A Bibliometric Exploration of Sustainability Reporting: Themes, Evolution and Future Direction
(SAGE Publications Ltd, 2025) Himanshi Tolani; Jagriti Gupta; Akhil Mishra
The inclusion of non-financial information in corporate reports marks a significant advancement in business communication. It enhances corporate participation and transparency through sustainability reporting in environmental, social, economic and governance aspects. This study adopts a hybrid approach, combining bibliometric analysis and a systematic literature review of the most influential works on sustainability reporting from 2015 to 2024. Using the PRISMA protocol, 122 articles from the Scopus database were analysed. Key findings reveal publication patterns, the most cited countries and articles, as well as the most influential affiliations and keywords, which indicate the main drivers of sustainability reporting practices. The study also applies the Theory, Context and Methodology framework by integrating stakeholder, institutional and legitimacy theories to provide a comprehensive understanding of sustainability reporting. The findings show a notable increase in research activity since 2018, with major contributions from Italy, Spain and Australia. Sixty per cent of the studies adopt qualitative research methods and focus on emerging themes such as the alignment of sustainability reporting with financial performance, environmental sustainability, and technological advancements. These studies provide valuable theoretical insights that help lay the foundation for the further development of sustainability reporting. This research offers policymakers, governments and academic partners actionable insights, a framework for addressing research gaps, and strategies for advancing sustainability reporting practices. © 2025 Institute of Public Enterprise
Does the Laxmi Ridge continue towards the Laccadive Ridge? New insights from an integrated geophysical study
(Elsevier Ltd, 2020) Akhil Mishra; Anil Kumar Chaubey; Shravan Kumar; Pitchika Vinay Kumar; Pankaj Kumar; Kanchan Mani Dubey
The Laxmi and Laccadive ridges are two major aseismic ridges in the NW Indian Ocean. Bathymetry, gravity and magnetic data and their derivatives are analyzed and modelled to assess interrelationship between both the ridges as well as to establish their crustal structure, nature and isostatic compensation. Boundaries of the Laxmi and Laccadive ridges are delineated by tilt derivative with constraints from available seismic-sections. Integrated gravity and magnetic models reveal that both the ridges have almost similar crustal layers and are underplated all along its length. Crustal models also depict that both the ridges are carpeted with flood basalt and heavily intruded. 3D coherence between mantle Bouguer anomaly and residual bathymetry reveals that the elastic plate thickness and subsurface to surface load ratio for both the ridges vary from 3 to 4 km and 0.7 to 0.8, respectively. Several characteristic similarities viz. crustal structure and nature, elastic plate thickness, magmatism have been observed for both the ridges. Seismic sections near the junction of the ridges suggest that the basement high corresponding to the Laxmi Ridge is further continued towards the Laccadive Ridge. In addition, the northwestern part of the Laccadive Ridge has NW-SE structural lineaments similar to that of the NW-SE segment of the Laxmi Ridge. Based on results of the present and previous studies, we infer that (i) the Laxmi Ridge is extended southeastward towards the Laccadive Ridge, (ii) both the ridges are continental slivers which are underplated as well as intruded and carpeted by volcanics, and (iii) both the ridges are locally compensated. © 2020 Elsevier Ltd
Geopotential imprints on the tectono-thermal evolution of the northwest Indian Ocean
(Springer Science and Business Media B.V., 2025) Shravan Prasanna Kumar; Korimilli Naga Durga Prasad; Akhil Mishra; A. Akilbasha
The study investigates the tectonic and lithospheric characteristics of the northwestern Indian Ocean, emphasizing tectonothermal parameters: Moho depth, Effective Elastic Thickness (Te), loading ratio (F), Depth to the Bottom of the Magnetic Sources (DBMS), and Geoid-to-Topography Ratio (GTR). Low to moderate Te values, moderate to high F values and low to moderate DBMS over aseismic ridges, such as the Laxmi and Laccadive Ridges, suggest dominant subsurface loading due to underplating and mantle magma intrusion. The Murray Ridge exhibits the DBMS close to the Moho, indicating a relatively warm lithosphere. The Carlsberg Ridge, as expected, shows a thin oceanic crust (~ 8 km Moho depth) and significant variations in Te and DBMS along its length. These reflect mantle upwelling, magmatic processes, and lithospheric stretching. Seamounts in the Arabian Basin likely formed due to ridge spreading and volcanic activity near the Carlsberg Ridge. The seamount chain in the East Somali Basin may have formed from magma rising beneath the moving African plate. The Chain Ridge separates oceanic lithospheres of varying ages, showing strong lithospheric support with localized thermal modifications and high GTR. Variations in GTR values depict compensation mechanisms, transitioning from shallow in the younger crust (< 30 Ma) to deeper in the older crust, driven by mantle dynamics and lithospheric processes. The relationship between crustal age and DBMS reveals two tectono-thermal events: one at 35 Ma, which may be associated with Indian-Eurasian collision processes; the other at 65 Ma, is related to Réunion hotspot activity formed that caused Deccan volcanism and underplating in the adjacent region. © The Author(s), under exclusive licence to Springer Nature B.V. 2025.
