<br />6,,60 <br /> <br />high variability due to weather, water supply, and irrigation <br />water management, Therefore, there will be less reliability <br />in the early-year data than will be realized from the <br />grouped observations made throughout the study, Be- <br />cause of this, it is important that commitment be made to <br />the monitoring and evaluation effort for the full time <br />period, <br /> <br />. <br />impacts of practices ,and treatments with nonparticipating <br />farmers. Because landowners are known to go through a <br />technology adoption process that depends heavily on <br />evaluation by neighbors, the availability of this information <br />early in the project could materially affect the rate of adop- <br />tion among those farmers who can be shown a high <br />likelihood of obtaining positive net personal benefits, <br /> <br />The data collected from case studies will gain increased <br />reliability through replica\ion on other farms and through <br />increased years of record, By the midpoint of the study <br />period, this increased reliability should allow the inves- <br />tigators to begin to array practices in terms of their cost <br />and marginal contribution to salinity reduction and im- <br />proved net personal income, <br /> <br />, It will be difficult to determine the extent to which the <br />project is achieving planned accomplishments except on an <br />annual basis. After a few years, it should be possible to <br />place a reliable, estimate on the extent to which the <br />achieved rate of progress and expenditure agrees with the <br />planned rate of progreSs and expenditure, and whether the <br />project's actual costs and accomplishments will match the <br />planned costs and accomplishments. <br /> <br />At the midpoint in the inventory and evaluation period, it <br />should also be possible to begin making inferences about <br />the marginal productivity of project funds spent over time. <br />It is expected that during the early years, project funding <br />will be relatively low. Funding then should increase sig- <br />nificantly with an increase in landowner adoption rate, <br />This should be followed by a decline, as the best oppor- <br />tunities are fully exploited. Analysis of this time-series <br />data should offer opportunities to reduce project imple, <br />mentation and avoid investment of Federal resources in <br />areas that are not cost effective. <br /> <br />After this project midpoint, it may be possible to use these <br />data to develop program management or policy steps that <br />will concentrate project efforts on those practices having , <br />the most cost effective rate of accomplishment of project <br />goals, These policy and management steps could include <br />differential cost -share rates, cancellation of ineffective or <br />inefficient practices and targeting work with specified farm <br />types, sizes, or irrigation systems. <br /> <br />Early in a study it should be possible to begin using case- <br />study results in discussing observed adverse and beneficial <br /> <br />Reports should be produced throughout the mooitoring <br />and evaluation period, For each case study, a com- <br />puterized report of the results should be printed in the <br />first year and updated each year, These reports should be <br />available for planners to use in working with landoWners. <br />Annual reports of project economic accomplishments <br />should be produced starting with the second study year. <br />These reports should have a standard format to fac.ilitate <br />project comparisons. Special reports concerning <Xlm- <br />parison of expected performance with planned perfor- <br />mance, potential performance over time, and incremental <br />performance of individual practices can be produced from <br />about the midpoint on, A major report SUlIllllarizing all <br />economic performance, interpretations, and inferences <br />should be produced in the last year of the monitoring and <br />evaluation activity. <br /> <br />The second major category of results will be estimates of <br />the degree to which treatment application, and therefore <br />salinity reduction, can be accomplished on the entire <br />population of farmers in the basin. Using sample data, it <br />can be determined how the structural ~araCteristics of the <br />participating farms compare with the nonparticipants, and <br />simi1arities will indicate the extent to which physical ,and <br />economic data concerning participant farms can be <br />, expanded to the entire population. <br /> <br />24 <br /> <br />25 <br />
