DRP: 19 Oct 2020: India Rivers Week 2020: IS SAND MINING KILLING OUR RIVERS?

India Rivers Week (IRW) Organising Committee is excited to announce that the theme of the forthcoming annual event IRW 2020 will be: “Is Sand Mining Killing our Rivers?”. As part of IRW-2020, India Rivers Forum is organizing a series of Dialogues (digitally). This includes four regional dialogues focusing on North (Oct 31), South (Nov 7), West (Nov 12) and East (including North East: Nov 21)) India, and the final one (Nov 28) focusing on Sand Mining as a National issue.

Sand mining or mining of River Bed Material (RBM, including sand, gravel, boulders) has a huge impact on Rivers, in multiple ways: physical, ecological, livelihood impacts among others. While sand is also sourced from sources other than rivers, IRW 2020 will focus on sand sourced directly or indirectly from rivers. Sand is by definition, a key ingredient of the rivers. It provides habitat for multiple species of the biodiversity in the river. It provides both sub surface storage space and a mechanism to recharge the groundwater. The sand, along with silt, clay, pebbles and boulders are part of the river and are supposed to reach the deltas and provide a key existential medium in floodplain and deltas. To achieve that, sustaining river connectivities is very important.

Cloud Bursts in Indian Himalayan Region in Pre-monsoon & Monsoon 2020

The Indian Himalayan region has been facing increased cloud burst incidents for past many years. These events are followed by flash floods, landslides causing widespread damages to human lives and properties. However the forecasting, monitoring and management efforts are lagging far behind. This state wise overview attempts to understand the trend and resultant losses from such incidents during the pre-monsoon (Apr-May) southwest monsoon season (June-Sept) 2020.

SANDRP has been highlighting the issue since 2018. The details of these can be seen by exploring the hyperlink of Uttarakhand in 2018 and 2019, Himachal Pradesh 2019, Jammu and Kashmir and North East 2019.

DRP: 12 Oct 2020: Why is India’s flood forecasting system ineffective?

This scholarly article shows why India’s flood forecasting system is ineffective. It is not location specific, provides too short a time, it does not provide the intensity of flooding, it is not comprehensive, there is no independent assessment. As far as dams are concerned, its performance is worst, and is unable to either expose wrong dam operations or take action against such operations. Its inflow forecasts are most of the time non existent. It makes numerous errors, but fails to correct them for long time. Its website is slow, sometimes totally non functional. It keeps changing the monitoring sites, their HFLs and provides neither consistency nor reasoning for many of its actions. In the middle of the monsoon it decided to curtail the hydrographs and information display system. Read on.

In 2020, south west monsoon season when rainfall was 8.74% above normal, rivers reached new Highest Flood Levels (HFLs) at least at 37 locations across the country, as per information available to SANDRP. Maximum 13 such instances come from Central and East India, each. Five instances happened in South India, three in North India and two in North East India. This article provides wise details and hydrographs of all these sites.

SANDRP has been tracking the Highest Flood Level (HFL) breach incidents during monsoon season. The analysis of such HFL breaches in 2018 and 2019 are available on our website. In 2018 we had listed 25 such instances though SW Monsoon rainfall was 9.4% below normal. In 2019 we listed 37 such instances when the SW Monsoon rainfall was 10% above normal.

DRP: 21 Sep 2020: IHA President accepts-Hydro faces massive slowdown & worse

International Hydropower Association (IHA) is essentially global leader of hydropower lobby. So when IHA President Roger Gill speaks about the problems hydro industry is facing, it becomes very interesting for all concerned.

In this interview the Roger Gill makes it clear that Hydro investments have been slowing down in last five years when compared with investments in immediate earlier decades. It has further slowed down in 2019 and has been further majorly affected by Covid-19 pandemic. Gill also accepts that the hydro is perceived as much more risky compared to solar and wind. The claim he makes of low levelised cost of electricity from hydro projects is a bit of fiction, since cost of any under construction or new hydro will be hugely costlier than solar and wind power projects. The IHA president is catching at the straws when he takes encouragement from investments in existing hydro projects and pump storage, though he keeps making it clear that market is still unclear as far as pump storage tariffs are concerned. A friendly interview also reveals a lot!!

It is high time that the Indian hydropower lobby led by NHPC and power ministry takes due note of the realities and would not push unjustified, unviable and destructive hydropower projects down the throats of reluctant states and people, using scarce public resources.https://energy.economictimes.indiatimes.com/news/power/hydro-power-requires-100-bn-investment-annually-roger-gill-international-hydropower-association/78131561 (17 Sep 2020)

DRP: 14 Sep 2020: How should we define a Normal Monsoon?

IMD is happy to declare a monsoon as normal as long as total quantum of rainfall at national scale is within 4% of what is defined as normal monsoon rainfall during June 1 to Sept 30. Even if this means there is spatially or temporally or both spatially & temporally, the total rainfall or its distribution is abnormal in large parts of the country. It was good to see a national newspaper, asking question if the monsoon is normal even though it’s not temporally normal as was the case in large parts of the country this year.

The IMD normal only assures meteorological normal of national monsoon rainfall within given period. It does not assure hydrologic normal nationally or in different parts of the country, nor agricultural normal rainfall nationally or in different parts: sub divisions, states, river basins, districts, talukas/ tehsils or villages and wards. We clearly need much more realistic and nuanced definition of even meteorological Normal monsoon rainfall, which IMD needs to work on. But as far hydrological or agricultural normal rainfall is concerned, both temporally and spatially, those concerned outside IMD will need to work on.

DRP: 7 Sep 2020: On Himalaya Diwas, will Supreme Court stop destruction of Himalaya by Char Dham Road?

The people and state government of Uttarakhand would be celebrating Himalayan Diwas on September 9; the Supreme Court of India would be hearing the issues related to the controversial Char Dham Road project a day before it on September 08. During the last hearing on August 31, the apex court has rescheduled the case by extending the hearing date by a week amid concerns of recurring landslides raised by the petitioners.

The ongoing adverse impacts on forests, rivers, streams, soil covers, hills and people continue to concerns scientists, geologist who are alarmed by the scale of destruction and shocked by the brazen manner the state and central governments have been marching ahead without bothering to assess the impacts or address the genuine issues being raised by all concerned.

Multiple reports have been showing that the deliberate dilution of environmental rules and violations of already weakened norms applied by none other than governments themselves to avoid scientific scrutiny and push the project through climatically and ecologically sensitive mountains is proving to be a Himalaya blunder. There is still time to pause, ponder, review the project, assess the impacts, reduce road width and prepare an action plan to restore the damages and pay heed to scientific suggestions before the blunder leads to another inevitable disaster of Kedarnath or larger scale. Hope the apex court would not fail Himalayas.

District wise rainfall in June-Aug 2020 in India

In the ongoing South West Monsoon, India received 44 year old high surplus rainfall of 327 mm in just concluded Aug 2020, 26.6% above normal rainfall of 258.2 mm. This helped the total June-Aug 2020 rainfall to achieve 10% surplus, with actual rainfall 780.3 mm, 69.9 mm higher than normal rainfall of 710.4 mm. In June the country received 18% above normal rainfall and in July it received 9.9% below normal rainfall, the rainfall at the end of June was just 1.1 mm above normal. Thus almost the entire surplus rainfall is thanks to the rainfall during Aug 2020. The rainfall distribution has however, been far from normal that these figures suggest, as we can see from the state wise and district wise figures below.
