WATER RESOURCE MANAGEMENT OF PAKISTAN IJAZ -UL-HASSAN KASHIF SMALL DAMS ORGANIZATION ISLAMABAD 1 2 3 INDUS RIVER BASIN FROM SPACE 4 WATER RESOURCE MANAGEMENT Water Resources Management is the integrating concept for a number of water sub-sectors hydropower water supply and sanitation irrigation and drainage environment. An integrated water resources perspective ensures that social, economic, environmental and technical dimensions are taken into account in the management and development of water resources. 5 OVERVIEW Pakistan is one of the world’s most arid countries, with an average rainfall of under 240 mm a year. The population and the economy are heavily dependent on an annual influx into the Indus river system (including the Indus, Jhelum, Chenab Ravi, Beas and Sutlej rivers) of about 180 billion cubic meters of water, that emanates from the neighboring countries and is mostly derived from snow-melt in the Himalayas 6 OVERVIEW-2 The balance between population and available water already makes Pakistan one of the most water stressed countries of the world with rapid population growth it will soon enter a condition of absolute water scarcity 7 8 (Cubic Meters Per Capita Per Year) DECLINING PER CAPITA AVAILABILITY OF WATER IN PAKISTAN 9 WATER RESOURCES OF PAKISTAN Rain fall Glacier Ground water 10 RAINFALL Pakistan lies in an arid and semi arid climate zone Sources of rainfall Monsoon Western disturbances Mean Annual rainfall Lower Indus Plain < 100 mm Upper Indus Plain > 750 mm Average seasonal rainfall Kharif = 212 mm Rabi = 53 mm 11 10 YEARS AVERAGE(1990-99) RAINFALL OF SOME MAJOR CITIES 12 GLACIER Catchment area of Indus basin contains some of the largest glacier in the world outside the polar region. Glacier area of upper Indus catchment is abut 2250 Km2 and accounts about 80% of summer runoff in river. Kabul River originates from southern Hindukush and starts rising approximately a month earlier than Indus and fulfill the irrigation requirement of late Rabi and early Kharif crops. Snow melt account for more than 50% of the flow in Jhelum River. 13 SURFACE WATER ACCOUNT MAF Average annual volume of water from rainfall and snow melt From Western Rivers From Eastern Rivers Diversion for irrigation Flow to see System losses 154.00 144.91 9.14 104.73 39.40 9.90 14 DETAIL OF SURFACE WATER AVAILABILITY MAF River Indus Jhelum Chenab Ravi Sutlej Kabul Total Average Average Average annual flow annual flow annual flow (1922-61) (1985-95) (2001-02) 93 62.7 48.0 23 26.6 11.85 26 7 14 26 189 27.5 5.0 3.6 23.4 148.8 12.38 1.47 0.02 18.9 92.62 15 SURFACE WATER SUPPLIES AND CONSUMPTIONS 16 Ground Water Total Groundwater Potential = Groundwater Abstraction = Punjab (81 % abstraction) 80 % Fresh water, 20 % Saline Sind 55 MAF 41.5 MAF (12 % abstraction) 23 % Fresh water & 77 % Saline NWFP (5 % Abstraction) Balochistan (1.2 % Abstraction) 17 GROWTH IN USE OF TUBEWELLS 18 GROWING ROLE OF GROUNWATER IRRIGATION 19 DEVELOPMENT OF IRRIGATION SYSTEM IN PAKISTAN Description Under Colonial Rule (1850 – 1947) Post independence development (1947-60) Indus Water Treaty 1960 Average annual withdrawals (MAF) 67 85 108~105 20 INDUS WATER TREATY 1960 21 INDUS WATERS TREATY, 1960 SALIENT FEATURES All waters of eastern rivers namely Ravi, Beas and Sutlej allocated to India.

N.W.F.P / Baluchistan projects which are under execution are provided their authorized quota of water as existing uses. Need for additional storages on the Indus and other rivers admitted and recognized for planned future agricultural development. Need for minimum escapages to sea below Kotri to check sea intrusion recognized. Further studies desired to establish minimal escapage needs below Kotri. 38 SALIENT FEATURES OF ACCORD 1991 No restrictions on Baluchistan to develop water resources of Indus tributaries flowing through its area. Need for establishing Indus river authority for implementation of the accord recognized and accepted. IRSA to have headquarters at Lahore and to have representation from the four provinces. Sharing procedure laid down in Para 14(b) of the accord Provinces are free to under take new projects within their agreed shares. Within their allocations provinces may modify uses both system wise and period wise. 39 APPORTIONMENT OF WATERS OF THE INDUS RIVER SYSTEM BETWEEN THE PROVINCES-ACCORD 1991 (MAF) PROVINCES KHARIF RABI TOTAL PUNJAB 37.07 18.87 55.94 SINDH* 33.94 14.82 48.76 (a) 3.48 2.30 5.78 CIVIL CANALS (b)** 1.80 1.20 3.00 BALUCHISTAN 2.85 1.02 3.87 77.34 37.01 114.35 1.80 1.20 3.00 N.W.F.P TOTAL CIVIL CANALS (b)** * INCLUDING ALREADY SANCTIONED URBAN AND INDUSTRIAL USES FOR METROPOLITAN KARACHI. ** UNGAUGED CIVIL CANALS ABOVE THE RIM STATIONS.

These ten daily uses would be adjusted pro-rata to correspond to indicated seasonal allocations of the different canal systems and would form the basis for sharing shortages and surpluses on all Pakistan basis. 41 APPORTIONMENT OF THE INDUS WATERS (PROMISE AND PROSPECTS) – AN HISTORIC ACCORD: 21 MARCH 1991 MAIN FEATURES Existing uses of all provinces to be protected. Allocations to different canal systems to be worked out separately on the basis of ten daily uses. These uses to help determine sharing of shortages and surpluses 42 WATER APPORTIONMENT ACCORD 1991 SHARING PROCEDURE Sindh holds that the available river supply should be shared between Punjab and Sindh on the basis of para (2) accord allocations reflected in para 14(a) of the accord. Punjab emphasizes that the relevant clause for sharing of available river supply is para 14 (b) of the accord, which envisages sharing of shortages and surpluses on all Pakistan basis on the basis of average system uses 1978-82. 43 SHARE OF THE PROVINCES AS PER WATER ACCORD 1991 Province Punjab Kharif (MAF) 37.07 Rabi (MAF) 18.87 Total (MAF) 55.94 Sindh 33.94 14.82 48.76 NWFP 05.28 03.50 08.78 Balochistan 02.85 01.02 03.87 Total 77.34 37.01 114.35 44 INDUS RIVER SYSTEM AUTHORITY Comprises Five Members. One from each Province and one from Federal Government. First Chairman Member Balochistan followed by NWFP, Punjab, Sindh and Federal. Term of Office Chairman One Year Member Three Years 45 DECISION MAKING PROCESS IN IRSA Decisions taken by majority votes. In case of equality of votes, chairman exercises casting vote. Aggrieved party to approach Council of Common Interest for redressal. 46 WATER MANAGEMENT PROCEDURE IRSA prepares the Forecast of Water Availability for Kharif and Rabi crops Based on water availability Forecast IRSA determines Provincial shares according to Water Accord Provisions. Punjab prepares Canal Operation / Distribution Programme based on its share in consultation with Punjab Agriculture Department. If Punjab share is short of requirements Rotational Programme of operation of channels is prepared and implemented by the field formations. 47 PRESENT PROJECTS 48 PAKISTAN WATER STRATEGY AND WAPDA’S VISION 2025 The Pakistan Water Strategy and WAPDA’s Vision 2025 have reviewed likely future demands and the implied requirements for storage. If no new storage is built, canal diversions will remain stagnant at about 104 MAF and the shortfall will increase by about 12% over the next decade. The Pakistan Water Strategy calculates that Pakistan needs to raise storage capacity by 18 MAF (6 MAF for replacement of storage lost to siltation and 12 MAF of new storage) by 2025 in order to meet the projected requirements of 134 MAF. 49 RAISING OF MANGLA DAM PROJECT At Mangla Azad Jummu and Location Kashmir and District Jhelum (Punjab) Dam Type Dam Earth and Rockfill Length 11200 Ft.
