<br />0!l2~31 <br /> <br />result in reduced labor requirements. However, projections of overall econom- <br />ic activity can be taken as being on the high side. <br /> <br />Primary Sectors <br /> <br />Coal mining and conversion alternatives are assumed as part of the pos- <br />sible energy-development proposals, with the agriculture scaled according to <br />the resource availabil ity after mining, conversion, and secondary sectors are <br />taken into consideration, In the basin assessment, interactions between in- <br />creased coal-resource and agricultural developments must be weighed against <br />preserving the physical features of the basin fora variety of recreational <br />uses which contribute significantly to the regional economy. Physical and <br />economic resource information will be adapted from State reports, other fore- <br />casts, or the University of Coloradots input-output model (Udis and others, <br />1973) , <br /> <br />It is assumed that individual plants and the coal-transportion facilities <br />will already exist'at the projected 1990 levels in order to minimize new con-' <br />struction activity and secondary development from this construction activity. <br />That is, we are assuming that the physical facilities and employment bases <br />will have developed sufficiently by 1990 to support the assumed level ofmin- <br />ing-conversion activity so that by then new construction activity for coal-' <br />deve 1 opment re lated fad] it ies will be m in i ma 1. <br /> <br />In summary, by working backwards from a specified final demand for coal <br />and conversion activities, the agricultural activities are calculated. From <br />an input-output type of analysis, assuming a fixed set of mines and plants <br />with a fixed set of technologies, primary sector employment and other input <br />demands are calculated, From the employment and other demographic and insti- <br />tutional information, the total population forecasts can be made, along with <br />demand for secondary sectors. The level of secondary sector activity will be <br />based on the current proportions or ratios implied by the most recent version <br />of the input-output model adapted for the Vampa River basin, <br /> <br />Secondary Sectors <br /> <br />Secondary economic sectors broadly include services, local government, <br />transportation, retail commerce, and finance, Depending upon the level of de- <br />tail required and avai labie, the retai i commerce and financial sectors can be <br />combined. Services, local government, and transportation sectors also can be <br />combined, The general mix between the various secondary se~tors then may be <br />assumed to be the same as either the present mix for the Vampa River basin or, <br />more logically, the observed mix in a "typical" energy-development region, <br />The level of activity in the supportive industries will be determined by the <br />income and employment generated by the primary sectors. <br /> <br />In order to simplify the analysis, itwill be assumed that no primary or <br />secondary manufacturing industries are generated by the mining and energy de- <br />velopment in the particular region of the Vampa River basin, Although this <br />may be underestimating the potential for development, the generated environ- <br />mental impacts will represent conservative estimates, <br /> <br />13 <br /> <br />. <br />
