Evidence of the dependence of groundwater resources on extreme Rainfall in East Africa

The paper "Evidence of the dependence of groundwater resources on extreme Rainfall in EastAfrica" by Richard Taylor et al. from 2012 reviews the occurrence of groundwater recharge caused by extreme rainfall events.
These rainfall events have conflicting impacts on people in sub-tropical East Africa. On one hand they are a blessing for groundwater recharge which can only occur if a certain threshold is overcome (amount of rainfall exceed vapour-loss). Groundwater is often the only water source in dry seasons and therefore a necessity of live to those people. With rising population, the groundwater abstraction nowadays rose up to 9 times more than at the beginning of the last century. Therefore, a demand for large scale recharge is given.
On the other hand, these extreme rainfall events have socio-economic consequences - destroying crops, cattle and homes of many people. 
This will become an even more serious issue if those rainfall events occur more frequent in the future due to climate change. If people loose parts of their livelihood to gain others this cannot really be seen as a "sustainable resource". Actions will need to be taken to find a solution to keep the losses as small as possible while receiving the blessings of new freshwater.
