Chapter 9-12

Out of the total geographical area of 130 lakhs hectares in the State, the net area sown is about 60 lakhs hectares, of which about 30 lakhs hectares (50%) gets irrigation facilities from surface water through canals (9.50 lakh hectares), tanks (9 lakh hectares) and wells, tube wells etc. (11.50 lakh hectares). The National Commission on Agriculture assessed the ultimate irrigation potential of Tamil Nadu through Major and Medium Irrigation sources as 15 lakhs hectares in 1976. At the commencement of the First Five Year Plan, there were 23 Major and Medium Irrigation Projects benefiting 11 lakhs hectares. In the Ninth Plan period up to 2001-2002, the area under irrigation through Major and Medium Irrigation Projects had increased to 29.72 lakhs hectares. During 2002-2003 an additional irrigation potential of 4,924 hectares is likely to be created. It is envisaged that during 2003-2004 the additional irrigation potential of 9,804 hectares could be created.

The State is now constrained to find additional water resources through 'trans-basin' diversion of water from the neighbouring States, namely, Kerala, Karnataka and Andhra Pradesh which are blessed with rich water resources which involves 'inter-state' agreements and major policy changes at National level. In this respect, Government of India has formed the National Water Development Agency to look into the urgent need for diversion of surplus water available in the adjoining basins of neighbouring States to augment water resources.

A new World Bank Project namely 'Tamil Nadu Water Resources Consolidation Project' (TNWRCP) was launched during the year, 1995-96 with an approved estimate of Rs.807.49 crores under Major and Medium Irrigation head of development and is in progress. The World Bank has extended the project upto 31.03.2004.

The Cauvery Delta System is nearly 2,000 years old. This system can serve efficiently only if the structural components are modernized. The Government of Tamil Nadu first prepared a master plan for modernization of the Cauvery System including Flood Control and Drainage Rehabilitation in 1,970 for seeking International Financial Assistance. But the project could not be taken up as an Externally Aided Project for want of clearance (Inter State angle) from the Ministry of Water Resources, Government of India. However, the modernization work was taken up in piecemeal to meet the urgent needs of irrigation, flood control and drainage with the State funds. But these efforts were inadequate for the requirement of the Delta.

Therefore, the modernization of the Cauvery Delta is proposed for taking up in three phases. A project report for Phase I, at an estimated cost of Rs. 460 crores, has been sent to the Government of India for forwarding it to World Bank. This project has the following components:

Modernisation & rehabilitation of ten rivers in the delta benefiting 70,000 hectares

A sum of Rs.32.19 lakhs is anticipated expenditure for 2002-03. A sum of Rs.23.95 lakhs is proposed for modernization of Thanjavur channel for 2003-2004 to complete the balance works.

The growth of Ipomea in the irrigation sources is creating major problems in water management and flood control. Therefore silt and Ipomea are being removed by using heavy machinery hired from the Agricultural Engineering Department and other private agencies.

Government has accorded sanction for the year 2002-2003 for an amount of Rs. 20 crores for restoration of channel system. The anticipated expenditure for 2002-2003 is Rs. 22 crores. An amount of Rs.35 crores is proposed for 2003-2004.

Agricultural Engineering Department implements the Command Area Development Programme in 12 command areas as a centrally sponsored and equally shared programme between the State and Government of India. So far, the programme has been completed in Lower Bhavani project, Cumbum Valley project, Periyar-Vaigai project, Sathanur Reservoir project and Amaravathy Reservoir project. The remaining projects viz., Parambikulam Aliyar project, Kothaiyar-Chittar Pattinamkal project and Thambirabarani River Basin projects have to be completed as per the schedule approved by Govrnment of India. Government of India have recently approved three new schemes namely Krishnagiri Reservoir project, Thoppaiyar project and Palar- Poranthalar project under Command Area Development Programme. The Command area Development Programme is implemented below the sluice outlets of the commands.

Command Area Development Programme is implemented basically to ensure improved irrigated agriculture as a central theme and the activities relate to irrigation facilities and its efficient utilisation through the following three major components:

Reclamation of waterlogged areas, saline and alkaline will also be taken up by Agricultural Engineering Department under this programme.

The following infrastructural works are taken up as part of On Farm Development (OFD) works.

Out of the total cultivable command area of 10.97 lakh ha. an area of 8.74 lakh ha. has been covered with On Farm Development in 12 command areas of Tamil Nadu.

Rotational Water Supply or Warabandi is a system of equitable water distribution by turns, according to a predetermined schedule specifying the day, time and duration of water supply to each farmer in proportion to his holding size in an outlet command. The Rotational Water Supply schedule is prepared after executing the On Farm Development works by Agricultural Engineering Department and handed over to the farmers for implementation. Till date an area of 7.04 lakhs ha. has been covered under Rotational Water Supply in Tamil Nadu. Without completion of Rotational Water Supply, Command Area Development Programme will be ineffective and incomplete. Bearing this in mind, it was proposed to give a thrust to Rotational Water Supply in the recent past and accordingly programme intensification is being continued under Rotational Water Supply during 2003-04 also.

Participation of farmers play a major role in the execution of Command Area Development works and ensuring equitable distribution of irrigation water to each individual field at the right place with right quantity at the right time as per water availability and requirements of crops. The participatory approach is now being intensified and enlarged to achieve the transfer of responsibility of operation and maintenance to farmers' council for effective Participatory Irrigation Management (PIM). To achieve this, a 3-tier system is now adopted.

Out of 549 Farmers' Councils registered, an amount of Rs. 1,146.53 lakhs has been released as management subsidy to 401 numbers of registered Farmers' Councils to maintain the infrastructure created under the Command Area Development Programme.

Programme for 2003-04 - It is programmed to cover 46,000 ha. under On Farm Development works and 77,500 ha. under Rotational Water Supply works.

An amount of Rs.1,384.42 lakhs is proposed for the year 2003-04 for implementation of Command Area Development Programme works, as indicated below:
