The study showed that vegetation responds to the flooding with a boost in productivity.

Therefore, reducing freshwater pumping should be followed by other measures, such as analysing the aquifers situation before building reservoirs upstream, as this will account for a serious minimisation of its natural recharge and, possibly, for salinisation if the return flow is not guaranteed.
