Can floods lead to drought? After the flood, severe drought looming over Kerala

Guest blog by: Madhusoodhanan C.G. and Sreeja K.G

The state of Kerala experienced extreme precipitation events during the 2018 South West monsoon period with multiple episodes culminating in devastating floods across the state during 14th-18th August 2018. This year, with an early onset of monsoons that dovetailed with strong summer showers, the state received about 41% excess rainfall (2394 mm against the normal of 1700 mm) during the period June 1st to August 22nd [1]. Almost all of its reservoirs were near full storage by mid-July.

The heavy downpour and the uncontrolled opening of the spillway gates of almost all reservoirs that inundated huge stretches of river banks and floodplains, along with massive landslides across the Western Ghats affected more than 1.5 million people, with close to 500 human casualties, immense losses to property, livelihoods and resource security apart from the extensive damage to forests, wildlife and biodiversity. Maximum destruction was observed along the rivers of Periyar, Chalakudy and Pamba, all having multiple dams on their tributaries. The debate is still on as to the various reasons, both manmade and natural, behind the floods and the resultant wide-ranging casualties [2,3,4,5,6]. Meanwhile things have taken a rather unexpected turn in the flood ravaged state.

Feb 2019 Hailstorm, Snowfall Affects Life in Northwest India

Since the beginning of 2019, there have been couple of incidents of hailstorm in Haryana and Punjab. The region has also seen good rainfall in January. The hilly states of Jammu & Kashmir, Himachal Pradesh and Uttrakhand have been repeatedly facing heavy snowfall events gripping the large parts of North India in cold waves.

The initial rains and snowfall were seen usual events and considered as beneficial for rabi crops and water demands. However the unusual hailstorm accompanied by heavy rainfall In January 2019 and again on Feb 7-8, 2019 have caused significant damage to standing crops in large part of Haryana, Punjab and Western parts of Uttar Pradesh.

DRP News Bulletin 21 January 2019: NGT Asks For Audit of Pollution Control Regulation, But Fails on EIA

Two interesting orders from National Green Tribunal (NGT) marked important developments on water-environment issues this week. NGT asking for PERFORMANCE AUDIT of pollution Control Mechanism is indeed long overdue necessity, considering the complete, abject failure of the pollution control mechanism in India. The hopes of effective action, like in the past, however, were dashed since CPCB, which is PART OF THE PROBLEM has been asked to do the audit. An independent audit, in addition to one possibly by CAG may have helped.  https://www.thehindu.com/news/cities/Delhi/ngt-slams-state-pollution-bodies/article26008687.ece (17 Jan. 2019)

Whatever positive signs were available by this order were further dashed by another NGT order in which it declared that EIAs (Environmental Impact Assessment) reports are already taking climate change into account, while the tribunal dismissed a petition asking that all development activities be screened/ regulated keeping climate change in mind.

This is totally WRONG contention. Just to illustrate, SANDRP has been pointing out to the EAC, MoEF and the developers how the EIAs of dams and hydropower projects are ignoring the climate change related issues and impacts. In response the consultants and developers have responded, approved by the silent or spoken nods by the EAC and MoEF that these were not even part of their TORs! One only wishes NGT was most discerning before making such claims and would have gone through a few EIAs to see if at all EIAs are dealing with these issues with any rigour or credibility. https://www.business-standard.com/article/pti-stories/climate-change-already-covered-under-environment-impact-assessment-ngt-119011600897_1.html (16 Jan. 2019)

More bad water news: 2018 Post monsoon rains 44% below normal

Even as large parts of India are facing drought, following deficit North West Monsoon, there is more bad news that farmers already know and experience. The rainfall in the three post monsoon months, from Oct 1 to Dec 31, 2018 at all India level has been 71.2 mm, which is 44% below normal rainfall of 127.2 mm. While the quantum of rainfall in these months is not expected to be high except in some South Indian areas, it is crucial for providing life saving and life sustaining moisture for the Rabi crop. It was particularly important since the second half of the South West monsoon was significantly below normal in large parts of Central and South India[i]. These same areas are experiences biggest deficits in Oct-Dec rains. Continue reading “More bad water news: 2018 Post monsoon rains 44% below normal”

APWRIMS: Impressive Water Information System of Andhra Pradesh

Andhra Pradesh Water Resources Information and Management System[i] is truly impressive water information system, possibly not available in any other state or even at national level, at any time in India. The comprehensiveness of the water information system is striking, as it not only includes reservoir water storages of Major and Medium Projects, but also storages in minor projects, minor tanks, water conservation structures (check dams, percolation tanks) but also groundwater and most importantly, soil moisture. These are collected in real time from diverse information sources including on ground measurements, satellite based assessments and also sent via mobile apps from diverse sources. And the information is put out in real time, along with number of analysis. The data are collated and analysed using tools from Vassar Labs, like Machine learning, Artificial Intelligence and big data.

Monsoon 2018 Overview: Serious Anomalies Hidden by Macro Figures

2018 becomes fifth year in a row when India’s south west monsoon has been below normal.  In the beginning of monsoon season, Indian Meteorological Department (IMD) has forecasted rains to be normal with rainfall equal to 97 percent of the long term average.

The mirage of normal monsoon

According to IMD, India is having normal monsoon this year, so far, as per rainfall till date (Sept 1, 2018). Against normal rainfall of 721.1 mm, India has received 676.6 mm rainfall, which is 6.2% below normal, considered within normal rainfall definition as per IMD. So India is having normal monsoon rainfall, says IMD. Let us check this against some ground realities.

However, East and North East India, one of the four regions for which IMD provides rainfall data, has so far had 27% below normal rainfall, while South India had 9% surplus rainfall.  Thus, while at all India level, what seems all normal, is average of different, though serious departures from normal rainfall. Let us say this is first level of mirage of normal rainfall. Continue reading “The mirage of normal monsoon”
