This book advances our understanding of security and its intricate interactions with geopolitics and the environment in Eurasia.Norman A. Graham and Åuhnaz Yılmaz focus on Eurasia, where the energy-water-food nexus has emerged as a vital aspect of political economy and increasinglyas a decisive factor for human security. As clearly revealed during the Russian invasion of Ukraine, this nexus rests on a precarious balance. Graham and Yilmaz argue that Central Eurasia is currently "Running on Empty" and highlight the key environmental challenges, including water quantity and quality and food security. The authors draw on their extensive fieldwork in countries including Azerbaijan, China, Georgia, Kazakhstan, the Russian Federation, Turkey, and Uzbekistan to assess the interests and impact of pivotal actors and evaluate the competition and complementarities of these actors regarding water, energy, food security, and foreign policy imperatives. They also examine the broader interaction and implications of security at multiple levels by analyzing the local, national, and international factors in light of geopolitical and environmental challenges.Taking a novel and highly interdisciplinary approach, this book will be an important resource for students and scholars of energy and food security, political economy, international conflict and cooperation, and natural resource politics.
