1585 Bi-Vanes. This innovative system employs Bi-Vane data to determine the stability class of the atmosphere which enables computer atmospheric models to be used to determine the dispersion of pollution or nuclear material throughout an area. The Bi-Vane has many advantages over older systems, such as cost, less maintenance and easily achieved accuracy. Contact: Teledyne Geotech, 3401 Shiloh Road, Garland TX 75041, U.S.A.
DOPPLER
SODAR
SYSTEM
Our Doppler Sodar system measures a vertical profile of wind speed, direction, thermal stratification and turbulence parameters (sigma W, sigma Teta) from 40 m to 1000 m or more above ground. Recent tests indicate it is the only Sodar capable of continuous real time operation without exhaustive human post processing and quality control. Our Fluxmeter is a sophisticated micrometeorological station which not only routinely measures the classical meteorological parameters, but also the turbulent fluxes close to the ground (heat flux, Reynolds stress, pollution flux etc.). It can be used in pollution networks, for agricultural research and for chemical warfare studies as well as for laser propagation monitoring. Since October 1985 Remtech has been manufacturing a new product, the R.A.S.S. (Radio Acoustic Sounding System) which remotely measures temperature profiles in the first 1000 m of the atmosphere. This system is the only commercial available system in the world and provides resolution to 0.2°C. It can be used in environmental studies for temperature gradients, and for monitoring how the propagation of radio waves is modified by atmospheric conditions. Remtech currently has 83 Doppler Sodars and 13 Fluxmeters working or on order throughout the world, for environmental monitoring, military applications and atmospheric research.

REVIEW
Sustainable Environmental Management (edited by R. Kerry Turner). Westview Press Boulder, CO; Bellhaven Press, London, 1988 in association with ESRC. 292 pp., over 50 tables and diagrams, just over 2 pp. subject index, £27.50. The book comprises 11 chapters written by 12 authors all working in the U.K., one at the Department of the Environment and the rest in universities. It begins with an overview on sustainability, resource conservation and pollution control by the editor, who also co-authors a chapter on 'Resource Conservation, Sustainability and Technical Change' with D. Deadman in Part 1 which deals with sustainable growth and development principles. The other chapters in that section are 'The Politics of Sustainability' by T. O'Riordan, 'Economic Models and Environmental Values: A Discourse on Theory' by M. Redclift, 'The Sustainable Use of Natural Resources' by D. Pearce and C. Nash and J. Bowers. Bowers also authors a chapter on 'Cost Benefit Analysis in Theory and Practice: Agricultural Land Drainage Projects' in Part 2 on Sustainable Growth and Development Practice. The other chapters in this section are 'Towards a Second Green Revolution in the Tropics: From Chemicals to New Biological Techniques for Sustained Economic Development' by S. Ghatak, 'Pollution Control Objectives and the Regulatory Framework' by J. Rees, 'Market Mechanisms of Pollution Control: Polluter Pays, Economic and Practical Aspects' by J. Pezzy and 'Valuation of Wildlife: A Case Study of the Upper Teesdale Site of Special Scientific Interest and Comparison of Methods in Environmental Economics' by K. G. Wills and J. F. Benson. The foreword, by Professor O'Riordan, explains that the book is the product of the work of the group set up in 1983 by the U.K. Economic and Social Research Council to study environmental economics. In the present political climate in the U.K., where it is fashionable to express all values in monetary terms, i.e. as market values, it is inevitable that there will be attempts to evaluate the monetary value of marshes, forests, wildlife and other features of our natural environment compared with those of the 'developed' environments which have displaced, or may displace them. Clearly, such valuations will depend upon one's view of the world and we find that this may be 'cornucopian', 'accommodating', 'communalist' or 'deep ecology'. Although the authorship is predominantly British, at least by workplace, the book does address squarely the perhaps insoluble problem, in a world of finite resources and limited capacity for assimilating waste, posed by the aspirations of the developed countries to maintain and even improve their existing lifestyle, and the aspirations of the developing countries not only just to survive, but also to attain an equally desirable or hopefully better lifestyle. Again one's concept of a satisfying lifestyle depends upon one's view of the world and one's perception of relationships with other people and other lifeforms. The book has a hard cover and is typeset with clear diagrams and what appears to be an adequate bibliography at the end of each chapter. Readers of this Journal who are not economists or social scientists, and that probably means most of us, who wish to see how their work fits into the broader context of sustainable growth policy and sustainable development strategies will, I believe, find this book very interesting reading.
