Book excerpt: Environmental Impact Assessment presents the proceedings of the Seminar on Environmental Impact Assessment that took place in Villach, Austria in September 1979. The rapid pace in technological and economic development led to detrimental effects on the environment. In this regard, it is imperative that policies are formulated in order to avert future environmental damage. The forum seeks to develop methods, procedures, techniques, and policies on Environmental Impact Assessment, a concept whose time has come. The seminar is attended by an array of international experts, leaders, agencies, and organizations to discuss various issues on Environmental Impact Assessment. The seminar begins with a paper on the main procedural and institutional questions related to environmental impact assessment, which intends to be the jumping board for further discussions on the matter. Papers on the qualitative and quantitative methods of environmental analysis; integration of environmental considerations into the planning and decision-making process; public information and participation; problems with the international aspects of environmental impact assessment; and case studies are presented. In the end, the participants adopted a set of conclusions and recommendations, which are reproduced in full. Environmentalists, ecologists, policymakers, government and private planners, political leaders, scientists, and concerned people will find this book invaluable.
