climatological budget for Ituverava (SP) for future global change scenario

Abstract

The objective of this work was to evaluate the water budget (BHC) for Ituverava - SP, for three different conditions: acutal BHC, BHC with simulate data of climatic changes, in that was adopted the sceneries A2 - the more pessimist, and B2 - a little more optimist and -10% of precipitation during the winter and +5% of precipitation during the summer, based on the fourth report of IPCC (2007). For this situations, observed that the climate will be hotter and the drought will be longer. And although the prognostics are of an increase in the precipitation total during the summer, the increase of the temperature will increase of the evapotranspirations demands, and the precipitations index won´t be sufficient, increasing the water deficit. Like this, measures should be adopted for a planning of the use and agricultural occupation of the lands, as well as of the sustainable management of water.
