Ground Water Resources
Management
Water scarcity is the most important natural constraint
to Jordan’s economic development. Rapid increases in
population and industrial development have placed
unprecedented demands on water resources. Total demand
is approaching one billion cubic meters per year, which
approximates the limit of Jordan’s renewable and
economically developable water resources. For several
years, renewable groundwater resources have been
withdrawn at an unsustainable rate. Current water
demands are not being met satisfactorily throughout the
country (both spatially and temporally), and the costs
of developing new water resources are rising rapidly.
Groundwater is the major water resource in Jordan; it is
the only water resource in some areas within the
country. 12 groundwater basins have been identified in
Jordan. Most basins are comprised of several aquifer
systems. About 80% of Jordan’s known groundwater
reserves are contained in three main aquifer systems:
(1) Amman/Wadi El Sir (B2/A7); (2) Basalt (Ba); and, (3)
Ram). The long term average of the annual renewable
available groundwater in Jordan is approximately 275 MCM/a
Most renewable groundwater resources presently are
exploited to their maximum capacity. In some cases
abstraction exceeds the safe yield of the aquifer. In
recent years, over pumping has exceeded 200 MCM/a.
Today, aquifers in 7 groundwater basins are being over
pumped with abstractions ranging from 135 to 225% of the
safe yields. In 4 basins abstractions equal the safe
yield. Overexploitation of aquifers has and will
contribute significantly to the degradation of
groundwater quality and endangers the sustainability of
these resources for future use.
The agricultural development in Jordan started in the
early 1970s and nowadays around 70% of the abstracted
groundwater is being used for irrigation. The increased
agricultural land use brought about a deterioration of
groundwater qualities in many areas through the
application of fertilizers and pesticides. This is
noticed chiefly by the increasing salinities caused by
irrigation return flows, such as in the Azraq region,
the Dhuleil-Hallabat region and the north-eastern
desert, but also by continuous increases in the nitrate
contents in groundwater. In order to protect and
conserve Jordan's groundwater resources, measures of
groundwater quality conservation need to be implemented.
This could be achieved by protecting the sources for
domestic water supply by establishing groundwater
protection areas. Also watershed management and land
development must take into consideration the
requirements for groundwater protection.
