In the just concluded Winter Season (Jan 1 2021 to Feb 28 2021), as per India Meteorological Department (IMD), India received 32% below Normal Rainfall. The Normal rainfall in this two-month season is supposed to be quite low at 40.8 mm, but the actual rainfall was just 27.8 mm, which means rainfall was less than 0.5 mm per day in the season. Out of this the Rainfall in January 2021 was 20.2 mm, 17% above the normal rainfall of 17.3 mm. So in February 2021, the rainfall was 7.6 mm, against the normal rainfall of 23.5 mm, so the February rainfall was 68% below normal!Continue reading “District wise Winter 2021 Rainfall in India”
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”
River Sand Mining is equivalent to mining not only riparian health, but also destroying massive water storage and recharge capacity. This was one of the central message of the West Zone River Sand Mining Dialogue on Nov 12, 2020 (4-6.30 pm) as part of the India Rivers Week 2020[i] theme “Is Sand Mining Killing our Rivers?” The other central message of the West Zone Dialogue was well encapsulated by this quote from Yamuna Sunny, one of the panelists at the Dialogue: “The intricate relationships between the fishers, the small scale sand miners, the sand farmers, the birds and the trees, pertains not only to possibilities of developing sustainable ways of human life in an economic sense, but also the sustaining of all life forms and their relationships in nature.”Continue reading “West Zone River Sand Mining Dialogue: Mining Riparian Health”
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.Continue reading “SW Monsoon 2020: District Wise Rainfall”
We showed on Sept 2, 2020[i] using official information that Sardar Sarovar Dam (SSD) created an avoidable flood disaster in Bharuch, downstream of SSD starting on Aug 29, 2020, due to sudden, adhoc release of massive quantities water upto 10.72 lakh cusecs. The Sardar Sarovar Narmada Nigam Limited (SSNNL), official agency responsible for operation of the SSD is yet to provide any clear, coherent and fact based response. However, some of the spokespersons of SSNNL/ Government of Gujarat (GOG) are claiming that scientific operation of SSD saved Bharuch from bigger disaster. While this claim has no basis, this is like spraying salt on the fresh wounds.
Only an independent (not by serving or retired bureaucrats of the government) investigation would be able to bring out the truth as to how SSD operated, how it should have been operated, who is responsible for the massive disaster that Bharuch experienced, how can we fix accountability and what lessons we can learn for future.Continue reading “SSD induced Bharuch Flood disaster: Reality behind SSNNL claims that it saved Bharuch”
સરદાર સરોવર ડૅમ (SSD)ના સંચાલકો જરાય વિચાર કર્યા વિના, અને કહી શકો કે, ક્રૂરતાથી, પાણી કેટલું છોડવું, ક્યારે છોડવું તેના નિર્ણયો લે છે. એમના નિર્ણયની અસર હેઠવાસમાં શું થશે તેના પર તો જરાય ધ્યાન નથી આપતા. કંઈ નહીં તો, ૨૬મી ઑગસ્ટ ૨૦૨૦થી જ એમને સત્તાવાર માહિતી મળી ગઈ હતી કે ભારે વરસાદને કારણે નર્મદાના ઉપરવાસમાં પાણી વધવા લાગ્યું છે. આ માહિતી પર એ કામ કરી શક્યા હોત તેમ છતાં ૨૯મી ઑગસ્ટ, શનિવારની વહેલી સવાર સુધી એમણે ડેમનાં સ્પિલ-વે ગેટ્સમાંથી પાણી ન છોડ્યું. ડૅમ ૭૦ ટકા ભરાઈ ગયો હોવા છતાં એમણે પાવર હાઉસો પણ ન ચલાવ્યાં. ઓચિંતા જ ૨૯મીની રાતે એમણે દસ લાખ ક્યુસેક – દર સેકંડે ઘન ફૂટ (૨૮,૩૨૦ ક્યુમૅક એટલે કે દર સેકંડે ઘન મીટર) પાણી છોડવાનું શરૂ કરી દીધું [i].. ત્રણ દિવસ પછી ૧ સપ્ટેમ્બર, મંગળવારની સાંજે એમણે મોટા ભાગનાં સ્પિલ ગેટ બંધ કરી દીધાં. આમ સ્પિલ-વેમાંથી નીકળતા પાણીનો જથ્થો પહેલાં કરતાં માત્ર દસમા ભાગનો રહ્યો. આ ૩-૪ દિવસમાં (૨૯મી ઑગસ્ટ અને ૧લી સપ્ટેમ્બર વચ્ચે) પાણીનો ૩૦,૦૦૦ ક્યુમૅક સુધીનોજબ્બરદસ્ત જથ્થો સ્પિલ-વે મારફતે છોડવામાં આવ્યો; એના પહેલાં કે તેના પછી કંઈ જ નહીં! પરિણામે હેઠવાસમાં ગરૂડેશ્વરથી ચાંદોદ અને ભરૂચ સુધી પૂરનાં વિનાશકારી પાણી ફરી વળ્યાં. પરંતુ લાગે છે કે, સરદાર સરોવર પ્રોજેક્ટ (SSP)ના સત્તાવાળાઓ અથવા ગુજરાત સરકારના પેટનું પાણી પણ નથી હાલ્યું. હવે સમય આવી ગયો છે કે ગુજરાતની જનતા જાગે અને આ માનવસર્જિત તારાજી માટે SSPના ખેરખાંઓનો જવાબ માગે.Continue reading “ભરૂચમાં પૂરની તારાજી માટે સરદાર સરોવર જવાબદાર”
Sardar Sarovar Dam (SSD) operators are operating the dam callously, almost cruelly, without consideration of the impact of the operation in the downstream area. Till Saturday-Aug 29, 2020 early hours, they were not releasing any water from the spillway gates of the dam, in spite of sufficient actionably information at least since Aug 26 that rainfall is hugely increasing in upstream Narmada basin. They were not even operating powerhouses even though the dam was close to 70% full. Suddenly, by Aug 29 night they started releasing upto ten lakh cusecs – Cubic Feet Per Second (28320 cumecs or Cubic Meters per second) of water[i]. Three days later, in the evening of Tuesday, Sept 1, they closed most of the spillway gates, thus reducing releases from spillway to less than a tenth of the earlier figure. During these 3-4 days (Aug 29-Sept 1), massive quantities were released, upto 30 000 cumecs through spillways, and almost nothing before or after! It created massive flood disaster all along the downstream from Gaudeshwar to Chandod to Bharuch, but the Sardar Sarovar Project (SSP) authorities or the Gujarat government seem least bothered. It is high time people of Gujarat wake up and hold the SSP operators accountable for this man made disaster.Continue reading “Sardar Sarovar Creates avoidable flood disaster in Bharuch”
