This book addresses strategies for mitigating and adapting to climate change in natural systems. According to the IPCC (2021) report, human-induced climate change has widespread global effects, significantly impacting natural ecosystems. Extreme weather events linked to climate change harm terrestrial, freshwater, ocean, and coastal ecosystems, reduce food security, displace populations, damage livelihoods, health, and security, and exacerbate inequality. While the impacts of climate change are vast and varied, making it impossible to cover every sector, the authors have aimed to address key areas and offer strategies for combating climate change through mitigation and adaptation. The book is structured into five sections: • Land (agriculture, horticulture, soil, forest) • Water (rivers, lakes) • Atmosphere (hydrology, climate) • Technologies/Approaches (remote sensing, GIS, AI tools, ChatGPT) • Case Studies (crops, forests, soil glomalin application, eco-friendly fertilizers), with a focus on modelling approaches to assess these strategies. Additionally, the authors reviewed related works on climate change mitigation and adaptation, identifying a gap in using newer technologies and approaches. The book also covers topics such as water quality and the analysis of several greenhouse gases such ad NO2, O3, CO2 and CH4 in the environment. This book will be beneficial for students, educators, professionals, researchers, policymakers, and farmers. It provides content ranging from introductory to advanced levels, making it accessible to those working in environmental science.
