Seasonal water shortages

In the more arid savanna regions of the Amazon basin and Brazilian Cerrado, the problem of nutrient depleted soils is compounded by seasonal water shortages. As discussed by M. Haridasan in chapter 5, savanna vegetation is thus of greatly reduced... 

However, changes in the seasonality of snowmelt coupled with shifts in precipitation patterns may result in water shortages in the summer and autumn, especially in downstream regions. For the River Rhine, for instance, some scenarios show a decrease in total discharge of more than 50% at the German-Dutch border for the low-flow period in the autumn [78]. Moreover, the declining impact of snow and ice melt will increase the year-to-year variability of discharge in the summer and autumn.
