15 WATER USES IN PAKISTAN Pakistan has an integrated irrigation system According to Indus Waters Treaty, all the flows of the three Eastern Rivers (Ravi, Beas and Sutlej) are allocated to India Replacement works including link canals and storages were constructed to transfer waters of the Western Rivers to the areas of that were previously irrigated by the Eastern Rivers

16 WATER USES IN PAKISTAN Waters of the Kabul River coming to Pakistan are presently being utilized in Khyber Pakhtoonkhwa, Punjab, Sindh and Balochistan Irrigated Area in IBIS - Pakistan = 31 million acres Current Irrigated Area in Kabul Basin - Afghanistan = 0.45 million acres

17 WATER USES IN PAKISTAN DescriptionHistoric Withdrawals As per 1991 Water Accord (MAF) IBIS – Kharif6872 IBIS – Rabi38 Annual – Total106110 Groundwater (Annual) 42 Grand Total148152

18 Inflow = 137 MAF Diversion = 106 MAF

19 Inflow = 93 MAF Diversion = 90 MAF

20 INDUS BASIN INFLOWS 1976-2000150 MAF 1976-2008144 MAF

21 IMPORTANT FINDINGS In Kabul basin outflows from Pakistan are about 8.0 MAF while Inflows are estimated as 17.5 MAF; Pakistan is getting more than double the amount of water which flows from Pakistan to Afghanistan

22 IMPORTANT FINDINGS The current water uses in Afghanistan are 1.8 MAF while the future uses are estimated as 3.6 MAF; the additional water use is estimated as 1.8 MAF

23 IMPORTANT FINDINGS Agriculture in Afghanistan has been heavily dependant on springs, karezes and rehats. At present the groundwater use is minimum as the karezes need maintenance. It is estimated that present groundwater use is 0.2 MAF which would increase to about 0.5 MAF with investments in rehabilitation of irrigation system

24 IMPORTANT FINDINGS Incremental surface water use for future condition is estimated as 1.5 MAF. Afghanistan is presently using less than 10% of water of Kabul River Basin while the future use would be within 20%.

25 IMPORTANT FINDINGS Pakistan is using more than 90% of the water of Kabul River Basin which may reduce to 80% in future. IBIS-Pakistan’s total present water use is estimated as 148 MAF; (106 MAF surface water + 42 MAF GW)

26 IMPORTANT FINDINGS Surface water inflow at rim station is estimated as 144 MAF Pakistan faces water shortages in Rabi season and at the start of Kharif season. Thus, additional diversion by Afghanistan in Kabul basin would negatively affect Pakistan during the Rabi and early Kharif

27 IMPORTANT FINDINGS The magnitude of impact on inflows is 1 – 1.5%

28 IMPORTANT FINDINGS The impact on canal diversions will be less or negligible in the years in which escapages to sea are higher than the required. However, in the years in which escapages to sea are less than the required, the impact will be either on canal diversion or environment

29 IMPORTANT FINDINGS Detailed studies on cropping patterns and resulting demand pattern and system operation (combined Afghanistan+Pakistan) are required for determining the exact magnitude of impact and its time of occurrence

30 IMPORTANT FINDINGS Afghanistan intends to build storages to bring additional area under cultivation. The storage operation (filling and release) can be done in a manner so that harm to Pakistan’s agriculture is minimized e.g. if filling of storage is done in July-September period, the negative impact on Kharif sowing in Pakistan may be obviated

31 IMPORTANT FINDINGS Pakistan can mitigate the impact by building new storages so that extra water flowing to sea is stored and utilized

32 IMPORTANT FINDINGS Improving irrigation system efficiencies may also help Research and use of improved seed varieties and irrigation practices that require less water and are drought resistant

33 How to Take-up the Matter with Afghanistan? In view of the relatively low uses in Afghanistan (current + future) as compared to Pakistan, it would not be possible to ask Afghanistan not to develop its water use in Kabul basin

34 How to Take-up the Matter with Afghanistan? The sharing of water use should be according to the rule of equitable utilization which requires that watercourse nations shall participate in the use, development, and protection of an international watercourse in an equitable and reasonable manner with a view to attaining optimal and sustainable utilization and benefits consistent with adequate protection of the watercourse. [Article 5 of UN Convention on the Non-Navigational uses of International Watercourses;May 21, 1997]

35 How to Take-up the Matter with Afghanistan? Pakistan should point out that additional water use in Afghanistan would negatively affect agriculture in Pakistan, specifically in drought years

36 How to Take-up the Matter with Afghanistan? Pakistan may emphasize that Afghanistan should inform Pakistan on its development plans. The proposal of Pakistan- Afghanistan joint commission for harmonious development of water resources would be a useful starting point

37 How to Take-up the Matter with Afghanistan? Afghanistan should carry out development in an efficient manner (from the water-use point of view) so that harm to Pakistan is minimized.

38 How to Take-up the Matter with Afghanistan? Afghanistan may be asked to submit the master plans and feasibility studies of the projects for review by Pakistan for arriving at agreed figures of water uses with efficient water use methods. In case there are differences, these may be resolved by the experts of the two countries

39 How to Take-up the Matter with Afghanistan? In case of storage projects Afghanistan should agree to build only that magnitude of storage which is consistent with its irrigation and power needs in the Kabul basin

40 How to Take-up the Matter with Afghanistan? The storage filling period should be outside Kharif sowing season in Pakistan ( March to May)

41 How to Take-up the Matter with Afghanistan? Afghanistan should rehabilitate its karezes and rehats to bring these to fully functional level so that surface flow diversions for agriculture are minimised

42 How to Take-up the Matter with Afghanistan? There should be regular monitoring of the facilities in Afghanistan and information of monitoring supplied to Pakistan. Pakistani experts would visit the facilities in Afghanistan for confirmation of the operation of the facilities in the agreed manner

43 How to Take-up the Matter with Afghanistan? Pakistan should highlight that it has also right to develop hydropower and irrigation facilities in the Chitral/Kunar basin in its territory but it will be done in a manner that uses in Afghanistan on the same river (Kunar River) are not adversely affected
