This document summarizes an issue paper on trends and transitions in Asian irrigation and prospects for the future. It notes that while irrigation expansion lifted millions out of poverty in the 1960s-70s, population growth and climate change pose new challenges. Major pathways to meet future food demand include investing in rainfed agriculture, improving existing irrigation systems, expanding irrigation in some areas, and promoting trade. It discusses the rise of "atomistic" or small-scale groundwater irrigation in South Asia and the implications for participatory irrigation management. Adapting existing surface irrigation systems to support small farms and groundwater use will be important for sustainability.
Trends and transitions in asian irrigation what are the prospects for the future

3. Rising irrigation, falling food prices & poverty But is irrigation expansion like1960s & 1970s possible, or even desirable? Population will increase, Climate change is imminent Do we have enough water?

6. PIM/IMT will be difficult to sustain because Surface irrigation as a technology of water mobilization and Application is being crowded out by Atomistic irrigation. Strategy? Reinvent surface systems to support Atomistic irrigation Source: Shah, Tushaar. 2009. Taming the anarchy: groundwater governance in South Asia Socio-technical Preconditions that support Surface Irrigation 1. Nature of the state 1.1 Local authority structures : 1.2 State interest in irrigation: 1.3 Ease of Forced Labor: 2. Nature of Agrarian society 2.1 Irrigated cropping pattern 2.2 Ease of exit from farming 2.3 Agrarian institutions 3. Demographics 3.1 Population pressure on farm land 4.State of irrigation technology 4.1 Availability and Affordability of water lifting and transport Future of surface irrigation?

Stage of agricultural development Desired irrigation & drainage strategy Focus outside agriculture Developed economies (e.g. Malaysia) Seek private investments for system upgradation Price water at realistic levels Improve water productivity Go for technological fixes Export oriented agriculture Intermediate/transition economies Invest in smaller schemes dedicated to high value crops Invest in water savings Ensure financial viability, even if not full cost recovery Dependent on agriculture Developing economies Concentrate on cereal production & livelihood goals Built new infrastructure if feasible or modernize existing ones Provide government and external financing of irrigation schemes
