Can land, trees, structures, farms, pipes, poles, pumps etc, along a river bank several kilometers downstream collapse if water flow in the river is suddenly reduced or stopped? Yes, reduced/ stopped, not increased? This kind of river bank slump or collapse or failure is not easily understood, but it does happen. Let us see how.

Godavari Basin in Maharashtra: A Profile

The river Godavari is the largest of the peninsular rivers of India. Maharashtra is home for its early flows and Godavari for Maharashtra is no less than Ganga. Referred to as Dakshin Ganga the river holds immense spiritual and cultural significance. Several places at its origin are said to be abode of Rama during the exile. These places are worshipped even today.

One of the unique aspects of this river is that it drains nearly entire East to West length of Maharashtra. And while running ceaselessly towards the Bay of Bengal the river encompasses nearly all the geographically diverse regions of the state. Originating in Western Ghats this river later traverses through the arid and dry region of Marathwada and then emerges in high rainfall region of Vidarbha. While the Upper Godavari sub basin is a part of prosperous sugar cane growing belt of Western Maharashtra; its tributaries like Manjara and Wardha-Wainganga flow through the region where there is still significant potential of local water systems.

DRP News Bulletin 06 March 2017 (Farm Ponds In Maharashtra Causing Groundwater Decline)

SANDRP Blog Farm ponds in Maharashtra Causing Groundwater Decline Farm ponds recognized as a drought proofing measure have received a great push from the central Govt recently. On the flip side however serious concerns are being raised over implementation of the farm ponds and more importantly –their use. Civil society organizations like Watershed Organization Trust and also SANDRP have been pointing out that the use of farm ponds has long drifted from its objective of storing rainwater for protective irrigation. Most of the farm ponds are instead being used as storage tanks for pumped out groundwater exposing this underground resource to losses through evaporation, etc. In the process they are accelerating the rate of groundwater exploitation multi fold.

Lahaul people write to Environment Committee not to clear Reoli Dugli Hydro project

To

The Environment Appraisal Committee

River Valley Projects

Ministry of Environment and Forests

New Delhi

Subject: Submission related to Chenab River and Lahaul Valley  in context of EC for 430 MW Reoli Dugli project

Dear Chairperson,

We have read reports that the expert appraisal committee (EAC) on river valley and hydel projects of the Ministry of Environment has decided “not to take any cognizance of representations” received by its members since such representations are ‘anti-development’. The article appearing in Indian Express on January 14, 2017 stated, “In its December 30 meeting, the committee concluded that once a project proposal reaches the EAC for appraisal, it has crossed the stage of public consultation and “the EAC should not go back in time, and should not reopen it, by entertaining unsubstantiated representations received from the people”.

Maharashtra Farm Ponds: accelerating groundwater exploitation, rather than harvesting rain?

Farm ponds dotting the agricultural fields immediately grab your attention as you enter Hiwargaon Pawasa – a small village of about 1500 population in Sangamner Taluka of Ahmadnagar District. The village is located just off NH-50, the national highway connecting Pune and Nashik. Farm ponds start to appear as soon as you turn east from NH-50 (which broadly runs North South) to head towards Hiwargaon. Nearly every farm, small or big, has a plastic lined farm pond. Hiwargaon Pawasa village alone has some 300 odd farm ponds.

I am here to see how these small scale irrigation facilities now set to be implemented on massive scale through the country are performing on ground. Continue reading “Maharashtra Farm Ponds: accelerating groundwater exploitation, rather than harvesting rain?”
