This book is the result of a three day workshop on "Evaluation in theory and practice in spatial planning" held in Ramsey Hall, University College London, in September 1996. Some 30 people from 8 different countries attended and 20 papers were presented. The majority of them now form the basis for this book. This occasion was the third on the topic, the two preceding having taken place in Umea in June 1992 and in Bari in 1994. Following these three meetings, we can now say that this small, industrious, international family really enjoy meeting up from time to time at each others places, in the presence of older members and new children, each one presenting his/her own recent experiences. It particularly enjoys exchanging views and arguing about the current state and the future of evaluation in spatial planning (all families have their vices ... ). It is also pleasing to see these experiences and discussions resulting in a book for those who could not attend and for the broader clan in the field. Not long time ago, but ages in the accelerated academic time scale, evaluation in planning established its own role and distinct features as an instrument for helping the decision-making process. Now this role and these features are exposed to major challenges. First, the evolution of planning theory has lead to the conception of new planning paradigms, based on theories of complexity and communicative rationality.

This is a work summarizing in one volume the pioneering approach of the author to public-interest decision-taking in the field of urban & regional planning. This book is aimed at students, researchers and professionals in planning. Nathaniel Lichfield first introduced in his "Economics of Planned Development" the concept that, in any use and development of land, the traditional "development balance sheet" of the developers needed to be accompanied by a "planning balance sheet" prepared by the planning officer or planning authority. Over the forty years since this work was published, the author has brought to the operational level the "planning balance sheet," with many case studies, primarily for consultancy purposes. The present title reflects the incorporation during the 1970s of the then emerging field of environmental impact assessment.

The role of economics in urban conservation is relatively underdeveloped. Professor Lichfield has added to his other pioneering studies in this innovative and important exposition of approach, method and techniques for the systematic application of economics in the conservation of urban areas. In order to establish an appropriate base for the economic analysis and application in parts III, IV and V of the book, the opening sections provide essential background information about the management and planning for conservation in the urban system in general and examine the special place of the cultural built heritage: those building and objects chosen by society for particular protection. Written in a highly accessible style, Economics in Urban Conservation makes a major contribution to an understanding of how economics in conservation can help in achieving a sensible balance between continuity and change in the built environment.
