The climate change is an important global issue impacting the water resources worldwide. The environmental changeability would lead to rapid melting of glaciers and increased evaporation rates leading to the shortage of available water resources. The climate change would also increase the frequency and intensity of extreme climatic events such as droughts, heat waves and cold epochs etc., and hydrological response such as floods. The human activities significantly impact the water resources availability. The increasing concentrations of CO2 and other greenhouse gases, for example methane (CH4), nitrous oxide (N2O) and Ozone (O3) significantly contribute to the climate change and influence the water resources. This systematic review is focused on the impacts of climate change and human activities on the water resources. These changes will profoundly impact the development of the different regions of the world economically and socially. The climate change impacts the vegetation with changes in distribution, growing seasons and productions. The physiological and hydrological processes are also being affected by climate change and because of human being.
