COMBATING WATER CRISIS Challenges & Opportunities Mushtaq Ahmad Gill (T.I.) Executive Director South Asian Conservation Agriculture Network (SACAN)
Low agricultural productivity Increasing population pressure Dwindling land for agriculture Shrinking water resources Limiting/diminishing energy resources Shortage of electricity High cost of diesel High water losses in irrigation system Over exploitation of groundwater PAKISTAN’S AGRICULTURE CHALLENGES
WATER CRISIS IN PAKISTAN (AFTER INDUS WATER TREATY- 1961) Deprivation from water of eastern rivers (20 MAF) Water logging, salinity & sodicity Increase in domestic and industrial requirement Deterioration of groundwater quality Increase in demand of irrigation water Persistent drought
Cereal Requirement Status of Selected Countries by 2025 Deficit/Surplus (MMT) ISSUES
ISSUES (Cont’d) ,200 m CANAL DIVERSION (MAF)
PAKISTAN WATER BUDGET - INDUS BASIN IRRIGATION SYSTEM SHRINKING WATER RESOURCES

Productivity Enhancement in Canal and Non-Canal Command areas (marginal land and water conditions)and desert and semi desert areas through Water Saving Technologies and Practices in order to: foster sustainable food security improve livelihoods reduce poverty environment friendly agriculture OPTION

CHALLENGES AND ISSUES Scarcity of irrigation water High cost of development of irrigation schemes Colossal loss of land due water and wind erosion Undulated topography Prevailing poverty Limited infrastructural facilities Frequent weather/climate changes Heavy farm machinery requirements for cultivation Scattered and small holdings Shortage of skilled and unskilled labour Poor access to inputs
DEVELOPMENT OPTIONS Supply of canal water to the desert/semi-desert areas Establishment of mini dams, check dams, dugwells, lift irrigation schemes etc. Construction and renovation of water storage ponds, underground tanks (Kunds), and Tobas by use of cost effective lining/layering materials (e.g. HDPE/plastic sheets etc.) Adoption of Resource Conservation Technology Use of alternative energy sources (solar and wind) powered pumps for conveyance of water from water storage tanks to fields by use of drip/sprinkler and Flexible Gated Pipes Management of groundwater by treated, cyclic and conjunctive use
Ongoing Development Strategies Construction of Large and Small Dams Construction of New Canal Systems –Greater Thal Canal (GTC) - Punjab –Katchi Canal - Balochistan –Rainee Canal - Sindh –Chasma Right Bank Canal (CRBC) - KPK

WAY FORWARD National Water Policy Provincial Water Visions in Accordance with Post IWT Scenario 1961 – Indus Water Apportionment Accord 1991 (CBM’s) Creation of Think tank ( Planning Commission, HEC, Universities, PEC, PSAE) for Water Resources Development and Management
Desert areas may be developed following the models of Alien (UAE), Sanai (Israel/Egypt), Ghobi (China), Rajasthan (India), and Dasht-e- Kavir (Iran) Feasibility study and preparation of development projects for Conservation Agriculture may be carried-out through involvement of private sector (consultants/companies e.g. PSAE,SACAN etc.) A body on the pattern of Thal Development Authority and Arid Land Development Authority, India may be constituted under the Supervision of Prime Minister at federal and CMs at provincial levels. A project for development of 50,000 acres at Head, Tail and Middle of Thal desert, with main focus on GTC area, may be launched Outsource the project implementation to the private sector following the example of Rajistan Development in India with full support from public sector WAY FORWARD (Cont’d)
