Subject: Emerging from the Yamuna – studying an erstwhile oxbow lake in Sersa, Haryana, India
Keywords: Ground truth survey, land-use patterns, oxbow lakes, palaeoclimate, remote sensing.
Abstract: Oxbow lakes in the Indian subcontinent are niches rich in biodiversity, and contain insights into the palaeoclimate and past settlement patterns of the region. This study examines an erstwhile oxbow lake in Sonipat, Haryana, India, which possibly arose from the former course of River Yamuna. The study first confirms the presence of this lake using satellite imagery to identify its remnants. It also employs various pathways, including elevation data, Corona imagery and Survey of India maps, to discern the path of the lake in today’s geography of Sersa. The reason for its disappearance has also been accounted for in this study. Apart from using satellite evidence and GIS, an on-site ground truth survey was also conducted, the results of which are discussed. Finally, further suggestions for research are provided to understand the palaeoclimate of the study site. It is also significant that this would be an understudied avenue of research on such a feature in Sonipat.

Subject: Blossom midge Contarinia maculipennis Felt infesting tuberose (Agave amica) flowers in India
Keywords: Bioecology, blossom midge, DNA barcoding, midge fly, morphology, tuberose b
Abstract: Tuberose (Agave amica (Medikus) Thiede and Govaerts) is a hardy and economically important flower crop in India. Tuberose growers have been facing severe loss in flower yield due to the large-scale deformities and rotting of buds caused by midge fly attacks. Morphology and DNA barcoding have confirmed the identity of this midge species as Contarinia maculipennis Felt (Diptera: Cecidomyiidae). Maggot feeding causes deformation and rotting of the infested buds and imparts an ugly appearance to the tuberose florets. Midge fly infestation ranged from 5.67% to 88% from July to September 2022 in different tuberose-growing areas of Maharashtra, Telangana and Andhra Pradesh in India. The bioecology of this midge species and the nature of damage to tuberose were studied to develop eco-friendly management methods. This study offers novel insights into the nature and extent of midge damage to tuberose and how midge symptoms differ from tuberose melody symptoms caused by the foliar nematode.

Subject: Species composition of frugivorous insects of citrus and attractant–repellent-based management of primary fruit piercer, Eudocima materna
Keywords: Citrus, Eudocima materna, frugivorous insects, fruit drop, species composition
Abstract: Studies were conducted to understand the preference of fruits by fruit-piercing moth (Eudocima sp.) and the efficacy of repellents/deterrents for the management of insect-pest-related fruit drop in citrus. The activity of Eudocima sp. was observed between August and December, with the most damage occurring in September (13.35%) and October (21.5%) during the color-breaking stage of Nagpur mandarin. Foliar application of petroleum spray oil at a rate of 2% or neem oil at a rate of 1% every two weeks during the color-breaking stage until harvest significantly reduced fruit drop (48.0%– 70.0%) caused by the fruit-piercing moths. Simultaneously, hanging two polypropylene sachets with phorate or acephate, 10 g per tree, during the ambia (spring) season also significantly reduced fruit drop (<7%) due to the moths.

Subject: A cost-effective, modular, research-grade optical microscope
Keywords: Clinical diagnosis, imaging modalities, modular optical microscope, open-source software, research and pathology.
Abstract: Optical microscopy is a ubiquitous tool in the physical and life sciences and in histopathology, where visible light microscopy is used to analyse clinical tissue sections at the micron scale to help diagnose diseases. In recent years, microscope technologies have dramatically evolved, but these have generally come with increased cost and complexity. To widen access to advanced microscopy capabilities, we have developed a cost-effective modular platform for optical microscopy (www.openscopes. com). Many of these instruments can be based around a new low-cost and flexible microscope stand, ‘openFrame’, for which the core components are open source. openFrame can support implementations of a wide range of microscope modalities for diverse applications, including research, pathology and training. Unlike many commercial microscopes that are often designed for specific applications and cannot be easily upgraded or adapted for different imaging modalities, openFramebased instruments can be relatively easily maintained, upgraded or adapted to another modality without requiring manufacturer support. To this end, openFramebased instruments are envisaged to operate with opensource software, enabling researchers to assemble and modify their microscopes with minimal challenges presented by proprietary (closed) hardware or software. Here, we describe the implementation of a low-cost, research-grade modular optical microscope applicable to research and pathology.

Keywords: Absorption spectra, aromatic compounds, charge transfer complexes, excitation energy, iodine.
Abstract: The formation of charge transfer (CT) complexes is effectively explained through stabilization of the highest occupied orbital of a donor molecule and destabilization of the lowest unoccupied orbital of an acceptor molecule in the molecular orbital diagram. Extensive density functional theory (DFT) calculations have been carried out to indicate the variation in structure, stability and charge transfer of CT complexes formed by homologous series of donors. The formation and structure of CT complexes of iodine with aromatic compounds are deduced. The excitation energy of CT complexes is also calculated by time-dependent DFT.

Subject: Marine spatial planning for a resilient and inclusive blue economy: Lakshadweep, India, a pilot study
Keywords: Blue economy, coastal zone management, marine spatial planning, sustainable development, seaweed cultivation.
Abstract: Ocean zoning through marine spatial planning (MSP) is an important component of the blue economy and has become an essential step towards realizing ecosystembased sea-use management. The concept was primarily initiated by the need to create marine protected areas, particularly in the European countries. An even more recent concern has focused on the need to conserve nature, especially ecologically and biologically sensitive areas in the context of multi-use planning of ocean space. To understand the value of MSP in India, a framework was created as part of the Indo-Norway International Ocean Management and Research Initiative. This study provides a framework for MSP in India for sustainable development in an ecologically sensitive area, namely the Lakshadweep group of islands on the west coast of the country. The findings of this study may serve as a reference for better management of maritime regions under various spatial jurisdictions.

Subject: Open sea cage culture of cobia: a catalyst for the blue economy along Indian coasts
Keywords: Blue economy, cobia, growth rate, mariculture, sea cages, wave height.
Abstract: The escalating global demand for fish protein necessitates the expansion of aquaculture from land to sea, facilitated by floating sea cages. In this study, the National Institute of Ocean Technology (NIOT), Chennai, Tamil nadu conducted a pilot-scale culture of hatchery-reared cobia seeds (Rachycentron canadum) in HDPE collar floating cages (9 m diameter with a cultivable volume of 320 m3 ). These cages were strategically deployed at Olaikuda (Gulf of Mannar, Tamil Nadu) and Thuplipalem (Andhra Pradesh), representing semi-protected (SP) and open sea (OS) environments respectively. The evaluation focused on growth performance, with cobia seeds stocked in cages at an initial biomass of 150 g/m3 (SP) and 154 g/m3 (OS), featuring an initial average weight of 32.49 ± 1.77 g and a total length of 15.6 ± 0.91 cm during stocking. In SP site, cobia exhibited significant growth, reaching an average weight of 3830 g in 270 days, with a specific growth rate (SGR) of 1.76% with a survival rate of 77%. In contrast, despite the longer culture period of 322 days at the OS site, lower average weight of 2550 g with an SGR of 1.35% with survival rate 62% at SP. Physicochemical and biological parameters at both sites remained within optimal ranges. Notably, the OS site experienced higher wave heights (ranging from 0.56 to 2.28 m); potentially impacting feeding patterns, high energy expenditure due to the exposed weather conditions resulted into reduced growth rate compared to the sheltered bay. This study aims to elucidate the comparative suitability of environmental settings and its economic feasibility for open sea cage farming

Subject: Harnessing the blue economy in Lakshadweep Islands through a sustainable tourism perspective
Keywords: Blue economy, community welfare, coral reefs, environmental management, sustainable tourism.
Abstract: This study delves into the dynamics of sustainable tourism in the Lakshadweep Archipelago, India, situated within the ambit of the blue economy framework. The study is centred around achieving a harmonious balance between economic growth and environmental conservation in the Lakshadweep Islands. It critically evaluates the tourism carrying capacity of the Islands, proposing a sustainable model that accommodates varying capacities, ranging from 12 beds in Chetlat to 434 beds in Kadmat, alongside a boating capacity of 207 in Bitra’s lagoon. A pivotal finding of this study is the urgent need for stringent environmental management measures, particularly focusing on the protection of fragile coral reef ecosystems against threats like plastic pollution. The limit of acceptable change is rigorously assessed, with coral reef health and water quality as crucial indicators. This study highlights the importance of implementing sustainable practices as a means to both safeguard the ecological integrity of Lakshadweep’s diverse islands and drive economic development. These findings play a crucial role in informing policy-making and guiding the alignment of tourism strategies in Lakshadweep with the overarching goals of environmental sustainability and enhancing community welfare.

Keywords: Blue economy, biodiversity, mariculture, marine bioprospecting, marine fisheries.
Abstract: India’s vast exclusive economic zone (EEZ) with its rich bounty of living and non-living resources, offers a great opportunity to expand its economy and food security, and could enable sustainable development and create resilient jobs. Marine fisheries, mariculture and marine bioprospecting are significant sectors which could act as the next big drivers of the GDP and public welfare. Marine biodiversity documentation sporadically requires innovative techniques using genomics in combination with underwater imagery to cover the full spectrum of marine living resources. Deep waters beyond 500 m depth are not optimally exploited and offer immense scope for commercial exploitation. The mariculture sector, despite the wide array of candidate species, is still in its infancy and requires the use of genetic engineering to develop breeds suitable for the mariculture systems. Employing new analytical technologies and a wide range of ‘multiomics’ tools can enhance the bioprospecting of numerous marine living resources, which have the potential to unravel hundreds of new compounds for human well-being. Ascertaining the continuity of the blue economy demands judicious management of oceanic resources through innovative and sustainable practices

Abstract: The interest in deep-sea mineral resources has surged recently, driven by the increasing need for metals and the global push for sustainable, low-carbon energy sources under the ‘blue economy’ framework. The deepsea minerals include polymetallic nodules, cobalt-rich Fe–Mn crusts, and polymetallic sulphides, which contain high amounts of copper, nickel, cobalt and other valuable metals. These mineral deposits are often associated with unique and fragile ecosystems, which necessitates the development of mining technologies with minimal environmental impact. Here, we review the key deep-sea minerals, their resource potential, exploration aspects and the need for sustainable extraction, with a particular focus on India’s exploration activities.

Subject: India’s blue economy priorities: maritime sector
Keywords: Blue economy, decarbonization, emission abatement, maritime policy, port modernization.
Abstract: Blue economy is an all-inclusive concept based on seas and shorelines. India has prioritized its blue economy policies, and maritime development (logistics, infrastructure and shipping) is one of them. For charting the nation’s growth, a regular review of global trends and India’s plans is imperative. The major drivers or focal areas will be decarbonization and digitalization. Increased costs due to transformations, including technology acceptances and investments in port development to improve productivity will be on predictable paths. Shipping route alternatives (Northern Sea route, Belt and Road Initiative, etc.) will be in the discourses. Digitalization measures such as Maritime Single Window, Port Community Systems, etc. will get traction. India needs to shift gears with its Sagarmala projects and keep pace with the global transformative changes, especially on the digital front. Based on its new National Logistics Policy, logistics costs as a large head need to be considered along with performance metrics. This article juxtaposes global trends and indices, and lists a few issues that India must address.

Subject: Propelling India’s blue economy: technological and governance perspectives in fisheries and aquaculture
Keywords: Blue economy, coastal aquaculture, fisheries, governance perspective, sustainable development, technological advancements.
Abstract: The blue economy, encompassing sustainable utilization of coastal and oceanic resources, has gained global significance in the context of the developing discourse on economic growth and environmental conservation in ocean-based economies. This article delves into the multifaceted realm of India’s fisheries and coastal aquaculture sectors, exploring their status, challenges and prospects through the lens of the ‘blue growth’ narrative. Various enabling factors, such as technological advancements, governance improvements, market and policy incentives, and investment strategies are discussed that can catalyse a smooth transition of India’s marine capture fisheries and aquaculture to align with the blue developmental agenda.

Subject: Prospects of the blue economy in India: emerging policy challenges and the way forward
Keywords: Blue trade, development strategies, economic growth, environmental sustainability, marine serv
Abstract: ‘Blue economy’ is becoming a buzzword for high economic growth with environmental sustainability, which is a reflection of the experiences of both developed and developing countries. A growing ‘blue voice’ emanates from a wide spectrum of countries about the efficacy of development strategies. Empirical evidence indicates that there is no ‘stylized fact’ about the contribution of blue economy to a country’s GDP. As a satellite account, the blue economy contributed 4.1% of India’s GDP in 2016. Accounting of the sector is important to identify priority sectors for policy planning in areas such as investment, employment, technology and other aspects of financial decisions. The blue economy value added in India is not only growing faster than the overall GDP, but is also becoming resilient to withstand adverse effects of the global exogenous shocks. Blue trade is becoming robust and is growing faster than the overall trade of a large number of littoral states. In India, blue trade shared more than 10% of the overall trade and openness of the sector was more than 100% during 2011–16. In blue trade, merchandise and services trade registered a favourable trade balance during 2008–22. The blue economy is likely to drive the Indian economy on a high-growth path after effective implementation of the National Blue Economy Advisory Council.
