Heavy Rainfall in India in Oct-Nov 2021
India has seen rather heavy rainfall in October and November 2021, with October All India Rainfall being 33% above normal and November rainfall being record breaking 86% above normal. The combined Oct + Nov Rainfall was 48% above normal, and by Dec 7, as we write this, it is already 53% above normal for the period from Oct 1 to Dec 7, 2021.
While lingering South West Monsoon brought large part of the excess rainfall in first half of October, the unusually active North East Monsoon with continuous supply of moisture from Bay of Bengal has been the main reason for the high rainfall since late October. The onset of La Nina has also contributed to this and with La Nina forecast to remain in place till March 2022, we are in for continued wet spell in South India, it seems. IMD has already forecast above normal rainfall in South Karnataka during Dec 2021 to Feb 2022.Continue reading “Heavy Rainfall in India in Oct-Nov 2021”

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.Continue reading “Post Monsoon 2020: State wise Rainfall”
DRP NB 7 Dec 2020: Courts expose NEXUS and IMPUNITY in Sand Mining. Will any commensurate consequences follow?
Four different news on River Sand Mining catch our eye, with common underlying theme of NEXUS of government and miners on the one hand and IMPUNITY of the sand miners in indulging in mindless violence. In Madhya Pradesh and Uttar Pradesh, no less than the Supreme Court (SC) and National Green Tribunal (NGT) respectively expose nexus between the state government and illegal sand mining. In Agra (UP again) the sand miners have again shown impunity in attempting to crush the forest officials trying to stop incessant illegal river sand mining from Yamuna River, they managed to run away, as usual. In Tamil Nadu, the High Court has appointed an advocate to ascertain the extent of illegal mining.
On any day, and in any sector, this should have been seen as eye widening affairs. It indeed should. But in sand mining this seems like regular dog biting man kind of news. One hopes it is not and that serious consequences follow. Kind of consequences that would not only help bring commensurate punishment to those responsible, but before that the identification of the guilty. And that punishment will be exemplary enough to bring some fear into the sand miners and those indulging in corruption in sand mining. It’s a bit tall order, but not unwarranted.Continue reading “DRP NB 7 Dec 2020: Courts expose NEXUS and IMPUNITY in Sand Mining. Will any commensurate consequences follow?”
South Zone Sand Mining Dialogue: The grain of sand is habitat for many lives
One of the central themes of the lively presentations and discussion at the South India Sand Mining Dialogue was that the grain of sand is a habitat for so many lives, as so brilliantly put forward by Munmun Dhalaria, one of the panelists. Another key highlight was that Yogeshwaran, the lawyer painfully noted that sand mining laws are neither environment friendly nor people friendly and can be environment friendly only if they are people friendly.Continue reading “South Zone Sand Mining Dialogue: The grain of sand is habitat for many lives”
