Irrigation is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation water can come from groundwater (extracted from springs or by using wells), from surface water (withdrawn from rivers, lakes or reservoirs) or from non-conventional sources like treated wastewater, desalinated water, drainage water, etc.
Irrigation
- Irrigation involves the artificial application of water to soil or agricultural fields, serving as a replacement or supplement to rainwater. Primarily utilized in arid regions and periods of insufficient rainfall, the goal of irrigation systems is to support the growth of agricultural crops and plants. This is achieved by ensuring the minimum required water amount, suppressing weed growth in grain fields, and preventing soil consolidation, among other benefits.
Types of Irrigation Projects
- In India, irrigation schemes are categorized by the former Planning Commission into three types: minor, medium, and major irrigation projects.
- Major Irrigation Projects: Culturable command areas exceeding 10,000 hectares. Involves the construction of large dams to bring water to fields.
- Medium Irrigation Projects: Culturable command areas ranging from 2,000 to 10,000 hectares. Incorporates canal systems as integral components.
- Minor Irrigation Projects: Culturable command areas up to 2,000 hectares. Includes structures such as wells, ponds, drip irrigation, and sprinkler systems.
- The cultural command area is the basis for the design of a watercourse and basis for the design of an Irrigation project. It is the proportion of the gross command area which is culturable and cultivable.
Modern Methods of Irrigation in India
Some modern methods of irrigation in India are described below
- Flow Irrigation (Surface Irrigation) The water of a reservoir or tank usually remains at a higher level and when a channel is connected to it. water automatically flows down the channel which serves the purpose of a canal for irrigating the land. In this case, the water level remains higher than the fields.
- Lift Irrigation Where the farmlands lie at a higher level and the canals or tanks lie at a lower level, it becomes necessary to lift the water by pump etc.. to irrigate land. Water is lifted from wells and tanks, by a crude country method (by tend) and from tubewells by pumps for irrigation.
- Drip Irrigation In this technique, water is delivered at or near the root zone of plants drop by drop. This method can be the most water-efficient method of irrigation if managed properly since evaporation and runoff are minimized. It is also called trickle Irrigation.
- Sprinkler Irrigation Nowadays, Sprinkler ort Irrigation is becoming very much popular as more land can be irrigated with less water in this method. It is affordable and easy to set up.
Sources of Irrigation
| Source | Percentage |
| Canal | 24% |
| Tubewells | 46% |
| Tanks | 3% |
| Other wells | 16% |
| Others | 11% |
Irrigation by Irrigation
- This is the most convenient method of irrigation, danals is situated in Punjab, Haryana, Uttar to About half of the total area under irrigation by Pradesh and Andhra Pradesh.
- Various perennial canals crisscross the diverse regions of the country, boasting renowned ones like the Upper Bari Doab and Sirhind canals in Punjab, as well as the West Yamuna and Chakra canals in Haryana.
- The Chakra Canal, being the largest in the country, plays a vital role in irrigating the states of Punjab and Haryana.
- Rajasthan takes pride in the Rajasthan Canal, also known as the Indira Gandhi Canal, which holds the distinction of being the longest canal in Asia.
- This canal efficiently irrigates the North-Western part of Rajasthan. Other significant canals include the Sharada canal, Betwa canal, and the Upper Ganga and Lower Ganga canals in Uttar Pradesh.
- Additionally, many canals have been strategically dug along the rivers Krishna, Godavari, and Tungabhadra in Andhra Pradesh.
Irrigation by Wells and Tubewells
- Wells and tubewells contribute significantly to irrigation efforts. In regions with soft and porous soil, such as the Western part of Uttar Pradesh, some areas in Bihar, and the black cotton soil region of the Deccan, wells are essential for drawing water from lower depths.
- Coastal strips in Tamil Nadu and Andhra Pradesh, along with certain parts of Rajasthan, Haryana, and Gujarat, also rely on wells for irrigation.
- Power-driven pumps, whether electric or diesel, have gained popularity across various regions, aiding in lifting water from greater depths in wells and tube wells. In some areas, traditional methods involving cattle or camels powering Persian wheels are still employed.
- Modern advancements, such as windmills, have emerged as cost-effective solutions for lifting water from wells, albeit with limitations on the irrigable area.
Irrigation through Tanks
- Tank irrigation stands out as the most viable and widely practiced method across the peninsula, where small tanks are commonly built by individuals or groups of farmers, forming embankments across seasonal streams. The hard and stony soil, along with undulated terrain, hinders the digging of canals or wells in these areas.
- Some significant tanks are created by raising high embankments along one side of the valley hills, while large reservoirs like Nizam Sagar, Usman Sagar, Hossain Sagar, and Krishnaraj Sagar dot the landscape of peninsular India.
Pond Irrigation
- Both natural and artificial ponds serve irrigation purposes in India, with pond irrigation gaining popularity in peninsular regions, including Tamil Nadu, Karnataka, Telangana, and Andhra Pradesh. The cost involved in pond irrigation is minimal, and many ponds also facilitate fish production. However, most ponds dry up in the summer, limiting year-round irrigation.
Multi-purpose Projects in India

National Water Grid Mission
- The National Water Grid proposes an extensive engineering approach to manage India’s water resources by interlinking rivers through a network of reservoirs and canals.
- Dr. KL Rao proposed the idea in 1972 to interlink perennial and non-perennial rivers, aiming to address floods in perennial rivers and droughts in peninsular states. However, the Central Water Commission rejected the proposal due to funding and technical concerns.
- In 1980, the Government of India initiated a perspective plan for water resource development and established the National Water Development Agency (NWDA) in July 1982.
- Although revived in 2003, the interlinking process has been sluggish, with proposed benefits including hydro-power generation, irrigation, navigation, employment, drought and flood resolution, and ecological restoration facing opposition.
National River Conservation Plans
- The Ganga Action Plan (GAP) Phase-I began in June 1985 as a centrally funded scheme to prevent Ganga pollution and enhance water quality.
- GAP Phase-II and the National River Conservation Plan (NRCP) extended river cleaning efforts to major rivers nationwide.
National Water Mission
- Launched under the National Action Plan on Climate Change (NAPCC), the National Water Mission addresses global warming threats.
- Goals include creating a comprehensive water database, assessing climate change impacts on water resources, promoting citizen and state actions for water conservation, focusing on vulnerable areas, increasing water use efficiency by 20%, and encouraging integrated water resources management at the basin level.
Pradhan Mantri Krishi Sinchayee Yojana (PMKSY)
- Launched in July 2015, PMKSY aims to provide protective irrigation to all agricultural farms, promoting rural prosperity.
- Components include Accelerated Irrigation Benefit Programme (AIBP), Integrated Watershed Management Programme (IWMP), Har Khet ko Pani Scheme, and Per Drop More Crop Scheme.
- Implemented by the Ministries of Agriculture, Water Resources, and Rural Development, it covers all states and Union Territories, including the North-Eastern States.
