Keywords: Global Warming Science, quantitative Introduction, climate change
Abstract: Global warming is one of the great challenges human beings will face in the 21st century. Hence young people are concerned about their future in this changing world. Many popular books have been published on this topic, written not for students but the general public. Such books lack academic rigour and do not provide a quantitative understanding of this complex issue. The faculty who teach an introductory course on climate change do not have many good books to recommend to their students.

Subject: Sarus crane Antigone antigone predating on chicks of grey-headed swamphen Porphyrio poliocephalus
Keywords: Crane, diet, hunting, swamphen, wetlands
Abstract: Tropical wetlands host diverse breeding birds, but there is little information on aspects such as the predation of
chicks. Diet of omnivorous waterbirds is poorly recorded in India, especially during the breeding season when they require to hunt more carnivorous foods to facilitate rapid chick growth. In the present study, we observed a sarus crane pair in western Uttar Pradesh, India, predating on chicks of grey-headed swamphen – not reported earlier in the diet of this species. Review of the literature, search of photographs available on the World Wide Web and consulting experts suggested that chicks of other birds are extremely rare in sarus crane diet. Additionally, the existing literature suggests
waterbird chicks as widespread but rare in the diet of cranes globally, though at least one study suspects cranes to be major predators of waterbird chicks. The
chicks of other birds seem to be a ready source of nutrition for omnivorous cranes and the rarity of such predation seems worthy of specific studies.

Keywords: Coastal flooding, mean sea-level rise, new moon and full moon, perigean spring tides, tide-gauge data.
Abstract: Sea level measurements from tide-gauges, installed in harbours along the Indian coast by the Survey of India, are used to illustrate the differences in high tides during spring tides that occurred during lunar perigee and apogee (closest and farthest position of the moon in its elliptical orbit around the earth) in January and August 1974
respectively. The difference in maximum tidal heights between 9 January and 4 August of the year for Mumbai tidal record is about 87 cm, whereas for Chennai, Visakhapatnam and Paradip, the differences vary between 20 and 25 cm. Kochi record shows a difference of about 13 cm, whereas the difference in predicted high tides at
Bhavnagar is more than 1 m. Similar results are found for March and April 1980 during spring tides close to perigee and apogee respectively. Perigean spring tides
can cause flooding in low-lying coastal areas along the northern parts of the Indian coast, which will get enhanced in future with mean sea-level rise due to global warming.

Keywords: Competitive exclusion, management, phylogenetic analysis, Schizotetranychus andropogoni, Schizotetranychus krungthepensis, sugarcane.
Abstract: Following the detection of an incongruity in the nomenclature of sugarcane web mite Schizotetranychus Andropogon (Hirst) (Acari: Tetranychidae), we collected web
mite samples from commercial hybrids of sugarcane and Saccharum spontaneum in parts of Tamil Nadu and Kerala States, India. Acarologists identified these samples as Schizotetranychus krungthepensis Naing & Auger (Acari: Tetranychidae), originally described from Thailand in 2014. To provide molecular evidence to distinguish
S. krungthepensis from S. andropogoni, we subjected sequences of 5.8S rRNA and mitochondrial cytochrome oxidase I (mtCOI) genes of both species available in
NCBI database to Molecular Evolutionary Genetics Analysis (MEGA6). The analysis produced phylogenetic trees with distinct clusters for S. andropogoni and S. krungthepensis, albeit with some exceptions, thus providing evidence to consider S. krungthepensis a species
distinctly different from S. andropogoni. In view of the possible threat of S. krungthepensis to sugarcane cultivation in the country, we outline the basic course of action needed to manage the pest if it were to assume more serious proportions than the native species it appears to be displacing.

Subject: Success of cage farming of marine finfishes in doubling farmers’ income: a techno-social impact analysis
Keywords: Cage aquaculture, livelihood enhancement, marine finfishes, success stories, techno-social impact.
Abstract: In Andhra Pradesh, India, the culture of marine finfishes such as Indian pompano and Asian seabass has been demonstrated in cages in Krishna and Godavari backwaters by the Regional Centre, ICAR-Central Marine Fisheries Research Institute (ICAR-CMFRI), Visakhapatnam, involving fishermen and marginal landless aqua
farmers. Open sea cage culture of orange-spotted grouper and Indian pompano has also been demonstrated in Visakhapatnam, Srikakulam and East Godavari districts
of Andhra Pradesh. From the 14 success stories documented, enhancement in net income in the range 50.32%–257.14% was evident by transforming people from different avocations such as agriculturists, wage earners in agriculture and allied sectors, business professionals, fish traders, traditional fish farmers and artisanal fishers
to marine finfish farming. The benefit ratio of cage farming among the adopted farmers was found to be 1.33 and 1.31 for estuarine and marine cages respectively.
The impact was realized on livelihood enhancement due to the technological interventions of cage culture under
the technological, social and economic dimensions.

Subject: A refined procedure for seismic evaluation and retrofitting of reinforced concrete buildings
Keywords: Adaptive pushover analysis, material strain limit approach, quadrants assessment method, reinforced concrete buildings, seismic evaluation
Abstract: In the present study, a refined procedure for the seismic evaluation and retrofitting of reinforced concrete (RC) buildings based on the ‘quadrants assessment method’ and ‘material strain limit approach’ is proposed and numerically analysed. The quadrants assessment method involves the performance point, design base shear and
threshold damage limit state. Herein, four existing RC buildings (models 1–4) are considered from the Koyna–Warna region, Maharashtra (zone-IV, India). These
four buildings were studied using nonlinear static adaptive pushover analysis employing the SeismoStruct software. Based on the quadrants assessment method,
the three-storey RC building (model-1) was retrofitted with RC jacketing, while the other three RC buildings did not need to be retrofitted. Also, significant seismic
design parameters like ductility, over strength factor, response reduction factor, etc. were evaluated before and after retrofitting. The results depict that the combination of the ‘quadrants assessment method’ and ‘material strain limit approach’ is a rapid, reliable and refined procedure for seismic evaluation and retrofitting of RC buildings.

Keywords: Arc tectonics, geochemical characteristics, mafic–ultramafic complex, petrogenesis, pyroxenite dykes
Abstract: Arc-related origin of pyroxenites in association with Alaskan-type tectonics has been described in many mafic–ultramafic complexes across the globe. The Salem
Mafic–Ultramafic Complex (SMUC) is one such Neoproterozoic Alaskan-type complex exposed at the northern margin of the Cauvery Suture Zone (CSZ), Southern
Granulite Terrane, south India. The Complex consists of mafic and ultramafic sequences along with several occurrences of pyroxenite intrusions of varied thickness in the form of dykes. Similar pyroxenite dykes
were also observed in and around the Complex at several locations within the basement hornblende gneiss, trending in the NE–SW and E–W directions. Petrography of these dykes indicated websterite variety with cumulate textures and reveals the dominance of clinopyroxene along with orthopyroxene, primary amphibole, minor plagioclase and oxide minerals like magnetite, ilmenite and spinels. The whole-rock chemistry of 10
representative samples showed enrichment of LIL elements (Sr, K, Rb, Th) and depletion of HFSE (Hf, Ti, Y, Yb) with normalized primitive mantle and N-MORB. The clinopyroxene mineral chemistry represented tholeiitic signatures with high Mg# values (Mg/(Mg + Fe)) up to 0.91, and the two-pyroxene thermobarometry of
these pyroxenites yielded re-equilibrium crystallization temperatures of 820–932C with moderate pressures at 11–12 kbar. Various tectonic discrimination plots of
clinopyroxene mineral chemistry together with whole rock chemistry favoured their origin under arc settings with the interactions of fluid-related subduction zone metasomatism relevant to Neoproterozoic Alaskan-type tectonics.

Abstract: Strategic planning and execution at the Benti–Bagda Limestone Mine of M/s Jharkhand State Mineral Development Corporation Limited (JSMDCL), India, could
minimize the impacts of surface blasting on structures in nearby sensitive villages to comply with the regulatory requirements leading to resolving the complaints of villagers. Controlled blast design patterns were developed after thorough scientific evaluations using JKSimBlast simulator and blast-compliance software modules to
determine the firing pattern, firing sequence and detonation time versus charge mass (kg) detonated for each
of the three blast-safety zones. The study enabled the mine management to convince the local people to settle their long-pending disputes.

Abstract: As a result of the SARS-CoV-2 pandemic, water bodies connected to anthropogenic activities may likely reveal the presence of viral genetic material. Urban, peri urban and rural water bodies in and around Hyderabad, Telangana, India, were monitored for the presence of SARS-CoV-2 gene fragments during the first and
second wave of COVID-19 infection. The SARS-CoV-2 genes were not detected in peri-urban and rural lakes, whereas urban lakes having direct functional attributes
from domestic activity showed prevalence. Distinct variability in viral load observed among five water bodies was in concordance with human activity in the catchment area. High viral load was observed during the peaks of the first and second waves, specifically in urban
lakes.

Abstract: The Northeastern Region of India (NER) has tremendous scope for accelerating its growth in agriculture and allied areas through advanced data acquisition, interpretation and dissemination methods with geospatial technology. For several thematic applications, geospatial
tools and techniques are being used to provide synoptic, cost-efficient and timely information for effective crop planning and monitoring in the region. A review of space
applications in agriculture, horticulture, sericulture, land-use suitability, shifting cultivation, groundwater prospecting, soil resources management, etc. has been made, highlighting the scope and limitation of using these advanced technologies. Satellite remote sensing has several
limitations in NER, viz. small and fragmented farmlands, persistent clouds during monsoon, mixed farming, steep
hills, etc. Considering these facts, unmanned aerial vehicles (UAVs) are used as an alternative for satellite remote
sensing applications in agriculture. The increased availability of very high-resolution satellite and UAV data will offer opportunities for innovative solutions to fulfil specific user needs of agriculture and allied sectors in NER.

Abstract: This study traces the development of watersheds in India based on the governing guidelines of the watershed programmes. We explore the changes and modifications in the watershed guidelines and categorize the developmental changes into six distinct yet interlinked phases. We observed that the watershed guidelines were fine-tuned with emerging challenges of land degradation, livelihood security, gender and social equity, climate change mitigation and adaptations. Recently, the focus of watersheds has shifted from production centric to income-centric by promoting enabling institutional settings. The experiences and learnings from India’s watershed programmes provide insights for
other developing countries implementing such programmes.

Abstract: This study presents a fossil signature based on fractal dimension (FD) derived from computerized tomography (CT) images to differentiate between coprolites and body fossils. Coprolites are generally studied using destructive techniques like thin section study and geochemistry. Coprolites and body fossils collected from the Triassic terrestrial Gondwana deposits of India
were chosen for the study. The presented CT-powered FD-based digital signature can properly distinguish coprolites from other fossils, without losing the structural features of the samples. The present study will
further enhance the digitalized fossil research.

Subject: Slope stability assessment of the recent Birik Dara landslide in the Kalimpong region of Darjeeling Himalaya, India
Keywords: Failure mechanism, hazard mitigation, landslide, rock mass, slope stability.
Abstract: The Birik Dara landslide occurred at around 10 pm local time (GMT+5:30) on 20 October 2021 on National Highway-10 in the Kalimpong region of Darjeeling
Himalaya, India, and disrupted traffic for more than a week. This study presents an overview of the landslide and reveals the present stability status of the slope. The
slope stability assessment was carried out using data collected from the field during a site visit in the second week of November 2021. The findings of this study indicate that the landslide occurred on a critically unstable slope and it may be triggered again in the near future with more damage. Therefore, immediate attention is required regarding slope stabilization measures to avoid future threats.

Subject: Carbon sequestration potential of two Musa cultivars from Mokokchung, Nagaland, North East India along an altitudinal gradient
Keywords: Allometric equations, banana, biomass, bulk density, carbon sequestration.
Abstract: The present study explores the carbon sequestration potential of two extensively cultivated banana cultivars,i.e. Atsu Mungo and Aot Mungo, from Nagaland, North
East India. The Musa cultivars were planted on experimental plots along an altitudinal gradient. Plant traits such as suckers, number of leaves, height and diameter
at breast height were recorded. The biomass and carbon sequestration potential were estimated using allometric equations. The cultivars had substantial carbon sequestration ability and higher values of sequestration were observed at lower altitudes for both cultivars.
