Irrigation

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)

The audit was conducted as a follow up audit of the earlier report on AIBP (No 15 of 2004) to assess whether the performance of AIBP had improved, and also whether the key issues highlighted in the earlier report had been appropriately addressed.

 It is an attempt to understand the effect of rainfall, physiography, lithology, slope and aspect, land use practices, vegetation, altitude, soil type and anthropogenic interference (e.g., road construction and settlement etc.) and other characteristics in the spring recharge zone on the water yield and water quality of the selected springs in the mid-altitudinal belt (lesser Himalaya) in western Himalaya (Uttaranchal).

It was the kick-off event of an ambitious project to find solutions to the groundwater crisis in Gujarat, funded by the PepsiCo Foundation. More details of the project will follow this overview post.

The scarcity value of natural resources has risen due to rising pressure of human population and demands made by modern economics progress. As such managing these resources has become very important.
