    Dynamic land use and coastline changes in active estuarine regions - A study of sundarban delta
    (International Society for Photogrammetry and Remote Sensing, 2014) Thomas, J.V.; Arunachalam, A.; Jaiswal, R.; Diwakar, P.G.; Kiran, B.
    Alteration of natural environment in the wake of global warming is one of the most serious issues, which is being discussed across the world. Over the last 100 years, global sea level rose by 1.0-2.5 mm/y. Present estimates of future sea-level rise induced by climate change range from 28 to 98 cm for the year 2100. It has been estimated that a 1-m rise in sea-level could displace nearly 7 million people from their homes in India. The climate change and associated sea level rise is proclaimed to be a serious threat especially to the low lying coastal areas. Thus, study of long term effects on an estuarine region not only gives opportunity for identifying the vulnerable areas but also gives a clue to the periods where the sea level rise was significant and verifies climate change impact on sea level rise. Multi-temporal remote sensing data and GIS tools are often used to study the pattern of erosion/ accretion in an area and to predict the future coast lines. The present study has been carried out in the Indian Sundarbans area. Major land cover/ land use classes has been delineated and change analysis of the land cover/ land use feature was performed using multi-temporal satellite images (Landsat MSS, TM, ETM+) from 1973 to 2010. Multivariate GIS based analysis was carried out to depict vulnerability and its trend, spatially. Digital Shoreline change analysis also was attempted for two islands, namely, Ghoramara and Sagar Islands using the past 40 years of satellite data and validated with 2012 Resourcesat-2 LISS III data.

    Climate Change and COVID-19 Metaphors: Environmental Consciousness in Social Media
    (Institute of Electrical and Electronics Engineers Inc., 2021) Chetty, N.; Alathur, S.
    The changes in environmental conditions have reportable impacts on the Covid-19 pandemic and vice versa. About these impacts, the people are deliberating metaphorically on climate change and Covid-19. The purpose of the paper is to analyze and identify the people's consciousness about the interrelationship between climate change and Covid-19. The existing literature on climate change and impacts on Covid-19 are reviewed, and inferences have been drawn from the result. Apart from the literature review, the Twitter social media content is analyzed and interpreted. The results have shown that there are noticeable impacts of climate change on Covid-19 and vice-versa. The people are conscious of the relationship between climate change and the Covid-19 pandemic. © 2021 IEEE.

    Climate Change and Water Security—An Introduction
    (Springer Science and Business Media Deutschland GmbH, 2022) Natarajan, S.; Mondal, A.; Kolathayar, S.
    This chapter presents basic concepts related to climate change and water security. Further, the chapter introduces the book volume on Climate Change and Water Security that includes various relevant topics for assessment of water quantity and quality in a changing environment, disaster risk, their possible future prognosis, as well as adaptation and protection measures. The focus is primarily on low-income countries such as India, Ethiopia, and Bangladesh, that may be particularly vulnerable to the adverse effects of climate change. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    A Review of the Green Climate Fund and Its Implications on Sustainable Development Goals for Developing Countries
    (Springer Science and Business Media Deutschland GmbH, 2025) Datta, K.; Jena, P.R.
    The Green Climate Fund (GCF), established within the United Nations Framework Convention on Climate Change (UNFCC), is a pivotal force in addressing climate change mitigation and adaptation. As climate change worsens into a worldwide disaster, the need to address its consequences gets more urgent. In response, the GCF emerges, as one of the primary climate finance mechanisms, providing a solid platform for mobilizing climate finance and facilitating transformative projects in developing nations to help them address climate-related concerns. Our systematic literature review rigorously examines the GCF’s global impact by delving into its organizational structure, funding mechanisms, and project efficacy. Employing the PRISMA methodology, we meticulously evaluate 39 peer-reviewed articles from Scopus. This review enriches the understanding of the GCF’s central role in global climate finance and sustainability, its contributions, and the challenges it faces. Our analysis reveals that the GCF demonstrates potential in balancing mitigation and adaptation through innovative approaches, including private sector engagement and equitable fund distribution. However, issues persist regarding adaptation finance accessibility for vulnerable states. To enhance effectiveness, we advocate for increased investment in decentralized, community-led solutions aligned with long-term development goals. A probable shortfall in meeting mitigation targets outlined in the Copenhagen Agreements, emphasizing the urgent need for increased financial resources. Diversifying funding sources and improving transparency are crucial for effective climate financing. This study provides vital insights to guide the GCF’s evolution and improve its efficacy in addressing climate change while advancing sustainable development globally. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
