Impacts Water

Declines in water runoff have been measured across north and central China, these relate primarily to human development impacts, but in many cases also to climate. China’s Second National Communication to the UNFCCC (2012) states around 30-40% of the reduction in runoff in the Yellow River can be attributed to climate change. Climate change is expected to further reduce river water levels across much of China with the exception of the southeastern region. Contributing factors to the changes ongoing in China’s water resource profile are the retreat of its glaciers and reductions in its snow cover. Around 82% of China’s glaciers are estimated to be in retreat and climate model ensemble projections suggest the mountain ranges feeding China’s major rivers will lose 20-90% of their mass. It is likely that these changes will further increase the variability and unpredictability of China’s water supply.
