11 Preface Risk Management and the Environment: Agriculture in Perspective is a modern academic work that seeks to bring out both to the private and the policy sectors the importance of risk management in relation to the environment in agriculture, as the world moves towards freer markets. Many efforts were pooled together in making this book. Three years ago, an attempt was made by one of the editors to get a project on 'Agricultural Risk Management and Sustainabilty' (ARMAS) funded by the European Commission. Probably deeming the proposal as prematurely novel for Europe, the Commission's screening experts abandoned its evaluation. Following that experience it became apparent that the literature on the theme ought to be strengthened and emphasized through a book by a well known publishing house. The editorial team was formed relatively quickly and an invitation to known experts in the field for contributions was issued. Subsequently, Kluwer Academic Publishers, evaluated an edited volume proposal package, and final revisions were made prior to submitting the entire manuscript for publication. We are gratefully acknowledging the moral support of several individuals as well as the patience of our publishers. Rethimno, Crete, June 2002 Bruce A. Babcock, Robert W. Fraser, Joseph N. Lekakis
