Abstract
Climate change is a major global & environmental issue which is quite popular among climate research community nowadays. Climate change in India can be seen in the form of rising temperatures, floods, droughts, changing pattern of rainfall. In the long run, it could affect agriculture, human health, economic growth & development in many ways. Therefore, there is growing need to assess the impact of climate change on the hydrological processes. The present study intends to evaluate the impact of climate change of Tarai and Bhabar agro-climatic zone in Uttarakhand. Data of two meteorological stations viz. Roorkee and Pantnagar have been used in study. The study mainly comprises the trend analysis of observed rainfall, mean maximum temperature & mean minimum temperature and their future downscaled projections at both stations. Trend analysis has been done using Mann-Kendall test and Sen’s slope estimator to find the significance and magnitude of trend respectively. Multiple linear regression technique has been used for downscaling of CanESM2 model outputs corresponding to 4.5 RCP. It has been found that minimum temperature is increasing over Tarai and Bhabar agro-climatic zone in Uttarakhand. A clear picture of trend in rainfall & maximum temperature over study area has not been emerged from present study. Results obtained from the study could be proved useful in minimizing the hazardous impact of climate change over study area. These results present a true picture of changing climate which is quite helpful to get maximum productivity in many sectors viz. agriculture, economy, forestry, mining etc.
