Two major trends are currently challenging the sustainability of human civilization: extreme inequality and the ecological crisis. This book argues that these are intrinsically linked by further exploring the complex relationships between global ecological crises, neoliberal globalization, orthodox development policies, and imperialism. Drawn from extensive theoretical, historical, policy, and empirical research, as well as fieldwork in Africa and Asia, this book examines the crucial characteristics of the capitalist world-system and how it enables and drives ecological imperialism. Neoliberal globalization has allowed for capital’s unfettered access to and exploitation of Nature across the planet, and neoliberal development policies have reinforced a contemporary form of ecological imperialism where the environments of the Global South are enclosed and exploited, and local communities are dispossessed of their land and livelihoods. Simultaneously, resources from the Global South are funneled to the Global North in the form of consumer goods and ecologically unequal exchange, while the profits from those resources are siphoned away to transnational corporations, financiers, and government elites. This work traces the historical development of free market policies, while also paying special attention to the role of Northern international financial institutions, emerging economies (the semi-periphery), and the often-hidden role of international finance in ecological imperialism. This volume will be of keen interest to scholars and students of political economy, critical development studies, environmental sociology, and political ecology.
