The papers in this book were 'in a preliminary version' presented at an international con ference May 21-25, 2002 in Gilleleje, Denmark. It was a joint event, namely the biennial meeting of the Scandinavian Society of Forest Economics and the 3rd Berkeley-KVL Con ference. The Scandinavian Society of Forest Economics (SSFE) was established in 1958 as a forum for forest economists in the Nordic countries to meet and exchange ideas on research and education. Alternating between Denmark, Finland, Norway and Sweden, biennial ordinary meetings have taken place ever since. The number of participants has increased from 10-15 in the first decade to more than 80 in 2002. In the last two decades prominent researchers from outside Scandinavia have been invited to present papers at the biennial meetings and also to participate in ad hoc working groups. The Berkeley-KVL part of the conference is based on a research collaboration between The Royal Veterinary and Agricultural University (KVL), Copenhagen, University of Cali fornia at Berkeley, and Oregon State University. It was initiated in 1993 within the frame work of a research programme at KVL: 'Stochastic Decision Analysis in Forest Manage ment' and since 1996 extended to the programme 'Economic Optimisation of Multiple-Use Forestry and Other Natural Resources'."

Plant disease is one of the greatest causes of economic losses of crops throughout the world. Every year, billions of dollars are spent on chemical control measures, but there is an increasing awareness that alternatives to these chemical control measures may be becoming more viable. This work explores the international impact of plant disease on man and how this is measured and diagnosed, discusses epidemiology and the genetics of host-parasite relations and looks at the range of defensive tactics currently available and those under development, in particular those which are more environmentally acceptable than many in widespread use now.
Introduction to Plant Pathology provides an integrated coverage of the biology of plant disease, highlighting the organisms that cause such diseases and the techniques used for their identification and control. It is a comprehensive, up-to-date introduction to the subject, including the latest relevant molecular and genetic developments. Broadly divided into two parts, the text opens by placing plant disease in context, showing how disease may cause a catastrophic loss of crops. Pathogens are then discussed alongside epidemiology and the measurement of disease severity and its relation to yield and inoculum control. The second part examines host-pathogen interactions and symptoms caused by altered plant growth regulator metabolism. Finally, the book looks at how the health of crops may be improved through the continuing development of control measures that are environmentally responsible.
Although the United States is a nation founded by immigrants, Alberto Gonzales and David Strange believe that national immigration policy and enforcement over the past thirty years has been inadequate. This failure by federal leaders has resulted in a widespread introduction of state immigration laws across the country. Gonzales and Strange assert that the solution to current immigration challenges is reform of federal immigration laws, including common sense border control, tougher workplace enforcement, minor (but significant) changes to the Immigration and Nationality Act, and a revised visa process that discourages overstaying the duration of a visa. Gonzales and Strange embrace many provisions of current pending legislation, but are sharply critical of others. Their proposals call for an expansion of the grounds of inadmissibility to foster greater respect of law and to address the problem of visa overstays, while also calling for a restriction on grounds of inadmissibility in other areas to address the large undocumented population and increasing humanitarian crisis. They explore nationality versus citizenship and introduce a pathway to nationality as an alternative to a pathway to citizenship. This immigration policy blueprint examines the political landscape in Washington and makes the argument that progress will require compromise and the discipline to act with compassion and respect. Most significantly, it illuminates how following this blueprint can enhance national security and improve the economy in the United States in ways that is consistent with the rule of law.
