Data are finally being compiled on our aquifers. No one knows how much water is down there, but at least it is now possible to measure how much is flowing in and how much we’re pulling out. Eight major aquifers in Asia and Africa have little or no flow in, but are being depleted anyway. Those regions are unsustainable, which means populations in the millions may have to move. Attention is drawn to California, where the drought means little is going in, withdrawals now mean up to 60% of local water is coming from wells, and the ground is sinking at a foot or two a year; but other dense regions are in similar distress even without a drought. More migrations?
