Glacial Lake FLood destroys Teesta-3 Dam in Sikkim, brings wide-spread destruction
A Glacial Lake Outburst Flood (GLOF) that originated at South Lhonak Glacial Lake at around 00.40 hours on Oct 4, 2023, washed away the 60 m high dam of Sikkim’s biggest hydropower project, the 1200 MW Teesta 3 HEP. The flood has brought unprecedented disaster all along the river in Sikkim and further downstream in W Bengal and then Bangladesh. Central Water Commission (CWC) reported early in the morning of Oct 4 that there was cloud burst at the site of the lake burst, the cloud burst could have played the role in triggering the lake burst.

Post Monsoon 2020: State wise Rainfall
According to India Meteorological Department (IMD), during the just concluded Post Monsoon Rainfall for 2020, that included rainfall during Oct-Dec months, India received 124.6 mm rainfall, 0.64% above the normal rainfall of 123.8 mm during the period. As per IMD[i] definition, the rainfall was thus normal.
This three-month period from Oct 1, to Dec 31 includes the North East Monsoon that mainly affects parts of South India including Tamil Nadu, Puducherry, Rayalseema, parts of Karnataka and Kerala. IMD declared on Jan 1, 2021 that the of NE Monsoon ended on Dec 31, 2020 with normal overall rainfall: TN had 6% above normal, Karnatak 13% above normal, Puducherry 32% above normal, Andhra Pradesh 33% above normal. However, Lakshadweep had 9% below normal and Kerala 26% below normal. This monsoon provides 48% of the annual rainfall of TN so it is most imp for that state.
The rainfall revived only towards the end of November, mainly due to two consecutive cyclones — Nivar and Burevi — both of which developed in the Bay of Bengal. While Cyclone Nivar crossed the coast close to Karaikal near Puducherry and brought heavy showers for the east and coastal districts of Tamil Nadu, Cyclone Burevi weakened before it reached land.

East Zone River Sand Mining Dialogue: How can we ensure implementation of court orders?
Higher Courts and NGT has been giving numerous orders and judgments, but the state is happily getting away with non implementation in most cases. How can we ensure that court orders get implemented? Why is the judiciary not concerned about non implementation of its orders? This was one of the central message of the East Zone River Sand Mining Dialogue on Nov 21, 2020 (4-6.30 pm) as part of the India Rivers Week 2020[i] theme “Is Sand Mining Killing our Rivers?” Additional Director R B Lal from Union Ministry of Environment and Forests in his presentation agreed that the sustainable sand mining guidelines have not been implemented. One would have liked to hear how we can achieve their implementation and that MoEF also values participation of people at the grass roots in sand mining governance. He did not mention the local people even once, while praising MoEF’s emphasis on technology in the sand mining guidelines.
The Dialogue was very ably moderated by Dr Malavika Chauhan of Tata Trusts and Dr Debashish Sen of People’s Science Institute (Dehra Dun). This was Fourth in a series of Zonal River Sand Mining dialogues being held after North Zone[ii], South Zone[iii] and West Zone[iv] Dialogues held earlier.

SW Monsoon 2020: District Wise Rainfall
India received 957.6 mm rainfall in Just concluded South West Monsoon 2020, during the scheduled 4 month monsoon from June 1 to Sept 30, 2020. This is 8.74% above normal monsoon rainfall of 880.6 as per India Meteorological Department (IMD). This is considered ABOVE NORMAL rainfall, since rainfall is in the range 4-10% above Normal rainfall. This sounds good at national level, but the situation on ground could be very different, if we see the rainfall across the country.
It is noteworthy as per even IMD, monsoon has not yet withdrawn from most parts of the country. But IMD closes its monsoon rainfall account at 0830 hours on Sept 30, so all rainfall after that hour has to be counted in “Post Monsoon” rainfall book, even though the rainfall is very much part of monsoon as per IMD.
