Can environmental institutions be effective in bringing about a healthier environment? How? "Institutions for the Earth" takes a close look at the factors influencing organized responses to seven international environmental problems - oil pollution from tankers, acid rain in Europe, stratospheric ozone depletion, pollution of the North Sea and Baltic, mismanagement of fisheries, overpopulation, and misuses of farm chemicals - to determine the roles that environmental institutions can play in furthering the case of environmental protection. The contributors identify three major functions performed by effective international environmental institutions: building national capacity, improving the contractual environment, and elevating governmental concern. The international organizations analyzed within this framework include the United Nations Environment Program, the Intergovernmental Maritime Organization, the Food and Agriculture Organization, numerous fisheries commissions, the Commission for Europe, the Oslo and Paris Commissions, the Helsinki Commission and the United Nations Fund for Population Assistance.
