Subject: Challenges and dynamics of athaphum: a longitudinal study of Loktak lake in northeast India
Keywords: Athaphum, Loktak, Meitei, Ramsar, spatiotemporal dynamics
Abstract: As the largest freshwater lake in the region and a designated Ramsar site, Loktak lake in northeast India
holds paramount ecological and socioeconomic significance, particularly for the indigenous Meitei community.
This study delves into the intricate spatiotemporal dynamics of a traditional fishing technique called athaphum
practised by the Meitei community in the Loktak. It
utilizes the normalized difference vegetation index derived from the remote sensing satellite images to discern the athaphum and its trend over the past three
decades (1988–2023). Our findings reveal significant
fluctuations in athaphum due to ecological, hydrological and human factors. The findings of this study enhance our understanding of the complexities involved in
safeguarding Loktak lake. They shed light on the intricate balance needed to sustain environmental integrity
and socioeconomic well-being in the Loktak region.

Subject: Empirical evidence for shifting cultivation’s role in indigenous food sovereignty in Manipur, Northeast India
Keywords: Agrobiodiversity, ethnic foods, indigenous food sovereignty, jhum cultivation, Northeast India.
Abstract: Indigenous food sovereignty (IFS) is pivotal in enhancing
food security and nutritional well-being and preserving governance systems and cultural practices within
indigenous communities. Despite its significance, the
literature on food sovereignty practices within Indian
tribal communities and strategies for bolstering them
remains limited. The present study draws upon primary
data collected from 97 households in Manipur, Northeast
India to address this gap. This study employs a mixedmethods research approach and systematically investigates the intricate dynamics of shifting cultivation (SC),
agrobiodiversity and their collective contributions to IFS.
Empirical findings underscore that SC provides culturally relevant food resources, thereby amplifying dietary diversity and contributing significantly to IFS.
The indigenous SC system in the present study site encompasses 32 crop species and 4 local livestock breeds,
featuring numerous landraces that ensure nutritional
security and preserve food culture. Integrating wild
edible plants from forests and fallow lands supplements
the traditional food basket, reinforcing indigenous
food culture and promoting biodiversity conservation.
This study emphasizes the symbiotic relationship between
SC-based agrobiodiversity and dietary diversity and
highlights their critical role in fortifying IFS resilience,
particularly in the context of climate change.

Subject: Optimizing the impact of spray characteristics of hybrid drone on spray deposition in cotton crops
Keywords: Droplet deposition density, operational parameters, spray drift analysis, UAV spraying technology, UAV system
Abstract: The effectiveness of a hybrid unmanned aerial vehicle
(UAV) for optimizing crop booster application on cotton crops (variety Co-14) at Tamil Nadu Agricultural
University is evaluated in this research. The hybrid
UAV, featuring a 12-litre sprayer tank and powered by
an internal combustion engine and brushless direct
current motor, was tested at heights of 1 and 2 m and
speeds of 3 and 4 m s
–1
. The objective was to determine
optimal parameters for maximizing droplet deposition
and minimizing spray drift. The results indicated that
at 1 m and 3 m s
–1
, the droplet density in the target area
was 148 ± 8 drops/cm2
, compared to 136 ± 4 drops/cm2
at 2 m. The volume median diameter at 1 m and 3 m s
–1
was 361 µm, and the number median diameter was
392 µm, showing higher deposition and uniform droplet
sizes at lower heights and lower speeds. Spray drift
analysis indicated reduced off-target movement at 1 m
and 3 m s
–1
, showing a non-target droplet density of
54 ± 4 drops/cm2 compared to 42 ± 6 drops/cm2 at 2 m.
The study concludes that the optimal UAV operation
parameters are 1 m height and 3 m s
–1 speed, enhancing
droplet deposition, minimizing drift, and improving
spray efficiency.

Abstract: In the modern rubber industry, the major problem is
the use of petroleum-derived chemical reinforcements
that exploit conventional sources of energy. In this review article, we have discussed the importance of some
cellulose-based reinforcements as an alternative to
harmful chemicals in rubber composites. The employment of natural cellulosic fillers not only improves
the biodegradability of rubber latex but also enhances
its mechanical and thermal properties. Such reinforced
rubber composites can be used effectively in various
sectors, i.e. food packaging, footwear, water purification and sensors. In the last, the current outlook and
future perspectives of smart rubber composites in
commercial areas are also discussed.

Subject: Will the global focus on methane reduction detract from the global attempts to reduce carbon dioxide emissions?
Keywords: Climate change, CH4 vis-à-vis CO2, global food and nutritional security, small and marginal farmers, survival versus luxury emissions
Abstract: In recent years, the focus on methane (CH4) reductions in the global climate negotiations has grown
significantly. The 26th session of the Conference of Parties (COP26) of the United Nations Framework Convention on Climate Change (UNFCCC) urged countries to consider further actions to
reduce non-carbon dioxide greenhouse gas emissions, including CH4, by 2030, which was reiterated
by COP27 and COP28. This article discusses how an obsessive focus on CH4 reduction is a serious
distraction from the real challenge of limiting and reducing CO2 emissions and masks the inability
of developed countries to meet their commitments. Further, even with regard to reducing CH4 emissions, the article points out that these efforts need to be placed within national contexts and circumstances. In particular, CH4 emission reductions need to focus on energy, industry, and waste sector
emissions rather than the agriculture sector to ensure that there are no adverse consequences for
developmental imperatives such as protecting and enhancing small farmer livelihoods and ensuring
food security. In this context, the article argues that India’s actions on CH4 are entirely consistent
both with her national priorities and circumstances and with the foundational principles of the
UNFCCC, which prioritize the importance of poverty alleviation and sustainable development for
developing countries.

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.

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

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.

Keywords: Decision support system, health status, infrared thermal imaging, muga silkworm, non-invasive
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.
