Over the course of past two years, series of disasters and accidents have taken place at construction site of the controversial 2000 MW Lower Subansiri Hydro Power Project resulting in damages to project structure and death of construction workers thus raising questions over its safety and sustainability. Since 2005-06, the largest ever under-construction hydropower project is being developed by NHPLC Ltd (formerly known as the National Hydro Power Corporation Limited), a central government company in geologically fragile, seismically vulnerable and biodiversity rich area in the face of pending judicial case[i] and very strong opposition from people across the Assam.
The latest disaster in form of a massive landslide affected the project site on October 12, 2022 further delaying the repair works which were being carried to recover damages caused by the flash floods, landslips at dam site in last week of September 2022.

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.

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.

Improper operations of dams, disasters related to dams and hydro projects and breaching of embankments have been aggravating flood disasters during every monsoon. There have been several such incidents during South West Monsoon 2020, taking heavy toll on people and property which could have been avoided or impacts reduced in many cases with proper dam operations and proper maintenance of the embankments. This compilation attempts to put together all such instances when avoidable flood disasters were created by improper operation of dams and breaching of embankments in the south west monsoon 2020.

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.
