International work session on water statistics

and the remaining 50 MCM will be used to intensify agricultural production in the Jordan Valley.
Therefore, Jordan is consider among the poorest countries in the world in terms of water resources
1- Surface water supply
*Source: M.O.W.I-Water Authority
The total quantity of ground water is 520 MCM. The agriculture sector use about 54% of ground water. The municipal use about 40% of ground water, and the remain (6%) used for industrial activity.
Source exceeding 300 millimeters

Table 3 to another, in some basin the over pumping of ground water exceed 3 times of the safe yield, on the other hand the abstraction of water from other basins less than the safe yield.
Some details information by using sample survey was acquired to another, in some basin the over pumping of ground water exceed 3 times of the safe yield, on the other hand the abstraction of water from other basins less than the safe yield.

( ISIC 4 Digit). This data indicate the quantity of water use for each activity by supply.

Rubber and Plastic Products by Water Source, 2002 (M3)
Sources of data water use by economic activity
The 1999 economic enterprises census.
2 – stratification
All enterprises stratified by total revenue into 3 classes, it classified by paid capital, total employee, and it classified by activity 4 digit at the region level.
3 – water use by economic activity sample design
All enterprises classified as big enterprises were surveyed by complete coverage
All enterprises with small number surveyed by complete coverage.
The enterprises remained were divided into middle and small size. After that in each stratum and in each size of enterprises the sampling units were selected.
4-Sample allocation water use by economic activity
The Nyman allocation was applied
The systematic method was applied after ordering all sampling units in each stratum ascending by total revenue, to provide implicit stratification to increase the efficiency of the design.
1- Availability of data
- there are many gaps in the administrative records.
no disaggregating between both public and privet sectors.
- difficult to access to the available data.
2- The quality of data
-the data doesn’t comparable among different sources of data
3- The classification of the available data water use by economic activity
- the ISIC and SNA classifications didn’t apply in the data base.
4- the cost of collecting data by survey method is very high.
5- huge requirements for any survey.
6-This work need skills in both statistics and water science which is not available.
