Presents a method of determining environmental improvement by calculating a ratio of the measurement of environmental quality before and after an improvement project. Applies the method for four case studies in South Wales. (TW)

Discusses some of the variables affecting environmental decision making. Addresses ecological, legislative, cultural, political, and economic forces that influence such processes. Urges more attention to the contextual basis of environmental decision making. (TW)

Summarizes the blueprint for environmentally sound development, which was endorsed by the Governing Council of the United Nations Environment Program in June 1987. Includes recommendations on a World Food Bank, satellite communication costs, labelling toxic chemicals and pesticides, and water quantity and quality. (TW)

Examines some of the traditional and new methods that have been devised to harness energy from the sun in the form of heat. Discusses some current research and developments underway which are lowering the costs of equipment and installation. (TW)

States that tidal power projects are feasible in a relatively limited number of locations around the world. Claims that together they could theoretically produce the energy equivalent to more than one million barrels of oil per year. (TW)

This book was developed to highlight the risks that confront societies, and to indicate the most promising avenues for preemptive policies and actions. The document contains chapters on: (1) the emergence of change; (2) analyzing demographic factors; (3) assessing the future of urbanization; (4) reassessing nuclear power (including an analysis of…

Describes Ocean Thermal Energy Conservation (OTEC) as a method for exploiting the temperature difference between warm surface waters of the sea and its cold depths. Argues for full-scale demonstrations of the technique for producing energy for coastal regions. (TW)

Discussed are the costs of deriving energy from the earth's natural reserves of salt. Argues that, as fossil fuel supplies become more depleted in the future, the environmental advantages of salinity power may prove to warrant its exploitation. (TW)

Claims that the exploration of geothermal energy has a somewhat marginal role to play today in the overall world energy budget. Discusses the applicability, however, of geothermal heat to some national and local energy developments. (TW)

Suggests that wind energy for electrification will prove to be an appropriate technology with very positive socioeconomic benefits, especially in developing countries. Provides examples of projects conducted by a Danish wind research laboratory. (TW)

This document summarizes the proceedings of an international conference on environmental education which was organized jointly by Unesco and the United Nations Environment Programme (UNEP). The conference attracted 300 participants and observers from 80 countries, including experts and representatives of 15 international and national…
