<br />o <br /> <br />The effect the increased production over an area, <br />state, or region will have on the market price of <br />the product. <br /> <br />o <br /> <br />The costs of obtaining th~ additional precipitation. <br /> <br />o <br /> <br />Other related changes in the cost of production <br />and marketing. <br /> <br />o <br /> <br />Effects of possible shifts in tYpes of farming and <br />cropping related to the increased precipitation. <br /> <br />The South Dakota study concluded that for the State's <br />Southeast Crop Reporting District (a nine-county area), the <br />increased yields produced wit~ additional precipitation result <br />in increased benefits which are much greater than the costs. <br />Even with the assumption of price decrease and minimum yield <br />increases, increments in direct benefits are expected. <br /> <br />2.2.1.2 Montana. A report on economic impacts <br />in Montana notes that it is unlikely that every effect of rain- <br />fall due to cloud seeding will be anticipated, but efforts must <br />be made to predict as many changes and impacts as possible (16). <br />This investigation assumed that jmajor economic effects of <br />operational cloud seeding in Montana would occur in farming <br />and ranching, with secondary increases to overall regional <br />output and personal income. The study shows that many levels <br />of sophistication are possible in projecting changes in farm <br />yields and revenues from added rainfall. A realistic approach <br />considers timing, new prices corresponding to increased yields, <br />new optimal planting patterns, and proper separation of precipi- <br />tation effects from those of temperature and technology. <br /> <br />Study results indicate that an additional 10 percent <br />in growing season rainfall can be expected to increase net <br />farm revenues at least $10 million in Montana (1973 dollars, <br /> <br />2-4 <br />
