      abstract = {The tasks involved n this study have included  understanding and describing programs, and designing and  using evaluative approaches.  These have required a variety  of skills, the input from and consultatiom with numerous  individuals both within and beyond the study team.   Among  members of the study team, Harvey Clark undertook many of  the tasks concerning obtaining and reporting questionnaire  results.  He also gathered informationr egarding all  programs, and performed a range of reserach and writing  functions.  J.H. Copeland was the link to successful  operation of long-period simulations with the EPIC model,  and esnured that the computing needs of the study were met.   P. Barlott prepared first drafts describing the farm fuel  rebate program and the farm tax assessment program.   Among  the major authors, J.A. Robertson contributed a knowledge  of soil fertility issues raised by the study.  M.S.  Anderson was primarily responsible for sections dealing  with Canada-Alberta crop insurance, Special Canadian Grains  program, drought assistance, Crown lands dispositions, and  water management programs.  In addition, he contributed to  all sections of the report (including in particular the  method for analyzing farmers' perceptions of the degree of  soil loss by program).  M.L. Lerohl, the princiapl author,  was responsible for several chapters of the report, and for  the methods used to arrive at estimates of soil loss and  the portion attributable to several programs, in particular  the Western Grain Transportation Act, CWB quotes, Western  Grain Stabilization and farm fuel rebates.    Others, many  outside the University of Alberta, also contributed in  important ways to the project.  Dr. V. Benson, of the  Agricultural Reserach Service of the U.S. Department of  Agriculture, was instrumental in providing access to the  EPIC mdoel.  In company with several of his colleagues, he  was gracious enough to field questions raised by neophyte  EPIC users.  Cesar Izaurraulde, University of Alberta, was  helpful in several ways, particularly concerning operation  of EPIC and in assisting access to relevant published  material.  E.W. Tyrchnieqicz counselled on issues related  to the study, and read and reacted to several sections of  the report.  G. Coen and J. Tajek, Agriculture Canada Soil  Survey Unit, provided basic soils data and professional  advice concerning land forms and soil characteristics.   Colleagues in the Department of Rural Economic were  sounding boards for issues as the developed, particularly  W.L. Adamowicz, J.J. Richter, T.S. Veeman and W.E. Phillps.   Members of the Steering Committee, R.Ada,, M. Boyle, B.  Colgan, S. Henderson, L. Fullen, L. Lyster, C. Ross and R  Wettlaufer provided useful comments both through formal  meetings as well as directly to the study team, and also  helped with data acess.  By no means least, Judy Boucher  not only typed the document with customary skill and speed,  but was also a useful critic of aspects of the report  presentation.  Only the most senior authors were  responsible for the errors and omissions which inevitably  remain.  We ask only the indulgence of readers in what we  believe is a somewhat innovative approach to measuring and  apportioning, to various public programs, the erosion  associated them.},
