IMPLAN, a computer-based system for developing nonsurvey input-output models, was used to analyze the impacts of Resource Conservation and Development (RC&D) activity in the Nebraska Panhandle area for 1971-88. The impacts resulted from both the goods and services purchased from the local economy and through the flow of outputs from RC&D program activities. The expenditures and outputs of direct project measures included in the analysis were critical area treatment, recreation construction, irrigation construction, floodwater prevention construction, Federal and State salaries, State and local enterprise expenditures, recreation visits, and floodwater reduction benefits. This report also analyzes the impacts of two associated project measures: conservation research and the promotion of local facilities for conventions.
