    Scientific Mapping of Gender in Sustainable Tourism Research: A Bibliometric Approach
    (Emerald Publishing, 2025) Talawar, A.; Sheena, S.
    The intersection of gender and sustainability in tourism research has gained significant attention across academic research and policymaking, focusing on Sustainable Development Goals (SDGs) that are closely aligned with the United Nations SDGs, particularly gender equality (SDG 5) and responsible consumption and production (SDG 12). Gender plays an important role in driving sustainable transformation in the tourism sector, influencing cultural and environmental conservation and socioeconomic aspects. This chapter discusses a bibliometric analysis of articles focusing on gender and sustain-ability in tourism research to elucidate publication trends, identify influential journals and prominent authors, and uncover key research themes and emerging hotspots of research trends. The Bibliometrix R package was employed to analyze 438 research articles selected from the Scopus database between the period 2015 and 2024. The findings indicated an increasing trend in publications, with a wide distribution of publications across numerous journals. Further, the Journal of Sustainable Tourism was the most influen-tial, and countries like Spain, China, and the United States have made noteworthy contributions in the area. India ranks the highest in single-country publications (SCP), indicating a notable emphasis on region-specific research. Meanwhile, the United States and China lead in the multiple-country publications (MCP), indicating higher international collaborative research efforts. Furthermore, the findings emphasize that gender-inclusive policies are essential to fostering innovation, advancing leadership roles, and promoting corporate sustainability and entrepreneur-ship within the tourism sector. Finally, gender-specific strategies are imper-ative for achieving sustainable transport and driving socioeconomic transformation, highlighting the need for tailored gender-sensitive strategies for sustainable tourism development. © 2026 Dhishna Pannikot.

    Does Board Gender Diversity Enhance the Sustainable Performance of Firms? Empirical Evidence From India
    (Emerald Publishing, 2025) Poornima, S.; Gopalakrishna, B.V.; Samanta, M.
    This study explores the link between board gender diversity and corporate sustainability disclosure. The study employs 417 Indian companies to investigate how the incorporation of corporate sustainability disclosure and gender diversity on the board of directors interrelate. The findings show that companies with a higher proportion of female directors enhance sustainable disclosure by taking favorable reporting measures to address environmental issues, social welfare concerns, and governance problems. The companies with more women on board incorporate highly sensitive initiatives regarding the environment, society, and overall governance. These results suggest that women directors add valuable diversity, leading to better decisions and a stronger focus on social and environmental concerns. This study extends the prevailing literature on gender studies and sustainability by presenting empirical recommendations about the role of females in corporate decision-making, specifically related to the sustainability of Indian firms. © 2026 Dhishna Pannikot.

    Retailing and pricing decisions in a three-tier fabless semiconductor supply chain with stochastic consumption rate and channel power structures under sustainability measures
    (Taylor and Francis Ltd., 2024) Raju, S.; Tm, R.; Kumar, S.P.; Taleizadeh, A.A.
    This study investigates the trade-off between sustainability measures and pricing strategies within a three-tier fabless semiconductor supply chain. We examine diverse configurations of channel power to identify the optimal power structure when integrating sustainability measures into the semiconductor foundry. The Stackelberg game, Vertical Nash game, and Mean-Variance analysis are employed to model the complex dynamics among channel partners. The findings indicate that for a specific threshold limit of manufacturing and sustainability costs, implementing sustainability measures not only increases the optimal price for foundry but also enhances the margin and sales volume for the fabless company, leading to improved profits for all chain partners. Examining channel power structures reveals the threshold limit of sustainability cost which maximise the profit for the channel leader and the channel follower. Additionally, lower price elasticity favours maximum profits under channel leadership, whereas higher price elasticity values result in higher optimal profits when both partners share comparable channel power. The study also identifies the significant influence of partners’ risk aversion on overall profitability and offers valuable insights for practicing managers in the fabless supply chain, providing guidance on optimising pricing strategies, navigating channel power dynamics, considering price elasticity, and managing risk aversion to enhance overall profitability. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

    Impact assessment of watershed development programme - A case study of Itagi watershed
    (2010) Palakshappa, K.; Nagaraj, M.K.; Shivapur, A.V.
    Soil, water and vegetation are the important gifts of nature to mankind. Welfare and development of mankind and its civilization revolves around conservation and development of these vital natural resources, which are so interdependent that one can not be managed efficiently without the other two. Watershed Development Programs (WDP) going on in India basically as soil and water conservative programs (as a policy response to the increasing environmental crisis and non-sustainability of agriculture especially in the dry land/semi-arid regions) has modified substantially with the introduction of watershed guidelines in 1994 by the Government of India. In the present study the area considered for assessment is Itagi sub watershed in Ranebennur taluk, Haveri district, Karnataka. During the watershed development programme soil and water conservation structures were constructed in the study area in the year 2004. The analysis of data reveals that there is an improvement in the groundwater recharge, increase in yield of the wells, increase in agricultural production, reduction in soil erosion and many other tangible and intangible benefits as a result of this watershed development programme. © 2010 CAFET-INNOVA TECHNICAL SOCIETY.

    Use of Laterite as a sustainable building material in developing countries
    (CAFET INNOVA Technical Society cafetinnova@gmail.com 1-2-18/103, Mohini Mansion, Gagan Mahal Road, Domalguda, Hyderabad 500029, 2014) Kasthurba, A.K.; Reddy, K.R.; Venkat Reddy, D.V.
    Utilisation of local materials is an important step to sustainable construction to reduce transportation cost, save embodied energy, and protect the environment. This paper advocates the use of local laterite-a soil type rich in iron and alumina formed under hot and wet tropical conditions-due to its cost effectiveness and energy efficiency than that of conventional modern materials in tropical developing countries. This paper summarizes the occurrence and characteristics of laterite and then highlights the need for developing universal database of properties and standard testing protocols to facilitate evaluation and extensive use laterite in building applications. Understanding of properties and potential challenges of using this material will benefit for the development of suitable strategies/techniques for sustainable construction. Overall, this study identifies various factors that should be considered for efficient utilization and managements of laterite in construction to meet the growing demand of new housing and infrastructural in different regions of developing tropical world. © 2014 CAFET-INNOVA TECHNICAL SOCIETY.

    Groundwater sustainability assessment in coastal aquifers
    (Indian Academy of Sciences, 2016) Lathashri, U.A.; Mahesha, A.
    The present work investigates the response of shallow, coastal unconfined aquifers to anticipated overdraft conditions and climate change effect using numerical simulation. The groundwater flow model MODFLOW and variable density groundwater model SEAWAT are used for this investigation. The transmissivity and specific yield estimated from the existing database range from 10 to 810 m2/day and 0.08% to 10.92% respectively. After successful calibration with Nash-Sutcliffe efficiency greater than 0.80, the values of horizontal hydraulic conductivity and specific yield of the unconfined aquifer were set in the range 1.85-61.90 m/day and 0.006-0.24 respectively. After validating the model, it is applied for forecasting the aquifer’s response to anticipated future scenarios of groundwater draft, recharge rate and sea level rise. The findings of the study illustrate that saltwater intrusion is intensified in the area adjoining the tidal rivers, rather than that due to the sea alone. Of all the scenarios simulated, the immense negative impact on groundwater quality emerges due to overdraft conditions and reduced recharge with the areal extent of seawater intrusion exceeding about 67% (TDS>1 kg/m3). The study also arrives at the conclusion that, regional sea level rise of 1 mm/year has no impact on the groundwater dynamics of the aquifer. © Indian Academy of Sciences.

    An Integrated Geohydrology and Geomorphology Based Subsurface Solid Modelling for Site Suitability of Artificial Groundwater Recharge: Bhalki Micro-watershed, Karnataka
    (Springer, 2020) Saicharan, V.S.; Naga Jyothi, B.; Saha, R.; Wankhede, T.; Das, I.C.; Venkatesh, J.
    The groundwater resources of basaltic terrains in peninsular India are decreasing rapidly, due to indiscriminate extraction without considering the recharge capabilities of an aquifer. The main focus of the present study is to develop a good perceptive of the groundwater recharge capabilities in basaltic terrains for long term groundwater sustainability. In the present study 3D aquifer solid model of the sub-surface was integrated with surface variables like geomorphology, lineament density, drainage density, slope, land use along with lithology and soil, derived from earth observation (EO) data. This gives a robust platform to find the complex geology of the study area for facilitating artificial groundwater recharge. The methodology adopted provides an opportunity to integrate all the groundwater-related data for a better understanding of the groundwater and surface water interplay in terms of recharge phenomena. The research signified three categories of recharge zones ‘highly-suitable’; ‘moderately-suitable’; and ‘unsuitable’. The recharge zones are found to be in accord with the observed pre and post-monsoon groundwater table signifying the validity of the model. This study would be helpful to delineate groundwater recharge plan in similar geological provinces for ensuring the balance of groundwater resources. © 2020, GEOL. SOC. INDIA.

    Studies on application of vertical axis hydro turbine for sustainable power generation in irrigation channels with different bed slopes
    (Elsevier Ltd, 2021) Shashikumar, S.; Honnasiddaiah, R.; Hindasageri, V.; Madav, V.
    The present work is carried out to study the performance of a Savonius rotor for small-scale hydropower generation. It has been observed that some of the irrigation channels available in the rural areas are having enough bed slope to generate kinetic energy, which can be harnessed through a Savonius rotor. An in-house fabricated scale-down model of the Savonius rotor is tested at an inclination of the re-circulating indoor multipurpose tilting flume at 0°, 0.5°, 1.0°, 1.5° and 2.0° to determine performance under controlled conditions. It is observed that at the tip speed ratio of 0.92 and channel inclination of 0.5° compared to 0° inclination, the coefficient of power and coefficient of torque improved to 40% and 10%, respectively. Furthermore, it is found that the torque and power developed by the turbine are maximum at a bed slope of 2.0° owing to the maximum available energy. © 2020 Elsevier Ltd

    Impact of COVID-19 on the Indian seaport transportation and maritime supply chain
    (Elsevier Ltd, 2021) Narasimha, P.T.; Jena, P.R.; Majhi, R.
    Impacts of COVID-19 in maritime transportation and its related policy measures have been investigated by more and more organizations and researchers across the world. This paper aims to examine the impacts of COVID-19 on seaport transportation and the maritime supply chain field and its related issues in India. Secondary data are used to analyze the performance indicators of major seaports in India before and during the COVID-19 crisis. We further explore and discuss the expert's views about the impact, preparedness, response, and recovery aspects for the maritime-related sector in India. The results on the quantitative performance of Indian major seaports during the COVID-19 indicate a negative growth in the cargo traffic and a decrease in the number of vessel traffic compared to pre-COVID-19. The expert survey results suggest a lack of preparedness for COVID-19 and the need for developing future strategies by maritime organizations. The overall findings of the study shall assist in formulating maritime strategies by enhancing supply chain resilience and sustainable business recovery process while preparing for a post-COVID-19 crisis. The study also notes that the Covid-19 crisis is still an ongoing concern, as the government, maritime organizations, and stakeholders face towards providing vaccine and remedial treatment to infected people. Further, this study can be expanded to the global maritime supply chain business context and to conduct interdisciplinary research in marine technical fields and maritime environment to measure the impact of COVID-19. © 2021 Elsevier Ltd
