13th-century water body in Delhi dying for lack of attention, sustained revival plan (downtoearth)

One of the most historical water bodies, Hauz-e-Shamsi, is shrinking. Residents around this water body fear its extinction. Once spread over 100 hectares, this water body (locally known as the Shamsi talaab) has shrunk into a patch of filthy water over the years. Rainwater from nearby catchments is the only source of water to the lake. Due to concretisation, there has been a massive loss in water restored to the lake. “Loss of catchments, dumping of waste, sewage discharge and lack of political will are some of the cited reasons behind the present state of Shamshi talab,” says Lalit Gupta, secretary of the Shamsi Talaab Resident Welfare association (Mehrauli).

The water reservoir comes under the purview of the Archaeological Survey of India (ASI). “Seeing the dismal state of water body, we went to the ASI for support for cleaning and maintaining sufficient water by redirecting surplus water from nearby sewage treatment plants. We only got assurance of regular cleaning, which was also not taken up after 2015. Despite all promises, nothing is done on ground,” adds Gupta. Praveen Singh, superintending archaeologist at ASI has a different narrative, “We are working on cleaning and restoring the water body and nearby monuments. The water-related issues such as desilting and refilling are not in our jurisdiction. We are planning to work in collaboration with Delhi Jal Board (DJB) to look into this matter. To facilitate the process, we are also interested in making provision of funding as well.”

There are channels and drains that are connected to the reservoir to divert rainwater from available catchments, but this is not sufficient enough to maintain appropriate level of water. To address this, community came forward and started a local initiative led by the association. They targeted municipal sewage drains that collect sewerage from neighboring colonies. This drain is present along the lake. To treat sewage water and to use treated water to fill lake, members of the community established a decentralised sewage treatment plant (STP) by spending Rs 60,000. After initial operationalisation of four to five months, they found that the water level rose upto to 10 feet. The regular water quality monitoring was also done by the residents itself. But ASI officials closed the unit and promised a new treatment system in collaboration with DJB in due course of time. “Till date, no work has been undertaken by either DJB or ASI. They are just empty promises and nothing more than that,” adds Gupta.  

V K Jain, founder of Delhi-based non-profit Tapas, who moved court for saving Delhi’s lake and water bodies, says, “We received order from courts for cleaning water bodies several times, but a regular monitoring and cleaning is never done. Initially, it was done for two or three year, but then the programme stopped. Frequency was never maintained for cleaning activities, hence, whole exercise lost its value.” Even if the lake is cleaned regularly, the concern is the lowering water level. It is time we realised that if water level is not maintained, the remaining aquatic life in the lake will soon disappear. “Treated wastewater available from nearby operational STPs with BOD (biological oxygen demand) level less than 3 mg/L can be a good alternative to filling the lake,” adds Jain.

The present situation of Shamsi Talab is a result of the apathy of government agencies. Once a water-sufficient lake now looks like an unhygienic, mosquito-breeding site full of aquatic weeds. Apart from creating awareness, there is an urgent need to make provision for water supply to the lake, in addition to regular cleaning and desilting. Otherwise, it will soon be lost and turn into a dry dumping ground.

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment]. Having

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i
