This week there are exemplary and encouraging wetlands revival stories from three metro cities of Chennai, Hyderabad and Delhi. In the first example from Hyderabad, meticulously chosen plant species such as tulsi, aswagandha, citronella and hibiscus have been used to create an artificial island to clean Neknampur Lake. The treatment islands are composed of four layers of which the bamboo base keeps the entire structure afloat. Based on soil-less hydroponics, these floating treatment wetlands absorb excess nitrates, thereby reducing the chemical content of the lake water. Microorganisms present in the wetland break down organic matter while the root systems filter out pollutants and sediments. https://www.thenewsminute.com/article/3500-saplings-floating-islands-help-rejuvenate-hyd-neknampur-lake-75819 (The News Minute, 3 Feb. 2018)
Similarly, Chennai-based Care Earth Trust along with the public works department (PWD) and the civic body has managed to restore three urban lakes. While many of the smaller wetlands have vanished over time, many mid-sized wetlands seem to have shrunk by almost 65 percent. Thanks to their joint effort, invasive hyacinth was removed from the Narayanapuram Lake in Pallikaranai, while sewer lines, which emptied into the Perungalathur Lake, have now been plugged. A detailed restoration proposal has been forwarded to the PWD regarding the Korattur-Madhavaram-Ambattur lakes. https://timesofindia.indiatimes.com/city/chennai/hyacinth-out-sewer-line-plugged-three-water-bodies-restored/articleshow/62748110.cms (The Times of India, 2 Feb. 2018)
Meanwhile, Delhi Jal Board (DJB) has taken up interesting new project of creating an artificial lake in Dwarka. The project will supply water in sub-city and improve ground water level too. DJB has approved Rs. 56 crore for the project which will be completed in next seven months. This would the first model project wherein a lake will be used to augment water supply. The special lake is being created next to the Dwarka water treatment plant (WTP) will have a sand bed to allow maximum percolation of water into the ground. It will have a capacity of 10 million gallons (MGD). The project is expected to add supply of 5-6 million gallons water to Dwarka every day.
Water conservation: Lessons from ancient IndiaAs drought-like conditions have gripped many parts of India this year, the pressure to drill borewells in search of increasingly scarce groundwater has escalated. Many regions are in the grip of a vicious cycle of drilling causing the water table to sink further. There is an urgent need to explore what benefits water conservation can bring, whether through modern or ancient water storage structures. This report explains, ecologically safe engineering marvels of water conservation have existed in India for nearly 1,500 years, including traditional systems of water harvesting, such as the bawari, jhalara, nadi, tanka, and khadin. Even today these systems remain viable and cost-effective alternatives to rejuvenate depleted groundwater aquifers, according to experts. With govt support, these structures could be upgraded and productively combined with modern rainwater-saving techniques such as anicuts, percolation tanks, injection wells and subsurface barriers. This may be a far more sustainable approach to alleviating the water scarcity crisis across India. Ultimately, water conservation has to be a key element of any strategy to bring an end to India’s perennial swings between drought and flood.
On May 4-5, 2016, Lok Sabha Speaker Smt Sumitra Mahajan took the lead in organising a workshop for Members of Parliament on Drought, Agrarian Crisis and ILR. As part of the newly constituted Speaker’s Research Initiative’s (SRI for short) work, Smt Mahajan inaugurated the workshop at 4 pm on May 4, 2016, where a panel of eight speakers were invited (4 on each day, SANDRP coordinator was one of the invited speakers on 1st day) to share their views, followed by questions from Members of Parliament. The idea was that on these important issues, Parliament Members are better equipped to raise the relevant issues when debating and raising questions in Parliament. It was heartening to see that at least 90 MPs (88 from Lok Sabha and 2 on Rajya Sabha) were present for 2.5 hours on first day, and they wanted to ask so many questions that there was not sufficient time to allow all of them to ask, nor sufficient time for speakers to make full presentations or answer all the questions. Similarly on second day too Speakers showed lot of interest on these issues. While inaugurating the workshop, Smt Mahajan mentioned how in Solapur, Maharashtra, because of the work of the collector and his team of officials, the impact of drought is lower than that in other districts. This was certainly heartening since it was SANDRP Associate Coordinator Parineeta Dandekar who first wrote on this issue, following her visit to Solapur and interview with the district collector. The workshop highlighted the need for many such workshops, possibly more focussed, but the impact of the workshop was already visible in the (as yet unfinished) debate under section 193 that started in Lok Sabha on May 5, 2016, hopefully to be continued in current week.
