The vulnerability of glaciers and other climate change impacts on water resources are show'n at map 6.1. It is expected that die peak discharge in non-regulated rivers will shift to earlier months of the year, affecting economic sectors dependent on w'ater supply. It is expected that, by 2050, river discharge will possibly be reduced in summer and in early autumn, the period during w'hich demand for w'ater from agriculture is highest. In the longer term, this would have detrimental effects on the water reserves. According to experts, the speed of siltation has turned out to be higher than forecast.
