Today's most pressing environmental problems are planetary in scope, confounding the political will of any one nation. How can we solve them? Global Environmental Governance offers the essential information, theory, and practical insight needed to tackle this critical challenge. It examines ten major environmental threats - climate disruption, biodiversity loss, acid rain, ozone depletion, deforestation, desertification, freshwater degradation and shortages, marine fisheries decline, toxic pollutants, and excess nitrogen - and explores how they can be addressed through treaties, governance regimes, and new forms of international cooperation. Written by Gus Speth, one of the architects of the international environmental movement, and accomplished political scientist Peter M. Haas, Global Environmental Governance tells the story of how the community of nations, nongovernmental organizations, scientists, and multinational corporations have in recent decades created an unprecedented set of laws and institutions intended to help solve large-scale environmental problems. The book critically examines the serious short-comings of current efforts and the underlying reasons why disturbing trends persist. It presents key concepts in international law and regime formation in simple, accessible language, and describes the current institutional landscape, as well as lessons learned and new directions needed in international governance. Global Environmental Governance is a concise guide, with lists of key terms, study questions, and other features designed to help readers think about and understand the concepts discussed.
