The Journal of Environmental Management publishes papers on all aspects of management and use of the environment, both natural and man-made. As governments and the general public become more keenly aware of the critical issues arising from man's use of his environment, the journal aims to provide a forum for the discussion of environmental problems around the world and for the presentation of management results. It is aimed not only at the environmental manager, but at everyone concerned with the wise use of environmental resources. The journal tries particularly to publish examples of the use of modern mathematical and computer techniques and encourages contributions from the developing countries in the Third World.
