A try-out of the technique to grow paddy without puddling at village Chehlan of Ludhiana has resulted in higher yield in comparison to puddled fields, while saving water in the process. The crop was ready for harvest days before expected time, saving irrigation water otherwise to be used for another fourteen days. This trial was funded and supervised by ATMA, a central govt. scheme under the Union Ministry of Agriculture.
Puddling is a traditional method of flooding paddy fields with running water, whereas in non-puddling technique, ‘ridges and furrows’ are formed in soil to let water store in spaces and let it stay, thus reducing irrigation frequency.
“Not paddy but puddling is the enemy of waters of Punjab. It is wastage of water to puddle fields as most of it just evaporates. We have saved 45-50 per cent of water in non-puddled fields. Our yield has been almost 30 per cent more from fields where crop was not puddled. Also, non-puddled crop matured very early, saving at least ten days of irrigation water,” says Rupinder Singh Chahal (43) who along with his brothers Jasvir Singh (48) and Kulwinder Singh (52) experimented with ‘non-puddling’ technique on four acres this year.

Accepting that reservoirs operation and flood management in India lack scientific supports, Madhavan Nair Rajeevan, Secretary, Ministry of Earth Sciences, in an interview has revealed that dams and water reservoirs need flood management systems that use scientific methods to understand when the time is right to open the gates.
“As per my understanding, no big reservoir has a decision support system. So we don’t know when to open them, how to open them… I am not attributing the Kerala floods to an individual. There is a common perception that in India most of the flood management systems are not supported by science… I am very sure we don’t have the decision support system and we need it.” https://indianexpress.com/article/india/not-just-kerala-no-scientific-dam-water-management-across-india-madhavan-nair-rajeevan-secy-earth-sciences-5322003/ (24 Aug. 2018)
In another interview he says that while Kerala records among the highest amounts of rainfall in the country, the State did not have a flood warning system in place. He added that while there were several sophisticated tools to anticipate extreme weather events, India still lacked a mechanism to effectively deploy them. https://www.thehindu.com/sci-tech/energy-and-environment/reservoirs-not-managed-using-a-scientific-decision-support-system-m-rajeevan/article24785253.ece (26 Aug. 2018)
Further in a detailed interview, he pitches for ‘decision support systems’ at dams, acknowledges the challenge of climate change, warn against repercussions of ‘fast-warming’ Indian Ocean. https://indianexpress.com/article/india/kerala-floods-m-rajeevan-ministry-of-earth-sciences-met-department-5324840/ (26 Aug. 2018)

Patoda: How a village in drought hit State turned water self-reliant At a time when almost every village in drought-hit Marathwada is facing acute water scarcity tiny Patoda, on the fringes of water-starved Aurangabad city, is offering valuable lesson in water management conservation and harvesting. Though it is surrounded by arid villages but Patoda’s residents regard water as more precious than money. They follow strict rules about usage and strictly carry the water audits. Water meters are installed in every households and entire village recycles each drop of waste water it generates. Today no rain water flows out of the village. Percolation has recharged the aquifers and the water table has risen. So effective is its water conservation model that Patoda has now become a model for the rest of Marathwada and has won 22 state & national awards. But it did not happened over nights. In fact it is a result of over 10 years joint efforts done by villagers.
