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.
Great to see this focus on aquatic biodiversity (unfortunately the article keeps using the word marine biodiversity, not using the word aquatic or freshwater biodiversity even once) along the 120 km long Sindhudurg Coast line, one of the 11 ecologically sensitive habitats identified along India’s coasts.
The FIRST study of local Otter Population by Ela Foundation identified upto 591 Smooth coated otters (strangely article does not mention about existence of small clawed Otters in Sindhudurg), 561 Indo Pacific humpbacked dolphins, among many others. The coast is particularly river rich with some twelve creeks/ rivers including Shanti, Piyali, Naringre, Achra, Gad, Talavade, Otawane and Pithdhaval Rivers.
In a remarkable development, the National Green Tribunal (NGT) on October 24 has suspended the clearances given to the 1750-megawatt (MW) Demwe Lower Hydroelectric Project (HEP) planned on the Lohit river in Arunachal Pradesh.
In its detailed order, released on October 27, the NGT ruled that the Environment Minister as Chairperson of the National Board for Wildlife (NWBL), a statutory body constituted under the Wildlife Protection Act, 1972, could not “just brush aside” the views of the majority of NBWL standing committee members.
Suspending the clearances given by the Centre and the state govt, the NGT order added that “the decision taken by the Standing Committee is not in accordance with established principles of law and hence the Standing Committee shall reconsider the issue and pass appropriate orders within a period of six months from the date of the judgment”.
Environmental clearance for the project was given by the Union environment ministry’s Expert Appraisal Committee (EAC) for river valley and hydroelectric projects back in 2009. An in-principle forest clearance for the Lower project was given in February 2012 and agreed upon in 2013.
However, the in-principle clearance of the project was opposed by a majority of the Standing Committee of the NBWL but subsequently cleared by the then-environment minister of state (independent charge), Jayanthi Natarajan, who was also the chairperson of the Standing Committee.
Natarajan is currently under the CBI’s scanner for alleged anomalies in clearance given for diversion of land in Saranda forest in Singhbhum district, Jharkhand to mining company Electrosteel during the previous UPA regime.
The NGT said that it is “of the view that either the Chairperson (Natarajan) should have given a proper reason for rejecting the objection of the majority of the non-official members or the decision ought to have been arrived at based on the opinion of the majority of the members. Even though the Standing Committee is a recommendatory body, the same being a statutory committee, is bound by the laudable principles of justice and fair play”.
The latest report of Transparency International reveals that lack of dependable hydrological data, authentic study, action plans giving dual meaning, lack of transparency in the power purchase agreement and a failure to increase the risk-bearing capacity among power developers have remained major hindrances towards the development of hydropower sector in Nepal.
As per the report, the irregularities start from the stages of project selection and identification and this tendency further flourished in the period of a survey and the project implementation, the report states, highlighting a responsible role from the government level to control this practice.
The report also points out that environment standard violations, inadequate compensation in regard to land acquisition, false claims, unreasonable local demands, unwarranted contract variations, bias in selection of top officials like board members and CEOs during the construction, procurement, and implementation phases are working as a catalyst to bring the hydro sector under the grip of corruption.
