Item Invasion of Humans into Ecology: Studying Urban Patterns and Ecological Functions for Resilient Ecosystems(Springer, Singapore, 2025) Ambrina Sardar Khan , Prateek SrivastavaUrban ecosystems are in constant flux driven by intricate interactions between socioeconomic dynamics and biophysical processes that occur at different locations and over varying periods. The central theoretical framework for urban ecology posits that cities are emergent entities shaped by the localized interactions between humans and natural systems. Urbanization presents substantial challenges to ecological integrity, resulting in altered biodiversity, compromised ecosystem functions, and reduced resilience. This chapter aims to investigate the patterns of human encroachment into natural habitats and their consequent impact on ecological functions, with a focus on developing strategies for resilient urban ecosystems. Using a multidisciplinary approach that integrates landscape ecology, urban planning, and environmental science, we analysed global and regional urbanization trends and their ecological consequences. Our findings indicate that urbanization leads to habitat fragmentation, biotic homogenization, and a decline in environmental and ecological services such as carbon (C) sequestration, water regulation, and soil health. To mitigate these challenges, we propose a series of strategies to enhance urban ecosystem resilience, including implementation of green infrastructure, sustainable urban planning policies, and active community involvement. This chapter underscores the importance of collaborative efforts between scientists, urban planners, policymakers, and the public in fostering resilient urban ecosystems capable of withstanding the pressures of urbanization and climate change.Item Innovations and Advancement in Climate Science: Mechanistic Approaches and Computational Modelling(Springer, Singapore, 2025) Ambrina Sardar Khan , Prateek SrivastavaGiven the essential role of climate models in understanding and forecasting the risks associated with climate change, an in-depth exploration of meteorological science provides a necessary foundation for appreciating the complexity and utility of these models. They offer the foundation for anticipating consequences, guiding adaptation measures, and establishing mitigation objectives. As society faces the urgent challenges posed by rapidly escalating climate change, there is an increasing demand for detailed and precise information to support robust decision making and achieve the goal of net zero emissions by 2050. Leveraging existing technological advancements and scientific capacities requires more international cooperation and investment in next-generation supercomputing and earth system science. This groundbreaking strategy has the potential to produce substantial scientific insights required to increase ambitions in both mitigation and adaptation activities over the next few decades. By encouraging collaboration and enhancing climate modelling, we can better navigate the complexities of climate change and work towards a sustainable future.Item Bridging the Gap Between Environmental Justice and Ecosystem Management: A Comprehensive Framework for Equitable Sustainability(Springer, Singapore, 2025) Ambrina Sardar Khan , Prateek SrivastavaEnvironmental justice (EJ) emphasizes the fair distribution of environmental benefits and burdens, ensuring that all individuals, regardless of race, income, or social status, have access to clean air, water, or other natural resources. This concept is critical for ecosystem management (EM), a framework focused on sustaining ecosystem health while balancing human and ecological needs. Disproportionate environmental impacts often burden marginalized communities, which are more vulnerable to pollution and resource depletion owing to industrial activities, land degradation, and biodiversity loss. Environmental justice in ecosystem management emphasizes equitable access to natural resources and healthy environments for all individuals and communities. This concept integrates the principles of fairness, equity, and sustainability into the distribution of environmental benefits and burdens. The ecosystem approach, which has emerged in international environmental policy, shares synergies with environmental justice principles. It promotes mechanisms such as equitable benefit-sharing, conservation and sustainable use, adaptive management, and participatory practices. This approach addresses various dimensions of justice including distributional fairness, democratic choices, place specificity, and spatial equity. Environmental justice extends beyond human-centric concerns to include ecological justice, which considers the rights of nonhuman species and biospheric egalitarianism. This broader perspective challenges traditional notions of justice and calls for a more inclusive approach to ecosystem management. In practice, implementing environmental justice in ecosystem management is challenging. For instance, in Indonesia and Uzbekistan, despite legal mandates, environmental justice regulations have led to social and environmental conflict. Similarly, global disparities in exposure to environmental risks and benefits persist between developed and developing countries. To address these challenges, a comprehensive framework of environmental justice in ecosystem management is required. Collaborative governance models, adaptive management practices, incorporate distributive justice, procedural justice, justice-as-recognition, intergenerational equity, precautionary principle and recognition of traditional ecological knowledge are key to bridging the gap between EJ and EM, ensuring that all stakeholders have a voice in maintaining healthy ecosystems.Item Integrating Environmental Monitoring Techniques for an Effective Healthcare System(CRC Press, 2023) Nupur Joshi, Ambrina Sardar KhanHealth is not merely the absence of disease but a state of complete physical, social, and mental activeness, whereas health care is the management, treatment, and prevention of illness. Health is a very important parameter to indicate the good living and quality of life of an individual. Many pathological factors are involved in a disease such as people, vectors, causative agents, and hosts. Monitoring of health and development of the public health sector is an important aspect for the social, cultural, and economic well-being of society. Thus, for the analysis of these pathological factors with their relationship with geographical distribution, GIS (spatial, temporal references) and other cartographic information taken from remote sensing and other technologies can be used effectively. Through mapping and analysed temporal and spatial patterns, the distribution of a particular health status cause can be tracked. Incorporating the records attained from ground data and sensors helps in the enhancement of results. This review includes recent literature on healthcare and GIS. It includes descriptions of various disease agents, and how GIS helps in the analysis of their distribution and occurrence. To study a disease, GIS is a promising area however it has not reached its full potential. For this, disease and environmental observation systems need to be further developed.Item Anatomisation of Land Use/Land Cover (LULC) Dynamics with a Focus on Land Surface Temperature in Lucknow City Using Geospatial Techniques(CRC Press, 2023) Akanksha, Pranjal Pandey, Ambrina Sardar KhanRapid augmentation in urban areas throughout the world has become an inescapable phenomenon. As the population continues to grow, the geological boundaries are extending too. This study focuses completely on improvements in urbanised urban communities and their development with the assistance of spatial variation utilising time-series satellite data and statistically generated models to observe the pattern of LULC transition over the last 19 years of one of the most expeditiously urbanising cities of India: Lucknow. The classification report indicated an expansion of 96.51 sq. km of built-up area and shrinkage in covers of agricultural land and vegetation spread. To gauge the changing spatial patterns in urban expansion, the Shannon Entropy Index technique is applied over the chosen time frame dependent on LULC change and a statistical approach. The perception we got from this study depends on classification and statistically created models of satellite data. The land surface temperature (LST) is additionally depicted to discover the impacts of urban sprawl on nearby temperatures. General increases of 3.26℃ and 2.01℃ were seen in the minimum and maximum temperature, respectively, from 2000 to 2019. LST is also correlated with the vegetation index (NDVI), built-up index (NDBI), and water index (MNDWI). The total increase of the population and an unsustainable expansion rate of urban sprawl in the study area illustrates the elevation in LST.Item Terrestrial Diatoms and Their Potential for Ecological Monitoring(Springer, Singapore, 2025) Saleha Naz, Sarika Grover, Ambrina Sardar Khan, Jyoti Verma, Prateek SrivastavaDiatoms have long been utilized as robust ecological indicators for aquatic ecosystems. Ecological data of aquatic diatoms have been well documented. Autecological and biotic indices have extensively used for ecoassessment of water bodies throughout the world. In spite of the fact that diatoms are quite abundant in terrestrial environments and respond quickly to soil environment fluctuations, ecological studies on these entities are substantially lacking as compared to their aquatic counterparts. Of late researchers have investigated certain aspects of soil diatom ecology from some parts of the world. Terrestrial diatoms have been found to be quite responsive to soil environmental conditions, anthropogenic disturbances and agricultural practices. This review attempts to assemble the diverse findings associated with the terrestrial diatoms and their response towards various stressors and explores the future prospects of soil diatom ecology.Item Biofuels from Diatoms: Potential and Challenges(Springer, Singapore, 2025) Jyoti Verma, Akriti, Hemlata Pant, Ambrina Sardar KhanBiofuel is the hope of this planet to ensure safe and sustainable use amid increasing rate of pollution and global warming. The term biofuel may be misleading for some that it is only substitute of fossil fuels, which is not true. Biofuel is a broad term including bio-oil, biodiesel, bioethanol, biogas, etc. finding its use in transportation, cosmetics, cooking, nutrient supplements, etc. The generation of biofuel from diatoms is third-generation biofuel production. Either the lipid from diatoms is extracted as bio-oil or the whole biomass of diatoms is used as biocrude. Apart from the mainstream uses of biofuel, the diatom culture produces many by-products which find their use in multiple fields. The public authority of India reported Biofuels Policy in 2008 to advance its production and utilization. The main obstacle on the way is economic production of biofuel from diatoms, to make it worth choosing over other options. Diatoms grow fast but they produce lipids slow, and the process of extraction is even more tedious. However, with the use of recent technologies, proper management and planning, this method proves to be the most efficient and environment friendly way of biofuel production. Diatoms don’t have a large number of cells in the body to support, they use carbon dioxide and other nutrients from waste, or eutrophied water bodies produce biofuel and clean their nearby environment in return. It is high time we develop this method to make it feasible for greater good.Item Gut Microbiota and Colorectal Cancer Pathogenesis(Humana, Cham, 2025) Anas Islam, Badruddeen, Mohammad Irfan Khan, Mohsin Vahid Khan, Yusuf AsadThis chapter explores the complex relationship between the gut microbiota and the pathogenesis of colorectal cancer (CRC), highlighting the role of microbial dysbiosis in promoting inflammation, DNA damage, and immune dysregulation. It reviews key pro-carcinogenic bacteria, such as Fusobacterium nucleatum, Bacteroides fragilis, and pks+ Escherichia coli, which contribute to tumor initiation and progression. The chapter also discusses the protective effects of beneficial microbes like Lactobacillus and Bifidobacterium, which help maintain gut health and inhibit carcinogenesis. Therapeutic strategies aimed at modulating the gut microbiota, including dietary interventions, probiotics, prebiotics, fecal microbiota transplantation (FMT), and postbiotics, are examined for their potential in CRC prevention and treatment. Finally, future directions in personalized microbiome-based therapies, diagnostic biomarkers, and the challenges facing clinical translation of gut microbiota research are addressed. The chapter emphasizes the growing importance of targeting the microbiome in CRC management to enhance prevention, diagnosis, and therapeutic outcomes.Item Micro-nano Plastics: Impact on Gastrointestinal System(Springer, Singapore, 2025) Shareen Fatima Rizvi, Syed Khalida Izhar, Uzma Afaq, Mohammed Kuddus, Danish Iqbal, RoohiAside from the numerous technological advantages of living in the “plastic age,” the sheer abundance of plastic products, their unsustainable use and disposal, and their great durability in the environment all contribute to pollution dangers, raising significant environmental and public health concerns (Fackelmann and Sommer 2019). Growing concerns have been raised that waste management needs to be equipped to deal with the vast quantities of plastics being produced and disposed of via the several available channels (Rajpal et al. 2024). Microplastics (MPs) are tiny fragments of plastic released into the environment when consumer or industrial plastic goods are discarded or degraded. Microplastics are categorized based on their origin into two distinct groups. The first ones are primary microplastics. These are manufactured in shapes such as pellets, nurdles, and microfibers for cosmetics, toothpaste, pharmaceutical drugs, and textiles. Secondary microplastics are the second category of microplastics. These originate when larger plastic materials are fragmented into tinier pieces in nature (Weber et al. 2022).Item Implications of Polyextremophiles in Astrobiology Research(Springer, Cham, 2025) Gaurav Yadav, Sahaj Bharindwal, Anchal Mehrotra, Surati Kumari, Roohi, Renitta JobbyAstrobiology seeks to expand our knowledge of life by investigating how microorganisms survive and thrive in extreme environments, allowing us to better assess the potential habitability of distant worlds. Recent developments in the study of extremophiles, solar system planetary exploration, and exoplanet discovery and analysis are providing fresh insights into astrobiology and the possible distribution of life on other planets. Extraterrestrial environments frequently feature extreme conditions spanning multiple factors simultaneously. In order to survive in such complex and extreme conditions organisms need to develop adaptations that enable them to withstand a wide range of challenges. Therefore, a critical next step toward understanding the true limits of habitability is the study of polyextremophiles, or microorganisms that can survive under multiple extreme conditions simultaneously. This chapter outlines various extreme environments on Earth and the types of extremophiles found in these conditions. This chapter also explores the interesting world of polyextremophiles and the strategies they have evolved that enable them to thrive in these environments. Polyextremophiles can serve as invaluable model organisms in astrobiology, offering insights into the possibilities of life beyond Earth and to gain valuable knowledge for future space exploration missions.
