This is a report of a research activity in progress. As such, this research is a part of a larger research effort by Resources for the Future, Inc. in which an attempt is being made to (1) evaluate alternative demand projections for U.S. crop, animal and forestry products to the end of this century, (2) to translate these projections into demand by major producing regions for land, water, fertilizers, pesticides and other inputs with potentially important impacts in the environment, (3) to assess the nature and importance of these environmental impacts and (4) to discuss principal policy issues suggested by the analysis as well as problems needing additional research. The research being done at Missouri is directed toward the examination of the demand for pest control techniques that may be used over the next decade or so to control pests in grain crops and soybeans.
