The importance of precise future projections of precipitation trends cannot be over-looked in water resourcesmanagement and socio-economic development of any country. In this study, the bias-corrected output (future projectionsof precipitation) of two Regional Climate Models (RCMs), CCAM and RCA4 is plotted against the observed historicprecipitation data (1970-2000) for Mangla basin to evaluate the annual precipitation trends in near and far future i.e.(2011-2040, 2041-2070 and 2071-2100) under both RCP 4.5 and 8.5. Comparison of the results indicate that therewould be more precipitation (increasing trend) in mid period (2041-2070), and significant decrease is noticed for the lastperiod (2071-2100) of the ongoing century. Consequently, due to the changing trends in climate variables and land usepractices the basin may face extreme events in future. To cope with such alarming situation proper pro-active strategiesand planning is essential.
