The intricate interplay between food, energy, water, societal dynamics, and the environment constitutes the bedrock of contemporary global challenges. In recent decades, this convergence has emerged as a focal point for scientific inquiry, policy formulation, and societal discourse. This book seeks to meticulously unravel the complexities inherent in this nexus, shedding profound light on the interconnected risks, vulnerabilities, and transformative opportunities that define our quest for sustainability in the twenty-first century. The materials of this book were prepared mainly by authors working on the joint project between the International Institute for Applied Systems Analysis (IIASA) and the National Academy of Sciences (NAS) of Ukraine “Integrated robust modeling and management of food-energy-water-land use nexus for sustainable development”, and on the project “Comprehensive analysis of robust preventive and adaptive measures of food, energy, water, and social management in the context of systemic risks and consequences of COVID-19” (0122U000552) of the NAS of Ukraine. Members of the System Analysis Committee of the NAS of Ukraine were also involved in the preparation of book chapters. The authors dedicate this book to the memory of the Academician of NAS of Ukraine, Professor Yuri Ermoliev, who died in October 2022 and made a fundamental contribution to stochastic optimization as a basic tool for quantitative risk management. This book largely follows his ideas about risk management and its applications.

This book emphasizes the need for harmonized policies and adaptive strategies that can address the complexities of local, national, and global systems simultaneously. The interconnected challenges of our time—climate change, resource depletion, systemic risks, and socio-economic inequalities —demand a multidisciplinary and integrated approach to sustainable development. This second volume, Nexus of Sustainability: Understanding of FEWSE Systems II, builds upon the foundations laid in the first volume, deepening our exploration of the complex interplay among Food, Energy, Water, Social, and Environmental (FEWSE) systems. It highlights both the vulnerabilities within these systems and the transformative opportunities that arise when they are considered as interconnected components of a greater whole. This book comes at a pivotal moment in global sustainability discourse. Building on the outcomes of the Joint Research Project between the National Academy of Sciences of Ukraine (NASU) and the International Institute for Applied Systems Analysis (IIASA), this book synthesizes advanced systems analysis, innovative modeling methodologies, and robust decision-making frameworks. These approaches aim to address emerging systemic risks—including those exacerbated by the COVID-19 pandemic, geopolitical instabilities, and accelerating environmental change—and to develop practical, evidence-based strategies for ensuring the resilience and security of FEWSE systems. The collaborative efforts between NASU and IIASA have been instrumental in shaping the insights presented in this volume. With contributions from leading disciplinary institutes and research groups, this work integrates knowledge from academia, industry, policy, and community stakeholders. The research spans diverse methodologies, including stochastic optimization, machine learning, downscaling techniques, distributed model linkage, and robust estimation methods.
