|Abstract or Summary
- The general objective of this study is to develop a systematic evaluation of the interrelationships between issues of the environment and economic growth for Tillamook County. In order to gain some appreciation for the complexities between environment and economic development; specific objectives were established 1) to identify relevant economic-ecologic linkage in Tillamook County and quantify these linkages for incorporation into the model, 2) to develop environmental impact business output and household income coefficients and 3) to indicate the use of the economic-ecologic model in environmental planning. Local communities who are concerned with the development can utilize the essential information of economic-ecologic model for assisting local decisions. However, the decision is framed in terms of trade-offs between changes in business outputs and/or household income and environmental consideration. For example, if biochemical oxygen demand (BOD) is a major environmental concern in the community then (BOD) produced per dollar of household income or business output is one criteria to be considered when evaluating potential expansion of business activity. If the community has options of influencing selection of wood processing; plywood mill, seafood processing or a salmon plant, the least BOD impact per dollar of output or income would be wood processing. If electricity is the major concern, wood processing uses the least electricity per dollar of business output but seafood processing uses the least electricity per dollar of household income, The community can see the need to clarify the goals. In general sense, the model provides alternative impacts for comparison when making local decisions concerned with development. By allowing comparisons, the locally most important trade-offs in environmental impact can be evaluated. The economic-ecologic model is adequate to estimate the impact of proposed developments. For example, if we know the basic expenditure pattern of the proposed new plant and its specific demand on local resources from an environmental stand point the economic-ecologic trade-offs can be estimated. The basic expenditure of the proposed salmon aquaculture development would contribute increase local economic activity, a portion of which would be to construction $13,000, to retail and wholesale sales $22,000, $6,000 in government taxes and payments to households of $65,000. Associated with this economic activity would be the following types of annual or local environmental loads: 780 pounds of particulates, 14,720 pounds of 5 Day BOD, 59 cubic yards of solid wastes and need for 1,148,010 gallons of water, and 307,260 kilowatt hours of electricity. The local challenge is how to evaluate the relative empacts and determine the preferred cause of development.
