RESUMO

It is a known fact that the process of nature transformation became faster from the second half of the eighteenth century, with the industrial revolution, marked by the use of steam machinery. The process of urbanization triggered by industrialization caused a negative impact to the environment and climate changes. This work aims to relate changes in climatic behavior rainfall, with the growth of urban spot (area) of the city of Taubaté. Through statistical analysis of behavior in the time-scale yearly and monthly, we compared the rate of rainfall in the past observational data (period from 1950 to 1999), provided by the Department of Water and Power (DAEE) with A2 and B1 sceneries of Intergovernmental Panel for Climate Change (IPCC) and concluded that the volume of precipitation was higher for the spring and summer quarters for both sceneries. We used data from future simulation (period from 2000 to 2099) and concluded that the intense rainfall will be higher for the A2 scenery. Based on the pluviometric index data and the Taubaté city urban area growth, we carried out a succinct analysis of Taubaté city development plans evaluating its commitment to the environment and the problems that extreme precipitations could cause.
