ADB funded Issue Paper on
Trends and transitions in Asian irrigation: What are the prospects for the future?
Aditi Mukherji (IWMI)
Presented at the 5th World Water Forum, Istanbul
March 2009
The Issue Paper: Structure
• Why irrigation? Introduction
• Trends and their drivers
• Irrigation scenarios for Asia
• Rise of atomistic irrigation in Asia
• Reform or morph: Unlocking value
• Future challenges and options
Rising irrigation, falling food prices & poverty
But is irrigation expansion like1960s & 1970s possible, or even
desirable?
Population will increase,Climate change is
imminentDo we have enough
water?
Major pathways to meet future food demand in Asia
• Invest in rainfed agriculture• Invest in irrigation
Improve productivity of existing systems (How?)Expand irrigation (Where and of what type?)
• Promote trade from water rich highly productive areas
• Reform irrigation and unlock value
Rise of the atomistic irrigation in South Asia..Net irrigated area under surface irrigation (000’ha)

This calls for entirely different
paradigm of water management
Whither PIM*/IMT*?
Contours of irrigation is fast
changing
*PIM: Participatory Irrigation Management *IMT: Irrigation Management Transfer
Socio-technical Preconditions that support Surface Irrigation
1. Nature of the state1.1 Local authority structures :1.2 State interest in irrigation: 1.3 Ease of Forced Labor:
2. Nature of Agrarian society2.1 Irrigated cropping pattern2.2 Ease of exit from farming2.3 Agrarian institutions
3. Demographics3.1 Population pressure on farm land
4.State of irrigation technology4.1 Availability and Affordability of water lifting and transport
Future of surface irrigation?

PIM/IMT will be difficult to sustain becauseSurface irrigation as a technology of water
mobilization andApplication is being crowded out by
Atomistic irrigation.Strategy? Reinvent surface systems to support
Atomistic irrigation

Best bet for farmer-participatoryIrrigation management. Larger farms,
better levy crop prices and‘right’ capitalization will
Promote PIM.

Adapting yesterday’s systems to tomorrow’s needs: What can be done?
Stage of agricultural development Desired irrigation & drainage strategy
Focus outside agricultureDeveloped economies (e.g. Malaysia)
Seek private investments for system upgradationPrice water at realistic levelsImprove water productivityGo for technological fixes
Export oriented agricultureIntermediate/transition economies
Invest in smaller schemes dedicated to high value cropsInvest in water savingsEnsure financial viability, even if not full cost recovery
Dependent on agricultureDeveloping economies
Concentrate on cereal production & livelihood goalsBuilt new infrastructure if feasible or modernize existing onesProvide government and external financing of irrigation schemes
