Part of a United Nations University research initiative, the Clark-based Project on Critical Environmental Zones publishes Regions at Risk: Comparisons of Threatened Environments, an international, interdisciplinary report exploring nine regions facing large-scale, human-induced environmental changes. Editors are Jeanne X. Kasperson, research associate professor and research librarian for the George Perkins Marsh Institute, and geography professors Roger E. Kasperson and Billie Lee Turner. “In nearly all these regions, trajectories of change are proceeding to greater endangerment, sometimes rapidly so, while societal efforts to stabilize these trajectories and to avert further environmental deterioration are lagging,” they conclude.
