Abstract: Data from three stations Agra, Dehradun and Dehli, were analyzed for evaluation of changes in rainfall and temperature regimes in the upper and middle parts of the Ganga basin in northern India. Long-term data on monsoon rainfall, the number of rainy days during the monsoon season, and the annual maximum temperature at these stations were included in the analysis. Nonparametric methods were employed to identify trends, if any, in these data. The analysis shows that the total monsoon rainfall and the number of rainy days during the monsoon season are on the decline, whereas the annual maximum temperature is on the rise. These changes are observed to have begun around the second half of the 1960's. The results point towards a possible change in the climatic regime of the Ganga basin that has far-reaching implications for the Indian economy. Copyright Kluwer Academic Publishers 1997
