Methods used for regional development analysis are employed mainly to make forecasts and comparisons. Forecasting models of various types (e.g. econometric models) are usually used for forecasting. Recently, vector-autoregressive models (VAR) have become popular. These models were proposed by Sims in 1980. On the contrary, taxonomic methods (that are in the center of attention as far as the present publication is concerned) are most often employed to make comparisons. Linear ordering methods, including standard methods, are the most popular among ta- nomic methods. They are based on different distance and similarity measures, which leads to the fact that they do not always provide reliable information. When, for example, one construes the standard for a base year and then compares it with data for other years, it may turn out that the measure determined will have worse values than the standard for a real object (region, micro region) although this object is better from the standard. Hence, one must look for new methods employed in regional development analysis or improve hitherto existing ones in such a way so that information obtained re?ects the reality to a larger extent. The main aim of the present publication is to work out methodological basis for regional development analysis based on vector calculus together with assumptions about computer system supporting the implementation of the method suggested.

We must enhance the effectiveness ofland stewardship and management of the world's natural resources to meet a growing global population's need for conservation, sustainable development, and use of land, water, and other natural resources. Ecosystem-based, mul tiple-use land stewardship is necessary when considering the present and future uses ofland, water, and other natural resources on an operationally efficient scale. We need holistically planned and carefully implemented watershed management practices, projects, and pro grams to accommodate the increasing demand for commodities and amenities, clear water, open space, and uncluttered landscapes. An international conference in Tucson, Arizona, from March 13 to 16, 2000, examined these needs and increased people's awareness of the contributions that ecosystem-based, multiple-use watershed management can make to future land stewardship. The conference was sponsored by the School of Renewable Natural Resources, University of Arizona; the College of Agriculture, University of Arizona; the Rocky Mountain Research Station, USDA Forest Service; the Research Center for Conservation of Water Resources and Disaster Pre vention, National Chung-Hsing University, Taiwan; the Department of Forest Resources, University of Minnesota; the Center for Integrated Natural Resources and Agriculture Man agement, University of Minnesota; the Centro de Investigaciones Biologicas del Noreste, Mexico; the International Arid Lands Consortium; the USDA Natural Resources Conserva tion Service; the Bureau of Land Management of the Department of the Interior; the Salt River Project, Phoenix, Arizona; the Southern Arizona Chapter, Southwestern Section of the Society of American Foresters; and IUFRO Working Party 8. 04. 04, Erosion Control by Watershed Management.
Indexes material from conference proceedings and hard-to-find documents, in addition to journal articles. Over 1,000 journals are indexed and literature published from 1981 to the present is covered. Topics in pollution and its management are extensively covered from the standpoints of atmosphere, emissions, mathematical models, effects on people and animals, and environmental action. Major areas of coverage include: air pollution, marine pollution, freshwater pollution, sewage and wastewater treatment, waste management, land pollution, toxicology and health, noise, and radiation.
