches of about 20%. In the future, careful attention must be addressed to irrigation and drainage in order to ensure good agriculture practices.
