    A COST-EFFECTIVENESS ANALYSIS OF ACTIONS TO REDUCE STREAM TEMPERATURE AT THE WATERSHED SCALE

    A cost-effectiveness frontier is developed to compare economic and environmental tradeoffs associated with planting a riparian buffer to reduce stream temperature at the watershed scale. Results indicate that total welfare change and its distribution among sectors vary between scenarios. The policy selected may differ if riparian plantings are voluntary rather than mandatory.Environmental Economics and Policy, Land Economics/Use,

    Potential Benefits of Remote Sensing: Theoretical Framework and Empirical Estimate

    The use of public funds has always been subject to public scrutiny and political log-rolling, but the intensity of this public scrutiny has not been higher any time during the past several decades than it is now. Partly this is due to the less favorable economic situation. However, the more important factors are (a) more awareness of the many public projects (welfare, housing, nutrition, pollution, transportation, etc.) and (b) better methods of accounting for costs and estimating of benefits of such projects. Thus, this high degree of public scrutiny can be expected to persist and perhaps intensify. Public scrutiny is particularly evident in relation to continued funding of efforts of developing space technology. Remote sensing largely falls into the category space technology, and it is, therefore, necessary to undertake technology assessment as it relates to remote sensing, if this public scrutiny is to be met successfully. It is the purpose of this paper to show that the basic theoretical framework exists for the estimation of social returns from research and applications of remote sensing. Further, it is the purpose to estimate the approximate magnitude (in dollars) of a particular application of remote sensing, namely the estimation of production of corn, soybeans, and wheat. Finally, some comments will be made on tile limitations of this procedure and on the implications of the results

    A Three-Stage Sample Model for Remote Sensing Applications

    Large-scale applications of remote sensing for the purpose of preparing crop estimates, natural resource inventories, disaster assessments, etc. for a given geographic region will, in general, involve questions of sampling, since complete coverage of the total geographic region and subsequent analysis of data collected with complete coverage appear technically and economically infeasible. This is true regardless of whether an aircraft, or a satellite is involved, and It applies equally to photography, multispectral measurements, radar, etc. Thus, even if remote sensing provided completely accurate data, estimates (of crop acreage, natural resources, extent of disaster, etc.) for the total region under study will be subject to an error, the so-called error of estimate. This error arises due to the fact that inferences based on selected observations within the region are drawn regarding the characteristics of the total region

    Enterprise Size Relationships in Agriculture

    My objectives for this seminar are not to make definite statements about size relationships either from a theoratical, methodological or from a more practical viewpoint. Rather my objective is to outline the extent of the problem. And l hope to be able to demonstrate to you that even to outline the problem is an undertaking of considerable magnitude
