Over-pumping of aquifers is a worldwide problem, mainly caused by
agricultural water use. Among its consequences are the falling dry
of streams and wetlands, soil subsidence, die-off of phreatophytic
vegetation, saline water intrusion, increased pumping cost and loss
of storage needed for drought relief. Stopping or reversing the
trend requires management interventions. The North China Plain
serves as an example. A management system is set up for a typical
county. It contains three components: monitoring, decision support
based on modelling, and implementation in the field. Besides all
monitoring data, the decision support module contains an irrigation
calculator, a box model, and a distributed groundwater model to
project the outcomes of different water allocation scenarios. In
view of grain security, a solution combines an adaptation of the
cropping system with imports of surface water from the South. The
Open Access book does not only describe the problem and the path to
its solution. It also gives access to nine manuals concerning
methods used. They include computer programs and the game Save the
Water. The Chinese experience should be of considerable interest to
other regions in the world which suffer from over-pumping of
aquifers.
