Overexploitation of Groundwater Resources and their Environmental and Socio-economic Implications

-the case of Jordan-

This article will illustrate the over-exploited, non-equilibrium state of the groundwater resources of Jordan as an

example on the groundwater situation in most MENA countries.

JORDAN…story of the place

• 4th Water scarcest country globally.

• 148 m3 Annual per capita supply.

• Groundwater deficit is about 315MCM (if all water withdrawn fromsprings is included).

• 62.4% of water consumed is in agriculture, generating 2.8% of total income and employing only 6% of workforce.

Abstract

Jordan like many other countries, especially those of the MENA region is overusing its groundwater resources stocks.

The present impacts on the groundwater itself are manifested in:

•Drop in groundwater levels.•Reduction in spring discharges.•Saltwater intrusions.•Deteriorating water quality.

The resulted socio-economic impacts are :•Human health.•Declining agricultural productivity due to higher water salinity.•Larger investments in the purification of increasingly deteriorating water.•Operational coast of wells increased.

6

Development of the groundwater resources in Jordan

The major development of the groundwater resources in Jordan started during the seventies of the last century.

During the early seventies, the major aquifers in the surroundings of development centers were first tapped.

During the second half of the 70ies, groundwater development extended to other aquifers and areas.

In the eighties, all major groundwater basins were developed for municipal, industrial and irrigation supplies.

Declining water levels

All major aquifers in Jordan witnessed declines in their water levels.

Only in small areas surrounding wastewater effluent discharges and leaky dams, have water levels risen slightly (MAR dams).

As a result of non-equilibrated extractions, already during the eighties vital groundwater basins started giving sings of overexploitation such as steadily dropping water levels and quality degradation. Examples on that are Jafr, Dhuleil and Azraq.

• During the nineties, all groundwater basins in Jordan were suffering of overexploitation expressed in depletion and quality deterioration.

• By now some of the major groundwater basins has become beyond repair andare considered as lost, such as Dhuleil, Jafr and partly Azraq

• Water level dropping rates ranging from 30 to 120cm/yr (WAJ files).

• The saturated thickness of aquifers go up to a maximum of around 150m (WAJ files). Continuing with the present extraction rates, the major aquifers are expected to irreversibly deplete within 10-30 years (Except Disi)

19

Spring discharge

Springs in almost all parts of Jordan were negatively affected. Springs discharges declined or stopped and in some of them salinity increases and quality deterioration were registered.

The Jordanian Justice witnessed, during the 80s and 90s of the last century, filings of many processes of spring water users against well owners who, due to water pumping from wells negatively affected spring discharges or caused, discharges to stop.

Socio-economic impacts

The strong drops in groundwater levels, in most basins, forced well owners in many areas to deepen their wells.

Salinity effect on in the agricultural activities. (Jafr, Dhuleil, Azraq etc)

26

Water Authority resorted to the very limited surface water resources as a source of municipal water such as, King Abdullah Canal water.

The mal-functioning of the treatment of surface water for municipal use led to two catastrophes during the last two decades.

The situation of water resources depletion and deterioration is not restricted to Jordan, but it is also the case in Saudi-Arabia the Gulf States, and North Africa (Lloyd 1998, Margat 1993, WB 1994. Foster 1992, Margat and Saad 1982 Mangat 1992).

37

•Discussion

• Water depletion and pollution management efficiency can be measured by its performance.

• Misuse of water resources, water pollution, over-utilization or not respecting sustainability principles and intergeneration equity indicate unsound water resources management.

• It should never be accepted that the cause of development is used as a reason to sacrifice the water resources whether quantitatively or qualitatively.

• Development should be compatible with the water resources issues,.

38

Any project generating depletion and degradation of water resources without the mechanisms and economic instruments to repair that degradation can be regarded as a misallocation and misuse of water resources.

Any water development plan whether for urban, industrial or agricultural use should include an economic feasibility aiming at objectives beneficial to the society.

39

The history of humans in the area of MENA throughout the last three to four millennia has been determined and shaped largely by this major infrastructural element, water. Agriculture developed when the amount of rain was sufficient to support plant life.

Irrigated agriculture was practiced along water courses such as the Nile,Euphrates, Tigris and Jordan Rivers and springs as well as around oases.

40

• MENA countries development has been concentrated in agriculture, mainly irrigated agriculture.

• Sharp increase in population.

• New challenge to development.

41

The present shortage in water resources and the expected sharpening of demand should give rise to water policies.

The challenge facing us is to develop and introduce the necessary technologies for water and waste water systems.

42

Leakage detection and maintenance is a more economical way to increase the efficiency of water supply (more than 30% in Jordan) Waste water treatment and reuse should become an integral part of water supply.

In the coming decade high-cost projects, environmental hazards and tightened budgets will make large water projects unattractive and difficult to implement (Dead Red Canal).

43

•Competition for the water resources.

•New resources require new thinking and new management procedures.

•MENA countries should develop water strategies with adequate dynamic instruments in it to enable comprehensive planning.

44

•The change to an efficient water economy will not be an easy task.

•Groundwater abstraction should be limited to aquifer safe yields; it should have no adverse effects on the groundwater quality or quantity.

•Future generations rights.
