Subject: Cause of ground subsidence in Machhlipatnam region
Keywords: None
Abstract: Subsidence in coastal (or near coastal) regions is a major hazard1
. Such regions are
becoming more vulnerable in view of the
climate change and rising sea levels2
. It
is necessary to identify the regions susceptible to land subsidence using various methods, recognize the cause of subsidence and
adopt measures to prevent it. There are
several regions or cities in India which are
witnessing land subsidence, e.g. Chandigarh3,4, Delhi5–7
, Kolkata8
, Gandhinagar9
,
Cuttack, Surat, Kochi, Chennai10. In this
correspondence, we report that Machhlipatnam, a municipal corporation of Krishna
district in Andhra Pradesh, ~6 km from the
east coast and ~40 km from the Krishna
river, with a population of 2.3 lakh (as per
the 2011 census), is experiencing subsidence
at an alarming rate of ~10 mm/year since
2017.

Subject: Transforming earth science and engineering: the power of artificial intelligence, data science and machine learning
Keywords: None
Abstract: In the ever-evolving realm of science and
engineering, technological advancements
consistently reshape our understanding and
interaction with the world. A significant
transformation in recent years involves the
seamless integration of artificial intelligence
(AI), data science and machine learning
(ML) into the field of earth science and
engineering. These state-of-the-art technologies are revolutionizing our capacity to
analyse extensive datasets, make predictions and devise sustainable solutions to
address intricate environmental challenges.
Earth science encompasses disciplines such
as geology, climate science, meteorology,
oceanography, and environmental science,
all focused on understanding the earth’s
systems and processes. These fields collectively study the solid earth, atmospheric
phenomena, oceanic processes and environmental interactions to elucidate the planet’s
complex dynamics. Traditionally, researchers in these fields have leaned from labour intensive and constrained manual methods
for data collection and analysis. The advent of AI, data science and ML has ushered in a new era marked by heightened
efficiency and precision.

Subject: Attribution in substance abuse and dependence: does it matter?
Keywords: None
Abstract: Drug use disorders are associated with
significant levels of disease (morbidity)
and disability. They also constitute a burden on national resources and cause immeasurable human suffering. The impact
of the burden is immense and manifold.
According to the World Health Organization (WHO)1
, 5.4% of the world’s overall
illness burden is attributed to alcohol and
illegal substance use. Approximately twelve
million users inject drugs, and an estimated
1.3 million suffer from both human immunodeficiency virus (HIV) and Hepatitis C.
Management of this immense burden is a
herculean task. It includes, in addition to
pharmacotherapy, a host of psychosocial
interventions which are effective in preventing relapse and rehabilitation of individuals
with substance dependence. To mention a
few, they are motivational interviewing,
cognitive behavioural therapy and relapse
prevention treatment2
. But whatever the
management approach, attribution plays a
vital role in understanding substance dependence from varied perspectives. It has been
established that factors related to attribution
impact rates of substance use, as well as the
effectiveness and outcomes of treatment.

Abstract: The usage of synthetic pyrethroid pesticides in harvesting crustaceans and their impact on vast open water systems
have been studied less. Here, we briefly review the rampant use of pesticides targeting lucrative giant freshwater
prawn Macrobrachium spp. in the lower stretch of the River Ganga in West Bengal, India. This is practised
primarily by illegal fishers, releasing commercially available liquid pesticides into the river water. Fish caught
by applying such toxic chemicals can be dangerous for human consumption. In addition, the irreversible adverse
impacts of this illegal fishing on aquatic ecosystems warrant stringent action plans by the government and environmental agencies to protect the aquatic flora and fauna

Abstract: A National Conference on ‘Antimicrobial
resistance: research priorities and action

three decades old Medical College, Hospital and Nursing School, all set up after the
1991 Uttarkashi earthquake.
Vishwa Mohan Katoch (formerly DGICMR and presently at DHR) inaugurating
the conference, provided a fresh perspective on antimicrobial resistance (AMR) as
a major health challenge from the viewpoint of the ‘One Health’ concept. He
pointed out that drug resistance was now
rotating between humans, animals, soil and
water, thereby encompassing the entire environment. Despite the existence of a
Global Action Plan and a National Action
Plan on AMR, only three Indian states
have worked towards evolving their own
State Action Plans.

Subject: Hydrology in the Anthropocene: the Indian context
Keywords: None
Abstract: The term ‘Anthropocene’ was formally coined by Paul
Crutzen (Max Plank Institute for Chemistry, Mainze, Germany) in 2000 to denote the geological era in which humans
have exerted a major influence on natural systems. While
there is no consensus on the time frame of the Anthropocene,
two commonly discussed dates for Anthropocene are
~1750 CE and ~1950 CE (the era of great acceleration in
technology). It is an uncontested fact that the Earth’s environment and climate have been significantly altered by
human-induced changes for a long time attributed to multiple events, e.g. domestication of plants and animals (11.7 ka),
agricultural practices and deforestation (10–5 ka) and
Anthropogenic soils (2 ka). However, the magnitude and
extent of human-induced changes in recent times is unprecedented. In 2009, a group led by Johan Rockstrom (Potsdam Institute for Climate Impact Research, Germany)
advanced the concept of ‘safe operating space for humanity’
and suggested that if the changes in nine identified environmental indicators (climate change) exceed ‘safe limits’,
there may be irreversible changes in the Earth’s environment. More recent work of the operating space (doi:10.
1125/sciadv.adh2458) suggest that all except three boundaries (stratospheric ozone depletion, atmospheric aerosol
loading and ocean acidification) have been violated.

Subject: India needs a better gully erosion map
Keywords: Badlands, gully erosion, gully systems, land degradation
Abstract: Gully erosion affects India widely. Badlands, the most
extreme form of land degradation caused by gullying,
are also observed across large parts of Central and
Western India. Akin to other environmental issues, accurate maps are critical in planning and implementing
land management measures to address gully erosion.
While country-wide gully erosion maps are rare commodities, India is probably the only country having several
datasets including such maps. Gullies and badlands
have been mapped as part of nationwide geomorphological, land degradation and wastelands mapping endeavours. However, upon examination of said maps using
high-resolution imagery on Google Earth, it was found
that they are largely imprecise, with each having false
positive rates (gully erosion mapped where it is not
present) of greater than 70%. It is suspected that the
coarse spatial resolution of the satellite images used
(LISS-III 23.5 m) is the root cause of such low accuracy,
but feature misinterpretation by the analysts might also
have contributed to it. As such, there is little to no reliable information on the magnitude of the gully erosion
problem in India. Therefore, a bespoke high-resolution
gully erosion map is of the essence in India’s drive to
realize land degradation neutrality by 2030

Subject: Bengaluru groundwater fluctuations reflected in crustal deformation
Keywords: Crustal deformation, GPS, groundwater, rainfall
Abstract: The water crisis in Bengaluru is mainly due to a large
deficit in rainfall during 2023. Less precipitation led to
less recharge and subsurface storage. The recharge or
subsurface loading causes elastic deformation of the
crust, namely subsidence during monsoon and its recovery afterward. Such deformation can be measured
using continuous GPS measurements. We see an excellent
correspondence between the trends of Bengaluru rainfall over the past two decades and the vertical surface
deformation derived from the continuous GPS measurements at the IISc site. Decreased precipitation in
2023 led to less annual subsidence than in the earlier
four years when the rainfall increased in subsequent
years from 2019 to 2022, increasing subsidence every
year following the monsoon. The rainfall pattern in
Hyderabad was similar to that in Bengaluru, but in
terms of the magnitude of rainfall and corresponding
crustal subsidence, which was estimated from the GPS
measurements at the HYDE site, it was less pronounced.
These two examples demonstrate the influence of the
hydrological process on the crustal deformation process.

Abstract: The present study has been designed to establish the
thermal profile of complete life cycle of the Antheraea
assamensis (muga) silkworms starting from the eggs to
the moth. The current study also concurrently addresses
the applicability of infrared thermography (IRT) to detect muga larvae infected with pebrine. Because of its
non-contact advantage, IRT imaging can be successfully
manoeuvred to reduce the risk of spreading infections
and ultimately lead to increased silk production. The
images and data obtained by the non-invasive IRT
technology can be implemented, analysed and translated
into deep learning algorithm-based machine learning
called ‘smart data’, which can be fine-tuned to develop
an artificial intelligence (AI) and decision support system (DSS) for the management and monitoring of
silkworms in their entire life progression. Hence, this
will boost their productivity, which will further revolutionize their yearly production and convey attractive
revenues in the global silk picturesque.

Abstract: The urban fringes are experiencing a significant surge
in surface temperature during the transition from rural
to urban, inducing imperceptible disturbances. The
present study analyses the temperature modulations
from 2000 to 2022 in Kalarahanga and Raghunathpurjali fringes in North Bhubaneswar to understand
the relationship between spatiotemporal changes and
land-surface temperature in the fringes. The investigations reveal a consistent decrease in the area under
water bodies and crops, with an increase in the built-up area. Besides, there exists an inverse correlation
between the area under high and medium temperature
with the area under cropland (–0.820) and the area under water bodies (–0.799), and a positive correlation
coefficient (0.813) with the built-up area/impervious
surfaces. This insists on eco-sensitive planning of the
urban fringes with consistent monitoring of land use
and thermal dynamics for apt control of the changes in
the urban microclimate.

examine the water quality of the Tuikual River over
two years (October 2019 to September 2021) at four
sampling stations selected along the river course both
upstream and downstream of the city. The water quality
index was computed as 287, 310, 162 and 135 at sites 1,
2, 3 and 4 respectively. The findings depict that the
river water at all the sites is unfit for drinking because
the weighted arithmetic water quality index exceeds

Keywords: Built-up index, impervious surface area, spatial metrics, urban expansion, urban sprawl.
Abstract: Urban planners study development patterns along with
the rate and type of urban expansion to formulate policies and schemes for planned and integrated future development of the cities. This study aimed to explore the
dynamics of urban sprawl in the metropolitan region
of Kolkata by using Gini–Simpson’s diversity index. It
was used on the generated decadal maps to understand
the degree of spatial concentration or dispersion of the
built areas. It revealed that the urban sprawl was increasing in the outskirts of the Kolkata metropolitan
area (KMA) with gradual dispersion and increased
heterogeneity. A better understanding of the spatial
and temporal dynamics of the city’s growth, provided
by this study, forms the basis for better planning and
effective spatial organization of urban activities for the
future development of KMA.

Subject: Comparison of phytochemical composition and anti-hyperglycemic activity of Liubao tea from different fermentation years
Keywords: Anti-hyperglycemic activity, enzyme inhibition, Liubao tea, phytochemical composition, PI3K-Akt pathway
Abstract: Using response surface methodologies, two Liubao tea
(LBT) extracts, LBT-5 and LBT-7, were optimized for
different fermentation durations. Phytochemical composition analysis assessed the chemical composition
and distribution of tea pigments. Their inhibitory effects
on glucose-metabolic enzymes were analysed. Furthermore, an insulin-resistant (IR) cell model was constructed to study their regulation of glucose metabolism
and underlying mechanism. LBT-7, aged longer, exhibited higher polyphenols and pigments. Assessments
on glucose-metabolic enzymes and IR regulation confirmed LBT’s capability to enhance glucose consumption, modulate cytokines and activate the IRS-PI3KAkt-GLUT4 pathway. Notably, LBT-7 demonstrated a
stronger effect due to its higher tea pigment.
