SOURCES OF WATER

1. Water Resources situation in Pakistan by murtazazulfiqar (17)

2. SOURCES OF WATER There are two types of major resources of water in Pakistan, natural and artificial. Natural resources include rainfall, rivers, glaciers, ponds, lakes, streams, karez and wells etc. Artificial resources consist of the surface water from rainfall and rivers, which is in excess of the requirements for irrigation and other uses, is stored in dams and reservoirs. The water from these dams and reservoirs is not only used for irrigation and supplying water for daily consumption, but also used for hydroelectric power generation.

3. Rainfall There are two major sources of rainfall in Pakistan i.e. the Monsoons and the Western Disturbances. There is about 70 percent of the annual Monsoon rainfall from July to September. Pakistan has both arid and semi-arid zones. The entire Indus plain receives an average seasonal rainfall of 212mm and 53mm in the Kharif and Rabi seasons respectively. The rainfall varies as we move from the north and northeast to the south of the country. It is only the canal command areas in the NWFP and the northern-most canal commands of the Punjab Province that receive some appreciable amount of rainfall during the summer as wall as in the winter season.

4. Glaciers • There are more glaciers in Pakistan than any other land except North and South Poles. The • glacier area of Pakistan is about 13,680 sq km and on the average is 3 percent of mountainous region • of upper Indus Basin and accounts for most of the river turnoff in summer. Pakistan has greatest mass • and collection of glassiers on the earth. In Karakoram Range, the total length of glaciers is 160 km. • About 37 percent of the Karakoram area is under its glacier, Himalayas has17 percent and European • Alps has 22 percent.

5. Rivers and Dams • Pakistan has been blessed with a number of rivers which are tributaries to the Indus. The five • main rivers which join Indus from eastern side are Jhelum, Chenab, Ravi, Beas and Sutlej, beside three • minor rivers are the Haro, Soan and Siran. There are number of small rivers which join the River Indus • 4 • from the west side, in which biggest river is Kabul and others are Kunar, Punj, Kora. The Gomal • Kurram, Tai, Kohat Tank and several other small streams join the Indus River from the right side.

7. SOURCES OF WATER • Indus Basin River The Indus river basin constitutes of the mountain basins Indus plain, Karachi plains and desert areas of Sindh. Its source of water is snowing, glacier melting and rainfalls.

8. Closed basin Kharan desert It consists of areas of mountain basins of Quetta. Its main sources of water are rainfall and nominal snow.

9. Makran coastal basin Makran coastal basin constitutes of streams of Malir, Hub, Porali, Hingol, and Kech. Its main source of water is rainfall.

10. Groundwater resources Estimated groundwater resources Source: National Water Policy, Vol. II, January 2002.

11. Water reservoirs Pakistan is having three basic reservoirs, namely mangla dam reservoir, Terbela dam reservoir and Chashma barrage reservoir. More small reservoirs like Warsak, Khanpur and Kinjhar lake Are also included as small storage.

12. Utilization Of Water • Irrigation Out of 240.22 maf, 172.21 maf water is utilized for irrigation purposes.

13. Drinking Most of the rural and urban water is supplied from ground water through tube wells and hand pumps. Net consumption is normally about 2% of the total water available.

14. Industry Water is also utilized in Industries basically for cooling purposes and also in manufacturing processes. This utility is less than 1%.

15. Shortage of water As we all know that now a days our country is facing severe shortage of water. There are two main reasons, one natural due to prolong drought---which is beyond the control of a man, and the other due to the gross negligence in the development and miss-management of water resources.

16. Impact on economy / society • Less water means less agricultural yields and to fulfill the food requirements of the nation, we will be dependent on other countries. • Due to less production of main crops, which are wheat, cotton, sugar cane and rice, the Industries related to them will suffer adversely

17. Less agricultural outputs will compel people to head towards urban areas for jobs, which will increase the unemployment further. • The distribution of water is controlled from the center by irsa (Indus river system authority) as per 1991 agreement between the provinces. Now the shortage of water will cause disputes between the provinces, which may cause harm to the national integrity.

18. Water Issue between Pakistan & India • Concern is growing in Pakistan that India is controlling the water flow of rivers that flow from India into Pakistan.

19. Pakistan has raised objections to Indian water projects, but a World Bank-appointed neutral expert rejected most of the Pakistani objections. • Pakistani commentators, think that India is controlling the river waters to strangulate Pakistani agriculture, which could affect Pakistani exports and increase its dependency on food imports.

20. Conclusion The problems faced by the water sector in the country are many, acute and serious. Therefore, building of more reservoirs and an effective management strategy are the needs of time. Also implementation of the recommendations will enable the country to meet the challenges, and achieve the objectives of integrated, efficient, environmentally and financially sustainable development and management of limited water resources. At the same time it will enable us to utilize every drop of our water for our bright future.
