Irrigation

This paper describes a PIM initiative undertaken by the Government of  Andhra Pradesh. The need for PIM in Andhra Pradesh, was felt because farmers, especially those in the lower reaches of the command area of the project, suffer from inadequate and unreliable supplies.

The Phad system of irrigation which has been going on for centuries, is found in the northwestern parts of Maharashtra in the three river basins of Panjhra, Mosam, Kan and Aram. Weirs were constructed on these rivers to divert water for agriculture use. These weirs are locally called Bandhara. Each independent Phad system comprises of a diversion weir, a canal on the bank and distributor channels for irrigation.

Since time immemorial water has been a common property and in many Indian communities there is deep reverence for flowing water. Using the flow of water for community benefit  is considered an act of great merit and  its misuse and contamination, a sin. In temples, tanks were constructed for rituals and also as a way to earn money for the temple.

This publication by the Central Water Commission presents data on Major and Medium Irrigation and Multipurpose projects, Minor Irrigation projects, Command Area Development scheme as available in the Finance A

Tanks are rainwater harvesting techniques which capture water during monsoons for later use. Mention of tanks in colonial texts is made and the authors infer from ancient texts like Tamil Purananuru on the importance of tanks and the locations for their construction, as well detailing their geographical spread.

There is mention of the importance of water in daily life in various prayers in the Rigveda. The author states that the earliest evidence of water conservation goes back to 3000 B. C. when Gabarbands were built in Baluchisthan. The Harappans built tanks and wells and were pioneers of well-digging technology.

The author gives a brief history of tank irrigation in South India. The number of irrigation tanks in India were 208,000, of which 120,000 were in the three Southern states of Andhra Pradesh, Karnataka and Tamil Nadu. These tanks irrigated 1.8 million hectares. The author uses graphs to point out to the decline in tank irrigation.

A civil society consultation was held on “Regenerating natural resources and rural livelihoods in rainfed areas of India” by WASSAN at Hyderabad in December 2010 to discuss priorities for the twelfth five year plan. The Planning Commission, Government of India has been steering the process of development in India by conceptualizing five year plans and had sought inputs from civil society organizations, activists groups, networks of CBOs / NGOs, donors and others for preparing an approach paper for twelfth plan.

The objective of the consultation workshop was to contribute to the process of defining broad contours of twelfth plan with a focus on rural livelihoods the thrust area being policy framework, funding support, institutional arrangements etc., by -

• Consolidating the lessons from good practices in promoting and protecting rural livelihoods in the country, that could be integrated in twelfth five year plan.
• Systematically articulating issues and concerns (bottlenecks) in promoting and protecting rural livelihoods, which could be addressed in the twelfth five year plan.

Ministry of Water Resources (MoWR) provides financial assistance to promote research work in the field of Water Resources Engineering. The assistance is provided by way of grants to academicians/experts in the Universities, IITs, recognised R&D laboratories, Water Resources / Irrigation departments of the Central and State Governments and NGOs. Research proposals of applied nature as well as basic research are considered for MoWR support.

Considering wide range of topics covered by Water Resources Engineers, five committees called Indian National Committees (INCs) have been constituted to co-ordinate the R&D programme. The five INCs are:

INC for Hydraulics Research (INCH)

• Management of Floods
• Hydraulic Structures (including masonry and concrete structures)
