India’s Irrigation Challenge: Is PMKSY equal to it?

INDIA’S IRRIGATION CHALLENGE:

IS PMKSY EQUAL TO IT?

HIGHLIGHTS• Three phases in evolution of Indian

irrigation• How do our farmers irrigate today?• What are key constraints to irrigation

expansion?• What can be done to overcome these?• Example of Madhya Pradesh• Example of Gujarat• How should PMKSY be refocussed?

ERA OF ADAPTIVE IRRIGATION-UPTO 1830

• Community was the unit of irrigation management

Rainfall, soil-moisture, floods

Rainfall and Soil moisture

Flow irrigation from tanks, canals, rivers

Lift irrigation from wells and surface sources

% of water consumptively used in agriculture

% Contribution to aggregateFarm output and incomes

ERA OF CANAL CONSTRUCTION-1830-1970

• State emerged as the architect, builder, manager of irrigation

Canal and tankirrigation

Soil moisture management

Flow irrigation from tanks, canals, rivers

Lift irrigation from wells & surface sources

% water consumptively used in agriculture

% Contribution to aggregateFarm output and incomes

ERA OF ATOMISTIC PUMP IRRIGATION:1970-TODATE

Individual farmer as the irrigation manager

Soil moisture management

Flow irrigation

Pump irrigation from wells, tube wells, canals

India inherited the world’s largest canal infrastructure in 1947; today India is the world’s groundwater champion!

After 1990

India’s GroundwaterJuggernaut is stillAccelerating!!!

India today has some 25 million irrigation wells.2/3rd of these were sunk after 1990..

Over 70% of irrigated areas are served by groundwater wells. Yet, India’s

Irrigation investments are focused on canal irrigation, neglecting groundwater.

2006-07

EACH DOT IN THIS MAP REPRESENTS 5000 IRRIGATION WELLS.

IRRIGATION IS LOW, WHERE GROUNDWATER IS NOT DEVELOPED OR MANAGED

India’s Energy Divide, 2006-07 Eastern India has

abundant groundwater but no energy to pump it

In western India, perverse power subsidies have

ruined aquifers .

India’s pockets of serious

groundwater depletion

54% of India’s Groundwater wells are decreasing

Scarce or depleted

groundwater

DOES PMKSY ADDRESS THESE PRIORITIES?

GUJARAT GOVERNMENT SUPPORTED COMMUNITY BASED CHECKDAM MOVEMENT IN SAURASHTRA, KUTCH AND

NORTH GUJARAT WITH REMARKABLE RESULTS

GUJARAT INVESTED RS 1250 CRORE IN FEEDER SEPARATION; BUT IT HELPED IMPROVE POWER QUALITY AND CONTROLLED

GROUNDWATER DEPLETION

GUJARAT’S AGRICULTURE HAS BEEN GROWING @ 9+%THIS GROWTH IS ENERGIZED BY GROUNDWATER IRRIGATION.YET, GUJARAT IS THE ONLY STATE IN WESTERN INDIA WHERE

GROUNDWATER LEVELS ARE IMPROVING..

SEVEN STRATEGIES TO ENSURE“HAR KHET KO PANI”

• Tighter management of canal systems to bring larger areas under command;

• Rationalize farm power subsidies in western states;• Improve the quality of farm power supply;• Accelerate pump electrification in Bihar, Orissa,

Assam• Decentralised Managed Aquifer Recharge programs;• Revitalize 600,000 irrigation tanks in peninsular

India; • Solarize the groundwater economy by promoting

solar energy as a ‘remunerative crop’.

SOLAR PUMPS OFFER A GROUND-BREAKING IRRIGATION OPPORTUNITY THAT PMKSY IGNORES

• Solar pumps can quickly provide affordable energy to farmers of eastern India and kick-start its green revolution.

• In western India, solar pumps with a buyback guarantee for surplus solar power can offer reliable day-time energy for irrigation, stable cash income and incentive for conserving power and water.
