I further admit I am not sure exactly what aquifers we are talking about. To generalise the term (as I understand it) is used about two different sets of underground water, both that which is part of an ecology and that which is sealed of (like oil). Use of the former (above the level of regeneration) causes desertification (and according to maps not all of Libya is deserts) while the latter is a one time boost, preferably to be invested wisely.
