Study of rainfall and temperature is one of the main topics in taking the decision and planning the development and management of civilization. The nonparametric Mann-Kendall test for trend analysis of climatic variables has been applied to investigate the regular occurrences of drought during the last few decades. The sign test indicates that there is a falling trend in the seasonal rainfall and number of rainy days in a few blocks. However, in our study we have taken the data of rainfall and temperature data from 1990-2014 where used to identify seasonally, variability, trends in Chitrakoot. From analysis of annual seasonal and monthly rainfalls data series it can be concluded that rainfall characteristics of the area is changing even though results of trend analysis of annual rainfall data show no statistically significant trend for period of record considered. The results of the Mann-Kendall trend analyses showed that monthly rainfall and temperature an overall upward and downward trend over the Chitrakoot region. The annual rainfall showed that non-significant decreasing trend at the 95% and 99% confidence levels in the rainfall and temperature over the Chitrakoot region. The results of the Sen’s slope trend analyses also showed that monthly rainfall and temperature an overall upward and downward trend and the annual rainfall and temperature showed that non-significant decreasing trend at the 95% and 99% confidence levels over the Chitrakoot region. All the results signify no significant detectable effect of global warming on the annual, monthly and seasonal rainfall trend in Chitrakoot Region. Air pollution and deforestations from urbanization process are some of the factors that affecting the climate change. As the environmental impact from urbanization process maybe quite minimal on this area, this could lead to the least change in rainfall trend.
