  8. Simulating the Adoption of Soil Conservation Management Systems Under the Conditions of Uncertainty (Erosion, Control)

    Soil conservation has become a key issue in the U.S. in the 1980's. There is increasing concern for the continuing problem of soil erosion. Since conservation involves a planning horizon of more than one year, risk and uncertainty enter into the plans. Over time it is difficult to predict farm …
