If you’re not too daunted by its size (it tops out at just over 400 pages), the Dictionary & Introduction to Global Environmental Governance serves as a useful primer on international environmental politics and policies. This volume could be particularly useful to those working in related, but distinct, sectors who want to familiarize themselves with global environmental governance’s history and recent developments. Ever wondered what an epistemic community is? What makes water soft or hard? Curious to see the authors attempt to define “environment” and “ecology”? This book answers all these questions and many more, and most definitions are distinguished by admirable clarity and brevity.
