Book excerpt: The context in which environmental policy decision-making occurs has changed, resulting from widening environmental problems, increased demands from groups and citizens, continuing pressure on the continent's resources and normative shifts. The complexity of current issues is related to an even broader contextual shift: the globalization of environmental issues exacerbated by trade liberalization, especially on a regional level and the potential contradictions between trade and the environmental international agenda that this implies. This volume studies the new dimensions of resource conflict between Canada and the United States, accounting for the emergence of new bilateral environmental issues and detailing how trade liberalization has fostered both disputes and policy convergence. It also examines the recent shifts in America towards a unilateral foreign policy and how this affects active Canadian diplomacy Ideal as a resource tool for students and academics, this book will be a key resource in the areas of global governance, US-Canadian foreign policy and environmental policy.
